– Impatiens Walleriana – These are the most commonly grown cultivars with short plants, attaining a height of not more than one foot. Some types, like the ‘Super Elfin’ series, are much shorter. The standard impatiens flowers come in various colors that include red, white, pink, purple, violet, coral, and a new color, yellow.
– Impatiens Hawkeri – This type also goes by its common name – New Guinea impatiens. It is notably larger than the standard impatiens and showier in terms of its foliage. New Guineas also love some little sunshine than the Walleriana species. Many gardeners prefer this New Guinea type in containers.
The Best Time To Plant: If you start from seeds, sow them indoors at least 8 to 10 weeks before the last frost date. Set out your transplants in early spring after the soil has warmed up. These flowers are sensitive to low temperatures so ensure the threat of frost has passed.
