The new impatiens varieties, ‘Beacon’ and ‘Imara’, are described as highly disease-resistant, fast-filling compact bedding plants, flowering from early summer until the first frost. Besides the basic care of regular watering and feeding once a month with a liquid fertiliser, these forgiving plants don’t require any special care.
New Guinea impatiens (Impatiens hawkeri) have ideal compact growth for pots and patio containers but perform equally well in ground. Plant in a goodquality potting mix, with a controlled-release fertiliser. The best position is morning sun and afternoon shade, or good, dappled light. Water pots once a day in midsummer and feed with a liquid fertiliser once a month.
‘Sunpatiens’, another of the new-generation impatiens varieties are interspecific impatiens and are also known as the ‘all-weather impatiens’ – they certainly put on a grand display all season long. With a different growth habit to Impatiens walleriana, they definitely have a place in the garden. They are also forgiving plants (this is the beauty of all impatiens) – if they flop after lack of water, they bounce right back if you give them a drink.
