Enjoy it as a long-lasting flower: the colour lasts months, then the plant passes on to its pups.

Care

Light

Bright indirect light; no direct sun.

Water

Keep a little water in the central cup (changed every week or two) and the compost just moist; use rainwater or filtered water.

Soil

Small pot of free-draining bark-based or orchid compost.

Pruning

Cut off the bract once it fades. The mother rosette flowers only once and slowly dies.

Feeding

A very dilute feed occasionally in summer is enough.

Propagation

Pups form at the base after flowering; separate them when they are about a third of the mother's size and pot individually.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.
