Beefsteak plant, (Perilla frutescens), a Growing Control Problem
 |
| Beefsteak plant flower http://www.biosurvey.ou.edu/okwild/beefsteak.html |
Natural
areas, parks and woods of the Lower Chesapeake Bay have yet another early detection
of a non indigenous, alien species. Perilla frutescens (L.) Britton 1894, [synonyms:
Ocimum frutescens L.; Perilla ocymoides L.] beefsteak plant,
has been found to be spreading beyond Maryland's cultivated, managed gardens
and landscapes. Escaped from gardens in New York as early as 1898, it was
reported as a weed of wastelands.[1] Bernard McMahon, the great American
horticulturalist, was selling Perilla
seed as early as 1804.[2] Marc
Imlay, the great weed warrior, has been weeding Perilla from parks in Maryland since 1998.[3]
Beefsteak
plant also known as Chinese basil; purple or perilla mint, is described on the Missori
Botanical Garden website as
"an upright, bushy annual that
is native from the Himalayas to Southeast Asia. It is related to coleus and
basil. It has become a very popular foliage annual and salad herb plant. It
grows to 1-3’ (less frequently to 4’) tall. Wrinkled, serrate, broad ovate,
medium green leaves (to 4” long) are sometimes tinged with purple. Leaves are
aromatic. Two-lipped nettle-like white flowers in spike-like inflorescences (to
4”) bloom at the stem tips in late summer and fall (August – October). Flowers
are not particularly showy. This plant has escaped gardens and naturalized
throughout many areas of the eastern and central U. S., including central and
southern Missouri. Fresh leaves are used in Oriental cooking, salads, soups and
as garnishes. Deep red leaves of some perilla varieties purportedly resemble
the color of uncooked beef, hence the common name."

Perilla
frutescens is reported as invasive in DC, IL, MD, MO, PA, TN, VA,
and WV and occurring in all states east of Colorado, parts of Canada, as well as the State of Washington on the west coast (excluding, for now, the Dakotas). The Forest Service (USDA) is aware that
beefsteak plant is often planted as showy ornamentals, that
"may readily escape
cultivation, spreading to disturbed areas where they disrupt native ecosystems.
The species has toxic characteristics and very few predators. It is ordinarily
avoided by cattle and has been implicated in cattle poisoning. Plants are most
toxic if cut and dried for hay late in the summer, during seed production. One reason
for beefsteak plants’ survival in pastures is that cattle avoid it. Sold as a
salad plant for its dark purple foliage, this member of the mint family is
extremely invasive by wind-borne seeds."[4]

Purdue Extension
Service website control recommendations include "...pulling or digging
it up, mowing it, or using herbicides. 2,4-D, Milestone®, Forefront®, Weedmaster®,
and glyphosate." Dr. Imlay, however,
notes an ominous sign that control of Perilla
frutescens, as well as control of Japanese stiltgrass, Microsteigum virineum Camus 1921[1922], is becoming much more
difficult. Imlay told me that he and his volunteers removed 100% of the
beefsteak plants by hand pulling until 2010 when many newly emergent patches in
open space and lightly shaded areas emerged. He also noted that existing patches of Perilla frutescens no longer
declined by ~80 % each year in 'weeded' sections of the park as they had in previous
years.
"In
2010," Imlay said, " I switched to herbicide treatment and sprayed 20
gallons. A great reduction occurred in 2011 and I only had to spray 2.2 gallons
along with modest hand pulling. However, in 2012 many new patches appeared, all
of which were treated or hand pulled. But this year many, many new and expanded
patches have appeared increasing the coverage of beefsteak plant from about
1/10 th acre to about 1/2 acre. As of
September 6 we have already sprayed 60 gallons and only sprayed about half of
the beefsteak plant."
While
preventing and introduction is the first line of defense, even the best
prevention efforts will not stop all harmful invasive species. In the case of
beefsteak plant, however, preventing its introduction has been off the table
for over 200 years. However using the tools of IPM (Integrated Pest Management),
such as early detection and rapid response (EDRR), at a local level can greatly
support effective management and even in some cases elimination. EDRR efforts
increase the likelihood that invasions that can lead to establishment and
spread of harmful species will be halted and eradicated. Once a species becomes
widely established in an ecosystem, the only action possible is the partial
mitigation of negative impacts. Based on the work of the ISAC/NISC EDRR
Subcommittee, NISC has approved Guidelines for Early Detection and Rapid Response.

M'Mahon's "Bad Landscape Design" Description from 1806 (and today)
In gardening,
nothing is really new. Yes, tools are invented to ease the aches and pains, and
new discoveries allow us to add just the right something to make the flower
grow or bloom a little longer, a little shorter, or a little more. Even our
ideas about design are well-rooted in the past. Design concepts that worked in
colonial America continue to enhance our
landscape enjoyment and use. The tools of the landscape design trade and the
insider-tricks that are sure to get results are well founded in the historis of
horticulture.
An amazing description, for example, of our modern suburban, cookie cutter, absent-of-any-sense-of-design
developer driven landscapes was published in 1806. Can you read this and not picture the usual 21st century McMansion subdivision
landscape or urban park installed under pressure by a developer eager to move
on with maximum profit.
"But some modern Pleasure-grounds,
in which rural design is copied to an extreme, are often very barren of variety
and entertainment as they frequently consist only of a grass lawn like a great
field; having a running plantation of trees and shrubs all round it, just broad
enough, to admit a gravel-walk winding through it, in the serpentine way, in
many short twists and turns, and bordering at every turn alternately, upon the
outward fence and the lawn; which are continually obtruded upon the sight,
exhibiting the same prospect over and over, without the least variation; so as
that after having traversed the walks all round this sort of pleasure-ground,
we find no more variety or entertainment than at our first entrance, the whole
having presented itself at the first view."[1]
If you are interested in any
aspect of gardening from fruits and berries to vegetables, annuals to
perennials, as well as houseplants, and are looking for an in-depth calendar of
work; and you want this to be completely
organic as in no use of synthetic fertilizers or pesticides, then the work for
you is The American Gardener’s Calendar by Bernard
McMahon.
M'Mahon
was born in Ireland in 1775 and came to the United States in 1796 because of
political instability in his native country. He settled in Philadelphia and
established a seed and nursery business. Very shortly thereafter he began to
collect and export seeds of American plants. Because of his work, many native
American plants became established in Europe. The History of
Horticulture web
site continues:
"In 1804 his catalogue
of seeds included 1,000 "species." He became acquainted with Thomas
Jefferson as well as other distinguished men of his time. It is said that the
famous Lewis and Clark expedition was planned in his home. His horticultural
interests were very broad and his seed store became a meeting place for
botanists and horticulturists. M'Mahon and Landreth, a noted Philadelphia
nurseryman, distributed the seeds collected in the Lewis and Clark expedition.
He published in 1806 the first really important horticultural book which was
entitled, American Gardeners Calendar. This was a standard encyclopedia for
many years. The 11th edition was published in 1857. M'Mahon was
born in Ireland but came to America in 1796 because of political instability in
that country. He settled in Philadelphia and established a seed and nursery
business. Very shortly thereafter he began to collect and export seeds of
American plants. By this means many nature plants became established in Europe.
In 1804 his catalogue of seeds included 1,000 "species".

Some bamboos run into legal barriers - legislative updates - a wicked inconvenience
The noxious, invasive in some places invasive
bamboo wars continue to grow and spread. In some sense they are 'popping up' as fast as the plant they have identified as their number one here and now enemy of the personal good.
The local weed warriors are challenged because their needs are not obvious to the disinterested rest of us, and because recent history has made an artificial division between agriculture's noxious weeds and ecology's invasive species. To the beleaguered property owner it is all the same destructive incursion and infestations that deny them the use of their property.
Local and state government are slow to act because they count voted and so far the documented infestations of problematic bamboo are dwarfed by species such as mile-a-minute, buffelgrass, tamarisk and kudzu, and because the invaded properties do not yet equal a constituency that can sway elections - mostly because it is fragmented and divided as to particular species of concern or method of control.
Who should pay to clean up the mess is the large elephant in our national political discussion from guns to energy, bamboo to atmospheric gas ratios, we have met the enemy and it is us. We do not want to pay for what we throw over our garden fences whether at the scale of an individual, a corporation or a nation-state.
We face a wicked inconvenience - plants that seem to misbehave are symptoms of our own unwillingness to take responsibility for our own actions.
