Zones 3-8 Height 24″, width 12-24″. Full sun and well-drained, moist to dry soil. This Aster blooms late, September through October, and provides much needed nectar for bees that are still gathering the energy stores they will require to survive the long winter. Asters also feed many butterflies, including the much beloved Monarch, which during this time of the year is preparing to make the long journey to it’s wintering grounds in Mexico. Aromatic Aster is easy to grow, and unlike many asters, requires no staking, developing a mounded form that is as welcome in the formal landscape as it is in a wildflower prairie.
Black-eyed Susan (Rudbeckia hirta) “Indian Summer”
One of the easiest to grow native forbs which provides long lasting color to your garden and landscape. Flowers with bright yellow petals with purplish-brown center disks bloom June through October attract butterflies and other pollinators. Provides seeds through the winter for birds.
Blue False Indigo (Baptisia australis)
Zones 4-9 Prefers full sun to light shade and moist to dry soil. Takes a few years to establish, but then becomes prominent in the landscape, growing up to 4 feet tall. Given some space and time, their blue-green foliage becomes a nice backdrop for summer-blooming perennials. Baptisia is sensitive to high pH, so if you have trouble with it, consider a soil amendment similar to what you would feed a holly or rhododendron.
Boneset (Eupatorium perfoliatum)
Zones 3-9 Height 24-36inches. Sun to part-sun, moist to wet soil. While unobtrusive on its own, Boneset, with it’s triangular foliage and dainty, doily-like blooms blend well with other colors and textures in your flower garden. Very easy to grow, all members of this genus are valuable sources late summer nectar.
Butterfly Weed (Asclepias tuberosa)
Zones 3-9; Height 1-3 feet, width 12-18 inches. Full to part sun in well-drained soil. I’d just like to say outright that this flower is best planted in the fall. They are somewhat difficult to establish even then, but almost impossible to transplant successfully in spring, unless it’s before they break dormancy. The gorgeous orange blooms and lovely foliage are well worth the effort, however! Which explains why it remains a popular plant in garden centers. All members of the Asclepias genus are essential to the survival of Monarch butterflies. They are the only plants that the caterpillars will feed on.
Cinnamon Fern (Osmunda cinnamomea)

Creeping phlox is a woodland plant and prefers mostly shady spots.
