Crops (Harvest Moon: Back to Nature)

You can purchase crops from Jeff at the supermarket, where stock changes depending on the season. Won also sells seeds seasonally at the inn. Seeds fall in a 3x3 square around you, covering nine squares in total. Crops don't need to be watered on rainy days and can be destroyed by natural disasters. The only flowers you can sell are Magic Red Flowers which grow randomly from Magic Red Flowers.

Grass seeds are sold at the Supermarket from Spring to Fall for 500G. Grass does not have to be watered, grows in 12 days, and regrows in 10 days. Once grown, it can be cut and is automatically sent to the Silo as Fodder, which is used to feed Cows and Sheep. Grass remains dormant in Winter, but will grow again at the beginning of Spring. Orange Cup flowers can be bought from Won's Shop year-round for 1000g. They will only grow in the Hothouse, and require 9 days to bloom (non-renewable).

Foraging
There are also seasonal wild herbs that grow naturally in Mother's Hill that you can forage. They spawn daily and can be sold or used as gifts. Several flowers also bloom in the plain of Mother's Hill.
