Plants are a creature type associated most heavily with green mana, lands, tokens, and +1/+1 counters. Plant decks tend to grow gradually before their harmless-looking vegetation turns into a legitimate battlefield problem.
Avenger of Zendikar produces a Plant for every land you control and then grows them through landfall, while Phylath provides a similar strategy. Greensleeves, Maro-Sorcerer can supplement the garden with Badger tokens as lands enter.
