Perfect Flower

This was one of my favorite flowers to add to floral arrangements. There is something magical about a white flower, and this variety did not disappoint! Plentiful puffs of white flowers all season long.

Becuse of cold wet weather in Ohio in April and May, I was late getting my seeds planted so I cannot give a review on the performance of your seeds. I can say that I have been very happy with your seeds in previous years and also pleased with your staff. I received the seeds timely and everything I ordered was delivered. Jan Nicodemus
