The "regular" Siberians have 28 chromosomes and are derived from I. siberica
& I sanguinea while the Sino-sibs have 40 chromosomes and are the result of
crosses of Ii. clarkei, delavayi, wilsonii, forrestii, chrysographes & the
probable hybrids bulleyana, dykesii & phragmitetorum.
The Sino-sibs are not crosses with PCNs but they will cross with them to
produce sterile but often very nice progeny.
In general, the Sino-sibs are smaller plants in both their foliage and
flowers and with more color patterns. I like the small graceful flowers very
much. They are probably less hardy than the 28s below zone 5 but in zone 5 &
above they are easy to grow and take care of. If planted close by one of the
rampant 28's they can be in danger of being overrun.
I think they are a much overlooked treasure.
