Plant Family

 was added in the 2.0.0 update, and is located in the Plants section. It is very similar to the Plant upgrade system in Plants vs. Zombies 2. This lets the player increases the stats of their plants in a family. Each time the player upgrades a plant in a family, it will give the plant family an upgrade that has a random stat increased for a random amount. Each family can only choose 1 upgrade. The player is able to upgrade their plants in that family for free 3 times a day. If they want to upgrade furthermore, it will cost gems for every upgrade after that. The player can also pay 100 gems to unlock a new upgrade slot, yet the upgrades in this slot are more powerful. Getting more plants in a family will upgrade the level of that family, which will increase later upgrades' power.
