Gardeners' Notes:

Ruby Grass, Bristle-leaved Redtop 'Pink Crystals' has been a wonderful addition to my landscape. It provides interest all year long. I have only had 6 plants come up from seed and am obviously fortunate according to the other comments. One baby plant is growing in a small crack between the street asphalt and the curb. I need to remove it before it becomes too large.

This year, during the extreme heat in August, the blooms were white for a while instead of ruby-colored. When the temperatures cooled some, the wonderful regular color of the blooms returned. This did not happen last year when the temperatures were even hotter so I do not know why this occurred. It could have been because I fertilized the plants.

It's really a beautiful grass; have divided it w/ only some success and have noticed some reseeding.

I love this beautiful grass, however, a year after planting, I have REMOVED every one of the Ruby Crystal plants. I have to call them invasive, as I do not provide supplemental water, and even with our Texas drought, they continued to spread. It's a shame, because they are a beautiful plant, but they kept coming up EVERYWHERE. I don't want them escaping into the hinterlands. My fellow Comal Master Gardeners have also been warned; they are invasive.
