Hold on, this is really about arisaema...but the topic was raised during my
talk on arisaema at Hosta College over the weekend. I shake my head as I
write this, but you just never know...and now I ask you - do you know?
The question raised to me was this: Is it true that Asian arisaema cannot
live in the same area where native arisaema have been grown? A few people
in the audience were told to plant them a few feet apart, that one would not
survive if the other had already been planted in that area. Yes, I have
grown them side by side without problem although I can't say that I have
grown one in the exact same planting space that was previously holding the
other. The comment was made the one will "kill" the other.
Gene Bush put a light on the subject by saying that maybe the problem really
related to arisaema rust problems; to protect the Asian species from the
rust-prone native species and to plant them distances apart. Aha! Good
answer! That makes sense.
Any other thoughts on this one?
