DESCRIPTION
Northern Sea Oats
Chasmanthium latifolium

Drooping seed heads hang in clusters from slightly arching stems topping an upright clump of bamboo-like foliage. Green leaves turn copper in fall and the seed heads emerge green but turn purplish bronze by late summer then dry to a straw color. The more water it receives, the more tolerant it will be of intense sun, but it still prefers shade. Clumping grasses like this provide nest sites and winter cover for quail, sparrows and other wildlife. They also provide fall and winter seeds for a number of birds including cardinals, towhees, juncos, sparrows and finches.

    Choosing the Right Plants

    American Beauties Offer Solution Based Plant Collections to Help you Choose

    Quick Tips for Choosing Plants:

    • Planting a variety of native trees, shrubs, perennials and vines increases biodiversity and gives wildlife a source for food, cover and nesting
    • Choose a mixture of deciduous and evergreen trees so birds and other wildlife will always be able to find shelter
    • Plant trees and large shrubs where they will block winter winds from the house and shade it in summer, that will save energy and lower your carbon footprint
    • Try your best to buy plants that were grown locally, your independent garden center will be your best bet
    • Think about ultimate height and width of the plant you choose, make sure it will fit the space you have for it when it's reached maturity
    • Plant nectar plants in groups, to attract butterflies and other beneficial insects more easily
    • Ask for help if you need it. Most garden centers either have a landscape designer on staff or they can give you a reference of a designer that is adept at native plant wildlife gardening. There will be upfront costs but they are small when compared to having to redo a landscape that wasn't what you really wanted

    Choosing the right plants for your garden can seem like a daunting task but we’re here to help. Our horticulturists have spent a considerable amount of time researching and writing our beautiful, American Beauties plant tags to help you be successful.

While the “Benefits” section talks about the plants strong suits and how the plant will benefit wildlife. 

    A Special Note About Exposure

    Full sun: Prefers six or more hours of direct sunshine a day
    Partial shade: Thrives in three to six hours of daily sunshine
    Shade: Generally does well with less than three hours of sun per day. Having said that even shade loving plants will struggle in extremely deep shade.
