Herbarium is an anthology of poems from over 50 contributors celebrating and exploring the contemporary resonances of medicinal plants and herbs. The volume was edited by James Wilkes, responding to a Wayward Plant initiative to plant and maintain a temporary Urban Physic Garden at 100 Union St, London.

The anthology was launched at the Garden in July 2011 with readings from contributing poets. Copies are now sold out, but the poems and videos of readings are available to view on the Garden website.
