Diploid and triploid also means that with more than the usual amount of chromosomes the plant can have more distinctive characteristics...like thick substance, ruffling etc.

Any one have examples,using the name-diploid & tetraploid,

Would,say,H. Tokadoma,for example, be a diploid? or,tetraploid?

Thanks, Carol

Hosta, as a rule, are diploids. Tetraploids have 2x the chromosomes as the typical hosta. You can not be certain of a plant being tet just by looking at it - it must be tested in a lab to know for sure. There are some clues that we can see, though...heavier substance, wider margins. There are getting to be a lot of tet hostas that have sported or been intentionally induced from dip hostas...

Josh never heard of Epiphany? sounds interesting not at the library - got a pic?

Epiphany was discovered by Winterberry Farms. Unfortunately, it was only offered for a single season before they went out of business. I don't have the plant and suspect there are only a few out there.
