About this plant
This clump-forming plant spreads to form dense ground cover. It is handsome with big, albeit coarse, leaves coloured rich green and broadly lance-shaped. In spring, there are creamy flowers from orange buds which make long, tubular, bells and are held in clusters slightly above the foliage. After this brief sortie into glamour, it settles down to its role of groundcover and fares best in cool, moist conditions with shade, exactly the conditions that are likely to be found in a wood.

Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Spring - early-mid · Planting
Divide when too large
The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.
