I had a hard time getting a White Swan to even live. After about 5 tries
I finally got a couple to establish themselves in an old hog feeding tub
with some Magnus that had been there for a few years. The tub is split
down one side so it drains well. It's in mostly sun but there is some shade
on both ends of the day. Maybe it was the companionship of the Magnus
that got the WS to live. Or maybe just finding the right conditions.
Even my Magnus doesn't multiply a lot. I have it in about 3 places so it
has more opportunities to become invasive if it wanted to.
I'll like to have some of the newer cultivars to see if I can get them going.
Hint, hint. Even seeds.
GOD bless and keep each of you.
