First Flowers of Flat Iris

Late December marks our first flowering of Iris planifolia. This odd native to Southern Europe and Northern Africa has a similar distribution to the better-known Iris unguicularis, but this Iris belongs to the group, known as Juno or bulbous iris. These deciduous iris are extremely sensitive to summer moisture, which is why this resides in

Tongue Caught in the Crack

We’ve struggled for years to grow some of the exceptional forms of Hart’s Tongue fern, Asplenium scolopendrium in our hot, humid climate. One cultivar that we’d long been enamored with is Asplenium ‘Keratoides’. After killing nearly everything we had, we stuck one in the crevice garden, where, to our amazement, it has performed marvelously. It

Don’t Miss the Stones latest show

Putting on a show this week in the garden are the Living Stones. No, not Mick, Keith, and Ronnie, but the horticultural Living Stones, Lithops aucampiae. Our oldest patch starts flowering in early to mid November each year, growing beautifully under an overhanging rock. For all the articles about how difficult they are to grow,

Strumming on a Strumaria

Flowering in the crevice garden in early November is the little-known South African bulb, Strumaria discifera ssp. bulbifera. These hail from the winter wet/dry summer region of the Western Cape, and have been right at home in the ground here since 2018. Okay, so it’s not as flashy as a tulip of daffodil, but to

That Won’t Grow Here

We love it when people tell us that certain plants won’t grow in our climate. As gardening contrarians, we thrive on proving gardening experts wrong. Below is a great example–our combination of Globularia repens (Spain, Italy) and Acantholimon halophilum (Central Turkey) thriving in the dryland crevice garden. Both have sailed through out rainy, humid, hot

Shaz-zauschineria

Through the years, we’ve killed far more than our share of Zauschnerias, California fuchsia, but a combination of building a crevice garden and planting the superb clone, Zauschneria canum var. arizonica ‘Sky Island Orange’, we have a winner. Our clump, which is in full flower in October, has been growing here since 2018. To say

Do you know Polygonella?

We have been playing around with the genus Polygonella since 2000, but have still only grown 3 of the 11 US species so far. We are fascinated why these native, highly drought-tolerant members of the buckwheat (Polygonaceae) family aren’t more widely grown. The common name of jointweed, probably is the biggest factor in their lack

Globs of Globularia

Globularia is a genus of small, rock garden-sized plants in the Plantaginaceae family, with a native distribution centered around Mediterranean Europe. I admired these during our 2012 Balkan expedition, but it wasn’t until we constructed our crevice garden empire, that we really began to have much success with the dryland plants in our wet, humid

Getting a Handle on Handelia

Here’s another of those plants that virtually no one has either grown or even knows about. Handelia trichophylla is a little-known monotypic member of the aster family (Asteraceae). Not only does it have hairy, silver foliage, which usually spells certain death in our summers, but it hails from the “stans”, which include the low rainfall
