This South African shrub in the same family as Acanthus (oyster plant) is an unsung garden hero! It will grow in dry shade as well as sun, will quickly get to 3metres each way, is easily pruned to size, has lovely rich deep green foliage and a mass of trumpet flowers that are off white with mauve veins in summer after all the spring nonsense is over. Why isn’t it in every garden centre? If it was I would have to stop growing it as heaven forbid that I would grow anything common! It is very slightly frost tender so those in cold areas be warned but it makes it through usually unscathed in my far from tropical garden in Macedon. I have lovely plants at the moment in 8″ pots at $26.50 so get one in your dark dry corner.
