Portulaca is not hardy enough to survive outdoors in frost. Although it’s treated as an annual, in the South, portulaca self-seeds and will return year after year.

Can portulaca survive winter?

Portulacas are annuals in U.S. Department of Agriculture zones 2 to 11, although they may survive winters in zones 10 and 11. Even when they die off after a frost, these fast-spreading plants drop seeds as they flower, and it’s not uncommon for the seeds to sprout the following year.

How do you revive portulaca?

To bring back your portulaca in the springtime, simply start watering again. Start slowly and then increase the amount you water each week until the start of the summer.
