About Lily

A scaly bulb with no protective skin, so it dries out quickly. Many lilies also root from the stem above the bulb.

Depth and spacing

Typical range: 15-20 cm deep and 20-30 cm apart. A general rule is to plant at two to three times the height of the bulb; check the label for your variety. The drawing is to scale for 17.5 cm deep and 25 cm apart (the size of the organ is illustrative); try your own measurements.

When to plant

Plant in autumn. Plant: from your first autumn frost to 6 weeks after. These are rules of thumb for the northern hemisphere. Enter your frost dates for real dates.

Dividing and propagating

Lift in autumn and break off outer scales or offsets; scales planted in damp compost make bulblets in a few months. Bulbils on stems of some species are also sown.

Lifting and storing

Plant promptly; if stored, keep in barely moist peat-free compost or sawdust in a cool place.

Toxic to Cats

The ASPCA lists Lilium species as: toxic to cats. Signs: Cats: kidney failure. If your pet has chewed any part, call your vet or an animal poison helpline. ASPCA entry.
