A web campaign has scuttled a joint promotional deal launched last week by the Cincinnati Zoo and Botanical Garden and the Creation Museum, which promotes a strict interpretation of the biblical version of how life began.

Canopy walks at botanical gardens and arboretums are the hottest thing since children’s discovery gardens started appearing everywhere in the 90s. Kew’s new Rhizotron and Xstrata Treetop Walkway, named after the mining company that helped fund it and designed by the firm that did the London Eye, climbs 59 feet high into a canopy of chestnuts, oaks, and limes, and also takes a dip below ground to explore the subterranean world of tree roots. Another trend alert, at least in England: The design of the canopy walk is based on the Fibonacci Series.

Animal plant gardens have appeared at several zoos and botanical gardens. What seven year old can resist a planting of elephant ear, staghorn fern, lizard tail and the like? Glasshouse Works offers dozens of “zoomorphic plants,” including tapeworm grape and chicken gizzard plant. Eeewww! 

Some of the most spectacular treehouses you’ve ever seen, constructed around the world by a company called Baumraum.
