Solenostemon scutellarioides 'Religious Radish' (Coleus, Flame nettle, Painted nettle)

As basic as a black dress, 15-inch-tall ‘Red Trailing Queen’ bedecks herself from leaf to stem in regal burgundy. Her simple oval leaf shape and straightforward color complement most shades, except blue and true purple. The subtle strength of the coleus’s burgundy foliage strikes a balance with soft pinks or pale yellows as well as bright fuchsias or bold oranges.

‘Meandering Linda’, a close cousin of  Solenostemon ‘Red Trailing Queen’, grows 16 inches tall and bears crinkly, chocolate-purple leaves banded in rich raspberry-pink, with touches of cream along the edges. It makes a scrumptious duo with anything silver, especially the elegant silver-white foliage of dusty miller (Centaurea cineraria ‘Colchester White’, Zones 7–11). ‘Meandering Linda’ appears to be a sport of ‘Red Trailing Queen’, and if planted in less than half-day sun, it sometimes reverts to its plain burgundy form.

The 14-inch-tall cultivar ‘Trailing Bleeding Heart’ has hot fuchsia-pink leaves ringed with purple and a band of lime green.

‘Trailing Salamander’, which grows 14 inches tall, has oval, near-black leaves edged in bright lime. Its neutral color scheme makes it a choice filler for containers. It looks good with almost anything. Coleus are tender tropicals that are generally grown as annuals because they are hardy only in Zone 11. They are easy to grow, reliable plants. Blue to white nettle-like flowers bloom in racemes in summer, but are not showy and tend to visually detract from the attractiveness of the plants.
