I love the way they rise up above the foliage and look like blooms on sticks. Purple Sensation is hardy here so I'll bet it will be hardy there too. I have tried others and they only come back sporadically for one or two years and then no more. Here is another bulb I grow in the iris bed but it blooms later.
It is called Nectaroscordum and grows five feet tall. It forms a round ball at the top of the bloom stalk that can grow as big as a soft ball with a paper like covering, then it breaks open and the little bell like flowers fall out. The foliage at the bottom of the stalk is not very tall and different from any other bulb I grow.
