Purslane is not just purslane: There are roughly two different types of purslane, both of which are used as wild salad or vegetables and are very rich in vitamin C, various minerals and omega-3 fatty acids. The summer purslane (Portulaca oleracea) loves the warmth and is therefore cultivated in summer. The plants can grow up to 40 centimeters high. In contrast, the cold-resistant winter purslane (Claytonia perfoliata) only belongs in the bed in autumn, as it provides fresh vitamins and minerals throughout the winter. It is also known as Cuban spinach or Postelein.
Which location does purslane prefer?
Summer purslane prefers a sunny and warm location with loose, humus-rich and moist soil. Winter purslane, on the other hand, has a low light requirement and needs a rather slightly sandy substrate.
How is purslane planted or sown?
The best germination temperature for summer purslane is around 20 to 22 °C, which is why the seeds can only be spread in the bed from the end of May. The plants can also be grown in pots. Summer purslane needs light and germinates within five to ten days. Winter purslane, on the other hand, is a flowering plant whose seeds should be covered with soil about ten millimeters thick. It is also a cold germinator that germinates best at temperatures below 12 °C. The seeds are sown directly outdoors from the end of September / beginning of October.
What planting distance should be maintained?
A distance of about 15 x 15 centimeters should be maintained for both types of plants, with the summer purslane becoming significantly larger and therefore requiring more space.
Do I have to prefer purslane?
Summer purslane should be preferred on the windowsill, while winter purslane feels most comfortable in the bed.
How is purslane propagated?
Both types of purslane reliably seed themselves, but quickly overgrow any garden. The edible seeds are ready within six weeks of flowering.
How can I combat rampant purslane?
Purslane can only be prevented from growing if you cut the flowers of the plants in good time and thus prevent the seeds from forming.
When can I harvest purslane?
Purslane can be harvested several times a year. Summer purslane is harvested for the first time four to six weeks after sowing; Winter purslane, however, only when the petioles are about ten centimeters long. Purslane should not be harvested after flowering, otherwise it will taste bitter.
