Horehound / Marrubium

Marrubium rotundifolium / Silver Edged Horehound
From High Country Gardens in fall 2020
Planted 4 in different locations - three survive


Expectations:
This is a xeric groundcover with fuzzy leaves edged in white. These want sun and dry conditions and will eventually form a mound that spreads out and spills over. Flowers are insignificant and should be cut off when they appear to keep the foliage much nicer looking.


Experiences:
I planted these in various spots but in 2021 moved them to the front triangle to spread out. Each little clump has an irrigation emitter.

The neighbors on Soaring Eagle have a big spread of these groundcovers in their front yard. 

Just planted in the 
front triangle garden

By 2024 they were okay, but not spreading. I think I need to take away the volcanic rocks there to get them more soil to spread into.
