The name buckwheat means different things in different places, but in North America it refers to plants in the genus Eriogonum. This is large genus, including mat-forming alpines and shrubs, and everything in between. They come mainly from hot, summer-dry regions, and have silvery-grey, finely hairy leaves, as in common in such habitats. However, it is our relatively warm, wet winters that are not good for some of them. But with cover in an alpine house or greenhouse, or outside with winter protection, the alpine kinds can make most attractive plants. The tiny flowers come in tight little clusters, so look like little coloured buttons. These are often yellow or white, but may also be pink, red or orange, and can vary from plant to plant of the same species, or even with time on the same plants.

Eriogonum cespitosum NNS03-254 is a delightful compact, mat-forming perennial. Many small yellow and rose flowers are borne on leafless stalks in spring, gradually turning red by mid-summer, above attractive silver-grey foliage. Ideal for the rock garden or trough.
