as far as i know these are my only options- Tangela/Tangrowth
- Chikorita/Bayleef/Meganium
- Sunkern/Sunflora
- Oddish/Gloom/Vileplume/Bellossom
- Bellsprout/Weepinbell/Victreebell
- Exeggcute/Exeggutor
- Hoppip/Skiploom/Jumpluff
- Bulbasaur/Ivysaur/Venusaur
- Celebi
some of which are not very easy to get
feel free to yell at me about how going Grass-only isn't a good idea because grass types are weak against flying AND bug AND ice AND poison and have NO type advantage over any of the gyms OR elite four
