 Showy Milkweed 
(Asclepias speciosa )

Monarch caterpillar host plant.

This perennial has large, oval, blue-green leaves and spherical clusters of rose-colored flowers. The flowers occur at the top of the stem and on stalks from leaf axils and bloom May to September.

Growing Conditions: Shade intolerant, needs sunlight, medium water use, moist soil

 Baldwin's ironweed
(Vernonia baldwinii)

Grows under a variety of conditions; spreads via rhizomes.

Western ironweed’s 3-5 ft. stems occur singly or in clumps, and are stout and hairy. Wide clusters of vibrant, red-violet flowers form at the ends of short branches near the top of the plant. Because the flowers are all of the disk variety, the 6 in. wide flower cluster has a fuzzy appearance. Long, lance-shaped leaves line the stems.

This plant aggressively colonizes by rhizomes once established so place accordingly. Its bloom period lasts until frost.

 Button eryngo
(Eryngium yuccifolium)

Can be aggressive self-seeder.

Scattered along the stiff, upright stem of this unusual perennial are tough, blue-green, yucca-like, parallel-veined leaves. Smooth, rigid stem bearing thistle-like flower heads made up of small greenish-white florets mingled with pointed bracts. The individual, greenish-white flowers cluster into unique, globular heads. These occur on branch ends atop the 6 ft. plant.

Their spiny leaves make walking through clumps of these plants difficult, and also make them unpalatable to grazing livestock. They were once credited with a variety of curative powers. Their flower heads develop a bluish cast with maturity.

 Compassplant
(Silphium laciniatum)

Drought tolerant. Looks similar to sunflower and attracts numerous pollinators.

Compassplant is a tall, coarse, sunflower-like perennial, growing 3-12 ft. high. Deeply cut, hairy leaves, up to 2 ft. in length, usually orient themselves north and south to avoid the heat of the noonday sun. Scattered along the top half of the stout, sticky stem are 2-5 in. wide, yellow, radiate flowers. A tall plant bearing yellow flower heads with large, hairy-edged, green bracts; stem exudes resinous sap

Compass Plant is one of a group of tall, mostly prairie sunflowers, some with very large leaves. The common name refers to the plants deeply incised leaves, which tend to be oriented in a north-south direction. The hardened sap of this plant can be chewed like gum. Rosinweed (S. integrifolium) has opposite, very rough, stalkless, untoothed or slightly toothed leaves and is 2-5 (60-150 cm) tall. Cup Plant (S. perfoliatum) has opposite leaves that envelop its square stem, each leaf forming a cup around it. Prairie Dock (S. terebinthinaceum) has large, ovate or heart-shaped, basal leaves to 2 (60 cm) long; the sparsely leaved flower stalk sometimes reaches a height of nearly 10 (3 m).

 Dakota mock vervain
(Glandularia bipinnatifida)

Long bloomer, with consistent blooms from summer through fall.

Gently rounded clusters of bilaterally symmetrical pink, lavender, or purple flowers bloom atop stems with highly divided leaves. The Spanish name, Moradilla, comes from morado (“purple”) and means “little purple one.” This plant often forms brilliant displays of pink or light purple, covering acres of ground. It is a variable complex, with some plants tall and pink-flowered, others more matted and with lavender or purple flowers; the two forms are usually found in separate areas. The genus Glandularia is closely related to Verbena, differing conspicuously in its round-topped clusters of showy flowers; in some references, this species is listed as Verbena ambrosifolia.

This species is a member of the verbena family (family Verbenaceae), which includes about 75 genera and 3,000 species of herbs, shrubs, and trees, mostly of tropical and warm temperate regions. Among them, teak is a highly prized furniture wood, and Vervain, Lantana, Lippia or Frog Fruit are grown as ornamentals.

 Gray goldenrod
(Solidago nemoralis)

Tolerates poor and dry soils. Shorter than most other goldenrod species.

Slender-stemmed plant, 1 1/2 to 2 ft. tall. Thin, coarsly-toothed leaves. Flowers occur on the upper side of hairy stalks which arch out and downward creating a vase-shaped flower cluster. Clumps of slender, gray-downy stems produce terminal, one-sided, yellow plumes that gives the perennial a vase-shaped appearance. A small goldenrod, this plant seldom reaches 2 ft. in height.

Prairie Goldenrod attracts butterflies. Individual plants bloom at various times, thus extending the flowering season.

 White crownbeard
(Verbesina virginica)

Biennial plant. Does best when allowed to naturalize.

This easy-to-grow Verbesina lends stately, dark green leaves and white, autumn flowers to the dappled shade found at the edges of woodlands, where it can form sizable colonies with its spreading rhizomes. Each stem has soft, fleshy green flanges running longitudinally down its length. When winter weather brings ice, the stems exude water that freezes into fascinating shapes, hence its common name Frostweed. This plant is best suited for naturalizing rather than formal landscapes.

The ice crystals formed on the stems of this and other plant species have been given many names - among them: ice ribbons, ice flowers, ice fringes, ice fingers, ice filaments, ice leaves, frost flowers, frost ribbons, frost freaks, frost beards, frost castles (Forrest M. Mims III http://www.forrestmims.org/gallery.html), crystallofolia (coined by Bob Harms at The University of Texas), rabbit ice and rabbit butter.
