Portulaca oleracea

Growing in Pots, Balconies & Indoors

Purslane (Portulaca oleracea) is a low, fleshy, edible succulent that positively thrives in a pot – it loves heat, sun and sharp drainage. It is not a houseplant, but its small size and love of light make it a natural for a sunny windowsill, a hot balcony or a patio trough.

Quick Details

• Container Size: Shallow pot or trough, 3-10 L, wide and free-draining
• Indoor Suitability: Not a true houseplant, but happy on the sunniest sill
• Best Spot: Full sun and warmth
• Soil & Drainage: Gritty, sharply draining mix – it stores water in its leaves
• Watering in Pots: Water lightly and let the mix dry between drinks; it shrugs off drought

Indoors & On the Windowsill

• Houseplant limits: The grower does not rate it as an indoor plant – it needs strong sun to stay compact and fleshy.
• Windowsill growing: A hot, sunny sill suits its low, spreading habit; keep it on the dry side and pick young shoots and leaves for the kitchen.

On a Balcony or Patio

• Light & wind: Give it the hottest, sunniest, airiest spot you have – it thrives on the fast-drying conditions of a sunny balcony. Reflected heat from walls and railings suits it, but check the pot in the peak of summer so it never bakes bone dry for long.
• Practicalities: Make sure the filled pot’s weight is safe for the balcony and that water drains away freely rather than sitting in the base.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A shallow 3-10 L pot or trough with plenty of drainage holes; never leave it standing in a saucer of water – wet roots are the quickest way to kill it. Terracotta suits it well, breathing and drying faster than glazed or plastic.
• Potting mix: A sharp, free-draining mix – potting soil or peat/coir cut with extra perlite, grit or sand so water runs straight through.
• Feeding: Feed only lightly; this is a lean-soil plant, and too much food in a pot gives soft, floppy growth. A little through the growing season is plenty.
• Repotting: Refresh the mix or pot up about every couple of years, trimming the roots and shaping the top as you go.

Bloom & Edible Flower Guide

Quick Details

• Bloom Season: Summer into autumn
• Time to First Bloom: Within the first season – this fast annual flowers within weeks of germinating
• Flower Appearance: Small yellow flowers that open in bright sun, often only for a few morning hours
• Edibility: Edible – common purslane is a well-known edible plant, and the tender tops including the flowers can be eaten

Detailed Blooming Overview

Common purslane is a sprawling succulent that flowers freely all summer. The little yellow blooms open in strong sunshine and close again by afternoon, then quickly set tiny seed capsules – which is why one plant can seed a whole bed.

Flower Characteristics

• Small, five-petalled yellow flowers tucked among the fleshy leaves.
• Open in bright sun and close in dull weather or later in the day.

Bloom Care & Thinning

• Managing the bloom: Pinch back flowering shoots to keep new growth tender and to slow self-seeding; leave some to flower for pollinators or seed.
• Pollination: Visited by flies and bees, and readily self-pollinating.
