Thanks John, I'll look for photos when they are in bloom, I swear I took some! I'll take photos of them as of today later.
I do not spray, and not have fertilized since the plants are so robust and I could find no information on what to use. The only information I have found is that that they may benefit from pruning which I have never done.
I thought these were very low maintenance plants ... maybe not. They are low maintenance if all you want is a flowering landscape shrub.
I'll post pictures by the end of the day .... back to outdoor projects while we have a cool day.
