How to Plant and Grow Penstemon
Plant Penstemon Seeds:
Sow penstemon seed in cell packs or flats, press into soil, and barely cover. Kept at 60-70° F., germination in 14 to 30 days.
Penstemons prefer full sun, part sun in hottest climates. Plants need little to moderate water once established. Avoid overly fertile soil. Flowers attract butterflies and hummingbirds. Plants are deer resistant.
