I wrote the first review about my disappointment. I revisited the garden two months later and found it much improved. I learned that the garden was completely flooded and suffering from severe infestations earlier in the year. I fully expect continued improvement, and I plan to visit in 2011.
On 7-1-10, the rose garden was in deplorable condition. Looks like no attempt at pest or fungus control. Many plants stripped bare. Few blooms accept for some measly knock out roses. A big disappointment if that's what you're visiting for.
