The ZZ (Zamioculcas zamiifolia) is a semi-succulent native to the semi-arid regions of Eastern Africa. It is accustomed to long periods of dry conditions interspersed with bursts of generous rain. As such, the ZZ has evolved a rhizomous root system that holds on to as much water as it can absorb, as well as fleshy, moisture rich leaves. It is crucial to let your ZZ dry out between watering. This is a plant that thrives on neglect and is a great choice for frequent travelers and those who occasionally forget to water. The ZZ plant prefers bright indirect light but is very low light tolerant.
Placement: The ZZ is an ideal plant for the house or office. The species requires little attention and does well in almost any type of container. Indirect bright light is ideal for a ZZ, yet they are also content in low light situations, and do fine in direct light, making it a versatile and near fool proof indoor plant.
ZZs are one of the hardiest plants in nature, can be propagated from a single leaf.
The most common issue for a ZZ is over watering. A yellowing ZZ is often a sign it is getting too much water and the rhizomes may be rotting. Do not allow the soil to remain damp, it is important to let the soil dry out completely between waterings. Err on the side of too dry rather than too wet.
If the leaves are wrinkling and the plant is clearly dehydrated then saturate the soil, place the plant in bright, indirect light, and leave it alone for a few days. The leaves should plump back up shortly. Leaves that have already incurred damage may die off, but this does not mean the plant is dying, nor is it necessarily an indicator that the plant needs more water.
ZZs do best when not overly tended, but, as with any plant, it is a good idea to check in occasionally. Gently wipe down the leaves with a damp cloth when the plant appears dusty or dirty and periodically check for pests. Once you get to know your plant a bit, you should start to get a feel for when it is happy or in need of assistance.
