The hat trick of plants for supporting wildlife. The leaves form ‘cups’ holding water for songbirds and insects to drink from. The flowers and seeds provide food for pollinators and songbirds. If left to naturalize, the plants form a tall hedge offering birds and insects refuge. Self sows easily and can overpower small gardens if not maintained.
