Of all the interesting new plants showing up these days, one family of plants has really caught on. The ‘Solar Series’ of heat and sun tolerant coleus are really quite remarkable.

Coleus provides wonderful stand alone colour, as well as accents for everything else in your garden. The huge advantage of foliage plants, like coleus, is the instant effect they create. When you set out annuals, there’s always that downtime while the plants settle in, start to grow and then flower. With foliage plants, the impact is instant! The other nice thing about foliage plants is the new and wonderful colour combinations you can create, adding a whole new ‘wardrobe’ to your outdoor décor.

Over the past year, we’ve tried a few varieties of sun tolerant coleus in our gardens, and I have to say, we’re thrilled with the results. We’ve also learned how to use coleus in hanging baskets for an instant and longlasting effect. You’ll be amazed at just how great they look.

Moving into the shade just a bit, another coleus innovation is making quite an impression this year. Talk about big – how about ‘Kong’! This variety is absolutely huge, growing to approximately 24 inches tall and wide with enormous leaves in five beautiful colour patterns. ‘Kong’ is stunning by itself but looks fabulous in mass plantings because of its big but compact form. It will tolerate some morning sun, but performs best in full shade and by the way, it is delightful in containers. Developed by Sakata Seeds in Japan, ‘Kong’ has taken North America by storm, and with the warm summer weather, it’s an ideal time to plant them now. They love the heat, and you’ll love the ‘wow’ new look they will provide in your garden.

Coleus blend well with so many other plants and now with the wide range of separate coloured leaves, you can go wild. The black-burgundy and chartreuse varieties are the most widely adaptable. Try black with soft pink and chartreuse with blue. The large array of new colours (over 40) will provide you with many interesting combinations to fire your imagination.

In all our combination plantings with coleus, we let the coleus foliage dominate and accent with a touch of flowers. Too much competition between the two is unattractive and busy looking. You’ll have to experiment, but I can assure you that these plants have a lot to offer.

Most varieties are basal branching, so a little pinching is needed to get a full and bushy plant. Left alone, they will reach two to three feet in height, but with some pruning you can keep them to about eighteen inches.

Coleus are not heavy feeders, but once established, some slow-release 14-14-14 fertilizer would be ideal. Water them well, but let them dry out between waterings. They are drought tolerant, however, in full sun they will need some moisture.
