As someone who loves both birds and plants this is one of my favorite places to go in Las Vegas.
On the plant front they have the best selection of seeds I've seen in town (not just Burpee, they also have Botanical Interests and local Sweet Tomato Test Garden), and a variety of already grown vegetables and herbs that beats home improvement stores any day. They also have ladybugs, mantids and red worms in stock more often than other nurseries.
On the bird front, I am in love with several of their cockatoos and macaws. Delilah and Cool Whip love attention, and a few of the macaws will dance and posture if they see you looking at them.
