You can sow the seeds, but it will probably regrow from its tuber

the tuber and seeds need very well-drained soil, warm and sunny

when dormant and dry.

Dry ... that's what I worried about a bit. It's in the ground in my
veranda^^conservatory and it doesn't look really dry there. Though no
water comes direct on that patch, it must take water from outside,
which is at the same level of a raised bed. It is well drained, so
hoping I'm in luck. I didn't want to remove it and store it. It
looked
so established.

I grew it (from seed) for some years, but it got a root rot of some
sort and effectively died.

Here's the seeds I have. I would be so happy to send you some. I have
the Rothschildiana. Blue skies today and freezing. Perfect really ;o)
