It’s hard to imagine a plant more obscure that the Southeast coastal native Houstonia procumbens. You may recognize the name houstonia as belonging to one of the many more common bluets. Instead, this is a creeping white-et. We’ve had this in our alpine rock garden for a couple of decades, but barely notice it until November, when the flowering picks up as other plants around it are going dormant. In the wild, Houstonia procumbens can be found in moist pine savannahs as well as nearby disturbed habitats. We’re unsure if this is showy enough for anyone to actually purchase.
Most gardeners in mild winter climates are familiar with Liriope (monkey grass), and Ophiopogon (mondo grass), but almost no one is familiar with the third cousin, reineckea (false lilyturf). Like both better known cousins, reineckea is an evergreen groundcover, but unlike the others, here is our clump of Reineckea ‘Little Giant’ in full flower for Thanksgiving. Depending on your taxonomist, there is between 1-3 species in the genus. We’re certain of three and think there may be more. We have assembled a collection of nearly 30 wild collections and will be working with other researchers to sort out the taxonomy of this group.
In full flower this fall is Disanthus cercidifolius. Ok, so full flower on a disanthus may not seem too exciting to the petunia and pansy crowd, but plant geeks find these flowers pretty darn cool. We’d nearly given up on growing this witch hazel relative after finding in our first few attempts that it has zero heat tolerance. It wasn’t until we obtained a plant from a Chinese population (Disanthus cercidifolius ssp. longipes) of the better known Japanese native, that we realized there is a form we can grow, and grow well. Not only does the Chinese form have heat tolerance, but it also thrives in full sun. The specific epithet “cercidifolius” means foliage like a cercis (redbud).
We are just loving our hardy hybrid cycads in the garden this time of year, and here are two we photographed this week. The first is Cycas x bifungensis (bifida x taitungensis), and the second is Cycas x panziholuta (panzhihuanensis x revoluta). We have found that hybrids between hardy species are even more winter hardy than the species themselves. Hardiness for both is probably Zone 7b and south.
How could you not love a plant with the name poet’s laurel? Poet’s laurel has a long history in Greek and Roman culture representing praise for a victory or great achievement in the form of a laurel crown. Danae woven-stem wreaths were also bestowed upon revered members of society who, if they then lived off of their past glories, were said to be “resting on their laurels.”
The laurel referred to, is Danae racemosa, a classic pass-along plant in Southeast gardens, although it originally hails from half-way around the world…Iran and into the nearby Caucus Mountains. In the florist trade, where it’s highly prized, it’s often referred to as Italian laurel.
The evergreen Danae racemosa is hardy from Zone 7a and south, and fruits best in very open shade to a couple of hours of morning sun.
In the “in case you missed it”, this clever gag gift for the plant lover in your life has appeared on-line just in time for the holidays. Not sure what else we can say, other than watch for fire ants and chiggers.
We love the appearance of plants like agapanthus in the fall, long past the season when the showy blue flowers graced the top of each now browning stalk. In fall, it’s more like looking out on a mass of punk rock hairdos. These garden features are so much more interesting than flat beds of mulch, created far too early by garden neat freaks. This is the cultivar Agapanthus ‘Prolific Blue’ which puts on a superb fall/winter show.
With over 60% of retail plants now purchased at the box stores, we wonder if most consumers know you can’t trust much if anything you read on a label at a mass marketer. Our most recent example is this tag on an Illicium parviflorum at our local Lowes. I particularly love the common name, Japanese Anise. Unfortunately, Illicium parviflorum is native only to Florida…quite a few miles from Japan.
The tag mentions full sun, which Illicium parviflorum certainly tolerates, but in the wild, it grows naturally in moist woodlands.
Then, there is the note about cool temperatures and warm soil promotes root growth. Well, warm soil does promote root growth for some plants, but not for all. Wouldn’t the soil have been warmer in mid-summer than now? Just wondering…
And, if that wasn’t enough, our staff taxonomist, Zac Hill spotted this tag for our native bald cypress, Taxodium distichum at a different Lowes store. The problem is that the plant is actually a Chinese Dawn Redwood, Metasequoia instead of a Taxodium. I wonder if they thought…”what the hell, those dumb consumers will never know the difference.”. After all, it’s just another little green lie. As Anita likes to say, ‘The way you do one thing is the way you do everything.”
The splendid, giant-growing Salvia madrensis ‘Redneck Girl’ is a JLBG introduction and has been at peak the last few weeks. This is so superb for climates where you can avoid an early fall frost.
Although we’re celebrating Thanksgiving, Geranium ‘Azure Rush’ is still flowering as though it was mid-spring.
