Does creeping Jenny spread?

Yes, quickly. The RHS notes it can become a nuisance if not managed. Trim it back regularly to keep it where you want it.

Is it good for wildlife?

The flowers are visited by bees, hoverflies and butterflies, and the trailing stems give small pond creatures shelter.

Is creeping Jenny poisonous?

The RHS Plants shop lists it as toxic if eaten and as a skin and eye irritant, so wear gloves when handling it.

Which size should I buy?

Bare-root plants (7 cm, 9 cm, 1 litre and 3 litre) arrive without a pot or compost and are the most economical way to plant a group. Potted plants (9 cm, 1 litre and 3 litre) arrive growing in our peat-free compost and give a faster display. Packs of 3 come in 7 cm, 9 cm, 1 litre and 3 litre bare-root sizes and cost less per plant. The 2x Pot & Compost option is two plants supplied with pots and compost.
