Tea Time in the Conservatory at Matthaei

The tea shrub (Camellia sinensis) is blooming in the Temperate House of the conservatory at Matthaei Botanical Gardens (late September 2013). Note that tea blooms in the fall — after its growing season is finished and before the plant goes dormant.
A flowering tea plant---Camellia sinensis

The tea plant (Camelia sinensis) — the source of tea leaves used to make the drink — is a camellia.  But not all camellias are tea.  Different parts of this plant are used to make tea, including the leaves, the leaf buds, and  the twigs. The leaves (picked at various times), leaf buds, and twigs are all used to make various drink types such as black tea, white tea, green tea, etc.

We also will have tea plant (shrub) in the new Medicinal Garden which will begin next year sometime in the former Exhibit Garden area outside the Conservatory.  Tea has been used to prevent dental caries(decay), and the antioxidants in tea are being studied in the prevention of cancer and for other medical uses.

Tea is not winter hardy in Michigan, so we’ll have to bring it inside before cold weather sets in.

Visit Matthaei Botanical Gardens and the conservatory today!

One Hundred Years of Cherry Blossoms

The planting of cherry tree seedlings at Matthaei Botanical Gardens and in Nichols Arboretum commemorates Japan’s 1912 gift of cherry trees to America—and reveals two University of Michigan connections

The National Park Service, which runs the Cherry Blossom Festival in Washington, D.C., describes the cherry blossom as a symbol of the fleeting nature of human life that also “epitomizes the transformation of Japanese culture throughout the ages.”

In celebration of that symbolic power and of Japan’s 1912 gift of trees, Matthaei Botanical Gardens & Nichols Arboretum is planting nearly 30 cherry-tree seedlings at Matthaei and in the Arb near the Peony Garden. The seedlings, germinated at Arbor Day Farm in Nebraska from seeds donated by Japan, were later delivered to 23 arboreta and botanical gardens in 21 states. The Arb & Gardens is the sole Michigan recipient of seedlings.

The seeds came from groves in Tokyo and Nara in south-central Japan, reportedly from the same groves where the original 1912 cherry trees were grown, according to Woodrow Nelson, Vice President Marketing Communications for Arbor Day Foundation, which germinated the seeds last year. (The Japanese name is Prunus jamasakura Siebold ex. Kidzumi. In the west, this tree is usually referred to as Prunus serrulata var. spontanea (Maxim.) E.H. Wilson.)

Timing drove the decision to send seeds, according to Nelson. When it heard about the centennial promotions, “Japan wanted to make the gift during the 2012 Cherry Blossom Festival but didn’t have trees to send,” Nelson says, so they sent seeds instead.

The new trees not only provide a connection to the widely celebrated Washington plantings and the friendship with Japan that they represent, says Matthaei-Nichols Director Bob Grese, “they remind us of our strong cultural connections with the people of Japan both at the University and in Michigan.”

The cherry trees also enrich our collections of culturally significant plants, such as the Nichols Arboretum Peony Garden, the Julie Norris Post Collection of Ericaceous and Appalachian Plants, and the Centennial Shrub Collection in the Arb.

A National Event that Nearly Wasn’t
Today a pilgrimage to see the cherry trees in bloom is a bucket-list essential, with millions of visitors flocking to Washington each year to capture a lasting memory of an ephemeral flower. Yet it took 24 years of letter writing by Elizah Scidmore—an American writer, photographer, and geographer who had lived in Japan—to get the U.S. government to plant them in the first place. The original proposal to plant cherry trees in Washington was Elizah’s brainchild. Beginning in 1885, she embarked on her long letter-writing campaign to convince the U.S. government to plant cherry trees in the capital. Finally, in 1909, Scidmore’s letter to first lady Helen Taft bore fruit when Taft promised to make the trees a reality.

Unfortunately, when the first shipment of trees from Japan arrived the following year, a USDA inspection team, which included nematologist Nathan Cobb, discovered that the trees were infested with nematodes. The trees had to be destroyed.

In 1912 Japan sent new cherry trees that passed inspection, and several were planted around the Tidal Basin. Workmen continued planting trees there for the next seven years, but it wasn’t until 1954 that the National Cherry Blossom Festival officially began.

In a 1946 letter, Harlow Whittemore wrote to A.C. Marshall, Detroit Edison’s past president, “We have had inquiry recently from Tokyo with regard to the donation made some years ago . . . for a Japanese cherry collection given by the University alumni in that city.” Whittemore, a Professor in the University of Michigan Department of Landscape Architecture from 1914-1958 and then U-M Chairman of City Planning, envisioned “a great collection of flowering trees” donated by Michigan alumni, one of which is the magnificent weeping Higan cherry near the Alex Dow Field (pictured above). Today Arb visitors make their own yearly pilgrimage to see the nearly 60-year-old tree. In a few short years, new cherry blossoms will grace the Gardens and Arboretum, dazzling visitors with nature’s display of renewal and transformation.

Go Pink—and Blue
What does the U-M have to do with Japanese cherry trees? Turns out there are two Michigan connections—to the 1912 gift from Japan and to the idea of planting cherry trees in the United States. The first is Frieda Cobb Blanchard, daughter of Nathan Cobb, an inventor, scientist, accomplished artist, and “father of nematology.”

As a member of a United States Department of Agriculture inspection team, Cobb discovered the 1912 shipment of cherry trees to be infested with nematodes—small, often microscopic worms, many of which are parasitic. Because of the nematodes, the cherry trees had to be destroyed. Frieda, who was born in Australia, moved to Ann Arbor in 1916 and, while earning her doctorate in genetics from the U-M, was appointed assistant director of the Botanical Gardens at its location on Iroqouis Street. Blanchard lived in Ann Arbor until her death in 1977.

The other U-M connection is the Grand Rapids-born O. C. Simonds, the celebrated landscape architect who studied at U-M and who designed Nichols Arboretum. Simonds was a colleague and advisor of the noted plant explorer David Fairchild, an early promoter of Japanese cherry trees long before they became a fixture in American gardens. Fairchild’s efforts to promote the plant likely helped inspire an American passion for the flowering cherry tree.

Fine Early-September Birding at Nichols Arboretum

Birders---and just bird lovers, too---pay a visit to Nichols Arboretum for a spectacular late-summer show.

A birder from one of the local birding groups posted the following sightings, recorded on these dates:

Monday evening, Sept. 2, between 6:30-8 pm:
Mourning warbler


Sunday morning between 9:00 AM and 12:00 PM at the Arb:
Black-throated green warbler
