Planted Fall 2012, Bloomed both Spring 2013 and now blooming Spring 2014. They seem to do fine here with no pre-refrigeration and are slowly increasing. Some have offspring. Some of my other Hyacinth have been in the ground for 3 years now and are all preparing to bloom as well. I am not sure what will happen if we ever have an extra mild winte rhere but I feel like their beauty is worth the risk.
