Penstemon (Penstemon Grandiflorus Large Beardtongue) - Also known as Shell-leaf Penstemon or Large Beardtongue, this Penstemon grows best in full sun, dry conditions, and in poor soil containing rocky material or sand. Shell Leaf Penstemon or large flowered Beardtongue readily establishes from flower seeds. This pink variety is one of the showiest, and the extra large pink to lavender colored 2 inch blooms are often visited by bumble bees and hummingbirds. Often listed as rare species or as endangered in the wild, this beautiful plant is a treasure to grow for your xeriscape flower garden from flower seeds as it is resistant to drought.
Shell Leaf Penstemon seeds are considered to be wild flower seeds. 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 break the seed coat, and once spring temperatures come, they will begin to sprout. They will become sturdy, drought resistant plants by mid-spring, and if you need to, the seedlings are easy to transplant to permanent locations at that time.
Approximately 34,000 seeds per ounce.
