Unique perennial of true tall grass prairies! Surpringly belongs to Carrot Familly (Apiaceae), but has unusual look – thicker, strap-like leaves, mostly concentrated in rosettes or at the base of the tall stems (leaves remind of Yucca). Round to oval, silver-white flower heads. The whole plant has charming silver-gray look.

This is great structural perennial, that starts the season with sharp looking rosettes, it’s full height reaches in summer. Flowers over a month, the whole flower head to seed head effect last for 2 months (then the seeds start to fall out). Looks very good both in flower borders, or naturalized in prairies, prairie style plantings, native plant gardens or pollinator gardens. It looks good with many prairie grasses (Andropogon, Eragrostis, Muhlenbergia, Panicum, Sorghastrum, Sporobolus, Stipa) and other prairie plants like Allium cernuum,asclepias tuberosa, Coreopsis, Echinacea palida, Echinacea purpurea, Gaura, Liatris, Penstemon digitalis (and it’s dark-leaved varieties like ‘Dark Towers‘ or ‘Husker Red‘), Ratibida, Rudbeckia etc.

We also highly recommend blue flowering perennial combos, because these look really chic Agastache ‘Black Adder‘, Agastache ‘ Blue Boa‘ and Salvia nemorosa ‘Caradonna‘ (the best i fit is cut back after first flower flush), probably hardy Geraniums with blue flowers would do great job too.

Dried seed heads were used as rattles by Native Americans, also tea made of it's root was suppose to be rattlesnake bite antidote.
