Spacecoast Starburst is not what I was hoping for so far (we have had it 3 yrs). It does okay in our zone 5 garden. Slow to increase and not a lot of blooms. Beautiful flower though. One I will probably move out if I need room. It did bloom during our drought last year which for us was a bonus (many didn't). Waiting to see how it does this year before any decision is made. I am hoping it is just one of those that takes a long time to mature.
