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.
