I ended up buying 12 plants and nine cultivars -- Versa® 'Burgundy to Green', 'Strawberry Drop', 'Tilt A Whirl', 'Buttercream', 'Trailing Purple Heart', 'Dark Star', 'Chocolate Mint', 'Religious Radish' and 'Shocking Pink'. They were all extremely healthy, well-branched plants that I knew would last well into October. Coleus also overwinter easily indoors, so I can get more than three months out of these plants.
I'll share closeup photos of the new coleus once they recovered from transplanting, but here's one of my favorites -- 'Strawberry Drop' -- a trailing variety that I planted at the edge of the garden wall.
If your garden needs a splash of color at the end of the summer, give Coleus a try.
