Foster began in the nineteenth century and now holds palms, orchids, cycads, exceptional trees, and threatened tropical plants within a compact urban garden. The garden’s mature canopy records global plant exchange as well as horticultural beauty. Labels can lead from useful and ornamental plants to conservation stories, while nearby roads make the sense of enclosure surprisingly strong.
Pick up the current map and look for champion and heritage trees rather than following flowers alone. Some paths and roots are uneven, tropical fruit or branches may fall, and collections change with storms, pruning, and plant health.
