Cultivation Instructions

Before planting cultivate soils to a depth of 10cms at least and add well rotted humus matter to poor soils. Plant the rhizomes about 5cms deep length ways. They will grow well in a peat bed. Once planted they are best left undisturbed for a number of years and they will gradually build up into large clumps. They can be shy flowering in the first year so be patient and let them establish themselves.

Growing Information

Flowering height: 12″ (30cm)

Flowering time: April

Aspect: Ideal for shady areas in the garden, especially amongst deciduous trees.

Soil type: Grow well in a peat bed with plenty of drainage. Multi purpose compost is not a good medium to grow them in.

Division – Established clumps can be lifted and divided as the foliage dies back. Ensure each piece of rhizome has at least one bud and some roots. Lateral buds can be encouraged by scoring. To do this, scrape back the soil after flowering and score around the base of the terminal bud with a sharp knife. By the following year this will often result in several lateral buds or offsets that can be detached and grown on.

New season top quality bulbs dispatched from September onwards
