Winter Invasive Plant ID at Turtle Cave in Athens, Ohio - Honeysuckle, Multiflora Rose, and Privet

            For New Year's Day, 2024 I was lucky to have a partner and dog willing to put up with some winter nippiness and muddiness to hike a nearby trail that promised a cave at the end. While there, I documented several things including the abundance and distribution of invasive plants, the plants with wild bonsai ("yamadori") potential, the details of the natural deciduous deadwood decay patterns here in Ohio, and some rock formations that were interspersed in the forest. In today's article, I share the observations from there focused on Ohio invasive plant identification ahead of our upcoming CBS invasive digs. In the near future, I'll follow up with more pictures from the other observations.

With the density of these privet berries, it's easy to see how they can invade our forests! If you look closely you will also see an invasive Japanese Honeysuckle vine still hanging onto its leaves.

Plants that Signal an Early Spring in Ohio - Living Alarm Bells

            While seasons come and go the exact when of their coming and going is always an unpredictable and complex question. Predicting these events is important for people who work in natural seasonal cycles with plants and animals such as farmers, hunters, gardeners, bonsai artists, bird watchers, and other sorts of nature enthusiasts. Many people don't know this but within us all there are internal biological clock proteins - this is where circadian rhythm comes from. So this may be one way that critters and plants can tell the progression of time. However, an event like triggering a migration or waking up from hibernation is critical to get at the right time. Migrating too late or waking up from hibernation too early could mean death by cold and lack of food. Migrating too early could mean missing the window with the rest of your species to mate or not maximizing your own energy reserves before migrating. All things in nature are a matter of risk, reward, and natural selection. As these are such critical events for the survival of an individual plant or critter, they use multiple cues to detect when to get moving. One cue can be their internal clock as we discussed. Another could be the temperature. Another could be the day length. This combination of cues is how plants and animals can time their seasonal events according to seasonal variation. Thus, while humans are trying to predict how winter in February 2024 will progress using historical data, the farmer's almanac, and a groundhog's shadow, the plants around us already have a good idea of what is the likely scenario regarding our winter. Once you look around enough to know which plants are the first responders to spring, then you also can get warning signs to get your gardening and bonsai preparations into high gear. In this post, I will share some example species which are plant alarm bells, especially in Ohio, but some ornamentals or invasives we have here also are available and could act similarly across the temperate world.

Simplified Protocols for Yamadori Collection, Aftercare, and Initial Bonsai Training - A Honeysuckle Raft Case Study.

            In preparation for the 2nd Annual CBS / Columbus Recreation & Parks Department Invasive Honeysuckle Yamadori [Wild Bonsai] Dig event, I wanted to put to words a very simplified protocol for how to take a freshly dug yamadori from the forest and how to begin to train it as a bonsai tree. Obviously, the speed of development varies based on the species and health of the tree and some steps may even occur at seasonally different times especially if you are in a different climate than me here in USDA Hardiness Zone 6, Ohio, USA. Noting that these exceptions are bound to hit you at some point, let this be a starting point and take it for what it's worth. To exemplify that protocol, let's follow the development of my extra large honeysuckle raft yamadori which I rescued from culling in a local Columbus park at last year's first invasive removal collaboration. You can read about our previous experience hosting that event here, and you can see other examples of renowned honeysuckle bonsai here.

Recapping the 1st Annual Columbus Bonsai Society Invasive Yamadori Dig with the Columbus Metro Parks

Source Material: April 2022

            As spring continues to hum right into summer here in Ohio, let's continue our series on the invasive honeysuckle species common in the eastern US. As already outlined in the previous article in the series, several distinct species of invasive honeysuckle (genus Lonicera) are similar in their characteristics, similarly suitable for bonsai, and have even yielded some show-quality bonsai specimens by prominent artists. These species are the Japanese honeysuckle/Lonicera japonica, Amur honeysuckle/Lonicera maackii, Morrow's honeysuckle/Lonicera morrowii, and Tatarian honeysuckle/Lonicera tatarica (see here for more info on these species and their bonsai suitability). Furthermore, the fact that these species are invasive makes them a doubly attractive candidate for practicing collection of wild bonsai due to their abundance and the many interested landowners who are eager to be rid of them! The topic of collecting these wild prebonsai specimens brings us to today's topic - recapping the creation of a collaborative event with the Columbus Metro Parks to remove these unwanted invasive honeysuckles from city parkland and save them for members of the Columbus Bonsai Society (CBS). This event focused on invasive species removal could be a model for bonsai practitioners in areas where public land does not normally permit tree collection and for those who live in urban areas without access to private land for wild bonsai collection.

The botany professor-style hat proves function > fashion whether digging in the sun or rain! Also pictured, my new 8-foot honeysuckle raft which occupied the entire length of my SUV. This is one bonsai that will likely just live at home permanently, or perhaps in the future, I will divide it into 2 trees that are more portable.

Invasive Japanese Honeysuckle (Lonicera japonica & related species) for Bonsai

            It's May which means that trees here in Ohio have been slowly waking up and spring is creeping northward! This also means we just passed the best time of year to root prune trees for repotting or for collecting wild trees to train as bonsai. Although collecting wild bonsai is an exciting method to gather prebonsai, many bonsai artists are unable to utilize this source of bonsai material due to a lack of access to public land where tree collection is permitted or some novices with such access may just be too intimidated by the prospects of killing trees during transplanting. One solution to both of these issues is to coordinate with local governments on removing unwanted, invasive species and attempt to utilize those species for bonsai. This three-part article series will cover a story of local collaboration in Ohio doing just that. I am happy to report that the Columbus Metro Parks now have a few less invasive Japanese Honeysuckle to worry about and the members of the Columbus Bonsai Society were allowed free access to digging wild bonsai material from our local forests. Additionally, this event allowed interested CBS members to learn about digging wild trees in a guided and hands-on fashion while also practicing guilt-free on material that is limitless (invasive trees) which would otherwise be destroyed during the city government's efforts to maintain native ecosystems.

            Today's portion of this 3-part series will focus on the invasive Japanese Honeysuckle and related Lonicera species which we collected at the CBS Honeysuckle Dig event last month. Below you will find specimen bonsai showing the potential of these species and observations from the woods as to which honeysuckle trees may make good bonsai. Future installments will cover the club dig event itself including essential information on the basics of what tools are needed and how to dig from the deciduous forests of Ohio. Finally, the last article in the series will cover other invasive species of the United States (with links to resources for other locations around the world), highlighting those which have known bonsai potential.

This honeysuckle was collected by the late Nick Lenz and has been styled and cared for by Nick's student, Andy Rutledge (Source). The face carved into the tree fits nicely with Nick Lenz's signature macabre and fantastical style; you can see more examples of this style in an earlier article I wrote on the subject.
