Stachys monieri ‘Hummelo’, Alpine Betony
This is a work horse plant- started blooming a few weeks ago and has kept upright and attractive through a bunch of hot, humid, rainy summer days that made me want to flop and fade.
Just wrapping up its bloom now. Maybe you’ve seen it shine on the High Line in NYC? Trust Piet Oudolf to find plants that make it easier for gardens to look great.
