Penstemon wilcoxii
zones 4-6
50 seeds
Wilcox’s Penstemon is a large plant, but small-flowered variety of penstemon that produces dark blue to blue-lavender flowers. Flower stalks are long and slim, with flowers spaced farther apart than other penstemons, lending a graceful appearance. The leaves are toothed and smooth and clasp around the stem. It’s found growing at higher altitudes in dry, sunny situations.
Seeds should first be sown onto flats. Sink the flat into the ground in an area that offers shade, preferably close to a wall that faces north. Provide a glass or plastic covering. Keep soil moist. Seeds take from 1-6 months to germinate. After 2 years, transplant the seedlings in their final location in autumn.
Alternatively, you may stratify the seeds in a lightly covered pot of moist perlite and vermiculite outdoors in winter, or in a sandwich bag in the refrigerator for 5-6 weeks before planting them in flats or individual pots.
