Urn plant

Sun

Bright indirect light indoors; filtered light or partial shade outdoors. Avoid strong afternoon sun, which can scorch the leaves.

Water

Water the potting mix when its surface has dried, then let it drain completely. Keep some clean water in the central leaf cup during warm growing conditions, refreshing it regularly; use rainwater where tap water is hard.

Soil

A loose, airy bromeliad mix, or orchid bark blended with peat-free potting mix and perlite. Good drainage matters more than rich soil.

Height

1-3 ft (0.3-0.9 m), including the flower head

Spread

1-2 ft (0.3-0.6 m) per rosette; offset clumps eventually grow wider

Flowers

Usually summer in natural conditions, though indoor plants may flower at other times. Small blue-purple flowers emerge among pink bracts; the bracts can remain attractive for several months.

Foliage

Evergreen. Broad, arching, grey-green strap-shaped leaves with silvery crossbands, arranged in a water-holding rosette. Leaf margins usually have small sharp spines.

Growth

Slow to moderate; offsets usually take several years to reach flowering size.

Care needed

Northern hemisphere months. In Australia, shift them by six.

Growth rate

Slow

• Use a pot with drainage holes and keep the base of the rosette above the potting mix.
• Flush and refill the central cup weekly in warm conditions to remove stale water and debris.
• Let the potting mix partly dry between waterings; never leave the pot standing in a saucer of water.
• Feed monthly in spring and summer with a balanced liquid fertiliser at one-quarter strength, applied to the potting mix.
• Keep above 10°C (50°F) where possible, and reduce watering in cool, low-light conditions.

Pruning. Cut the flower stalk close to its base once the bracts turn brown, using clean secateurs. Remove dead outer leaves as they loosen, but leave a declining mother rosette attached while it supports developing offsets.

Spring

Check drainage and repot only if the container is crowded or the mix has broken down.

Spring

Begin light monthly feeding as growth resumes; separate sufficiently large offsets if wanted.

Early summer

Move indoor plants outside only when nights remain above 10°C (50°F), introducing them gradually to a sheltered, shaded position.

Summer

Refresh the leaf cup weekly and check outdoor plants for mosquito larvae and scale insects.

Autumn

Bring container plants indoors before nights become cold; stop routine feeding as growth slows.

Winter

Provide bright indirect light, water the mix sparingly and avoid leaving cold, stagnant water in the leaf cup.

• Use a single plant in a simple container to show the symmetrical rosette and silver leaf markings.
• Group beneath palms or other high-canopy plants in frost-free gardens for contrasting leaf shapes.
• Place in a shaded courtyard alongside ferns and cast-iron plants for layered evergreen foliage.
• Use as a seasonal patio accent in colder climates, moving it indoors for winter.

Garden styles it suits: Modern tropical, Architectural minimal, Modern courtyard, Tropical, Small-space and Brazilian tropical modernism.

Plant it with: Cast-iron plant, Bird's nest fern, Parlour palm, Moth orchid and Chinese evergreen.

Wildlife: The water-filled rosette can shelter small invertebrates and, in tropical settings, small frogs. Its value to local wildlife is limited in most temperate gardens, and outdoor cups can harbour mosquito larvae.

• Root or crown rot: usually follows waterlogged mix, buried leaf bases or cold, wet conditions. Improve drainage, reduce watering and remove badly rotted tissue; save healthy offsets if the mother plant is lost.
• Mealybugs and scale insects: inspect leaf bases and undersides regularly. Wipe off small infestations and use an insecticidal soap labelled for indoor ornamentals if needed, testing a small area first.
• Brown, bleached patches: strong direct sun can scorch leaves. Move to filtered light; damaged patches will not recover.
• Mosquito larvae in outdoor leaf cups: flush the cup thoroughly every week rather than allowing water to stagnate.

Not known to be toxic to cats, dogs, horses or people. The leaf-edge spines can scratch skin or mouths, and chewing plant material may cause mild stomach upset.

• Amazonian zebra plant (Aechmea chantinii)

  Usually has stronger, more sharply defined pale bands on darker leaves and a branched flower head with orange-red bracts, rather than the compact pink head of urn plant.

• Queen's tears (Billbergia nutans)

  Has narrower leaves in slender, clustered rosettes and loose, nodding flower sprays rather than a broad urn-shaped rosette with a dense upright flower head.

Aechmea comes from a Greek word for a spear point, referring to pointed flower structures, while fasciata means banded and describes the leaf markings; urn plant refers to the water-holding rosette.

Propagation. Separate basal offsets in spring or early summer when they are about one-third to one-half the size of the mother rosette, preferably with roots of their own. Cut cleanly at the attachment point and pot into an airy mix, keeping the young plants warm and out of direct sun.
