"A Grade-II listed site, the beautiful 19-acre Sheffield Botanical Gardens were established in 1836 and showcase more than 5,000 species of plants. This is a lovely spot for a stroll, especially in the spring and summer, when many of the plants are in full bloom. Highlights include the glasshouses, also Grade II-listed, with temperate plants from Australia, Asia, and South Africa; the Victorian Garden; and the Four Seasons Garden, which is colorful at any time of year."
