Bald Head, but Sexually Active

If you’ve lived in the deep south…the land of palmetto palm trees, you know that they typically don’t flower until they have at least 5 feet of trunk. Of course, flowering can be sped up by a combination of precocious genes and good growing conditions. Those who have studied Sabal palmetto in the wild have noted that the earliest populations to flower are those from the most northern, naturally-occurring population on North Carolina’s Bald Head Island.

Well, sure enough, our oldest specimen of Sabal palmetto ‘Bald Head’, planted in 1999 finally decided to produce flower this summer, and will hopefully seed. We’ve only had enough plants of this cold hardy form to offer through Plant Delights three times in 36 years. Fingers crossed, we’ll be able to make it available more regularly now. Hardiness Zone 7b and warmer.

Struck Gold

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).

Are you a blue fan?

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.

Washington’s Palm ready for winter

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.

Blackburn’s Palm

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.
