Chelsea Physic Garden

In case you needed a little secret hideout I can recommend the Chelsea Physic Garden. Spent a few hours there, truly lovely. It's London's oldest botanic garden, founded in1673.

Some of the flowers and leaves are both edible and decorative. Some gardeners appear to grow them in order to attract pollinating insects such as bees, others may find use in cosmetics and soaps. Some even feature anti-inflammatory and anti-viral properties.
