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."

USDA Plants - spread of Purilla frutescens
http://plants.usda.gov/core/profile?symbol=pefr4
               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]

Chinese basil or perilla mint - Perilla frutescens

               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.

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-minutebuffelgrass, 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.

               For each community there comes a time when the invasive impact of a charismatic mega species finally causes an epiphany and an interest in one century of concern takes hold. Most of us are comfortably landscape illiterate and cannot be bothered with an invasive species especially if it is a plant, because most of us identify a plant as a tree or shrub, flower or grass and, then, quickly move on to our morning coffee.  We no longer know the common names, and sure enough cannot deal with the impossible to pronounce alien-exotic sounding names such as Phyllostachysaureoculcata McClure (1945) at any time of the day.

               Mount Rainier, a small town in Prince George's County, Maryland, my county, has found itself under attack from past landscape practices of its own doing, and now wants action and proposes a ban on all invasive plants. The immediacy of the idea obscures the question as to what exactly is an invasive plants, but oppressed homeowners and beleaguered politicians seldom let actual context interfere with well-meaning intentions. The press, of course, does not have the time or resources to actually talk to people who know a little or much about invasive species, but rather focus on factoids that sell news by fanning the flames of simplistic thinking.

               Invasive species issues are seldom, if ever, linear. They are not solved by direct line thinking. Simple solutions like a city ban will not solve the existing problem. This is the wicked inconvenience of invasives. Simple solution will inevitably cause unintended consequences and more problems. Invasive species impacts are wicked problems because they involve many vested interests, ill-defined definitions, limited resources  and short, near term frame of mind goals (interest is lost easily). For example, a land manager invests the money and time to remove a weed from a play ground but does not have a long term plan for what comes next, resulting in a new species quietly establishing because there was no EDRR plan put in place as part of the original plant removal. 

               Mount Rainier has a bamboo problem. Which bamboo exactly is causing the problem? This is a trick question because almost assuredly they have no idea that there are 26 species in the genus. Most likely, they are dealing with one of two possibilities, but what reference are they using to establish that identification. More worrisome is the idea that a ban will solve the problem. A ban will solve tomorrow's neighbors' incursion but today's property owners will still be left with the financial burden of mitigating the damage to get back full use of their land. The real issue is how to make existing property owners whole. Who is responsible for the loss of the use of my land when a neighbor's invasive species jumps the fence?

               There is little doubt that some species of invasives especially certain bamboos can rip part patios, chew through foundations, uproot asphalt, grow through concrete, and otherwise make practicable use of a property impossible for any reason. And these few specific bamboos are not alone in the invasive category  - just ask the Confederacy about kudzu, fire ants and pythons to name a few. It is good to remember that in spite of these facts, bamboo, as of now, mostly impacts managed gardens, properties, and landscapes. Because the term of art invasive species comes out of ecological and natural land management investigations, the labeling of bamboo as 'invasive' causes definitional problems.[1] It would be better, perhaps,  if historically we had not separated the idea of weeds and invasive plants, but we have. The so-called 'running' bamboos are destructive, aggressively harmful,'noxious' landscape weeds that do not fit well into classic invasive species categories especially those that require harm to natural areas and that require seeding pressure (something these bamboos do not do - yet). 

               For over thirty years a generation of dedicated volunteers and professionals has been trying to get the rest of us to notice that we have a problem, but until the problem costs us personally, we do nothing preferring to be ecological ostriches.

               Mount Rainier needs a plan before a law. It needs to put a cutting edge comprehensive program together that involves sustainable landscaping practices (SITES). The town needs an outreach program to its citizens on what the problem is and what they can do about it personally.  The town needs to support through information web sites best management practices for new installation and old landscape maintenance strategies (integrated pest management practices: IPM). The town should be putting together an early detection and rapid response (EDRR) program do ensure they never have this kind of problem again. And finally, Mount Rainier should be advocating for a county-wide policy, for every community is part of an ecosystem, and invasive species issues must be managed holistically at the ecosystem level.



[1] As per Executive Order 13112 an "invasive species" is defined as a species that is:

1) non-native (or alien) to the ecosystem under consideration and

2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.
