Are you talking about Penstemon? If so, which species? I would think that J.and P. would list their plants by botanical name.

Pensternon Palmeri: Someone gave me a Fact list re the plant after I put this Q up.

The fact sheet reads like a dream to me. (I like easy plants) Heat tolerant, needs little feeding, reseeds and spreads like a wild flower. Now all the plant has to do is bloom and look like Jackson Perkins' picture.. (smile)

OOPS misspelled it......Penstermon Palmeri

"Must be grown in sandy or gravelly soils, not in tight clay. Not suited to areas receiving more than 15-18" of rainfall annually!"

Just a gentle correction, since you brought it up! PENSTEMON. No R. Congratulations on your purchase!

We get A LOT of rain...I was planning on planting it on a mound...I will add sand to the soil...Gee I hope that works.(sigh)
