Just came back from a quick vacation to Denver. While there I took in the Denver Botanical Garden and the Butterfly Pavillion in Westminster. Both were great, and I LOVED the Butterfly Pavillion. I highly recommend it to anyone! 1200+ butterflies flying around in a beautiful atrium. I would love to bring something like that to our area. We have a local nature perserve that has a butterfly house, but it's a small plastic greenhouse. Plus they only have local butterflies and moths.
I didn't realize that Denver was pretty close in garden zones as we are here. We are a 4/5 and they are a 5/6. So almost everything that was blooming here when I left was blooming there.
