Gardeners' Notes:

Neutral PinetopPlanter On Jul 20, 2009, PinetopPlanter from Auburn Four Corners, PA (Zone 5a) wrote:

The color of this Iris is so subtly beautiful, and so nicely named, I hate to give it a less than positive review, but, as others have mentioned, it is a shy bloomer, and it is rather SHORT in my garden -- not even tall enough to add to a bouquet with other, larger bearded iris. It is still in a relatively small clump after well over 10 years growth, so it doesn't multiply in our area very quickly either.

I think I would try to find a similar color combination in a newer, taller hybrid should I lose Dover Beach in my garden.

Positive violabird On Apr 21, 2005, violabird from Barnesville, GA (Zone 8a) wrote:

I've had this older variety in my garden for at least 15 years showing its hardiness. It is one of my first bloomers in middle Georgia, starting 4-20. I love the softness of this Iris, the light blue and pure white make a striking contrast. Although it's not a profuse bloomer, I look forward to seeing it each year.

Neutral Margiempv On Dec 29, 2004, Margiempv from Oro Valley, AZ (Zone 9a) wrote:

Though I have found this iris to be a good grower - - it does lack substance and won't take the direct sun very well. (At least not in my climate). If one grows it where it gets some afternoon shade - - it does much better.
