  • 🌸 Rich color – glowing tangerine-orange blooms for bold contrast.

  • 🌿 Compact and spreading – perfect for ground cover or edging.

  • 🪴 Ideal for containers, rock gardens, and baskets.

This is a perfect choice for home gardeners, landscapers, and greenhouse growers looking for a low-maintenance, high-impact annual that performs beautifully in extreme heat.


How to Start Portulaca Seeds Indoors

Starting Portulaca from seed is easy, especially with multi-pelleted seeds, which make handling and sowing simpler. Follow these professional growing steps for best results:

  1. Start indoors 6–8 weeks before the last frost.

  2. Use a sterile seed-starting mix in plug trays or shallow flats.

  3. Gently press the seeds into the soil surface – do not cover, as Portulaca needs light to germinate.

  4. Maintain 70–75°F and 10–12 hours of light daily.

  5. Keep humidity high until germination, which occurs in 8–18 days.

  6. Transplant when seedlings have 3–4 true leaves.

Transplanting and Growing On

Once the weather warms and frost danger has passed, move your seedlings outdoors. Portulaca Sundial Tangerine performs best in sandy, well-drained soil and direct sunlight.

Ideal Growing Conditions:

  • Spacing: 6–8 inches apart.

  • Height: 4–6 inches tall.

  • Spread: 10–12 inches wide.

  • Light: Full sun (10–12 hours daily).

  • Watering: Let soil dry between waterings.

Avoid heavy, rich soils or overwatering, which can reduce blooming and cause rot. The less pampered Portulaca is, the better it blooms!
