• Greenhouse tickets are cash only, in Czech crowns at the ticket office, with no cards or euros accepted
• No scooters or ball games: bikes, scooters, skates and balls are banned and the lawns are off limits, so plan a slow wander, not a run-around
• Greenhouses close earlier than the garden, between 3pm and 4:30pm depending on the season, so head inside first

A 3.5-hectare garden run by Charles University's Faculty of Science. The greenhouses hold tropical and subtropical plants, including the national cactus and South African succulent collections, plus palms and cycads over 130 years old.

Outside, kids can spot a ginkgo grown like a giant bonsai, one of the first dawn redwoods planted in Europe, and a Central European flora collection started in 1904.
