Overview

Huge, sculptural, corrugated grey-blue leaves are topped with spikes of trumpet-shaped flowers of the palest lilac in July and August. When the plant has finished flowering, the seed pods split into tiny, star-like segments. The striking leaves of this plantain lily make a dramatic full stop at a woodland edge, where they contrast beautifully with ferns and other foliage plants. Once established, its layers of leaves will suppress weeds, too.

Specifications

  • Soil: fertile, moist, well-drained soil

Care guide

You'll get thicker, lusher leaves if you give your hostas a really good feed. An annual mulch in spring or autumn will help to keep the weeds down and is an easy way to improve soil and boost nutrient levels. Add a generous mulch of about 5-10cm (2-4in) deep of garden compost or leaf mould around the plant. Spraying the leaves regularly with a high nitrogen fertiliser during the growing season will also help to boost leaf size. Slugs and snails love hostas, so you will need to protect against them. Use an organic nematode treatment in early spring to ward off slugs. Or simply stick to planting it in a container. Water your hosta well as soon as you plant it and from then on water regularly during their first growing season. Give them a water about once or twice a week around the base of the plant, avoiding the leaves. Little and often can be disastrous as it encourages the plant to produce roots closer to the surface in a desperate quest for moisture.

How your order will arrive

Pots and Packaging
Bare root plants are either wrapped in plastic bags or waxed paper where possible and then placed into a cardboard box.

Preparation
The nursery will ensure the plant is moist while it's waiting to be picked up. Our quality control team waters the plant before packing them where necessary to make sure that the plant is suitably watered for transport. Plants with long delicate stems are secured with canes to prevent damage.

Plant on Arrival
Typically plants are delivered ready to plant and will take some time to settle, grow and look more like the product image above.
