Grow 10 Zen Garden plants to full size.
The easiest way to get the achievement is to buy three Marigold sprouts for four consecutive days (three days would only produce nine) and tend them until they become fully grown Marigolds. You can also easily find plants in every level. To save money, buy one Marigold on the fourth day. Getting far in Survival: Endless can give you lots of sprouts as you progress.
- Greenfingers is from the phrase "green thumb," a name made for people who are skilled with plants and gardening.
- The icon of this achievement shows green thumbs in a flower pot.
- The player can buy presents, enabling them to get Greenfingers in a similar way as with Marigolds.
