Morning all,

Just been given Montbretia by a neighbour, thinning her patch. I have
the corms, complete with greenery and even a few orange flowers. No
earth on the corms.

When should I plant them? Now, or spring? Should I cut off the growth,
or just leave it to wither and die?

Thanks!

The latter although it's almost impossible to kill them.
BTW I think they are now called Crocisma if you need to look them up,
