Botanical Gardens
A botanical garden is a plant collection kept for science, conservation and public education — which is why it can show you plants no nursery will ever sell you. These guides cover what is actually growing at the world’s great collections and, more usefully, what any of it means for your own plot. Expect glasshouse collections, national seed and living-collection work, heritage trees, and the plant families each garden specialises in. Some of what you see is genuinely uncopyable at home: a plant held alive in a field gene bank because its seed cannot be dried and frozen is an institutional job, not a windowsill one. We say so when that is the case. Start with Kew for breadth, Lalbagh for the Indian heritage collections, or the full list of famous gardens.
