National Museum of American History

The Heirloom Garden, surrounding the National Museum of American History, Behring Center, has a variety of plants that highlight the types that have been passed down from generation to generation.

Here are a few that are in bloom during the summer months.

Achillea x ‘Moonshine’ Achillea x ‘Moonshine’
Moonshine yarrow


What’s a new heirloom plant? Alan Bloom introduced this bright lemon yellow bloomer which is a cross between H. x ‘Taygeta’ and A. clypeolata in the 1950’s. This plant is very popular in American gardens today, and I expect that it might also be passed down from generations to come.
Anethum graveolens Anethum graveolens
Dill
Pre-1700


This herb has been used for many purposes since ancient times. Dill seeds were chewed to stay awake in church and that is how the Colonial nick name “meeting house seed” came to be. Other accounts were that the steeped leaves could relieve witches of their power. And if one were presented with dill during the Victorian Era, one might wonder whether or not the giver intended lust or goodwill. In addition to aromatic foliage and seeds that are used in to flavor foods, dill plants also produce graceful, yellow umbel—shaped flowers.
Asclepias tuberosa Asclepias tuberosa
Butterfly weed
1690


Native Americans introduced the "weed" to early settlers as a medicinal plant, and that is probably why this native prairie plant was named after Greek god of medicine Asclepios. Asclepias tuberosa is also called pleurisy root due its medicinal indications. John Bartram (father or American botany) first collected the plant for garden cultivation, and Robert Buist, author of The American Flower Garden Directory (1839), referred to butterfly weed as “one of our finest wildflowers”, particularly for dry places. Buist was probably the first to recommended butterfly weed for garden cultivation. Jefferson was also a fan of the plant. But if that isn’t enough reason to favor the plant, the orange flowers are striking and butterflies love them too.
Chrysanthemum (Leucanthemum) x superbum ‘Alaska’ Chrysanthemum (Leucanthemum) x superbum ‘Alaska’
Alaska Shasta daisy


Luther Burbank owned a nursery and seed catalog business to support his obsession with plant experimentation. Thanks to Mr. Burbank’s persistence, he introduced over 800 new plants including the Shasta daisy he named after the California mountain. C. ‘Alaska’ was offered in Burbank’s 1904 catalog at a very steep $0.75 a piece.

Delphinium x belladonna ‘Cliveden Beauty’ Delphinium x belladonna ‘Cliveden Beauty’
Delphinium
1931


In the early 1900’s, blue delphiniums were fashionably planted next to yellow flowers. The tall spires were said to be the “best of blue flowers for border use” (Blanchan, Neltje. 1913. The American Flower Garden). This sky-blue beauty blooms twice a year in the Heirloom Garden.

Digitalis purpurea Digitalis purpurea
Foxglove
Pre-1600


Do the flowers look like fingers in a glove? Was the word “fox” once pronounced “folk” as in little folk or fairies? Reportedly, the dainty bells could empower one to recover children taken by naughty fairies, and the flowers could also rid one’s life of witches. Apparently, there is no agreement on where the common name came from or on ancient remedies. However, today “Digitalis medicines are used to improve the strength and efficiency of the heart, or to control the rate and rhythm of the heartbeat” (mayoclinic.com, May, 25, 2006), and admirers will probably be in agreement that foxgloves are one of their favorite cottage garden flowers.
Echinacea purpurea Echinacea purpurea
Eastern purple coneflower
1699


Echinacea has been used for centuries to treat measles, mumps, arthritis, chicken pox, blood poisoning, scarlet fever, ulcers, colds, bladder and other infections. This coneflower is still believed to have strong antibiotic and immune stimulating properties, although lately some are contradicting these popular beliefs. According to historical garden research, purple coneflower was sent to England in1640 prior to the plant’s cultivation in American gardens.
Lychnis coronaria Lychnis coronaria
Rose campion


Jefferson grew rose campion at Shadwell in 1767, but this magenta beauty had already been cultivated in American gardens since 1596. The furry, silver foliage resembles lamb’s ear.
Nigella damascena Nigella damascena
Love-in-a-mist
Pre-1700


Cultivated in English gardens in the late 1500’s, Nigella is also an American cottage garden favorite. Soft-blue flowers dry to create papery puffs that are used in dried flower arrangements. The seeds are known as black onion seeds and are used in Indian and Middle Eastern breads, vegetables, and beans.
Tradescantia virginiana

Tradescantia virginiana
Virginia spiderwort
1629


This native has long been admired and medicinally used by Native Americans. In the early 1900’s, Virginia spiderwort was used mostly in the wild garden. By the mid 1900’s, the plant had gained favor in the eyes of horticultural authorities, and recommendations were made that it be used in the flower border. At one time, the plant was believed to be an antidote for spider bites.
