Penstemon (Penstemon Hartwegii Scarlet Queen) - If you enjoy attracting beneficial insects to your landscape, start Penstemon seeds and enjoy this long-blooming Scarlet Queen. Hummingbirds also will enjoy the brilliant scarlet tubular flowers with white throats. From June to September, this Scarlet Beardtongue, will reward you with non-stop blooming. Penstemon flower care includes deadheading the spent blooms to help promote the continued blooming. Also, during periods of no rainfall, deeply soak the roots of the plant every 2 - 3 weeks.

Scarlet Queen will tolerate and even thrive in poor soils, but it is susceptible to disease when the soil does not drain well. For cool climates, position Scarlet Beard Tongue plants in full sun, but in the hotter climates some partial shade is good. In areas of frost free, mild winters, Beard Tongue will grow as a perennial and as an annual in other zones.

Growing Penstemon from flower seeds: These seeds do not need a cold treatment to improve germination as some species require. The Penstemon seed can be started indoors in starter trays or small pots in late winter. The flower seeds can be pressed into the soil but not covered. Keep the flower seeds moist. Before transplanting once frost have passed, harden off the seedlings for 10 days or more. At the time of transplanting, pinching back the plant will promote a bushier grow habit.
