Nursery contributed plant descriptions

A just plain wonderful native annual flower with large (4”) fluffy flowers that tickle your nose as you bend to inhale the sweet honey-like scent. Named for the straw colored bracts encasing the buds that are as intricately patterned as the etchings on Acoma pottery. Its branching habit produces many white flowers with cream centers in succession throughout midsummer and fall. A lovely cut flower too. Fertile, well-drained, alkaline soils best, with low water needs once established.
