How to propagate Western Wild Ginger (Asarum caudatum) — step by step

Also called Western Wild Ginger, British Columbia Wild Ginger, Long-tailed Wild Ginger.

The best way to propagate western wild ginger

The reliable, beginner-friendly way to propagate western wild ginger is softwood tip cuttings in water or soil. It suits this species because of how it grows: evergreen, low-growing, creeping groundcover spreading by surface rhizomes; forms dense overlapping mats; flowers borne at or below soil level, hidden under foliage. Divide established mats in spring or early autumn; each section should include several nodes and healthy roots. Replant immediately and keep consistently moist until established. Seed propagation is possible but slow; sow fresh seed in autumn in a cold frame, as germination requires cold stratification and typically occurs the following spring.

For the wider picture of which technique suits which plant, our guide to plant propagation methods compares water, soil, leaf, division and offset propagation side by side.

Step-by-step: propagating western wild ginger

Take a tip cutting. Snip a 10–15 cm, non-flowering tip from healthy western wild ginger, cutting just below a leaf pair with clean scissors.
Strip the lower third. Pinch off the leaves on the bottom third of the stem and remove any flower buds — energy needs to go into roots, not blooms.
Root it. Stand the bare stem in water on a bright windowsill, or push it into moist seed compost and cover with a clear bag or dome to hold humidity.
Watch for roots. Roots show in 1–3 weeks. For woodier herbs like rosemary, sage and lavender, soil rooting under a dome is more reliable than water.
Pot on. Once roots are 2–3 cm, pot into humus-rich, moist, well-draining, slightly acidic to neutral loam and pinch the growing tip to encourage a bushy western wild ginger.

The alternative method

If the main route does not suit your plant or setup, direct-to-soil cuttings under a humidity dome is the next best option for western wild ginger. Skip the water glass and root several cuttings directly in gritty seed compost under a clear dome — this is the more reliable route for woody Mediterranean herbs that sulk in water.

Timeline to roots

Realistically: roots in 1–3 weeks; pot up at 3–4 weeks. These numbers assume spring or summer warmth and bright indirect light. In a cold, dark room — or in winter dormancy — the same western wild ginger propagation can take twice as long or stall completely, so do not panic if progress looks slow out of season. Patience beats poking: disturbing a forming root system to “check” on it is a common way to set it back.

Common failure points

Leaving flower buds on the cutting — it spends energy blooming instead of rooting.
Water-rooting woody herbs (rosemary, lavender, sage): they root far better in gritty soil under a dome.
Letting the cutting wilt before it roots — high humidity (a bag or dome) is what carries it through.
Propagating off a stressed, pest-ridden or recently-repotted western wild ginger — always take material from a healthy, established parent.

When to do it

The best window is spring through late summer. Propagation is energetically expensive for a plant, and it only has the spare resources to build new roots when it is already growing actively, warm and well-lit. Out-of-season attempts are not pointless, but expect lower success and a longer wait.

Aftercare

For the first two to three weeks after potting, keep the new western wild ginger slightly moister than you would a mature plant and out of direct sun while the young roots adapt from water (or cutting medium) to soil. Hold off all fertiliser until you see a flush of new top growth — feeding a rootless cutting only burns it. Match the parent's needs as the new western wild ginger settles: Naturally grows in deep to moderate shade under conifers and broadleaf trees. Tolerates low-light conditions better than most groundcovers. Avoid direct sun, which scorches the foliage. Dappled shade with north or east exposure is ideal.

Western Wild Ginger propagation — frequently asked questions

What is the best way to propagate western wild ginger?

Softwood tip cuttings in water or soil is the most reliable method for western wild ginger. Propagate western wild ginger from a 4–6 inch softwood tip cutting. Strip the lower leaves, then root the bare stem in water or moist potting mix in bright indirect light. Roots form in 1–3 weeks and the cutting is ready to pot on at 3–4 weeks. Spring and summer are fastest.

Do you need a node to propagate western wild ginger?

For western wild ginger the rooting structure is softwood tip cuttings in water or soil, so a classic "node" matters less than starting with the right plant material — Strip the lower leaves, then root the bare stem in water or moist potting mix in bright indirect light.

How long does it take western wild ginger to root?

Roots in 1–3 weeks; pot up at 3–4 weeks. Timing varies with warmth and light — propagations move fastest in spring and summer when the plant is in active growth, and can stall almost completely in a cold, dark winter.

What is the best time of year to propagate western wild ginger?

Spring through late summer. Root and shoot development is metabolically demanding, so propagating during the active growing season gives noticeably higher success rates and faster results than attempting it in dormancy.

Can you propagate western wild ginger in water?

Yes — western wild ginger roots readily in a glass of water as long as a node is submerged. Water propagation is the most beginner-friendly route; just move the cutting to soil before the water roots get long and brittle (around 3–5 cm).
