Gardeners' Notes:


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.

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.

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.
