Plant family
Hoyas & relatives — Apocynaceae
326 species across 21 genera in the Growli library
The dogbane family gives the houseplant world the wax plants (hoya), string-of-hearts (ceropegia), dischidia and the desert-rose (adenium) — many of them trailing, waxy-leaved and grown as much for their fragrant, geometric flowers as their foliage.

Hoyas & relatives — frequently asked questions
Are hoyas & relatives toxic to cats and dogs?
Most hoyas & relatives are pet-safe. Of the 326 hoyas & relatives we cover, 217 are non-toxic on the ASPCA list and 109 carry a toxic or mildly-toxic rating. Even in a mostly-safe family, confirm the individual species before trusting it around pets.
How much light do hoyas & relatives need?
Most hoyas & relatives want bright, indirect light — 251 of the 326 in our library do best there. If yours stretches toward the window or loses its variegation it needs more light; scorched or bleached leaves mean it is getting too much.
Are hoyas & relatives easy to care for?
Hoyas & relatives are moderate to grow: the one real requirement is a genuinely bright spot out of harsh midday sun. Get the light right and most of the rest of their care follows.
What is the Apocynaceae family?
The Apocynaceae family — the hoyas & relatives — groups 326 species across 21 genera in the Growli library, most prominently Hoya, Asclepias, Huernia. Members share a broadly similar light, water and soil pattern, which is why it pays to learn the family before the individual plant.
