What is your favorite non-starter Grass type?

My favourite Pokémon – period – is Vileplume.  I admit it’s purely a matter of sentimentality; there’s nothing particularly wonderful about her design.  I just like it.  I suppose I’ve always considered Vileplume the archetypal Grass Pokémon – calm and gentle, but filled with some of the most horrid disabling attacks and support abilities you can think of.  The choice of the Rafflesia arnoldii as a design base is quite appropriate – the flower is striking, even beautiful, but its stench is proverbial.
