Re: small SIB seedling

 

The ancestry would be sibirica and sanguinea. Yellow forms don't occur in these species naturally, and are the result of years of work on the part of hybridizers. Only the 28-chromosome siberians (those two and typhifolia) and their hybrids are likely to be hardy in your zone; the 40-chromosome species (bulleyana, delavayi, chrysographes, clarkei,Âforrestii, wilsonii) are probably Zone 5 at best.

That is a nice flower. I really like the tall, small flowered siberians. Do you have a picture of the whole clump?

In the mostly volunteer uncultivated Siberian irises at my old garden
there's a good sized clump, the tallest clump (52in/132cm), but with the
smallest flowers. The flower buds are gold/yellow. They opens to white
with some yellow. There are a few flowers that have 4 falls and standards.

This seedling probably came from Signa exchange seed 10 or more years
ago. When I look up yellow flowers in the SIGNA database it only lists
I. wilsonii and I. forrestii as having yellow flowers. None of the
photos for these two species look similar to this small flower.

Any ideas what Siberian species iris this comes from?
