100+ Rocky Mountain Penstemon wildflower seeds- Penstemon Strictus-B255-Excellent Perennial
Description:
Rocky Mountain Penstemon is a fine source of a brilliant blue color, and it is a native North American plant that gardeners in many parts of the country have come to treasure. The plant has intensely colored blooms that are 1 inch across and shaped somewhat like a snapdragon. They open along sturdy, erect 24 - 36 inch stems giving you enough bloom spikes for cutting and bringing into the house for bouquets. Gardeners are not the only ones who enjoy Penstemon! Hummingbirds and butterflies will be visiting in droves to feed on the nectar.
Rocky Mountain Penstemon seed is considered a wild flower seed. It is recommended to directly sow these seeds 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 to soften the seed coat, 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. Rocky Mountain Penstemon care includes deadheading the spent flowers to promote growth
