Gardeners' Notes:

I have been growing Turtlehead for at least 15 years. A white version shows up occasionally, several inches away from the pink patch. Both colors are reliable bloomers.

In late May, I pinched some of the tallest branches to make them develop two leaders instead of just one, reducing the overall height somewhat.

This year (and last year) it is troubled by powdery mildew. I had not seen that in the past.

My favorite aspect of Turtlehead is watching the large bumblebees crawling into the blossom and disappearing, then backing out just like a car coming out of a garage. Very entertaining. I grow the plant near my patio in a patch of clay-like soil that holds extra moisture.

This is a terrific plant for late summer color. It blends in with the border all summer long with nice clean deep green foliage until late summer when it it is covered in pink blossoms. I have a 5x5 patch that is slowly expanding if I don't beat it back occaisionaly.

A good perennial for late summer colour. Doesn't like excessive heat. A bushy perennial that likes full Sun and a moist soil. Combine with other late summer flowers. pokerboy.

Divide the crowns to reduce large clumps in older plants.

Seeds require stratification(chilling) Refrigerate seeds in mixture of moist peat moss or seed-starting medium in a
plastic bag. Close with a twist-tie and refrigerate for 4-6 weeks. Then sow the mixture as you would normal seed.
