About Moss Rose

Moss Rose, also known as Portulaca, is a low growing annual that puts out a lovely rainbow of colors including red, pink, yellow, white, and purple. Often used as a groundcover, they’re common in rock gardens, containers, flower beds, and walkways.

When to Plant Moss Rose Seeds

Sow seeds directly in the garden after the last frost date, or start indoors 6-8 weeks earlier and transplant after last frost.

Where to Plant Moss Rose Seeds

Moss Rose thrives in full sun in dry to moderately moist, poor to average, well-drained soils. It can tolerate some afternoon shade in hot summer climates and is drought tolerant once established but performs best with regular food and water.

How to Plant Moss Rose Seeds

Moss Rose seeds require light to germinate, so be careful not to cover them when planting. Learn more about germination light requirements here.

If starting indoors, sow seeds into starter trays or individual pots. Press into soil, but do not cover, as seeds need light to germinate. Transplant seedlings or direct sow seeds 12″ apart. Germination takes approximately 7-14 days.

How to Care for Moss Rose

While Moss Rose can tolerate heat and drought, they look best with occasional watering. Keep soil slightly moist, but not wet until germination. Cut back plants during the summer to help extend fall blooms.
