Planting & Growing
Whiteout Candytuft will grow to be only 6 inches tall at maturity, with a spread of 15 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 12 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.
This plant does best in full sun to partial shade. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America.
