Gardeners' Notes:

It is a pollinator magnet. If you garden for wildlife it is a great addition. Butterflies, bees and hummingbirds love this wildflower.

It is native to AL, FL, GA, IL, KY, LA, MS, SC, and TN. So, it grows in many other zones besides 9a and 9b.

The flowers on my Snow Squarestem (Melanthera nivea) are white to pink.

The bees LOVE this plant, and that is the reason we got the plant as we have seen a diminished number of bees in the area.

The plant was doing great for over a year. About June 09 the stems got black and the flowers and leaves dried and shrivelled up.

We cut the plant way back to save it. We then sprayed it with a copper treatment.

It is now beginning of August 09 and the plant is doing great and about 12" high.

We really hope that this plant will continue to flourish, and I have a note in to the nursery to find out what was wrong with it, so we can prevent it from happening again.

Very fast & vigorus growing "weed" that attracts butterflies. It's square stalk branches have a tendency to droop with the weight of the large water laden leaves. Flowers to about 1" diameter white/off white with black specks. In Florida it's called "Salt & Pepper".
The plant is a Florida native.
