Fruits, vegetables and herbs
Growing plants you can put on the table can be very fun and rewarding. Look for varieties of food crops that will be fun and successful to work with, as well as some that may be an adventure.
Small fruits
Berries and grapes are ideally suited to many of Idaho’s growing areas. Regardless of where you live in the state, there are small fruits that you can grow successfully. As with all other crops, however, success largely depends on selecting varieties that are well adapted to your climate and soils.
Arbutus to grape
Arbutus
Also called the strawberry tree, arbutus grows an interesting small fruit that is edible and enjoyed by many. It requires well-drained acidic soil and is only somewhat cold hardy, so make sure you know your hardiness zone and soil before you consider this plant.
