This one is a 'Charm-er', get it?We have had this in the nursery since we first bought it. I'm kicking myself for not putting it on the site sooner. It is a knockout! Deep pink in the nursery and rich blue in our acidic soil. Wow! The origin of this one is totally unknown. I've seen it listed under 'Charm Red' at other nurseries. This is a compact plant but large and showy. Plant in a mass or in a container!
