Gulf Coast Pentstemon is a perennial herb of the Plantaginaceae Family (plantain family), mostly native to North America. Also called Beardtongue, they thrive in a well-drained soil and are good plants for a flower border. This Pentstemon produces flowers in the early spring, on 1-2 foot slender stems, at the same time the irises bloom. My pentstemon is planted along the upper edge of a retaining wall. It is at eye level so it's fragile pastel pink/lavender flowers won’t go unnoticed by anyone strolling through the garden. It throws seeds into the walkway and these propagate readily but are not invasive.


Flowers
partly tube-shaped, and two-lipped  The most distinctive feature of the genus is the prominent staminode, an infertile stamen. The staminode takes a variety of forms in the different species; while typically a long straight filament extending to the mouth of the corolla, some are longer and extremely hairy, giving the general appearance of an open mouth with a fuzzy tongue protruding and inspiring the common name beardtongue



I have Gulf coast penstemon in pink and purple shades and just love it. Mine have finished blooming and have formed seed pods. 






















Dark Towers Penstemon, Penstemon 'Dark Towers' Plant Patent #20,013.  is an unpretentious perennial with crimson foliage and adds depth and interest to a border garden. I believe the plant's seed are sterile, that is where a cutting would be neccessary for propagation, but since it is patented I would not propagate the plant without permission.

 I like penstemon because they survive year after year through wet and dry weather. My original Gulf coast penstemon was purchased from Redenta's years ago. 


The pods have a tear drop shape. These pods are still green in the photo below but they have started to turn brown and dry out.
