Chelone glabra – White Turtlehead
Host Plant – Baltimore Checkerspot
Spikes of elegant white flowers top shiny green foliage in late summer and early fall. Grows best in moist meadows, stream banks, and swamps. Favorite breeding site for the Baltimore Checkerspot Butterfly.
Dalea purpurea – Purple Prairie Clover
Host Plant – Sulphurs
Tiny rose-purple flowers in cylindrical, head-like masses at ends of upright wiry stems.
This is one of the most widespread of the perennial Prairie Clovers, identifiable by their cone-like flower heads. An excellent range species, with high protein content, Purple Prairie Clover decreases in abundance with overgrazing. A midwestern white-flowering species, White Prairie Clover has elongated flower heads and is only 2 (60 cm) tall. A white-flowering southeastern coastal plain species, D. carnea var. albida, has conspicuous green bracts within the heads.
Eupatorium perfoliatum – Boneset
Growing in moist conditions, Eupatorium perfoliatum (Boneset) produces flat to roundish heads of white flowers. The stem is covered with long spreading hairs with leaves that are often joined at the base, appearing to surround the stem. Many different insect species are attracted to the flowers as the nectar is relatively easy to access.
Eutrochium purpureum – Purple Joe Pye Weed
Easily grown in average, medium moisture soils in full sun to part shade. Prefers moist, fertile, humusy soils which do not dry out. Cut plants to the ground in late winter. Best propagated by stem cuttings. This species generally grows … Read More
Liatris spicata – Dense Blazingstar
Easily grown in average, medium, well-drained soils in full sun. Somewhat tolerant of poor soils, but prefers moist, fertile ones and generally performs better in moist soils than most other species of Liatris. Intolerant of wet soils in winter. Tolerant of summer heat and humidity. May be grown from seed, but is slow to establish.
Noteworthy Characteristics
Blazing star (also commonly called dense blazing star or marsh blazing star) is a tall, upright, clump-forming perennial which is native to moist low grounds, meadows and marsh margins. In Missouri, it has only been found in Oregon County on the Arkansas border (Steyermark). It typically grows 2-4′ tall in cultivation, but can reach a height of 6′ in some parts of its native habitat. Features terminal spikes (6-12″ long) of sessile, rounded, fluffy, deep purple flower heads (each to 3/4″ across) appearing atop rigid, erect, leafy flower stalks. One or more stalks arise from a basal tuft of narrow, grass-like, medium green leaves (to 12″ long). Stem leaves gradually decrease in size toward the top. Blooms in summer. Liatris belongs to the aster family, with each flower head having only fluffy disk flowers (resembling “blazing stars”) and no ray flowers. The feathery flower heads of liatris give rise to another common name of gayfeather. See also L. spicata‘Kobold’ which is a popular compact cultivar that is less likely to need staking than the species.

Mimulus ringens – Monkeyflower
This perennial plant is 1-3′ tall, branching occasionally to frequently. The light green stems are glabrous and bluntly 4-angled, but they are not conspicuously winged. The opposite leaves are up to 4″ long and 1″ across; they are light to medium green, lanceolate or elliptic-oblanceolate in shape, glabrous, and serrated to sparingly serrated along their margins. The leaves are sessile or they clasp the stems; petioles are absent. Leaf bases are round to slightly cordate, while their tips are slender and pointed. Individual flowers develop from the leaf axils of the middle to upper stems. These flowers are about 1″ long, and they have two-lipped corollas that are usually pale blue-violet (less often pink or white).
Available May – Mid May 2015
Ruellia humilis – Wild Petunia
Host plant – Common Buckeye Butterfly
Wild petunia occurs in dryish soils in open woods, glades, prairies and fields throughout the State except for the far southeastern lowlands. Typically grows to 2′ tall. Features tubular, bell-shaped, petunia-like flowers (to 3″ long), each with five shallow rounded lobes. May to October bloom period. Lavender to lilac flowers appear singly or in clusters in the upper leaf axils. Oblong to lanceolate, olive green leaves to 4″ long. Leaves and stems are hairy. This plant in on threatened list in the state of Michigan.

Senna hebecarpa – Wild Senna
Host Plant – Sulphur, Clouded Sulphur, Orange Sulphur
Wild Senna is a versatile plant that we think deserves more recognition as a great choice for garden or restoration projects. Its lovely, bright yellow flowers bloom July-August, attracting many bees and butterflies. Autumn brings beautiful leaf colors and the formation of long black pods with seeds favored by larger birds like wild turkeys. A horizontal root system provides strength against winds, allowing the plant’s stately (4-6′) beauty to be appreciated even after the storm. Some gardeners use this sun-loving plant to form a hedge.
It is virtually indistinguishable from its relative, Maryland Senna (Senna marilandica) until the two species have ripe seeds. The Wild Senna will readily open its pod and the seeds will fall out, whereas the Maryland Senna seed pods will stay tightly closed. Other than this, it is very hard to tell the two species apart.
Solidago sphacelata – ‘Golden Fleece’ Dwarf Goldenrod
Another fantastic Mt. Cuba introduction. A stunning show of sprays of golden yellow flowers from mid-August through September. Semievergreen heart-shaped leaves. Truly an excellent groundcover and bee and butterfly charmer! Hairstreaks, sulphurs and skippers are particularly attracted to goldenrod. Monarchs visit it during their autumn migration.
Goldenrod Interesting Notes
Golden Fleece autumn goldenrod was discovered in 1985 as a spontaneous garden seedling in Eden, North Carolina. It was evaluated under diverse conditions at Mt. Cuba Center and determined to be a low-growing, compact form of the species suitable for use as an herbaceous perennial groundcover only reaching 18” tall. Multi-branched stems arise from basal rosettes of broadly rounded foliage and are covered with a profusion of golden-yellow floral spires from mid-September to October. It performs best in full sun with average moisture but is tolerant of a range of conditions from sunny and dry to partial shade. 'Golden Fleece' is hardy in zones 3-8. It won the Internationale Stauden-Union’s Award for an outstanding new plant in Switzerland in 1994. – Mt. Cuba Center
In many of the gardens I design, I use goldenrod to give late summer and fall gardens just the right autumnal color. Luckily for urban dwellers with limited gardening space, goldenrod also can be grown quite successfully in a container. Beautiful in the garden, goldenrod does double-duty as a long-lived cut flower. In Europe, where goldenrod has long been shown the appreciation it deserves, it is sold by the bunch, and gardening catalogs offer more cultivars than are available in the States.
Solidago sphacelata 'Golden Fleece' Growing and Maintenance Tips
Native to calcarous woodlands and rocky pastures from Virginia to Illinois south to Kentucky and Georgia. Prefers somewhat fertile, sandy, well-drained soils in full sun. Propagate by seed or division every 3-4 years. Cut back to encourage rebloom. Used in butterfly and wild gardens or as a groundcover or border perennial.
Spiraea tomentosa – Steeplebush
Pink spikes of flowers mid to late summer make Steeplebush a popular species. It grows best in moist acidic soils in full sun. Slow rhizomatous roots help this beautiful plant to spread.
Viburnum dentatum – Arrowwood Viburnum
Easily grown in average, medium, well-drained soil in full sun to part shade. Prune immediately after flowering since flower buds form in summer for the following year.
Noteworthy Characteristics
Arrowwood viburnum is an upright, rounded, multi-stemmed, deciduous shrub which typically matures to 6-10′ tall with a similar spread, but may reach a height of 15′ in optimum growing conditions. Non-fragrant white flowers in flat-topped corymbs (to 4″ diameter) appear in late spring. Flowers give way to blue-black, berry-like drupes which are quite attractive to birds and wildlife. Ovate, toothed, glossy dark green leaves (to 4″ long). Variable fall color ranges from drab yellow to attractive shades of orange and red. Although widespread in eastern North America, this native plant is only known to exist in the wild in Missouri on wooded slopes along the Salt River in Shelby County. Native Americans reportedly used the straight stems of this shrub for arrow shafts, hence the common name.
Problems
No serious insect or disease problems.
Zizia aurea – Golden Alexanders
Zizia aurea is one of those natives that every garden should have. It is fairly easy to grow and, although short-lived, will self-seed and persist in many sun/soil situations. Zizia is an important plant to a number of short-tongued insects that are able to easily reach the nectar in the small yellow flowers. Black Swallowtail caterpillars will feed on its leaves.
Golden Alexanders have a long bloom time, giving the garden/prairie some well-deserved early color for several weeks in late spring to early summer when many other plants have not yet flowered. Also called Golden Zizia, Golden Alexanders will tolerate a lot of shade but prefer full sun or light shade.
