Stephanotis floribunda

Growing in Pots, Balconies & Indoors

Madagascar jasmine is not a deep-room houseplant – the grower marks it unsuitable for indoors – but as a tender twining vine (3-5 m / 10-15 ft) it does well in a bright conservatory or on a sunny sill with a hoop to climb, and a pot lets you carry it through cold weather. It needs strong light to flower, so a shaded room won’t do.

Quick Details

• Container Size: A pot of about 15-25 L (4-6 gal) with a hoop or trellis
• Indoor Suitability: Not a shady-room houseplant; grows on a bright, sunny sill or conservatory
• Best Spot: Full sun to part shade; bright light indoors to trigger flowering
• Soil & Drainage: Free-draining, organic-rich mix
• Watering in Pots: Keep evenly moist in growth, drier and cooler in the resting season; it likes average to generous water when active

Indoors & On the Windowsill

• Bright light needed: Away from strong light it won’t flower – keep it right at a sunny window or in a conservatory, trained around a hoop.
• Windowsill growing: A warm, bright sill suits a young plant; give it steady warmth and humidity and avoid moving it once buds form.
• Overwintering: Frost-tender and the main reason to pot it – keep it in a cool but frost-free, bright spot over winter, watering sparingly. The sap and parts are mildly toxic, so keep away from children and pets.

On a Balcony or Patio

• Light & wind: A warm, sheltered, sunny balcony suits it in the warm season; shelter from cold wind and provide a support.
• Practicalities: Bring it under cover before the first cold snap – it resents chilling.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A 15-25 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: Spring through autumn
• Flower Appearance: Waxy, pure-white, five-petalled star-shaped flowers, heavily fragrant, in clusters
• Edibility: Ornamental — a classic cut and wedding flower, but not eaten; like others in the dogbane family it has a milky sap

Detailed Blooming Overview

Stephanotis is grown for its intensely fragrant, waxy white stars, long a favourite in bridal bouquets. It flowers from spring into autumn on a twining evergreen stem and rewards warmth, bright light and steady moisture. Though called a jasmine, it is unrelated to true jasmine and is not for eating.

Flower Characteristics

• Waxy, five-petalled, pure-white star-shaped flowers, strongly scented, borne in clusters.

Bloom Care & Thinning

• Encouraging bloom: Bright indirect light, warmth and humidity bring the flowers.
• Protecting the buds: Avoid moving plants in bud, which causes bud drop.

Bloom Health & Protection

• Aphids and scale on buds: These can attack soft buds and stems; neem oil or horticultural oil helps.
