Sacred Lily, Lily of China
Rohdea japonica 

This rare and highly-prized, tropical-looking, oriental native provides the appearance of an evergreen hosta. The 1' long x 2" wide, thick, dark green leaves form an upright vase-shaped clump to 2' wide in 10 years. Late in the season, the insignificant flowers produce short stalks of red berries that persist through the winter at the base of the plant. When used en masse, Rohdeas are a dynamite evergreen addition to the deep shade garden for a presence even in winter.

It is noted for its large shiny cabbage sized foliage.  It has dark rose pink 16” tall flowers in April and its dark green leaves which turn purplish-bronze in winter.   ‘Winterglut’ features large rosettes of leathery, glossy, toothed, rounded, dark green leaves (to 10” long by 8” wide) that are heart-shaped at the base. Leaves typically form a thick, slowly-spreading clump of foliage to 12” tall. ‘Winterglut’ has unique reddish fall and winter foliage color.   The common name is generally, simply Bergenia but it has been historically called Pigsqueak because of the noise produced by rubbing a leaf between your thumb and finger.

This is a rarely-sited native perennial plant that appears naturally in varied habitats ranging anywhere from moist to slightly dry black soil prairies, clay prairies, sand prairies, thickets, typical savannas, sandy savannas, and limestone glades. It has a stout central stem that is unbranched, except near the flower head. The alternate leaves tend to occur near the base of the plant, although a few smaller leaves occur along the upper portion of the stem. These leaves are long and strap-like, rather stiff in texture, and up to 2½' long and 2½" across. They are narrowly lanceolate, often curve downward, and have parallel venation. There are widely scattered, but stiff, teeth along the margins. The entire plant is bluish or greyish green and hairless.  Interesting fact, this is a very odd member of the Carrot family that resembles a yucca.

The red-tinted early spring foliage is easily identifiable in the perennial landscape.

Spurge
Euphorbia amygdaloides var. robbiae

This variety has dark, glossy evergreen leaves arranged in tight rosettes and produces yellow-green bracts in mid-spring and early summer. This plant is useful as an effective ground cover, as it spreads by root runners. Its drought tolerance also lends this plant to xeriscaping.  This Euphorbia will also tolerate full shade and coastal conditions. Care should be exercised when locating this plant as its sap may cause an allergic reaction in some people.  Ecologically this plant will attract pollinating insects such as bees that will feed on its nectar. Spurge is one of the best for using as a groundcover in milder winter regions. Plants form an evergreen spreading mound of deep green, leathery leaves held on bronzy-red stems. Clusters of greenish-yellow bracts are showy in late spring. Good candidate for problem areas and may be trimmed immediately after blooming, if desired.

Spurge
Euphorbia amygdaloides 'Purpurea' (E. a. rubra)

This is a highly desirable, purple variation of wood spurge goes through an interesting seasonal evolution of coloration. Its foliage starts out green in the Spring, then each sprig of new growth coming in with a wine-colored blossoms. In late March throughout April, it bursts into a profusion of lime green flower heads almost blotting out the foliage.  In Fall & Winter, the upper leaves and stems mature to a deep purple-ruby. The following Spring, the leaves become green again.  This particular wood spurge will give the best show in full sun in coastal areas with average to low water and well-drained soil. As it ages, the parent plant will self seed new plants to refresh itself.

Spurge
Euphorbia dulcis 'Chameleon'

An erect, rhizomatous perennial that grows a bit shorter than our other spurges.  It has the same oblong leaves with dusky leaves but these have a nice purple in the spring.  It does not wait for the fall to show off its colors.  It matures to a rich burgundy-purple and then a reddish tinge in autumn.  The stems are also purple.  The yellow showy bracts will appear in late spring and are usually lightly tinged with purple as well. The true flowers are yellowish-green and inconspicuous. Foliage provides interesting summer and fall accent. Milky sap can irritate skin and eyes and is mildly poisonous if ingested.  The more sun the deeper the foliage color.

Euphorbia palustris

This is a European native Euphorbia that is also most attractive in the fall when the the foliage turns bright orange and yellow. In the spring it forms bright radiating green, willow-like leaves on delicately branching stems. Then, in spring to mid-summer it puts on quite a show of large, umbel-like, chartreusy-yellow flower bracts. True to its name “palustris” meaning swamp-loving, it thrives in moist conditions, but tolerates some dryness, too. Perfect for the edge of a woodland garden, where deer are prevalent as it not attractive to deer in the least.  Remember, Euphorbias have a milky sap that can be irritating to skin and eyes so use caution when cutting back.

Swamp Sunflower
Helianthus angustifolius 

This is a narrow leaf sunflower that is naturally found along bogs and ponds in more than 20 states in the Union.  Here in the Mid Atlantic its significant blooms appear in October in a golden mass along our rivers and inlets surrounding the Chesapeake Bay.  It thrives in sandy banks and mesic areas in full to part shade.  It has thin dark leaves which are attractive but it is the fall blooming 2” golden flower that makes this an attractive native.  In the optimum environment, it is quite prolific.  In a typical perennial bed without the excessive moisture it is less aggressive but will adapt nicely.
