Everyone grows the Asian butterfly bushes because of their huge flower panicles, but there are some really cool native buddleias that are mostly overlooked. Below is Buddleia marrubifolia from Presidio, Texas. Native to the Chihuahuan Desert, mature plants can reach 6′ tall x 6′ wide. The hairy white foliage serves as a nice foil for the odd, small orange, sattelite-looking flowers that adorn the plant starting in late summer. We last offered this in 2000 to raucous sales–just kidding about the raucous sales. Nurserymen disdainingly refer to these as BIO plants….botanical interest only. Hardiness Zone 7b-10b.
Most folks have grown butterfly bushes in the genus buddleia, yet few garden visitors recognize this fascinating species from our 1994 botanizing trip to Northern Mexico. I should add that most buddleias on the market are developed from the Asian species, and virtually none from the less colorful North American species.
Buddleia cordata ssp. tomentella grows in rocky, bone-dry hillsides in the mountains of Northern Mexico near the town of Los Lirios at 7,000′ elevation. I was only able to find a single seed, but fortunately, it sprouted, and 28 years later, this amazing specimen is the result.
One of the cool things about Buddleia cordata ssp. tomentella is the insanely fragrant flowers, which start for us in early fall, and continue all winter…a trait you won’t find in any other temperate shrub of which we’re aware. As you can imagine, it is awash with an array of pollinator insects The flower color is a dusty white, so this will never be a plant that will make it to the shelves of your favorite box store. That said, it’s a plant we wouldn’t be without in our garden.
We’ve written before about plants that get much larger than we are told in the catalog descriptions. Well, our latest example is Buddleia ‘Sleeping Beauty’, a hybrid of Buddleia lindleyana and Buddleia davidii. In two short years in the garden, it became a monster, reaching a 7′ tall x 12′ wide with no sign of slowing down. It was quite lovely and floriferous, but has now become a welcome member of our compost pile…sigh
