Species Cross Iris Cal-Sib

Cal-Sib

This is a wonderful cross between the series of Pacific Coast iris (Californicae) and the 40-chromosome Siberian Iris. PCIs notoriously do not like to grow outside of their native range and are temperamental about getting transplanted. Sino-Siberian iris are finicky as well, only thriving in specific conditions. The specific goal of this cross is to get the unique flower characteristics of the PCIs onto a plant that will transplant well. The result is a complete success, at least in our garden. The range within which Cal-Sibs will be successful is still unknown, but I suspect it is much greater than either the PCI or Sino-Siberian.

We grow these in general garden conditions. Basically we plant them green side up, water occassionally, and fertilize if we happen to think about it. They thrive on a bit of neglect and reward us with amazing clumps of beautiful flowers.

We think Cal-Sibs are a premium plant for any perennial garden. Easy to grow with beautiful flowers, and foliage that gives structure to the garden for the entire growing season.

Give them a try. We think you will not regret it.

They do require acidic to neutral soil. Alkaline soil will kill them.
Hardy to zone 6, perhaps colder.
Full sun to bright shade.

SPEC-X Crimson Accent

(Witt, 1998) (20", Cal-Sib)

How to describe? White with a faint tint of lavender, lavender veins and a gold signal. But where this iris really shines is in the crimson red spathes. Exceptionally attractive in the moments just before the bud finally opens! Email me to find out about its unique genetics.
