This is the first summer I have grown this plant, so we'll see how well it performs in my garden. It is reputed to be much less fussy than the other members of the gentian family. It is a late bloomer, and it stays in bloom for several weeks. The flower is a lovely, true medium blue. The flower resembles that of the bottle gentian at first but it does open somewhat. Bumblebees will fight their way inside these flowers to reach the pollen.
