prefers to be grown on the dry side once established, will rot in poorly drained wet conditios
Soil & Site
average, well drained
Temperature
succumbs to the first frost
Flowers
doubles, yellows peach, pink, white, etc., close up on rainy or cloudy days and at night.
Leaves
prostrate or ascending succulent plant with reddish well branches stems, a moss-like appearance, hence the common name Moss Rose.
Maintenance
very little, dead heading, reseeds it self
Propagation
I find direct seeding the small seeds into a small container, such as cell pacs and allowing them to reach transplanting size is easier than using a seed flat and transplanting the very small seedlings into the growing container. Allow about 4-5 weeks from seed to garden.
Native Site
Native to Brazil.
Misc Facts
Portulaca comes from the Latin words porto-to carry and lac-milk.
