Their backyard also includes a few more sentimental varieties, including a hibiscus bush my dad planted in honor of my grandpa (his dad), who loved Hawaii and hummingbirds. Coincidentally, hummingbirds also love hibiscus flowers, and the blooms have attracted dozens of hummingbirds to his garden. Because my dad loves bird-watching so much, I bought him a Bird Buddy Smart Bird Feeder, and now, he can see his feathered friends even more up close and personal.
