Toni: Wow, your house and gardens are absolutely BEAUTIFUL!! Love, Love, Love all the color! I'd say it's a very happy house and must be the prettiest in the neighborhood! You have a great eye for color combinations! What I dislike about where we live now ... it's a deed restricted community with so many rules/regulations and all the houses in our little subdivision look exactly alike!
I've learned there are 3 Penstemon's that are native to Florida:
P. multiflora, with white blooms - apparently very popular
P. australis, with light pink blooms
P. laevigatus, said to be rare
My problem will be the fact that all three require dry, sandy soil. We have a problem with drainage here and even one day of rain leaves the yard at this house flooded! At our other house I'd have a perfect spot for them but alas, our tenants aren't into gardening so I don't think I want to plant anything over there just yet. We are talking about selling that house in a couple of years and there will be lots of work to get the yard in shape before selling; I'll probably go with native plants when we get ready to put it on the market.
