Historical past and Cultivation
These beautiful flowers have been cultivated for hundreds of years for his or her decorative worth and medicinal properties. Within the Renaissance period, the showy flowers grew to become common decorative vegetation. Kids and gardeners grew to become fascinated by the best way the jaw of the flower “snaps” shut when gently squeezed.
Within the 18th and nineteenth centuries, botanists got interested within the advanced floral construction and got down to develop new varieties. We will see this range in a whole lot of cultivars from seed firms immediately. They principally match into one in every of two flower varieties: the normal “mouth-type” snapdragon or the open-face “butterfly” kind. We’ll discover extra fascinating seed cultivars beneath.
What’s a Snapdragon?
Snapdragons, or Antirrhinum majus, are short-lived tender perennials that flower in cool climate. These beautiful, colourful flowers are sometimes grown as annuals within the cool buffer seasons of spring and fall.
The frequent identify comes from the dragon-shaped flowers that seem to have two closed lips raised on a terminal spike. The scientific identify Antirrhinum comes from the Greek anti, which means “like,” and rhis, which means “nostril,” a reference to the dragon-snout look of every flower.
The place Do Snapdragons Originate?
Snapdragons are a cool-weather annual flower native to the Mediterranean in southern Europe, northern Africa, and the Center East. Within the Renaissance period, snapdragons grew to become more and more common in Europe and captured the eye of botanists and florists, who unfold the colourful blooms throughout the globe.
Their pure habitat contains rocky slopes, open fields, and typically disturbed roadsides. They love well-drained soils with delicate sunny climate. The intriguing floral shows sometimes dwindle in sizzling summers above 80°F however return to their full glory within the cool climate of fall.
Propagation
Snapdragons could be propagated from seeds, cuttings, or by division. Seed is the commonest technique of multiplying these vegetation. Nonetheless, you’ll be able to’t save seeds from many hybrids resulting from plant patents or cross-pollination, leading to offspring that isn’t true-to-type. Fortuitously, an unlimited vary of beautiful snapdragons can be found from seed firms, together with our personal Botanical Pursuits.
Seed
Snapdragon seeds are remarkably tiny. Whereas they are often straight sown in your backyard, many gardeners choose to start out them indoors to get a soar begin on the gardening season. No matter your chosen methodology, be very cautious to not bury the seeds. Snapdragons require mild to germinate.
Direct Seeding and Chilly Publicity
You possibly can direct sow snapdragons outdoors in early spring in chilly climates or late summer season and early fall in delicate southern climates. Direct seeding naturally exposes the seeds to a chilly stratification interval. This implies the seed is uncovered to chilly soil temperatures beneath 40°F; because the climate warms within the spring, the change in temperature triggers germination within the seed.
Chilly publicity improves germination and mimics the plant’s pure winter dormancy cycle. Nonetheless, most lower flower gardeners and farmers choose to place these tiny seeds within the fridge moderately than throwing them outdoors within the components. Wind and heavy rains can simply displace the seeds and hinder your germination success.
Beginning Indoors
Within the depths of winter, chill snapdragon seeds for 3-5 weeks in your fridge to enhance germination earlier than sowing. Then, begin seeds indoors 8-10 weeks earlier than your anticipated final frost date. If you happen to’d wish to skip the fridge chilling, begin seeds open air 8-10 weeks earlier than your anticipated final frost date; the cooler out of doors temperatures will stratify the seeds on their very own!
Fill cell trays or 3-inch pots with a well-drained soil mix and really shallowly surface-sow the teeny tiny seeds. Cowl with an ultra-fine mud of soil or vermiculite. Mild is required for snapdragon germination, so the soil ought to solely be sufficient to carry the seeds in place with out burying them.
Moisture
Keep constant moisture through backside watering or misting. You don’t need to pour a number of water excessive of the trays, as this will displace the seeds. On the similar time, you don’t need the floor soil to fully dry, both — it should keep damp to the contact!
Place your seed trays in a brilliant, sunny window or greenhouse nursery. Seedlings normally take 7 to 14 days to germinate at room temperature, however some varieties can take as much as 3-4 weeks. Once more, chilly stratification can velocity up the method.
There isn’t any want for heating mats or extraordinarily sizzling environments, as these seeds are naturally tailored to chill climate. Once they emerge, develop at a constant 60-70°F for 3-4 weeks.
Pinching
When the primary units of true leaves seem, transplant them to bigger containers if desired. When the vegetation have at the least 4-6 units of leaves, many growers pinch them again to half their peak. If the plant is 4 inches tall, you’ll be able to pinch the middle right down to 2 inches.
Pinching delays flowering, nevertheless it encourages a bushier plant with extra facet branches. If you happen to choose one central floriferous stalk, don’t pinch. However if you’d like a dense floral present, pinch the seedlings and plant at a barely wider spacing to permit for branching.
Reducing
For the quickest outcomes, snapdragons are sometimes multiplied through cuttings. The very best time to take cuttings is in early spring (in case you have a longtime plant) or about six weeks earlier than the primary fall frost in milder climates.
For this methodology, you want a wholesome mom plant of the specified selection. The cuttings can be genetically similar to the unique plant. You possibly can root them in water or moist soil, and each strategies are likely to have nice outcomes. This methodology works for hybrids that don’t produce true-to-type seeds, too!
To take snapdragon cuttings:
- Begin with a wholesome, sturdy plant that isn’t flowering.
- Find a leaf node or the small bump the place a leaf intersects with the stem.
- Use sharp, sanitized pruners to chop 4-6” lengths of stem just under the node.
- Take away the leaves from the decrease half of every stem.
- Dip the top of every slicing in a rooting hormone.
- Place the stems in cell trays or pots stuffed with well-drained soil combine.
- Alternatively, submerge the decrease half of the stems in water.
- Maintain 2-3 units of remaining leaves above the soil or water stage.
- Place the cuttings in direct mild till the roots develop.
Cuttings can take 2-3 weeks to type roots. Recent new inexperienced shoots are a terrific indicator that the slicing has taken root. You can even gently tug it from the bottom and really feel for a slight resistance. If the stem stays put, it in all probability is able to up-pot to a bigger container the place it may possibly develop till you transplant it open air.
To get essentially the most “bang in your buck,” you’ll be able to use your “pinched” tops from seedlings or established vegetation as new cuttings. This offers you a double whammy of advantages as a result of the pinched vegetation will develop bushier, and the eliminated stems gained’t go to waste as a result of they’ll develop into new vegetation.
Root Division
Division is a much less frequent methodology of propagation snapdragons, nevertheless it’s nonetheless a dependable strategy to multiply your vegetation. The very best time to divide a snapdragon patch is in late summer season when the plant has stopped flowering. You possibly can propagate a container-grown snapdragon any time it isn’t in bloom.
To divide a mature snapdragon:
- Gently dig up your entire plant in late summer season.
- Use sanitized pruners, a knife, or your palms to separate the foundation mass into smaller components.
- Guarantee there’s foliage hooked up to every part of roots.
- Plant every division in a 1-gallon pot or find a special backyard mattress.
- Keep constant moisture and search for new development inside 2-4 weeks.
Dividing can assist skinny out an overcrowded snapdragon patch or increase your container flower assortment. Simply make certain there’s wholesome stem and leaf development hooked up to every root part.
Planting
This cool-weather flower thrives in spring or fall and doesn’t take pleasure in temperatures over 80°F. Most gardeners plant snapdragons within the spring for an early summer season bloom, however you’ll be able to develop a second spherical within the fall for an autumnal show.
Heat local weather gardeners (zones 7 and hotter) typically plant solely in late fall to take pleasure in additional early spring flowers. They continue to be tender perennials in areas with delicate winters.
How you can Transplant
Transplanting these dragon-tongue flowers may be very simple and just like planting vegetable seedlings. The very best time to transplant is within the early spring, proper after the final frost. Some gardeners plant just a few weeks earlier than the final frost date and canopy snapdragons with row cowl.
Examine that the seedlings are totally rooted of their cell trays and have a number of lush units of true leaves. The vegetation mustn’t have flower buds whereas of their pots. In the event that they do, pinch them off.
Gently therapeutic massage the pot to loosen the roots whilst you maintain the plant at its base. Use your palms, a trowel, or a hori hori knife to organize a planting gap about 1.5 instances bigger than the foundation ball. Place the seedling within the gap, guaranteeing that the soil stage stays the identical. Gently backfill and evenly press in place.
You’ll want to transplant within the morning or night as a result of the noon solar could be too intense for younger seedlings. Water totally on the base and keep constantly moist however not soggy soil.
Spacing
Most snapdragon varieties are spaced 4-12” aside, relying in your desire for lower flowers and whether or not or not you pinched the plant.
For lower flowers: Excessive-density planting (4” sq. for every plant) yields a single harvest of lengthy single stems nice for vases and bouquets. You possibly can widen spacing to 9 x 9” to reap stems over a chronic interval. These production-style planting strategies typically use floricultural netting expanded horizontally over the mattress to assist and assist area out the vegetation.
For decorative: If you’re rising snapdragons as decorative vegetation that can stay in your backyard beds, I like to recommend planting at a wider 10-12” spacing and pinching the vegetation for optimum bushiness and floral development. Analysis from Cornell Horticulture reveals that should you pinch the primary rising tip after six leaves have shaped, it boosts stem yields by 30-50% so long as you select wider spacing. Nonetheless, this can delay your floral manufacturing by 2-3 weeks.
How you can Develop
This easy-to-grow flower doesn’t require way more than well-drained, loamy soil, sunshine, and constant moisture. When you’ve got efficiently grown tomatoes, pansies, petunias, or geraniums, you’ll have no downside with this snappy hooded flower.
Mild
Snapdragons choose full sunshine however tolerate partial shade. Not less than 6 hours of direct daylight per day is required for optimum flowering. Select a location with brilliant southern publicity and few shadows from timber, shrubs, or close by buildings.
Vegetation bloom much less when uncovered to extended shady situations. However in sizzling climates, these cool-loving flowers take pleasure in some afternoon shade respite from the solar.
Water
The moisture preferences of snapdragons are just like many decorative annual flowers: moist however by no means soggy. They don’t seem to be drought-tolerant and wish at the least 1 inch of supplemental watering per week when there isn’t any rain. Water on the base of the plant’s crown moderately than overhead. Overhead irrigation with sprinklers may cause points with fungal illness.
When your vegetation are established, let the highest inch of soil dry earlier than watering once more. All the time stick your finger a number of inches within the soil to examine the moisture stage earlier than irrigating. If you happen to can not really feel the dampness and your pores and skin comes out clear, the soil is probably going too dry. The fibrous roots are pretty shallow and can’t stand up to drought.
Soil
A loamy, compost-rich flower mattress is good for colourful, snappy blooms. This Mediterranean native doesn’t tolerate waterlogged or heavy clay situations. All the time amend your beds with additional compost, vermiculite, perlite, or peat moss to enhance drainage and natural matter. A impartial pH between 6.0 and seven.0 is good.
If rising in containers, select the very best high quality potting mix and keep away from compacting it within the container. The soil doesn’t should be ultra-deep (a minimal of 8” will suffice), nevertheless it should permit water to cross via freely.
If you happen to pour water on a potted snapdragon and it swimming pools up on the floor, it is a signal that the soil must be amended. Water ought to movement simply via the soil profile and out of the underside drainage gap.
Local weather and Temperature
In contrast to vibrant petunias or showy zinnias, snapdragons are cool-weather flowers. They like temperatures between 50° and 70°F. If the climate goes over 80°F, it gained’t kill the plant, however it could trigger flowers to die again. The vegetation typically start blooming once more as soon as the climate cools.
In southern climates, it’s finest to develop snapdragons within the fall, winter, or early spring. In delicate northern climates, you’ll be able to take pleasure in their blooms all through summer season so long as they’ve loads of moisture.
Fertilizing
This isn’t a heavy-feeding plant, nevertheless it enjoys a balanced mix of wealthy compost and slow-release natural fertility. Watch out with nitrogen, as an extreme quantity of nitrogen fertilizer can result in an overgrowth of the spiraling leaves on the expense of flowers.
To benefit from the most flower show, select a fertilizer with a balanced NPK. For instance, Espoma Natural Backyard Tone has an NPK evaluation of 3-4-4, which is ideal for feeding snapdragons on the time of planting.
Upkeep
The one upkeep these flowers require is pinching and deadheading. Pinching is elective, nevertheless it encourages a bushier, extra floriferous plant. In case your seedlings seem leggy or lanky after they attain 4-6” tall, pinch them again to about half their measurement. Elimination of the central rising tip (scientifically known as the apical meristem) tells the plant to focus its development on facet branches, buds, and flowers.
Common deadheading can also be elective, nevertheless it promotes new development and extended blooming. If you need as a lot colour as potential in your beds, take away spent flowers as soon as every week. All you want to do is lower the stem simply above any new pair of leaves. The plant will take this as a queue to develop extra new buds. If the plant turns into leggy through the flowering stage, you’ll be able to optionally pinch (prune) once more by slicing additional down the stem.
Solely the tallest varieties require staking in high-wind areas. The three-foot-tall stalks can bend and break if grown in an unprotected a part of the backyard.
Varieties
Snapdragons are sometimes categorized in one in every of three teams based mostly on the varietal peak:
- Dwarf (8-12” tall)
- Intermediate (12-24” tall)
- Tall (24-36”)
Solely dwarf vegetation ought to be grown in containers. Tall vegetation are nice for the backs of annual flower beds the place you need to create dimension behind lower-growing blooms. A mix of types can even create a pleasant stacked, textural show of various colours and heights. My favourite cultivars embrace:
‘Night time and Day’
This spicy-scented snapdragon is a bumble bee favourite. ‘Night time and Day’ flowers are burgundy and vibrant purple with white jaws. They make beautiful lower flowers and an much more thrilling autumnal show. When the autumn climate cools, the darkish purple petals flip almost black, and the leaves distinction with darkish burgundy hues.
‘Night time and Day’ really blooms night time and day for a chronic show. The flowers are edible, making a fairly garnish on desserts, salads, and cocktails.

The 1” large flowers seem in a rainbow of white, yellow, purple, and pink. They begin blooming on the decrease stalks and transfer upward till the tip of the flower spike opens.
This mix is one other bee magnet. The bees climb into the “mouths” of the placing flowers and pry them open to entry the wonderful nectar and pollen inside. If rising in a sizzling summer season space, present afternoon shade.
‘Magic Carpet Mix’
Excellent for hanging baskets and containers, this dwarf selection is low-growing and petite. It maxes out at about 8” tall and 4” large. The spring-colored mix contains yellow, pink, orange, and white. They create a magic carpet of charming blooms alongside low-growing annuals like alyssums or petunias.
‘Orange Surprise’
For a long-lasting bouquet or vase, ‘Orange Surprise’ is the proper peachy orange and pink snapdragon. The luxurious inexperienced foliage completely contrasts the beautiful pastel ombre colours that fade into deep pink on the backside.
This tall selection grows as much as 3 ft and gives lengthy, elegant stems for the lower flower fanatic. Like all snapdragons, bees and different pollinators love the dazzling 1.5” blooms stuffed with nectar.
Pests and Ailments
Snapdragons are typically fairly resilient, however typically they fall sufferer to sap-sucking pests and ugly ailments. Fortuitously, these points are straightforward to stop with satisfactory spacing and plant care. In the event that they do get out of hand, most issues have a protected natural answer to maintain your flower beds thriving with out artificial chemical substances.
Aphids
These small, soft-bodied bugs could seem in your vegetation any time of yr, inflicting the leaves to distort and curl. They have an inclination to assault harassed vegetation, so preserve your snapdragons well-watered and develop them in loamy, well-drained soil.
If an excessive outbreak happens, a combination of neem oil and water can assist take away the aphids, or use a twig bottle with diluted insecticidal cleaning soap to spray down vegetation. Keep away from spraying the flowers if potential. Whereas neem oil and insecticidal cleaning soap aren’t thought-about dangers to most pollinating bugs, avoiding direct spray into the flowers prevents contaminated pollen that bees may carry again to their hive.
Spider Mites
Spider mites are tiny arachnids that seem like little brown or purple dots on the underside of snapdragon leaves. They’re particularly frequent in container vegetation and choose dry, heat air and harassed vegetation. They’re tremendous straightforward to kill with a blast of water, wiping down the leaves with diluted neem oil, or an software of insecticidal cleaning soap.
Mealybugs
These oval sap-suckers trigger related harm to that of aphids. You’ll discover little white cottony bugs on the stems and leaves, typically with a sooty mould fungus or ants because of the sticky excretion they excrete.
They’re primarily an issue in northern local weather houseplants however could assault out of doors snapdragons in heat climate. In excessive infestations, the snapdragon leaves could flip yellow or disfigured, and the flowers will fall.
Do away with them with insecticidal cleaning soap or neem oil, as described above. You can even use a cotton swab dipped in alcohol to power particular person mealybugs to launch from the plant should you solely see one or two.
Rust
The commonest illness in snapdragons is rust, which could be recognized by the small orangish-red blisters that seem on the undersides of leaves. These sporangia launch powdery spores that unfold the illness farther across the plant, resulting in widespread yellowing and eventual dying.
Rust is a fungal an infection that primarily takes maintain in excessive humidity and dense spacing. After eradicating and disposing of contaminated leaves, apply an natural copper or sulfur-based fungicide. Prune your vegetation to enhance air circulation.
To stop rust, keep away from overhead watering and area vegetation wider aside in humid climates. Some snapdragon cultivars are rust-resistant.
Powdery Mildew
This white powdery substance assaults many vegetation within the backyard, inflicting a pale, powdery coating over the leaves and widespread yellowing or foliage dying. Powdery mildew thrives in damp, cool situations, which regularly coincide with the prime season for snapdragons.
Prevention is vital:
- Area vegetation farther aside
- Enhance air circulation with pruning
- Keep away from overhead watering
- Use drip irrigation or soaker hoses
You possibly can apply neem oil or potassium bicarbonate to deal with contaminated leaves and stop additional unfold.
Damping Off
This fungal illness solely impacts snapdragons within the seedling stage. You’ll discover the newborn vegetation instantly wilt and collapse. They’ll seem girdled or rotten proper on the soil line. Though you can not save dampened-off seedlings, you’ll be able to simply stop this subject sooner or later:
- All the time select a well-drained and sterile potting combine.
- Keep away from overwatering; an excessive amount of water may cause fungal rot within the immature stems.
- Place seed trays in an space with a fan or breeze to make sure correct airflow.
- Keep away from extreme crowding or overseeding. Skinny your vegetation!
