18 succulents and cacti
The catalogue has three shapes for plants that store water: the spiky rosette, the bushy succulent and the string of beads. The number to read here is the coldest night each one tolerates — that is what decides whether it can stay on the balcony in winter.
In the table, watering runs from 7 to 35 days at medium light; 2 of the 18 want humid air.
