Portulacaria afra

Growing in Pots, Balconies & Indoors

Portulacaria afra (elephant bush or spekboom) is a fleshy, easy succulent shrub. The grower lists it as an outdoor container plant rather than a houseplant, and it does grow biggest and best in full outdoor sun – but it is also one of the most popular indoor succulents and bonsai subjects, thriving on a bright, sunny windowsill.

Quick Details

• Container Size: Flexible – from a small bonsai pan up to a 10-20 L tub for a large shrub; it takes very happily to pots and pruning
• Indoor Suitability: Grows indoors on a very bright, sunny windowsill (a favourite succulent/bonsai); for full, dense growth it prefers outdoor sun
• Best Spot: Full sun to half shade outdoors; the brightest possible sill indoors
• Soil & Drainage: Gritty, free-draining succulent/cactus mix
• Watering in Pots: Little to moderate – let it dry between waterings; drought-tolerant and easy

Indoors & On the Windowsill

• Two ways to see it: The grower keeps it as an outdoor container plant, where full sun gives the strongest growth. That said, elephant bush is widely and successfully grown indoors as a succulent houseplant and bonsai – the key is the brightest, sunniest window you have.
• Windowsill growing: On a hot, sunny sill it stays compact and colours up; in weak light it grows soft and leggy. It is easy to prune and shape, which is why it is such a popular indoor bonsai.
• Overwintering: Frost-tender, so in cold climates keep it in a pot and bring it to a bright indoor spot for winter.
• Note: It is non-toxic – the leaves are in fact edible and it is considered safe around pets, a bonus for an indoor succulent.

On a Balcony or Patio

• Light & heat: Loves a hot, sunny balcony and reflected wall heat; very drought- and wind-tolerant, and a superb low-water container plant.
• Practicalities: Lightweight for its size and forgiving of missed waterings; just ensure pots drain freely.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: Any pot with strong drainage holes and no standing saucer; terracotta is ideal for a succulent.
• Potting mix: Gritty cactus/succulent mix with extra perlite, grit or pumice.
• Feeding: Feed sparingly in the growing season; too much gives soft growth.
• Repotting & pruning: Pot up or root-prune every couple of years; it responds very well to pruning, making it easy to keep at any size – ideal for bonsai.

Bloom & Flower Guide

Quick Details

• Bloom Season: Summer to autumn
• Time to First Bloom: Only well-established, mature plants bloom, and flowering is uncommon in cultivation
• Flower Appearance: Clusters of tiny white to pink star-shaped flowers
• Edibility: The plant itself is non-toxic and pet-safe (its tart leaves are eaten in its native South Africa), but the flowers are grown for show rather than for the kitchen

Detailed Blooming Overview

Portulacaria afra – elephant bush – rarely flowers as a potted houseplant. Given age, strong light and a dry-then-watered cycle, a mature plant can produce a haze of small star-shaped white-to-pink flowers in summer and autumn, set in clusters along the reddish stems.

Flower Characteristics

• Tiny, star-shaped flowers in white or pink.
• Carried in small clusters along the branches.
• Nectar-rich and attractive to bees.

Bloom Care & Thinning

• Coaxing bloom: Maturity, plenty of bright light and a lean, dry-then-watered routine are the main triggers; avoid heavy feeding.
• Let it be: No thinning is needed – simply enjoy the flush and tidy spent flowers afterwards.
• Pollination: Bees visit the small nectar-rich flowers.
