Garrya elliptica

Growing in Pots, Balconies & Indoors

The silk tassel bush is grown for its dramatic dangling winter catkins. The grower rates it for containers but not indoors – it is a substantial evergreen shrub that wants full outdoor light and open air.

Quick Details

• Container Size: A large tub, 30-50 L (8-13 gal), scaled to the shrub
• Indoor Suitability: Not a houseplant (grower); an evergreen shrub for outdoor pots
• Best Spot: Full sun to partial shade; a bright spot with some direct sun is ideal.
• Soil & Drainage: Aerated, organic-rich mix (quality potting mix, or peat/coir with perlite or vermiculite); it must drain freely.
• Watering in Pots: Keep the mix evenly moist, letting the surface dry slightly between waterings; pots dry faster than open ground.

Indoors & On the Windowsill

• Not a houseplant: The grower marks it unsuitable indoors; it is too large and light-hungry for a room, and its winter catkin display is an outdoor feature.
• Shelter, don’t heat: It is fairly hardy – keep it outdoors, giving only wind shelter rather than bringing it into warmth.

On a Balcony or Patio

• Light & exposure: Sun to part shade suits it; it tolerates coastal wind well, which makes it a good tough-balcony shrub. Water pots in dry spells.
• Practicalities: A large evergreen in a tub is heavy and catches wind – anchor or place it against a sheltering wall.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A large tub with strong drainage holes; skip a standing-water saucer. Terracotta breathes and dries fast; glazed or plastic holds moisture longer.
• Potting mix: Use a well-aerated, organic-rich mix – quality potting mix, or peat/coir blended with perlite or vermiculite.
• Feeding: As nutrients wash out of pots faster than open ground, feed potted plants regularly through the growing season with a balanced fertiliser.
• Repotting: Refresh the top few centimetres of mix each year and pot up (or root-prune and return to the same pot) about every two years.

Bloom & Flower Guide

Quick Details

• Bloom Season: Winter into spring
• Flower Appearance: Long, slender, silvery-grey catkins hanging down; male and female flowers on separate plants, the males far showier
• Edibility: Grown as an ornamental (its parts are bitter) – not eaten

Detailed Blooming Overview

Silk tassel bush earns its name in the depths of winter, when it drapes itself in long, weeping catkins. Plants are dioecious – male and female on separate individuals – and it is the male plants, with tassels that can hang well over the length of a hand, that put on the real show. Because the display comes when little else is in flower, it is a valued winter shrub.

Flower Characteristics

• Flowers gathered into long, pendent, greyish-white catkins.
• Male and female flowers on separate plants; males carry the longest, showiest tassels.
• Peak interest in the middle of winter.

Bloom Care & Thinning

• Choosing plants: For the best winter display, select a named male form.
• Pruning: Trim lightly after flowering to keep the shape without sacrificing next year’s catkins.
• Pollination: Wind plays a large part in pollinating the catkins, with some insect visits.
