What is this?

[Brian Ellis]

Beth Chatto is quite close to the North Sea (only about 5 miles) and, of course a lot more Southerly   Whether this would be enough to enable it to overwinter would be interesting to know.

It is a water Canna. It survives zone 6 winters here. I just reacquired it when I restarted my small pond this spring. Had one for 5 years before letting the pond stagnate for 3 years. Thru the tag away so can't give specifics. Got seed off it one year, now where did I put that

Visited Beth Chatto's garden yesterday and saw this growing in one of the ponds.  Anyone know what it is?

At Beth Chatto are the plants growing in the pound or in a border?

2 acres waiting here for you Paul.

Ah but Lesley, I doubt you're going to give me the place.  It's the money side of things that is the reason I don't have acreage already.

Got a reply from Ian Parker at the Beth Chatto Gardens about the Thalia :
"It has been hardy here for us for about 7 years, including the last two cold winters.
They are planted about 2 feet deep in the water and have no other protection.
Looking fabulous at the moment."

Thanks Maggi, he was certainly right in the last sentence

Wow two feet deep!Quite more than for a Pontederia!Thank you Maggi.
