Hi,! 5a here, and my most reliable are Earl of Essex, Total Recall, and Best Bet. All TBs. Immortality is a white TB that is supossedly the "reblooming wonder."All of the SBDs that rebloomed for me (or tried) were Baby Blessed , Flower Shower Forever Blue and Purple Joy. I would recomend that you Visit Winterberry Gardens website,and order one of their catalogs. Chock full of culture tips, ideas, and suggestions for "zone". They are a good source, also, and very nice to deal with.They specialize in rebloomers......Arlyn
