Technical Specifications

The Ultimate Low-Maintenance Summer Flower

Moss Rose (Portulaca grandiflora) is legendary among gardeners for its ability to thrive under scorching heat and harsh drought conditions where most decorative annuals fail. Featuring fleshy, needle-like foliage that stores water, this resilient plant blankets bare spots with brilliant double blossoms in shades of vivid red, neon pink, deep rose, glowing orange, bright yellow, and pristine white.

Key Highlights & Benefits

• Unbeatable Heat & Drought Tolerance: Perfectly suited for hot climates, summer heatwaves, and water-restricted gardens.
• Continuous Summer Bloom: Flowers continuously from early summer right up until the first fall frost.
• Low-Nutrient Soil Friendly: Thrives in dry, sandy, rocky, or nutrient-poor soils without heavy fertilizers.
• Pollinator Magnet: Attracts honeybees, wild bees, butterflies, and beneficial garden insects throughout the day.

Master Sowing & Growing Guide

1. Soil Preparation & Location

• Location: Select a spot that receives at least 6 hours of unshaded, direct sunlight daily.
• Soil: Prefers dry to medium-moisture, well-drained soil. Amend heavy clay with coarse sand, perlite, or gravel to prevent water stagnation.

2. Sowing Method (Indoor vs. Direct Outdoor)

• Direct Outdoor Sowing (Recommended): Wait until all frost danger has passed and soil temperature reaches 65°F–75°F (18°C–24°C). Scatter seeds over prepared soil and press lightly into the surface.
• Light Required for Germination: Do not bury or cover the seeds with soil. Moss Rose seeds are micro-fine and require direct ambient light to trigger germination.
• Indoor Seed Starting: Start indoors 6–8 weeks before the last spring frost in shallow flats using a fine peat-perlite starter mix.

3. Watering & Moisture Management

• Germination Stage: Mist gently with a spray bottle to keep the top layer moist without washing away the tiny seeds.
• Established Stage: Water sparingly. Let the top 1–2 inches of soil dry out completely between waterings. Overwatering is the #1 cause of growth issues.

4. Thinning & Spacing

• When seedlings reach 1–2 inches tall, thin to 6–8 inches apart for airflow, to prevent fungal damping-off, and to encourage vigorous lateral spreading.

Garden & Landscape Design Applications

• Rock Gardens & Xeriscaping: Fills rocky crevices and gravel beds with brilliant color while requiring zero irrigation once rooted.
• Retaining Walls & Slopes: Cascades gracefully over dry-stone walls and stabilizes sunny, dry embankments.
• Container & Hanging Basket Spill Points: A striking “spiller” in patio pots, window boxes, and hanging baskets mixed with other sun-loving succulents.
• Pathway Edging: Defines garden borders with a dense, colorful floral edge.

Common Growing Problems & Solutions

• Flowers Staying Closed: Cause: insufficient direct sunlight or overcast weather. Fix: ensure full afternoon sun; flowers naturally close in shade and at night.
• Stem Rot or Yellowing Foliage: Cause: overwatering or poorly draining soil. Fix: reduce watering and improve drainage by mixing in grit or sand.
• Leggy Growth: Cause: lack of sunlight or excess nitrogen. Fix: avoid high-nitrogen fertilizers; prune back leggy stems for bushier growth.

Frequently Asked Questions

How many seeds are included in this package?

This pack contains 6,000 fresh Moss Rose (Portulaca grandiflora) seeds, providing ample coverage for large garden beds, borders, or multiple container setups.

Why is Moss Rose called the “Eleven O’Clock” flower?

The blooms open fully during the brightest hours of the day—usually mid-morning around 11:00 AM—and gently close as the sun sets or on overcast days.

Does Moss Rose reseed itself?

Yes. While grown as an annual in most climates, it readily drops seeds at the end of the season, often self-sowing and producing new volunteer seedlings the following spring.

Is Moss Rose safe for home gardens with pets?

Portulaca grandiflora contains soluble calcium oxalates, which can be toxic to dogs and cats if ingested in large quantities. Keep plants out of reach of inquisitive pets.
