Juniperus sabina

Growing in Pots, Balconies & Indoors

Savin juniper (Juniperus sabina) is a tough, low, spreading evergreen shrub, 0.7-3 m (28-120 in) high and wide. The grower does not class it as a houseplant, but it grows well in containers, which makes it a good spreading shrub for a sunny balcony or a large trough. Important: savin juniper is toxic to people and pets – keep the foliage away from children and animals and wear gloves when pruning.

Quick Details

• Container Size: A broad, low tub or trough suits its spreading habit; pot up as it widens
• Indoor Suitability: Not a houseplant, per the grower; grow it as an outdoor container shrub
• Best Spot: Full sun to part shade on a balcony or patio
• Soil & Drainage: Free-draining, gritty, loam-based mix; strong drainage holes
• Watering in Pots: Water when the top of the mix dries; it is drought-tolerant and hates waterlogging

Indoors & On the Windowsill

• Not a houseplant (grower): The grower marks it as unsuitable indoors – grow it outdoors in a container instead.
• Cold-hardy: Being hardy, it needs no indoor overwintering and prefers to stay outside.
• Safety: Savin juniper is toxic – keep it away from children and pets and handle with gloves.

On a Balcony or Patio

• Light & wind: An excellent spreading container shrub for full sun to part shade; a broad, low trough shows off its habit and stays stable in wind. Site it where children and pets will not brush the toxic foliage.
• Practicalities: Very drought-tolerant, but pots warmed by walls still dry faster – check occasionally, and make sure runoff drains freely.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A broad, low tub with strong drainage holes; skip a standing saucer of water to avoid root rot – it hates wet feet.
• Potting mix: A gritty, free-draining loam-based mix suits this tough shrub.
• Feeding: Feed lightly through the growing season; pot nutrients leach faster, but it is not a hungry plant.
• Repotting: Refresh the mix and pot up every couple of years; lightly trim to shape (wearing gloves).

Bloom & Flower Guide

Quick Details

• Bloom Season: Spring
• Flower Appearance: Not true flowers but small yellowish cones — male and female borne on separate plants
• Edibility: Not edible — savin juniper is toxic in all its parts, unlike the edible common juniper

Detailed Blooming Overview

As a conifer, savin juniper doesn’t flower in the true sense — what looks like the bloom in spring are its small cones. The plant is dioecious, so the yellowish pollen cones and the seed cones sit on separate male and female plants, and pollen simply drifts between them on the wind. It is a tough evergreen for hedging and ground cover, but every part of it is poisonous.

Flower Characteristics

• Yellowish cones rather than petalled flowers.
• Male and female cones on separate plants.

Bloom Care & Thinning

• Pollination: Wind-pollinated, so no insect visitors are needed for the female plants to set cones.
• Safety: Do not eat any part and take care when pruning — the foliage and cones are toxic and the sap can irritate skin.
