What is a Portulaca?
Portulaca is a genus of plant in the family Portulacaceae, native to South America.
The common name purslane can refer to any member of this genus, as well as to the unrelated plant known as littleleaf
pigweed (Trianthema portulacastrum).
The plants in this genus are typically succulent herbs with trailing or prostrate stems.
The leaves are fleshy and often coloured, and the small flowers are borne singly or in clusters on the leaf axils.
Many species flower only during bright sunshine.
Some members of this genus are cultivated as ornamental plants, particularly in dry conditions.
They are sometimes considered weeds, however, because they can spread rapidly and be difficult to control.
The best-known species is probably Portulaca grandiflora, which is widely cultivated as a garden plant.
It has been introduced to many other regions, and is often seen growing as a weed in disturbed areas.
Other popular ornamental species include Portulaca oleracea (also known as common purslane or green purslane) and
Portulaca umbraticola (also known as sun rose or moss rose).
When To Plant Portulaca?
It can be planted at any time of year, but it is best to sow the seeds in late spring or early summer.
The plants will flower most profusely if they are grown in full sun, but they will also do well in partial shade.
How To Plant a Portulaca?
It is usually grown from seed.
The seeds can be sown directly into the ground where they are to grow, or started off in pots or trays indoors.
If you are starting the seeds indoors, sow them on the surface of a moist seed compost and cover with a thin layer of fine
grit or vermiculite.
Keep the compost moist but not wet and place the pots or tray in a warm location.
What are the Pros & Cons of Portulaca Plants?
It is a hardy plant that will tolerate a wide range of growing conditions.
It is very easy to grow from seed and will flower within a few weeks of planting.
The plants are also relatively drought-tolerant, so they are ideal for use in dry, sunny areas.
One potential downside, is that it can spread rapidly and become invasive in some areas.
It is also considered a weed in many parts of the world.
If you are growing portulaca in an area where it is not native, it is important to keep it under control to prevent it from
spreading too far.
