Planted several of these last Summer (2008) as given from a neighbor. Two of them came back this Spring, one of which is doing extremely well in the moist soil under the eaves on the northeast side of the house. My blooms aren't nearly as big as those in the pictures, here, though.

Pefect little spring plant--early and cheerful; but tough enough to hold up to brutally hot and humid houston summers. Prefers poorly drained areas in my garden.

i wouldn't be without this plant but i sowed seeds all over my yard 2 yrs. ago and last spring i pulled up hundreds of plants. so it can be invasive, at least in the blacklands.

Reportedly grows well in most areas of Texas though is particularly at home in the S.E. corner of state where it grows naturally. Also known to do well in Louisiana and Arkansas. Makes a fine airy early-midspring display of lavender-purple-wine (color pH sensitive?) planted in 1' spacing (1st year of bloom). Divide every 2 years. Elegant yet tough and trouble-free. Reseeds readily though easy to control. Perfect plant for that moist-soggy spot and as a naturalizer. Blooms at same time in my garden as breadseed poppy, daylily (early types), Salvia E. Friesland, j. jump-ups, coreopsis and various roses. Underused.

The Brazos Penstemon is a lovely perennial with pretty lavender flowers that bloom in the Spring together with primroses,oxeye daisy, and blue bonnet. The stems are tall so they can be seen above the others and they make a beautiful picture in the wild flower garden. I highly recommend them, I have had them for 3 years now and they are more beautiful every year.
