We love our Mediterranean blue fan palms…one of many coolest palms we are able to develop outside. We’re proper on the sting of winter hardiness for Chamaerops humilis var. argentea, so the secret is to develop it to a bigger dimension earlier than planting within the floor. We’ve misplaced just a few that we planted too small, and when that planting coincided with a chilly winter.
This can be a picture taken this January of our oldest clump, now 17 years outdated. This can be a very gradual rising palm, so little bit of persistence is required when getting it established. Once we do expertise single digits F winter temperatures, the entire foliage is burned again, but it surely re-sprouts from the bottom in spring. Mediterranean blue fan palm hails from excessive elevations within the Atlas Mountains of Morocco, the place it will definitely makes a 15′ tall specimen. In our chilly winter local weather, we doubt it can ever high 4′ in peak. It must be winter hardy from Zone 7b and hotter.
