Gardeners' Notes:

Great groundcover! Thanks to the tap root, Herniaria stays within reasonable bounds (~2' diameter) and is drought-tolerant once established. I got a 6-pack to stop erosion where the sloping rose bed meets the sidewalk, and loved it so much I've added more around all the garden borders. Beautiful, springy green foliage, heat-tolerant (it's regularly triple-digits and dry here in Fresno). Highly-recommended.

Set it and forget it. It spreads politely, covers unsightly cement breezeblocks set as steps, and stays green all year. Doesn't need mowing. Why aren't we all growing this?
It is a little too polite, and would take forever to cover the whole yard. Or would it????
I have it next to wooly thyme. The line has held fairly firm for 3 years. They are duking it out exceedingly slowly.

I have this growing at the exposed corner edge of my backyard perennial border here in Denver (zone 5b). It has been thriving without supplemental irrigation and has been survived the last 2 winters without difficulty.

This plant not only survived a 3rd winter, but it survived the -20 degrees we had for nearly a week last spring. It even stayed green most of the winter. It has spread nicely around my other plants in the area to cover even more ground and is doing a fantastic job of smothering weeds!

I think the zone chart should be amended to include zone 5b or at least zone 6a (mine is growing in a somewhat sheltered spot).
