Heucheras, commonly known as “Coral Bells”, are a shade loving plant which make excellent ground cover and work well in winter pots. Mainly a foliage plant, their leaves come in a wonderful range of colours, from the dark to light purples, reds, vivid greens and silver veined types – something to suit any display.
They do best in dappled shade, preferring moist soil but can be grown in sunny spots as long as the watering is sufficient in the hotter months, and you add regular tomato feed. Heucheras prefer well-drained soil, so in our heavy clay in this part of Kent, dig in some horticultural grit to assist this or grow in a pot. It’s a good idea to add a thick layer of grit around pot grown heucheras as it not only helps with water retention but prevents vine weevils from laying their eggs.
Tidy up some of the foliage in autumn and if they are ground planted, mulch with leaf mould or organic compost, which will prevent “frost heaving” where the root ball is pushed up proud by the ice. This is also a good time to lift and divide any large plants which will rejuvenate them for next year and give you some new plants to propagate.
