Also known as: Information to be completed

H. multifidus subsp. istriacus is a deciduous herbaceous perennial, up to 30cm high, with green leaves, the young leaves sometimes with coppery tints and the leaflets divided into ten to fourteen finely-serrated segments. Nodding flowers appear from late winter to spring; they are cone- to cup-shaped, 4-5.5cm across, green and sometimes tinted with purple on the outsides, and with a scent that is sometimes said to be reminiscent of Ribes sanguineum

Watering

Moderate regular watering, allowing brief slight drying between soakings

Fertilizing

Balanced perennial feed every four weeks from spring through summer

Pruning

Remove old leaves to help prevent hellebore leaf spot; old faded flower stems can be deadheaded, but if they are left the plants will self-seed

Propagation

Propagate by seed (to avoid unwanted hybrids, allow seeding only if grown away from other hellebores) or by division of large clumps in early spring, watering well until they are established

Growing

Grow in fertile, moisture-retentive, humus-rich but very well-drained soil which is preferably alkaline, in light dappled shade and with shelter from strong, cold winds, and mulch every autumn with leaf mould, chipped bark or other organic matter; for more advice, see hellebore cultivation
