Gardeners' Notes:

I love this quick-spreading plant and have grown them for years. This year is the first time I have seen flowers! They are only blooming on one of the plants (I planted 6). Why do some flower and some do not? Can I do something to encourage blooms? All the plants receive morning shade and afternoon sun.

Started with one in a potted arrangement. Runners hit the soil. New tubers formed at almost every leaf junction. Frosts and freezes to the soil line in central Florida (zone 8b), but starts growing again when soil warms. Fills in rough areas rapidly in just a couple years. Easy to establish. Grows quickly and may not stay inside garden bounds. More of a runner than a climber.

Very nice consistently dark purple leaves, pretty purple flowers, although they're not carried much above the leaves and each only lasts a day. The only one of the 4 cultivars I have to flower, and today it has 5 or 6 on it. It's in morning and midday sun that's somewhat dappled and seems to love it. I'm going to try to keep the tuber from this one.
