My penstemon, native to poor western soils, was started from seed obtained at last year's seed exchange. A few seeds produced five healthy seedlings. They were planted last spring in the front near the house where sun is plentiful, and near the driveway pavement where soil is warm in summer and consequently dries out fast. Perfect for them, I thought.
One solitary stalk from one plant shot out of the central plant, producing this cluster of blue blooms. Several protrusions on the other four plants looked like they would join the party, but they were just teasing me. Nothing materialized from them. But, oh! that one with its color.
Reading up a bit more, I learned that fertilizing is unnecessary and just produces leaves. Their location has good soil; maybe too good. I don't recall fertilizing them, but did not give them a poor gravel soil, either. One more summer, and I anticipate some excitement next year. I wonder if Rocky Mountain penstemon would make a good addition to my hell strip?
