Description

Manfreda maculosa is a deciduous, succulent perennial that grows nearly flat to the ground, forming a rosette of fleshy, narrow, up to 1 foot (30 cm) long, soft, sword-shaped, dull-green leaves. They are heavily marked with round, reddish-purple to dark brown spots. In the spring appear long spikes, up to 6 feet (1.8 m) tall, bearing mildly fragrant, up to 2 inches (5 cm) across, cream to greenish-white flowers that age to a rose pink. They open and change colors over 3 to 4 days of life.

How to Grow and Care

Manfreda is a tender perennial or "temperennial" succulent plant that grows best in full sun. Plant in well-drained, dry to average soil in containers just slightly wider than the width of the rosette or plant directly in the ground. Since the plant has a rather large root system, the container should be at least 12 inches (30 cm) deep. Manfreda is a slower grower, so it will not quickly overtake the space it is allotted in the landscape.

In summer when the plants are actively growing, they appreciate a bit of supplemental watering and half-strength fertilizer. During the winter months, the plants should be allowed to dry and should be stored in a cold room at 48 °F (9 °C). Plants are watered only enough to keep the foliage from shriveling.

Manfredas are propagated by the removal of offsets and from fresh seed. Fresh seed germinate in 7 to 21 days at 68 to 72 °F (19 to 22 °C)… – See more at: How to Grow and Care for Manfreda
