This lovely aromatic Plectranthus is an easy, non-stop flowering perennial here in San Francisco. It is not at all cold tolerate and will turn to black mush anywhere near 32 degrees F. Most places it must be considered an annual. What makes this plant so spectacular here is it's ability to root anywhere, any time of the year. I toss my clippings where ever I want it to root and establish and it does! I got mine at Plectranthus neochilus at Annie's Annuals.
Here it is with Verbena and Nigella.
