I got it you get wood + stone = dirt
Dirt + water = plant
stone + air = sand
sand + water = clay
clay + fire = clay pot
clay pot + plant = planter
planter + water = flower
hope that helped :)
I haven't gotten to the flower but the best i have done is plant which you go wood + stone to make dirt and then dirt + water to make plant but after that it just makes a tree
