False Red Agave

Looking great in the garden now is the false red agave, Beschorneria. Beschorneria is a small, little-known genus of only 8 species of plants in the Asparagaceae family–first cousin to the better known genus, Agave. Beschornerias are native from Northern Mexico, south to Honduras. Through the years, we’ve grown 7 of the 8 species, having not bothered to try B. wrightii, due to it’s tropical origin.

The only species that has proven reliable and evergreen here is Beschorneria septentrionalis–a species introduced by the former Yucca Do Nursery from their collections in Northern Mexico.

Several years ago, we were given seed of hybrids of B. septentrionalis x B. yuccoides ssp. dekosteriana. Most of the hybrid plants died because they inherited too many genes from the more tender B. yuccoides, but two plants still remain. Below is one we named Beschorneria ‘Fire Towers’, which appears close to B. septentrionalis in appearance, but perhaps with a bit more vigor.

Palmer’s Winter-blooming Sedum

Sedum palmeri ‘Mendoza’ is looking superb in the garden in late winter. This northern Mexico native is one of our favorite species, flowering far earlier in the year than any of the other sedum species we grow. We had tried Sedum palmeri prior to to growing this clone, and never succeeded in getting it to survive our winters.

In 2002, we were eating lunch at a ski lodge near the border with Argentina and Chile, when I spotted this compact form growing in a flower bed. We have no idea how a plant from Northern Mexico got so far from its’ home, but we’re glad it did. This patch in the garden was grown from a single cutting we legally brought home from the trip. We subsequently named this after the nearby town of Mendoza, and introduced it through Plant Delights in 2013. Zone 7b-10b, at least.

Marveling at Silver Surfer

We were thrilled how well Agave x protamericana ‘Silver Surfer’ came through the 11 degree F. cold snap this winter. This 2007 Plant Delights/JLBG agave introduction was our selection from a Yucca Do Nursery seed collection in Northern Mexico of a naturally occurring hybrid between Agave americana and Agave asperrima.

South of the Border Beauty

Flowering today is the deliciously fragrant Mahonia gracilis, a little-known species from the mountains of northern Mexico. Maturing at 8′ tall x 12′ wide, this evergreen species burst into full flower usually in late January/early February. The flowers buds have great resistance to cold snaps after they open, and the overpoweringly sweet fragrance is legendary. Virtually all of the mahonias in commerce in the Southeast US are from China, so this is quite different from those. In 30 years of growing these, we have never seen a single garden seedling. Hardiness is Zone 7b-9a, at least.

The Un-Buddleia

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.
