An update on my plant...

My Ipomoea carnea fistulosa is about 7 years old now and is doing well. It has formed a thick base above the soil, with several main stems. The photo shows this seasons growth. There are dozens of buds maturing, so I expect a grand show of blooms again this year. Each winter, I prune the plant to about 12" above the root base. We are in a frost free zone, so regrowth begins late winter/early spring. This plant seems to love the heat. We've had a fairly mild summer this year, with nightly lows in the high 50's, so I suspect that has slowed the green growth a bit. I have been surprised by it's tolerance for drought. It is possible there is an extension of the root mass under the soil, which may explain how it has gone 2-3 weeks without water. The leaves wilt midday, but perk up by morning as I guess is a characteristic of many MG's.

I think it's time I give this plant a little more attention for all it has rewarded me over the years. If anyone knows about the root system of this plant, I am curious?!
