detailed seed-starting info below

Lovely strongly upright penstemon - a single flower stalk rises from a neat rosette of foliage, with tubular flowers spaced along it. It is supposed to be long-lived - unfortunately, ours all perished after their second season. Maybe the wet conditions throughout the season last year did them in. We're trying again this year (2008).
