Cabbage seeds give birth to boys. You can buy one in the store under the Garden tab. They cost 1000 beads. You can plant it in your garden. After you plant it, you can leave it alone, give it fertilizer, or give it Mandrake Elixir. Fertilizer speeds up its process of growing so you can pick it sooner. Mandrake Elixir makes it give birth to twins. After your cabbage seed blooms, another cabbage seed will automatically be planted in your garden. This also applys to rose seeds (girls).
