Here’s a garden shot at JLBG, using a good bit of gold foliage in addition to flowers. Left to right: Viburnum dentatum ‘Golden Arrow’, Sinningia ‘Amethyst Tears’, Baptisia ‘White Gold’, Canna ‘Tama Tulipa’, Lysimachia nummularia ‘Aurea’ (groundcover), Hibiscus ‘Holy Grail’ (purple), Spirea thunbergii ‘Ogon’, Trachycarpus fortunei (palms).
We love our Mediterranean blue fan palms…one of the coolest palms we can grow outdoors. We’re right on the edge of winter hardiness for Chamaerops humilis var. argentea, so the key is to grow it to a larger size before planting in the ground. We’ve lost a few that we planted too small, and when that planting coincided with a cold winter.
This is a photo taken this January of our oldest clump, now 17 years old. This is a very slow growing palm, so a good bit of patience is required when getting it established. When we do experience single digits F winter temperatures, all of the foliage is burned back, but it re-sprouts from the base in spring. Mediterranean blue fan palm hails from high elevations in the Atlas Mountains of Morocco, where it eventually makes a 15′ tall specimen. In our cold winter climate, we doubt it will ever top 4′ in height. It should be winter hardy from Zone 7b and warmer.
Due to having three consecutive mild winters, with no temperatures below 20 degrees F, we’ve actually been able to get a trunk on our Washingtonia filifera palm. Typically not hardy in our climate, our plant was grown from seed collected from a wild population in Arizona that had experienced 10 degrees F. We’ll see what this winter has in store.
We love plant mysteries, and Sabal ‘Blackburniana’ fits the bill nicely. This pass-along seed strain has been considered by some to be an old hybrid of Sabal minor, while others consider it to be synonymous with Sabal palmetto, yet others consider it to be Sabal domingensis. Whatever it is, our plant is looking quite good in the garden. After growing it, unscathed, since 2008, we finally decided to propagate some for the upcoming Plant Delights catalog. If you know any more historical background about this curiosity, please share.
No, we’re not talking about your favorite football or basketball team, but the amazing blue Mediterranean fan palm. Here’s our oldest (16 year) specimen in our alpine rock garden this week. Chamaerops humilis is a Southern Europe native that’s marginally hardy in our region, but the blue form, know as var. cerifera (or var. argentea). is much more tolerant of our cold winters. If our winter temperatures drop into the single digits F, the foliage dies back to the ground, but quickly rebounds in spring.
Did you know that North Carolina has twice as many native palms as California?
Join garden volunteer, Mike Papay, on a virtual tour of Juniper Level Botanic Garden as he discusses native and cold hardy palms of the Carolinas as part of our Gardening Unplugged garden chat series, held each day of our Open Nursery & Garden Days.
Evergreen trees and shrubs are the perfect way to spruce up your home during the holiday season. They will hold up for weeks in arrangements and wreaths, anywhere you need a touch of holiday cheer.
Here are some inspirations from the garden. Explore your holiday creativity.
It’s hard to believe that it is already time for our 2019 Fall Open Nursery & Garden Days! My how time flies.
During each day of our Open Nursery & Garden Days, we offer a free garden chat as part of our educational outreach, “Gardening Unplugged”. These are 15 minute discussions walking through the gardens, focusing on seasonally prominent topics, plants and garden design ideas. Join Tony and our expert horticultural staff as we explore all that nature has to offer. Meet at the Welcome Tent near the parking lot to join us!
This Fall topics include:
We are continually on the hunt for new cold hardy palms. When we find an individual clone of hardy palm tree growing in a particularly cold climate, we do what all good plant nurseries do, we propagate it for our plant catalog! There is no reason why gardeners in Tennessee or Virginia cannot have a cold hardy palm tree in their yard just like a Floridian.
Try pairing hardy palms with other tropical looking plants like colocasia, musa, and hedychium. Join Zac Hill, our taxonomist, July 20 at 2 PM as he discusses hardy palms in the garden. This is part of our free garden chat series, Gardening Unplugged, during each Open Nursery & Garden Days.
