Re: tall small yellow sib seedlings

Marc,

When I tried to divide a piece of the mother clump I couldn't get the
spade to penetrate the clump, even by jumping on the spade. It was like
trying to split a solid tree stump with a shovel. So I came back later
for its seedpods. The following year I went to divide a piece and
noticed another clump not far away that was smaller and slightly shorter
but had nicer flowers. I thought I would remember it by location but the
following spring when I went to dig it I discovered I should have marked
the plant.

There are dozens of volunteer clumps of Siberian irises in this
abandoned garden. I grew SIGNA seed exchange seed there for quite a few
years, many species iris seeds and some seeds from named irises. Only
the Siberian irises have not only flourished but volunteered and are
increasing on their own with no help. There's lots of variation in
height, colors, flower size and forms. Every year I notice more clumps.
