If you don't come for the plants and trees, at least check out the decor in their market. This is a fantastic place to come for Christmas, when they have themed areas with ornaments, baubles, garlands, anything you can think of. The decorating staff here does a superb job, and it inspires the imagination as well as your Visa/ Mastercard.
They also have a section full of tasty food like dips, spices, baking mixes, roasted nuts, and then there are the kitchen decorations to go with them. The plants are pretty competitively priced, and they have a good selection. The staff is friendly and has good advice on their nursery inventory. I go here whenever I get a chance. I also usually drag friends with me who then want to come back. Good times.
