Dalechampia

Growing in Pots, Balconies & Indoors

Dalechampia is not a houseplant – the grower marks it unsuitable indoors – and as a vigorous flowering climber (2-6 m / 6-20 ft) it needs full sun and a support outdoors. It can be grown in a large container on a sunny balcony, but it is not a windowsill plant.

Quick Details

• Container Size: A large pot of about 25-40 L (6-11 gal) with a trellis
• Indoor Suitability: Not an indoor plant; grow it outdoors against a support
• Best Spot: Full sun to part shade
• Soil & Drainage: Free-draining, organic-rich mix
• Watering in Pots: Keep evenly moist in growth – it likes average to generous water

Indoors & On the Windowsill

• Not a houseplant: Too vigorous and light-hungry for indoors – it wants to climb and needs strong light to flower.
• Windowsill: Not practical; it soon outgrows any sill.
• Overwintering: Tender – in cold areas a potted plant can be sheltered under cover; the milky sap of this spurge relative can irritate skin, so prune with gloves.

On a Balcony or Patio

• Light & wind: Give it a warm, sunny spot and a firm support; shelter from cold wind.
• Practicalities: Prune to keep a potted plant in bounds; pots dry quickly in the sun.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A large 25-40 L pot with strong drainage holes; skip a standing-water saucer to avoid root rot. Terracotta breathes and dries faster; glazed or plastic holds moisture longer.
• Potting mix: A light, aerated, organic-rich mix – potting compost or peat/coir with added perlite or vermiculite for drainage.
• Feeding: Nutrients wash out of pots faster than open ground, so feed potted the vine more often – a balanced liquid feed through the active growing season.
• Repotting: Refresh the top layer of mix each year and renew it or pot up every couple of years; lightly trim the roots and top growth when you do.

Bloom & Flower Guide

Quick Details

• Bloom Season: Summer to autumn
• Flower Appearance: Two large, petal-like bracts (pink, purple, white, green, orange or yellow) framing small true flowers, giving a “bat wing” or butterfly look
• Edibility: Ornamental – not eaten (a spurge relative whose sap may irritate)

Detailed Blooming Overview

The “bat flower” vine puts on its show through the warm months, though the colour comes from a pair of large coloured bracts rather than true petals – they frame the small central flowers like a bat’s or butterfly’s wings. It belongs to the spurge family, so its sap is best treated with care.

Flower Characteristics

• Paired coloured bracts (pink or purple, among other shades) around small yellow true flowers.

Bloom Care & Thinning

• Supporting the display: Train it on a support to show off the wing-like blooms.
• Handling: Wear gloves when pruning, as the milky sap can irritate skin.
