I also got some at reduced price last spring at Lowes. Mine get full sun and I have two of them planted along the outside of my pool screen. They bloomed through the spring but I don't recall seeing flowers during the heat of the summer but they really grew during this time. They are flowering now and really look nice between my mixed bed of Cosmos, Salvias, and then the taller version of Spires (indago or mystic)on the other side. I had never seen butterflies on them until the other day when a Gulf Frit landed on the flower. Nice plus for me! They are probably 3' tall and the two spread out about 3' wide.

I am going it too and have had it about 8 to 10 years. A good reliable plant. :o)

Yes, they are suppose to attract butterflys too!

I bought one at Wallyworld about a month ago.
It now resides in my garden next to the birdbath.
And yes!...I must have more!
They look better en masse.

I have a couple in the ground for 7 or 8 years. Blooms all year long. Good plant.

Well, anybody have a Latin name on this one?

It's pseuderanthemum laxiflorum. I've seen it in my local Lowe's. Glad to see your positive comments about it. - June

I don't grow it but I'm going to now! I like anything with a purple flower and especially one that attracts butterflies. Beautiful plant.
