Exotic Vine Once Considered Ornamental, Now Invasive

Exotic Vine Once Considered Ornamental, Now Invasive

Recently I noticed what appeared to be an invasive vine in my garden.

The vine Celastrus orbiculatus, or Oriental bittersweet, had climbed up a lovely white birch tree, practically strangling it. [below]

I cut and pulled as much of the vine off the tree as I could. I was not able to reach the top of the tree, but I can now see the leaves, cut from their stem, drying up.

Oriental bittersweet came to the US in 1886 from Japan as an ornamental vine for the home landscape. That year it was first offered in the New York Kissena Nurseries catalog.

According to Peter del Tredici’s 2014 article “Untangling the twisted tale of oriental bittersweet” in Arnoldia magazine it was the Arnold Arboretum in Boston that popularised this vine for American gardens.

Today it is considered invasive here in the Northeast.

In the New Hampshire Landscape Association Newsletter horticulturist Michael Bald calls it a “most-alarming terrestrial plant species” in his article “Three Invasive Plant Species to Really Watch Out For.”

Climbers were coveted in the late nineteenth century Victorian garden.

Rochester, New York seed coompany owner James Vick (1818-1882) praised such vines in his catalog of 1874. He wrote, “The climbers furnish us with nature’s drapery, and nothing produced by art can equal their elegant grace. As the Lilies surpass in beauty all that wealth or power can procure, or man produce, so these tender Climbers surpass all the producing of the decorator’s skill.”

Vick included the native bittersweet, Celastrus scandens, in the section of his 1889 catalog called ‘Climbers.’

By 1893 imported bittersweet Celastrus orbiculatus was found in many gardens in the United States, according to del Tredici.

Michael Dirr writes in his useful reference book for gardeners Manual of Woody Landscape Plants that today Celastrus scandens has hybridized with C. orbiculatus and so can also be considered an invasive vine.

It may seem hard to imagine that what was once considered a desirable ornamental plant is anything but that for today’s garden.

Celastrus orbiculatus is only one among many exotics that have now become invasive.

Can you name others?

Late Nineteenth Century Gardens Included Perennials

Late nineteenth century gardens included perennials –

Last week I visited the Moffatt-Ladd House and Garden on Market Street in the seacoast city of Portsmouth, New Hampshire.

Portsmouth is home to several historic gardens in the downtown area. Because of its long tradition as an important early American seacoast city Portsmouth includes Colonial, Georgian, and Victorian styles of architecture and landscape.

In 1912 the National Society of the Colonial Dames acquired the Moffatt-Ladd House. Built in the late 1700s, the house once belonged to William Whipple, one of the signers of the Declaration of Independence.

The landscape includes an elaborate garden which, in its present form dates to the second half of the nineteenth century when Alexander Hamilton Ladd (1815-1900) owned the property.

Ladd kept a journal of what he planted in the garden. The journal, simply called Alexander H. Ladd Garden Book 1888-1895: A 19th Century View of Portsmouth was discovered only a few years ago and is now available for anyone to read. It provides a wonferful glimpse of American garden history.

In the book Ladd carefully lays out his work in the garden. At one point he planted 60,000 tulips.  Plants were his true love.

He also wrote about his beds and borders of perennials, which, by the late nineteenth century, had become a popular form of gardening, replacing the use of annuals. By the 1870s English garden celebrities writer William Robinson and landscape gardener Gertrude Jekyll were encouraging perennial borders.

Rochester, New York nurseryman George Ellwanger (1816-1906) wrote a book called The Garden’s Story in 1889. He  argued against both the stiff formal garden and carpet, or ribbon, beds. He noted that “the objectionable forms of gardening are being superseded by a more natural style–a revival of the old-fashioned hardy flower borders, masses of stately perennials.”

Today you can still see that garden fashion in the garden at the Moffatt-Ladd House in Portsmouth. Beds of stately perennials instead of the dreaded carpet beds and ribbon beds of annuals fill the garden. [below]

Though it was a very hot day when I visited, I enjoyed this reveal of garden history.

Thanks to all the volunteers who work in the garden to keep it in the style Ladd first laid out in the late nineteenth century.

Milwaukee Honored Alexander von Humboldt

Milwaukee honored Alexander von Humboldt. The city named both a street and park after the nineteenth century German scientist.

I was born and raised in Milwaukee.

The city played an important role in making the German plant explorer, scientist, and writer Alexander von Humboldt (1769-1859) more familiar to Americans.

Humboldt Boulevard, a street on the east side of Milwaukee, croses Fratney Street where my brother and his family lived for many years.

Humboldt Boulevard was named after Alexander von Humboldt.

Humboldt Park in the Bay View area of south-east Milwaukee, not far from Lake Michigan, was given its name in 1900, also to honor the German scientist.

Today the Milwaukee County Parks website says this about the 45-acre Humboldt Park: “Home of Milwaukee’s Craft Beer Garden, Humboldt Park also features a bandshell, ball fields and courts, a lagoon for fishing and ice skating, plenty of pathways, and community events all year long.”

Here is photo of the park from the early twentieth century. [below]

British author Andrea Wulf wrote a book about Humboldt called  The Invention of Nature: Alexander Von Humboldt’s New World . The book is a joy to read because you see the impact of Humboldt on ecology, a field he pioneered. Wulf says, “His name was a household name around the country after he published his book called Cosmos.”

Cosmos appeared in five volumes from 1845 to 1862.

After 1850 Milwaukee was home to many German immigrants.  They developed a beer industry that gave the city several breweries including Pabst, which became the largest brewery in the world by the 1890s.

Wulf writes that “The U.S. Secretary of War, John B. Floyd, sent Humboldt nine American maps that showed all the different towns, counties, mountains, and rivers that were named after him.”

So when, so many years ago, I rode the bus on Humboldt Boulevard, I was honoring Alexander von Humboldt, the German scientist. I never knew that til now.

Plant Language Shapes Reality

Plant language shapes reality – 

I just can’t say enough about Andrea Wulf’s book on Alexander Von Humboldt (1769-1859) called  The Invention of Nature: Alexander Von Humboldt’s New World.

As a retired professor of Communication Studies, I was happy to read her comments on Humboldt’s brother Wilhelm and the latter’s theory about language.

Wilhelm was an educator, interested in ideas and the pursuit of knowledge.

He identified the purpose for language as much more than simply a vehicle for the writer or speaker to formulate an idea.

Language, he said, shapes the way we look at the world.

Wulf writes, “According to Wilhelm’s radical new theory, different languages reflected different views of the world. Language was not just a tool to express thoughts but it shaped thoughts…It was not a mechanical construct of individual elements but an organism, a web that wove together action, thought and speaking.”

The way we talk about plants is the way we relate to them.

For example, as soon as you hear the word ‘succulent’ you probably have a general idea of the kind of plant it is and perhaps its growing habit as well as water and light needs.

I heard recently from a young gardener that succulents are in today. Just the mention of the word can make people who are into plants come up with their ideas of the best and worse ways to deal with this group of plants.

I remember seeing Sansevieria ‘Black Star’ in the landscape at the wonderful estate in Miami called Vizcaya. [below]

There were several beds and borders that included this Sansevieria.  It has a beautiful green color with cream edging. Thus it can add color and structure to the landscape.

Then I realized that I grow it as a house plant as you can see from this table in our living room. [below]

Sansevieria ‘Black Star’

The word ‘succulent’ applied to the genus ‘Sansevieria’  told me what kind of plant it was.

Thanks to the website for Stokes Tropicals you can learn more about this plant:

“Sansevieria ‘Black Star’ is an easy-to-grow, double-duty (indoors or outdoors), exotic-looking plant that thrives on neglect.  Tolerates low humidity. Tolerates low water and low feeding. Tolerates being root bound. Few if any plants are as foolproof to grow.

“Sansevieria is a succulent plant, and needs a well-drained soil. Sansevieria are great and hardy house plants in the United States. You do not have to have a green thumb to grow a Sansevieria. “

The word ‘ succulent’ can mean, as it does for me, Sansevieria.

Wilhelm’s theory about language helps gardeners to see and deal with the world of plants.

Of course, we can’t forget two plant words that stir up all sorts of ideas and subsequent action. They are  ‘native’ and ‘exotic.’

Empress Josephine’s Dahlia Gift

Empress Josephine’s dahlia gift

I first came across the name Aime Bonpland, the nineteenth century French botanist, while I was researching the history of growing and selling dahlias.

Bonpland (1773-1858) became the head gardener for Empress Josephine for ten years at her summer residence outside of Paris called Chateau Malmaison.

It is there Josephine insisted on the landscape style of the English garden of the eighteenth century. And so it was designed in that fashion [below]

Bonpland had been the travel companion in Latin America to Alexander Von Humboldt in their famous trip from 1799 to 1804. [below]

Humboldt and Bonpland in the Amazon rainforest (1850)

It is said that in the early 1800s Bonpland brought back from his trip dahlia seeds to present to Empress Josephine for her wonderful collection of plants.

Martin Kral writes in his well-researched paper “Of Dahlia Myths and Aztec Mythology: The Dahlia in History” that Bonpland and Humboldt saw dahlias growing all around them as they traveled in Latin America.

When he returned to Europe, Humboldt focused on writing his treatise on nature called Cosmos.

Andrea Wulf in her  book The Invention of Nature: Alexander Von Humboldt’s New World writes, “Humboldt’s botanical publications in Paris were delayed because Bonpland was now the head gardener to Napoleon’s wife, Josephine, at Malmaison, her country estate just outside Paris.”

Bonpland was a botanist, interested in plants, and slow to respond to Humboldt’s request he help with writing about what they had experienced on their trip.

It was Humboldt who would record their five years in Latin America, leaving a lasting legacy in his writing. He saw in the trip a new way to look at nature, a forerunner to what we now call ‘ecology’.

Humboldt and Bonpland were, however, a good pair for traveling together since they complemented one another with their individual skills.

Bonpland returned to Latin America after Josephine’s death in 1814.
