When is a Mimosa not a Mimosa?

What would you say if I told you that virtually everything you know as a mimosa, isn’t? In fact, the commonly known mimosa is actually an albizzia. Albizzia julibrissin, native from Japan through to the Transcaucuses, was brought to the US back in the 1700s as an ornamental. Back in the day, it was actually thought to belong to the genus Mimosa, but this error was corrected by 1806, but as you can see, old names die hard. Although beautiful, albizzia is a prolific seeder, so is rarely planted any longer.

Interestingly, virtually no one grows any of the 25 North American native species of true Mimosa. Below is our plant of Patrick’s collection of the Southwest US native, Mimosa dysocarpa in flower now. This 3-6′ tall, highly thorny shrub, grows natively from 3,500′ – 6,500′ in the dry deserts of Texas, Arizona, and New Mexico. So far, it seems to be liking its new home in NC. It’s a particularly good food for bees, butterflies/moths, and birds, while the fruit is adored by quails.

Playing with Colors, Textures, and Form

Here’s an example from JLBG, of how plant colors, textures, and forms can be used to create a garden vignette. The foreground is Tradescantia pallida (purple), Berberis thunbergii ‘Sunjoy Gold Beret’, Colocasia ‘Coal Miner’, Pennisetum orientale ‘Tall Tails’, and Albizia julibrissin ‘Chocolate Fountain’. The frame is backed with Vitex agnus-castus ‘Sensational’.

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 countries of Afghanistan, Kazakhstan, Kirgizstan, Pakistan, Tadzhikistan, Turkmenistan, Uzbekistan, and Xinjiang. Our particular plant is from a seed collection in Tadzhikistan.

We would not typically expect anything native to the “stans” to survive in the hot, humid Southeastern US, but this is why we experiment, and why we create unique habitats and microclimates in our garden. In this case, Handelia has thrived for four years in our crevice garden, where it grows in a soil mix of 50% Permatill.
