Coleus are enjoying a spectacular - and well deserved - revival. And while Dibleys in the UK and Glasshouse Works in the USA have kept the old favorites available for many years, amazing new varieties of coleus in even more colors and color combinations, from seed and from cuttings, are now being introduced at an astonishing rate. There are even coleus for hanging baskets.
A fine new book on coleus appeared about five years ago (forty years after the previous one), three years ago almost a hundred were trialed outside by the Royal Horticultural Society and so coleus are now again getting the recognition they deserve. Those startling colors just keep tempting us and they look so good with some many other foliage plants and flowers.
In North America coleus (and of course their botanical name is Solenostemon) have remained popular as outdoor summer foliage plants for borders and containers. In Britain, they were relegated to conservatories and greenhouses because of the strange belief that they didn’t perform well outside. But I remember back in the 1980s – yes, yes, I know – that one of the star plants of the summer plantings along the Broad Walk at the Royal Botanic Gardens at Kew was coleus. Two old varieties in particular, ‘Sunset’ and 'Picturatus', were often used to edge the beds.
As I write Glasshouse Works in the US are listing 132 different coleus, Dibleys are listing twenty four coleus, fifty three coleus are promoted by the Proven Winners brand in the US but in the UK Proven Winners don’t feature any at all. But in just two years Terra Nova Nurseries (famous for the vast number of heucheras they’ve developed over the years) has introduced thirty seven new coleus in seven different series - in just two years! And their 2016 introductions have not yet been announced.
Terra Nova have spent eight years developing coleus and their introductions vary from tight and compact to big and bushy with two series (Color Clouds, below, and Color Carpet) intended for ground cover and hanging baskets. You can check out their series and all the individual coleus varieties at the Terra Nova home gardeners website.
At the moment, on both sides of the Atlantic, you’re probably most likely to see seed-raised varieties such as the monster-leaved Kong Series and ‘Chocolate Mint’ (above). But look out for these new series from Terra Nova and give them a try.
