Shiny Smoliv in Pokémon Scarlet & Violet
Location
The orchards around Cortondo are a great place to isolate this encounter. Use a grass type encounter & sparkling power sandwich, and you'll see tons of Smolivs.
Evolution
Smoliv evolves into Dolliv at level 25, and Arboliva at level 35.
Arboliva has cool, new signature ability called Seed Sower which automatically triggers Grassy Terrain whenever it takes damage, boosting the power of Grass-type moves.
