Gardeners' Notes:

I had a toadshade hitchhike with the root ball of some Arundinaria gigantea that I dug up near Chattanooga, TN back in 2005. Since then, it has not only survived in the woods behind my house, but has even thrived, going from a single plant to at least three flowing sized plants and a few additional babies.

These plants definitely do well in shade, since mine is in at least moderate shade all day.

This plant appears in my shade garden with a maroon flower and in my sunny garden with a light green flower. It starts out in zone 6b in Connecticut in early April before most other growth and is interesting in the way it starts growing. It has been in bloom for more than 3 weeks and is still going strong. It seems to be relatively hardy and spreads slowly, and I look forward to seeing it sprout up each spring. It is far prettier and more unusual than the plain trillium.
