Penstemon (Penstemon Spectabilis Showy) - Perfect for the naturalized xeriscape landscape or the wild flower garden, this Showy Penstemon plant grows 24 - 40 inches in height. It is a perennial flowering plant grown from flower seeds that features large, violet trumpet-shaped flowers growing on spikes. Showy Penstemon commands attention! It is native in dry creek beds, hill sides and coastal bluffs of southern California as it is quite drought resistant. It blooms in late spring through summer. This species will self-seed.
The flowers attract hummingbirds and butterflies into the garden. The drought tolerant plants will tolerate and even thrive in poor soils, but they require relatively good drainage. It is recommended to directly sow this flower seed outdoors into prepared beds in late fall. In the late fall, loosen the soil and scatter the seed thinly on top allowing spacing so that you can move the plants after they have developed if you need to. Put a very thin layer of coarse sand or potting soil over the flower seeds. They will lie dormant throughout the cold weather of winter, but the moisture and coldness is actually helping the Penstemon seeds, and once spring temperatures come, they will begin to sprout. They will become sturdy plants by mid-spring, and if you need to, the seedlings are easy to transplant to permanent locations at that time in your xeriscape garden. Showy Penstemon care includes little watering once established, avoiding overly fertile soil, and deadheading spent flowers to promote longer blooming.
Approximately 50,000 seeds per ounce.
