Stewartia malacodendron

The ornamental value of Stewartia malacodendron has been described by authors of gardening and botanical literature for at least 200 years. William Bartram in his Travels through North and South Carolina, Georgia, East and West Florida (1791) mentioned the plant several times. Near Savannah, Georgia, he wrote of “this ancient sublime forest,” which besides Stewartia malacodendron, included Cornus florida, Halesia, Aesculus pavia, Sambucus, and Callicarpa, among others.

Even then the forest was giving way to development, but conservation was not yet a concern. Bartram wrote that the forest was “frequently intersected with extensive avenues, vistas and green lawns, opening to extensive savannas and far distant Rice plantations,” and that it “agreeably employs the imagination, and captivates the senses by scenes of magnificence and grandeur.” [1]

One hundred and seventy three years after Bartram, Elizabeth Lawrence wrote of a special trip to see Stewartia malacodendron at the North Carolina coast. Her host Miss Kate took them, after many miles of driving, to some woods that looked “impenetrable,” but then “parted some sweetgum branches and walked into the underbrush as easily as if she had opened a door and entered a country parlor.” Ms. Lawrence had less grace than her host in that situation, and stumbled, grumbled, and lost a few hairpins along the way.

The indignities must have been worthwhile, because Ms. Lawrence recalled the visit ten years after the experience: Eventually, “she [Miss Kate] stopped on the edge of a deep ravine. At the bottom of it a sluggish stream, fed by an old spring, ran through a carpet of fern, and the slope between was covered with a thicket of stewartias. Standing there above them we looked down on the flowers, and that is the way they should be seen—from above, with light coming through many leaves before it reaches the ivory cups that seem to hold the sweet mystery of the woods.”

In June of 1964 Ms. Lawrence wondered whether “the place has been cut up into building lots, or whether a superhighway runs through the ravine.” She fondly remembered how she had, “looked down on those white flowers growing gently among the green leaves.” [2]

More recently Gil Nelson and Larry Mellichamp have favorably reviewed Stewartia malacodendron in their books.

Dr. Nelson: “The flowers are about three inches wide when fully expanded, making them appear inordinately large against the 2–4-inch leaves. The blossoms are composed of five crinkled petals that start out pure white but change to creamy or yellowish white by maturity. A mass of deep purplish or burgundy-red stamens decorates the center of the blossom, lending a regal air to the flower.” [3]

Dr. Mellichamp: “Silky camellia is one of the most wonderful year-round trees I have grown. It’s also one of the most difficult. […] In bloom, it’s breathtaking, with dozens of gorgeous white flowers well displayed on the sweeping leafy branches.” He suggests growing the plant in moist, well drained soil, and never letting it dry out until well established. [4]

The rewards must be worth any extra attention Stewartia malacodendron requires as it’s getting settled into your garden. Mike Dirr is reported to have said about the silky camellia, “It’s every gardeners dream plant, like the finest piece of art or sculpture.” [5]

Ageratina aromatica

Ageratina aromatica (Lesser Snakeroot)

Scientific name: Ageratina aromatica, syn. Eupatorium aromaticum

Common names: Small-leaved White Snakeroot, Wild-hoarhound, Lesser Snakeroot, Aromatic Eupatorium

Family: Asteraceae

Nativity: Eastern North America

Location: Sandhills Gamelands, Hoffman, NC

Date: October 23, 2016

Notes: Along with thousands of others in the 1800s, Nancy Hanks Lincoln died of “milk sickness” when she drank the milk from a cow that had eaten a close relative of this plant, white snakeroot (A. altissima). A. aromatica may or may not be less toxic than its famous relative, but it looks similar enough to avoid consuming it lest you make a mistake in identification.

The chemical involved is tremetol; you can be poisoned by having a large amount of it at once, or small amounts over a long period. Cows that have eaten the plants will begin to tremble, especially after any exertion, then die within a few days.

Having warned you, CRC World Dictionary of Medicinal and Poisonous Plants by Umberto Quattrocchi (pg.  122) lists several historic uses for A. aromatica, among them crushing the leaves to apply to bruises and sprains.
