Penstemon

By The Old House Web

Penstemon


These plants prefer a warm sunny position but can take slight shade. They grow in any fertile, well drained soil, but dislike clay. Flowering is best in cool weather.

Propagation is by seed or cuttings. Take softwood cuttings from non-flowering side shoots. The seed germinates in two to three weeks at temperatures between 65 and 75 degrees. Seedling growth will be slow and uneven.
