Gardeners' Notes:

Neutral swimray On May 8, 2010, swimray from Alexandria, VA wrote:

The flowers are a bit larger than most bearded iris, however, the flower stalks tend to fall over and must be staked.

Overall, like it. The stalks seem to be quite short so I would put it in the front. Said to be a reliable rebloomer, but haven't had it long enough for a rebloom. Invitation put up 4 stalks.
