Have you ever tasted a pummelo? If you have, you’ll want a crop of your own. This largest of all citrus fruits is a big, sweet grandmother to the more common grapefruit. It has a thick, soft skin that cradles segments of fleshy, sweet fruit with none of that grapefruit bitterness. It comes to us from Asia, and with one taste you’ll understand why the Chinese believe good things come to those who eat it. Plant a pummelo tree and bring prosperity to your backyard.
