Iris Cristata- Blue Form

Submitted by Shepard on Sat, 02/06/2016 - 11:38

I have had this for several years, and it has not bloomed.  I have never had an Iris that didn't bloom.  Any recommendations? 

BTW, I have it in three different locations, all with different sun locations.  I have not had it in shade, or semi-shade.  Soil is quick draining. It has not been fed.

Hello Shepard, i'm guessing that you have your Iris cristata planted in too sunny and quick draining a spot. This is a terrific woodland Iris, it will take lots of sun but does best in half shade at least, or even full shade, planted in humus-rich soil, although with the horizontal rhizomes right at or above the soil surface. The 1st photo here is a cultivar of Iris cristata named 'Edgar Anderson', a robust selection of this fine crested Iris. The 2nd photo shows the surface rhizomes of Iris cristata taken just a week ago on Jan 31st, 2016, before being buried in snow again, but it shows how the rhizomes want to be at the surface and not buried.

I don't know where you are, but I am in Minnesota and if you would still like to have that type of iris in the sunnier/drier locations, I find that Iris lacustris does better than cristata for me.  My clone came from Heronswood long before it was sold, but there are plenty of cristata sold out there posing as lacustris.  If you would like, I can send you a start of it in spring.
