About this plant
Spiky plants that delight most people for their dramatic, generally rigid shapes, and the spectacular spikes of flowers that some of them produce. A surprising number of these can be grown out of doors in the UK. The largest form that can be grown in the garden is Yucca gloriosa and its variants. This can reach a height of two metres and is a major garden feature. There are a number of variegated ornamentals also available. There are some much more compact Yucca forms that are unlikely to exceed their allotted space, including Yucca aloifolia that stands around 60cm in height, though in flower this can tower to over 3 metres. Yucca flaccida, standing at around 1.2 metres, is an attractive option having a softer outline with curving rather than rigid foliage. A number of other species are suited to greenhouse culture, but can be put out in the summer. Other similar plants are the spiky Cordyline and the softer lines of Phormium.

Spring
Spring-Autumn · Indoors
Feed with houseplant food monthly
Give the plant a balanced houseplant feed monthly while in growth.
Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), with percentage values for each, choose one where the values are more or less equal.
Spring-Autumn · Indoors
Water to keep the soil moist
Water moderately from the period when growth starts (around April) until the early autumn (September).
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming 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 · Outdoors
Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
Spring - late · Planting
Divide when too large
When the plant is too large clumps may be divided into two or more pieces. Rhizomes can be cut, whilst small bulbs or offsets are detached. The new plants can be grown in a container or planted in the ground.
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 · Outdoors
Water lightly during dormancy
The soil should be kept just moist during the plant's rest period.
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
Minimum temperatures vary
Plant varieties within this genus have differing requirements for minimum temperature. It is best to look up your specific plant for guidance, and/or check the label.
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).
