If you're growing your portulaca plants from seed, take care not to over-sow the tiny seeds, which are as small as pepper flakes and need light to germinate. You can start the seeds indoors eight weeks before your last frost date for earlier flowers, or plant them in the ground after the last frost.

How do you keep Portulaca blooming?

Drainage: Moss roses prefer poor, dry, well-drained soil. If portulaca won't bloom, it may be because the soil is too rich or too soggy. Although you can add sand or a small amount of compost to the soil, it may be easier to start over in a new location. (You can also plant moss roses in containers.

Will Portulaca grow in shade?

It is especially well suited to coastal gardens because it requires full sun -- on cloudy days or in shade, portulaca blooms will not open -- and only poor, gravelly soil that drains quickly. The small, fleshy leaves store water, allowing the plant to survive during dry periods.

How often do you water Portulaca plant?

Watering Sparsely
During a prolonged drought, however, you can help keep flowers coming nonstop by watering the plant sparsely every week or two, but water only at the root zone with a soaker hose or drip irrigation to avoid damaging flowers.

How tall do Portulaca grow?

Many gardeners are familiar with the annual purslane weed, which self-seeds prolifically. Moss rose plants grow as much as 8 inches tall, and spread 1 to 2 feet to create a dense mat, making the plant a good groundcover.

Do you deadhead Portulaca?

Portulaca is one of those "easy-care" plants that requires no deadheading. The plants have a reputation for self-sowing, though, so if you don't want seeds to form (and spill into the bed), you can remove the spent blooms. Portulaca will bloom through late autumn whether or not you deadhead, so the choice is yours.

Can you transplant Portulaca?

Portulaca, an annual, is strictly a summer plant and will die with the first frost of the season. It is a sturdy succulent, and when transplanted, it easily adapts to its new home. Prepare the soil ahead of time by loosening the top 3 to 4 inches. Transplant the portulaca as soon as possible so the roots don't dry out.

Can you plant portulaca in the ground?

Does purslane come back every year?

In Montana every purslane plant dies every winter. Next year's plants come from seed produced in previous years. Since they must start anew from seed, the first purslane plants do not become visible until mid-June. Since purslane can grow from a piece of stem, a whole plant is not required for regeneration.

How do you keep moss roses blooming?

But moss roses are also self-seeding annuals, so in order to have the plants emerge again the next spring you need to allow them to retain their flowers long enough to produce and drop seed. If you don't want them to seed, pinch the bloom from the plant about 1/4 inch into the stem once the flower begins to fade.

Will Portulaca reseed itself?

The plant grows to a half-foot-wide mound, with stems that are just barely able to pull themselves up off the ground under the weight of their fleshy leaves. The plant is an annual but sometimes will reseed itself for the next season. Portulaca--the weed and vegetable--is also known as purslane.

Can Portulaca grow from cuttings?

Cut a 2- to 5-inch piece of portulaca off of the mother plant. Remove just the bottom leaves of the cutting. Prepare the planting bed as you would for seedings and place the cuttings, bare stem down, into the soil. Water well and then don't water again until the top 2 inches of soil are dry.
