Re: most popular irids

 

Sisyrinchium actually does this naturally. The basic chromosome number is 2n=16, found in, for example, the southeastern S. nashii. A large number of species seem to be tetraploid (2n=32), but the most widespread (S.Âangustifolium, S.Âmontanum) are dodecaploid (2n=96)! I don't think they're noticably larger plants or larger flowers, but given the wider distribution I'd guess it does make them more vigorous. Flora of North America lists the chromosome numbers for most.

I wonder if anyone's ever tried doing the chromosome-doubling trick on our native Sisyrinchium?
(And if they did, what would be the result?)

Good question. But, I have no idea. Where I live irids are not popular... which is why I've neglected them on the website (I can't write about what I don't know about). So if Watsonia & Romulea should replace something else on my list, please teach me!

What about Watsonia, Romulea?
