Hi drdawg !! These are a mix of cuttings I started sometime in March...I am not sure as to the names ...I have just inquired from the gentleman I purchased them from for the names...Yes I believe down here in Florida that is what the consider Pea stone..Being from Michigan the Pea stone there is very different...Anyway I did a lot of surfing on the net to get my information and saw many people top dress with this..Something about helping with the heat dispersing...I'm new to this ballgame I think when I do it again I will use larger pots instead of 1 gallon...I will probably keep the nice ones and sell the rest...
