Offensively, although they are the only type that can super-effectively handle commonly-used Water/Ground Pokémon such as Quagsire, Grass types have problems in most other situations. The main problem Grass-type moves face is that nearly all of the few Pokémon they are advantageous against are also weak to moves of other types, hence making them seem dwarfed by the effectiveness of moves of other types. Other problems are that too manyPokémontypesresistthesemoves (including themselves) to rely on them as a main form of dealing damage, and most of them aren't very powerful. Even then, most of the powerful moves have severe drawbacks. Leaf Storm harshly lowers Special Attack, Wood Hammer causes recoil damage, Petal Dance causes confusion, Solar Beam requires charging up if intense sunlight is not present and Frenzy Plant requires a turn to recharge after being used. The majority of Grass types have very narrow movesets, often where the only damage-dealing level up moves are Grass-type and Normal-type moves (as seen in Pokémon such as Meganium, Cherrim and Sunflora). Another problem is that double resistances to Grass are extremely common, even more so than double weaknesses, and the Ability Sap Sipper, which several Pokémon have, negates Grass-type attacks, and even raises Attack whenever hit by one.
Defensively speaking, Grass types have both good and bad points. Whilst weak to the Ice type and Fire type—two very commonly used types offensively—the other weaknesses of the Grass types are rarely used offensively; furthermore, two of the types that specialise in moves that Grass types are weak to are hindered by their poor offensive stats. Also, most Grass types have a secondary type which eliminates their weaknesses to Poison- and Bug-type moves, which in turn makes Flying-type moves more of a threat. Furthermore, all of Grass's resistances are quite common.
On the other hand, Grass types' main problem is their weakness to five types — the most weaknesses of all types, tied with the Rock type. Also, in practice, Grass types' resistances are still of little use. Almost all Water types make use of Ice Beam, and most Electric types can learn Signal Beam, while several Rock types and Ground types can learn Fire-type moves. With a number of Grass types being half Poison-type, their resistance to Ground-type moves has been hindered. Given all of this, Grass types are difficult to switch into play.
Despite some of its defensive flaws, it is typical for Grass types to learn Leech Seed and Synthesis, among other disabling moves, like PoisonPowder, Sleep Powder and Stun Spore. This enables Grass-type Pokémon to provide support to the rest of their team, and can make them difficult to faint. In addition, a particular asset of this type is being the only one immune to Leech Seed.
As of Generation VI, Grass-type Pokémon are immune to spore and powder moves, such as Spore. Because of this, alongside their resistance to Grass-type moves and immunity to Leech Seed, they are good at defending against other Grass-types.
In Contests, Grass-type moves are typically Smart moves, but can also be any of the other four Contest types.
As of Generation VI, there are 86 Grass-type Pokémon or 11.7% of all Pokémon (counting forms and Mega Evolutions that change typing as different Pokémon), making it the fourth most common type.

Interacting with Grass-type
Users of Color Change will be changed into Grass-type after it is hit with a Grass-type move. Protean will change its user into Grass-type when it uses a Grass-type move. When a Pokémon with Multitype holds a Meadow Plate, it will become a Grass-type Pokémon. When a Pokémon with Imposter is sent out and its opposite opponent is Grass-type, it will transform into that Pokémon and turn into Grass-type.

Generation V introduced the most Grass-type Pokémon of any generation, with 21 (including Rotom's Mow form), and Generation VI introduced the fewest Grass-type Pokémon, with nine.
Generation I introduced the most Grass-type moves of any generation, with 10, and Generation II introduced the fewest Grass-type moves, with three.
The Grass type and/or Pokémon of the type have been referred to using the term "plant" instead on some occasions:
In the English Generation I games, the Gym guide in Cerulean Gym refers to Pokémon of the Grass type as "plant Pokémon". In the Japanese versions, he mentions the Grass type itself, calling it the "Plant type" (Japanese: しょくぶつタイプ).
