ZZ plant

ZamioculcasAraceae
Also: Zamioculcas, Zanzibar gem
AT A GLANCE
Bright indirect light Water: little H1babove 10 °C 45–90 cm tall · 40–60 cm wide In a pot: yes

As with snake plant, this genus fails from overwatering far more often than underwatering — when unsure, wait another week.

Care

Light

Exceptionally tolerant of dim rooms and artificial light, though grows faster in brighter conditions.

Water

Stores water in its rhizomes; allow compost to dry out fully between waterings, water even less in winter.

Soil

Free-draining, gritty houseplant compost.

Pruning

Remove any yellowing stems at the base; otherwise minimal.

Feeding

Two weak feeds across the summer is all it asks. This plant stores its own reserves in the rhizome and is far more often killed by generosity — with water or fertiliser — than by neglect.

Propagation

Divide the rhizomes at repotting. Leaf cuttings do work: a single leaflet pressed into compost eventually makes a small tuber, but it takes the better part of a year, so division is the practical route.

Month by month

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