Greenie Get the app About
Greenie, and how we write about plants.
An iPhone app that names a plant from a photo, checks its health and reminds you when to water. Plus free care guides for the plants people actually keep at home.
Who makes it
Greenie is made by one indie developer, Gonzalo Fuentes. Questions, corrections and ideas go straight to him at hi@gonzalofuentes.com.
- 01
Where the facts come from
Every care sheet is compiled from the sources listed at its foot: botanical gardens such as Kew and the Missouri Botanical Garden, the Royal Horticultural Society, and university extension services. Native ranges follow Kew's Plants of the World Online.
- 02
How each sheet is checked
Each value on a sheet (light, watering, temperature, humidity, soil pH, height, growth, pet safety) is checked against the cited sources in separate review passes. Where the sources disagree, the sheet follows the most authoritative one. The date of the last check is on every sheet.
- 03
What "Unconfirmed" means
If no source we trust confirms a value, the sheet still shows our best estimate but labels it Unconfirmed, so you know which numbers are firm and which are rough guides.
- 04
Pet safety
A plant is marked safe or toxic only when the ASPCA Animal Poison Control Center lists that species, or its whole genus. Otherwise it says Not confirmed, even when the plant is often called safe. If your pet ate a plant, call your vet or an animal poison hotline straight away.

Corrections
Spotted a mistake? Email us and we will check it against the sources and fix the sheet. The care guides are general advice for growing plants indoors, not a substitute for a vet or a local expert.
