It may still be too hot and humid to think about digging planting holes, but fall is right around the corner! Now is a great time to sit in the cool air conditioning and start planning what new plants you’ll add to your garden in the next few months as the temperatures start cooling off. Hopefully by the end of this post, Blue Star (Amsonia) will be on that list.

The Amsonia genus contains multiple species suitable for NC Piedmont gardens. All feature multi-season interest as well as durability for our unpredictable weather. It is the epitome of a low-maintenance plant while also having a naturally tidy habit and reinvigorating the landscape with its lovely golden color just as summer perennials are winding down for the year. What’s more, pollinators adore the blossoms, deer are unlikely to browse it, and it is extremely simple to propagate!
Botanical Overview
Blue Star is in the dogbane or Apocynaceae family (also home to milkweeds), and like many of the members of this family, it has a milky latex sap. Eastern Bluestar (Amsonia tabernaemontana) is native to the central and southern US; meanwhile, other species like Amsonia hubrichtii and Amsonia ciliata are native to the central US.
Blue Star is a native herbaceous perennial; it dies back above the soil at frost and regrows from the crown in early spring. Clusters of light blue flowers bloom atop a 2-3′ mound of tidy rounded foliage in April to May. When the flowers die back, they reveal finely textured foliage that stays lush and green despite the heat and humidity of summer. Then, it is ready to steal the show again in late October and November when the weather cools.

Cultivation and Care
Blue Star holds an erect, mounded shape in well-drained soils and full sun to part shade conditions. While it prefers fertile soils with organic matter, it tolerates a variety of soils common in central NC. To encourage a tidy form, trim the plant back lightly after spring blooming.
Planting and Propagation
Like many herbaceous perennials, new Blue Star plants are best added to the garden in spring or fall, and watered regularly for the first several weeks until establishment. When trimming the plant back in spring, snip a few softwood stem tips and propagate the plant easily by rooting cuttings in well-drained potting soil.
A Few More Fall-Interest Natives

Figuring out how to garden when you have deer is already a challenge, so you may be wondering how it can be done using only native plants. But fear not; with a little planning and careful plant selection it can be done. If you are just beginning to transition to native plants, keep in mind that a ratio of 70% native to 30% non-native is an acceptable and reasonable goal.1 While non-native plants are generally unable to host caterpillar species that are a critical food source for baby birds, there are some deer-resistant selections that can provide nectar for pollinators, habitat for animals, and structure and beauty in the garden design.
Plan for Structure in the Garden
When designing a new garden bed, it can be helpful to start with shrubs or small trees, particularly evergreens, that will provide structure or “bones” for the garden.The evergreen native yaupon holly (Ilex vomitoria) can be a solid backdrop to your other native plants.2 It tolerates sun to shade, comes in dwarf forms, and sports bright red berries in fall through winter which provide food for songbirds and small mammals. Sweet pepperbush (Clethra alnifolia), sweetshrub (Calycanthus floridus), and beautyberry (Callicarpa americana) are native shrubs that are not evergreen but can offer structure and texture to the winter design, and attractive foliage, flowers and berries during the other seasons. All three thrive in full sun to part shade. Calycanthus has fragrant spring blooms and Clethra’s late summer white flowers are a magnet for pollinators. Callicarpa sports a multitude of small bright purple berries as a valuable winter food source for birds and mammals.

Some non-native options that are both hardy and striking include the evergreen tea olive (Osmanthus fragrans) and false holly (Osmanthus heterophyllus), with ‘Goshiki’ as a choice cultivar. Paperbush (Edgeworthia chrysantha) is not evergreen but has delightful fragrant blooms in the winter and is an underutilized deer resistant shrub with beautiful form with or without its leaves. All three thrive in full sun to part shade. For a lower growing shrub in a sunny garden, consider the evergreen creeping rosemary (Salvia rosmarinus ‘Prostratus’) which will happily cascade over a rock or retaining wall.
If your garden is on the shadier side, try the native evergreen anise tree (Illicium floridanum) or doghobble (Leocothoe fontanesiana). Illicium can grow to 10’ but is easily kept in bounds by pruning. It also comes in numerous cultivars with a variety of flower colors and size ranges including dwarf forms. Leucothoe boasts showy, fragrant white flowers in spring.

A non-native choice for the shadier garden might include the Japanese plum-yew (Cephalotaxus harringtonia).‘Duke Gardens’ is a local cultivar noted for its compact shape.
Fill in the Garden with Perennials
Once you have anchored your garden design with some shrubs or small trees, it’s time to fill in with perennials. Many perennials can also provide structure and texture throughout the winter when you recognize the importance of leaving plants in the fall to provide winter habitat and food for animals. Hollow stems become nesting sites for solitary bees, and dried seed heads provide food for birds.
Choose Keystone Species
Significant deer pressure does narrow the palette but there are still many good plant options. A good place to start is to consider keystone species–plants that support the highest diversity and number of caterpillars. Goldenrods (Solidago spp.) are high on this list. If your garden is small consider some of the more well-mannered species such as sweet goldenrod (Solidago odora), white goldenrod (Solidago bicolor), or slender goldenrod (Solidago erecta). Most goldenrods bloom in the fall but using several different varieties can offer a spectrum of bloom time, shape, and color throughout the fall.3

Both offer colorful fall blooms to the landscape. (Image credit: Fritz Flohr Reynolds CC-BY-SA 2.0 ; Drew Avery CC BY 2.0)
Asters are also considered a keystone species. Asters may not be entirely deer resistant, especially under high deer pressure, but they tend to be so vigorous and bloom so late that deer browse is more like an early pruning and they will still often have a fine flower display in the fall. Consider incorporating aromatic aster (Symphyotrichum oblongifolium), New England aster (Symphyotrichum novae-angliae) or blue wood aster (Symphyotrichum cordifolium) to support specialized bees, caterpillars, songbirds and small mammals.
Plant Flowers with a Purpose
Flowers attract pollinators and add beauty. Many deer resistant natives are also great pollinator plants. Any of the mountain mints (Pycnanthemum spp.), will be swarming with hundreds of tiny pollinators throughout their bloom season, along with fragrant minty foliage. Blunt mountain mint (Pycnanthemum muticum) keeps evergreen through the winter, rising to several feet in the summer when it blooms. It can spread but is easy to pull up and share extra plants. Narrowleaf mountain mint (Pycnanthemum tenuifolium), has fine foliage and is more clumping. Hoary mountain mint (Pycnanthemum incanum) has silvery white foliage and fragrant leaves, but also likes to have some space and may be better for larger gardens. The mountain mints will tolerate partial shade.4
Boneset and thoroughwort (Eupatorium spp.) are underutilized native pollinator plants with excellent deer resistance. They have white flowers in summer and fall that attract bees and butterflies. Common boneset (Eupatorium perfoliatum) likes wet soils and will spread to form colonies. Roundleaf thoroughwort (Eupatorium rotundifolium) can tolerate both wet and dry conditions. Foxglove beardtongue (Penstemon digitalis) has showy white flowers in spring and its evergreen rosettes persist throughout the winter. An interesting and lesser-known plant that also has evergreen foliage in the winter is rattlesnake master (Eryngium yuccifolium), identifiable by its funky white ball-shaped flowers. Anise hyssop (Agastache foeniculum) is another key pollinator plant that has excellent deer resistance due to its licorice scent.

The beebalms (Monarda spp) seem to be less reliably deer resistant but are worth trying for their sheer flower power. Spotted beebalm (Monarda punctata) is an unusual species that seems to have somewhat higher deer resistance. It is a less aggressive spreader, and supports moths, butterflies, bees, hummingbirds, and several moth larvae.
(Left to right) Eastern bluestar‘s (Amsonia tabernaemontana) pale blue star-shaped flowers are attractive to beneficial insects but not to deer. These plants also provide fall color, as pictured here with the bright yellow leaves of the Arkansas bluestar (Amsonia hubrichtii).

A must-have in the deer resistant native garden are the bluestars (Amsonia spp.). Eastern bluestar (Amsonia tabernaemontana) has delightful blue flowers in the spring and can grow to shrub-like sizes. Similarly Arkansas bluestar (Amsonia hubrichtii) can get quite large with fine textured foliage that turns dazzlingly yellow in the fall. Both species do well in full sun but can tolerate part shade.
Russian sage (Salvia yangii) is not native but attracts bees, butterflies and hummingbirds and sports showy blue flowers spring through fall. It tolerates drought and is highly deer resistant.
Add Native Grasses to Your Landscape
Don’t forget grasses (or ferns and sedges for the shady garden). Native grasses can also be excellent choices if you have full sun and deer. Pink muhly grass (Muhlenbergia capillaris) is a well-known grass with plumes of delicate pink in the fall. Little bluestem (Schizachyrium scoparium), splitbeard bluestem (Andropogon ternarius), and others can lend a prairie-like look in a more natural garden setting. Bottlebrush grass (Elymus hystrix) is a more shade-tolerant grass with a seed head that looks just like a bottle brush. These grass species stay beautiful throughout the winter and support butterfly and moth larvae.

For shady areas consider bottlebrush grass (Elymus hystrix). (Image credit: Jim Robbins CC BY-NC-ND 4.0); Hope Duckworth CC BY 4.0)
Ferns also tend to be deer resistant and are more shade tolerant, with many native and non-native varieties to choose from. Christmas fern (Polystichum acrostichoides) is an evergreen native fern that will slowly spread and naturalize. Southern shield fern (Thelypteris kunthii) is a deciduous native but tolerates a wide variety of conditions and will naturalize to form large colonies. Ostrich fern (Onoclea struthiopteris) has a more formal vase shape and will also spread readily in favorable conditions. The evergreen native Cherokee sedge (Carex cherokeensis) tolerates wet soils, shade, and deer.
