is it a purple salvia greggii ? Can you get a picture of it and post it here ?

maybe it's a mesa purple ?

could it be russian sage ? That's a little taller though.

It's shorter than all of those. I'll try and take a picture the next time I'm that direction.

Is it Salvia sylvestris 'Blue Hill' perhaps? I always thought of it as a salvia for cooler climates, but when I saw it growing at ARE I bought several plants and it's done well. It lived through last summer's drought so I bought a few more this spring. So far so good this summer too. It does best where it gets afternoon shade and moderate water.

The office park that I work in has a fabulous display of Henry Duelberg in late spring. The purple is just nearly cobalt blue and blooms for a long time.

Maybe mealy blue sage

ok, here's the pictures!

It definitely looked prettier earlier in the summer, but it still doesn't look bad.

The leaf looks like greggi

I'm pretty sure it's Angelonia, also called 'summer snapdragon'. It's a great plant for Texas' summer. Comes in colors like white, pink, lavender and purple. It's considered an annual, but sometimes winters over. I have several plants in the purple, but next year I'm buying a whole flat of them.

I have pink and purple in containers as they DEFINITELY do not overwinter up here.

Roselee - I think you're right! I actually bought 2 white Angelonia this year and I just went out and looked at it and it does look the same. I guess I associate purple with salvia and never thought about it being something else. Thank you!

That is Angelonia. There are several varieties and they come in white, lavender, purple, pink, and some bi-color. They do look a little like some salvia varities, but they don't have the foliage/stem odor.

looks like Angelonia to me too. Recently read that they have really hardy varieties now. Think I read that in the Dallas paper. Don't know if it said they overwinter but did say that laugh at the heat.

you might look at this. Texas Superstar

I agree with the angelonia identification as well, but there is a newer, more compact series of salvia greggii called the mesa series. This article says that these new varieties stay more compact than other salvia greggii varieties, so if you think that your other salvias are too leggy, you might want to look at these.

Oh! I like the smaller Greggii also. I wonder if it will be easy to find next year.

Angelonia, look at the flowers. Great plant for our heat. I have had it come back for 2-3 years.
