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.
With the trend for green mulch (i.e. groundcovers), we continue to trial a number of new introductions that fit the bill. One of the top performers continues to be Sedum ellacombeanum ‘Cutting Edge’ PP 28,926. This 2016 Brent Horvath introduction has thrived in both sun and light shade, making a perfect ground-hugging mat. Despite being a top performer, sales were miserable when we offered it a few years ago. We’re not sure why it sold so poorly, but we now have some lovely drifts in the garden.
The dwarf groundcover Sedum tetractinum ‘Little China’ is superb throughout the growing season, but we particularly love when cold weather arrives and the olive green foliage turns to bright red in the sun…what a superb winter show. Hardiness is Zone 4a-8b.
