About this plant
This is a biennial or a short lived perennial that should set seed. It is generally too tender to winter outside in Britain and Ireland. It makes a dramatic, silvery-green, rosette of long, slender, lance shaped, leaves; closely packed and radiating out from the centre in a lively, characterful, fashion. The leaves are around 20cm (8in) long. It flowers from late spring when it sends up a dramatic flowering spike making a great column of tubular, red flowers. A colony on a hillside in the Canaries is a sight not to be forgotten. When the flowers are over the skeletal, silvery remains of the column are retained. When in flower this will reach 2m (7ft) height with 60cm (2ft) spread.

Spring
Spring - late · Indoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of plants soon after they have come into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Indoors
Water regularly during growth
Water regularly while in growth.
Adopt a regime that means the plants are thoroughly watered every week so that they do not become dessicated. In hot weather watering may need to be more frequent, but less often in cool or moist conditions.

Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Winter
Winter-Spring · Indoors
Water lightly in winter
The soil should remain just moist during the cold months when the plant is not in growth. Trickle a little water onto the soil surface every couple of weeks if the soil is dry. Do nothing if it is moist.
The roots remain active in winter and benefit from small amounts of moisture so they don't become completely desiccated.
Winter · Planting
Apply a protective mulch
Protect with a mulch so that the plant does not become too wet in winter.
A mulch is a covering that can: protect the soil surface from rain, heat and cold; deter weeds; provide nutrients. Organic indicates that material has vegetative origin e.g. manure, compost. Synthetics i.e. plastics, or stones are often called mulches.
Planting & general
Compost · Planting
Loam based houseplant compost for repotting
Buy container or house plant compost that is loam based if possible (i.e. is based on John Innes compost number 2 or 3. This contains more fertiliser and is better suited to established plants.
John Innes no. 1 has the lowest level of fertiliser and is used for seedlings and young plants, so is generally used where plants will be 'potted on' after a number of weeks.
Indoor temperature · Planting
7C minimum temperature
This plant requires a minimum temperature of 7 Centigrade.
Indoor plant · Planting
Position in a sunny spot, close to window
Give this plant a position where there is as much light and sunlight as possible, within 2-3 metres of a sunny or bright window (one that is south, east, or west facing).
