Football fans may lament that the 2018 NFL Season is in the rearview mirror, but lessons linger long after events fade. The Pittsburgh Steelers/Antonio Brown drama grabbed the headlines as he missed practices, walked away from the team multiple times, had sideline flare-ups, and went off on present and past teammates, proving once again the wisdom of Dr. Brenda Freeman: “Bad behavior left unchecked grows.”
While you probably don’t have an employee with a multimillion contract airing dirty laundry in public, you might have a rock star or specialist whose actions are inexcusable. The sooner you address bad behavior, the less likely it is to spiral out of control.
Boundaries, or clearly defined indicators of acceptable and unacceptable behaviors, protect resources and relationships. If you haven’t already, as a leader, you’ll want to adopt multiple roles related to boundaries including:
Setting and maintaining good boundaries for yourself.
Establishing and articulating boundaries for your team.
Monitoring and maintaining team boundaries.
Responding and repairing when boundaries are violated.
To lead effectively, it is imperative you have clear boundaries for yourself personally and professionally. Your management of your boundaries serves as the model for boundaries within your team. Navigating them successfully empowers you to oversee boundaries within your team.
The first step in setting good boundaries is awareness. You must know what is essential for you, and for your team, to function at the highest level. It is equally important to know you and your company’s deal-breakers. For your personal boundaries, identify what energizes you, what drains you, and what pulls you off track. Encourage your team members to make the same assessment for themselves. Then, work together to identify the same information for your team. Boundaries that your team may discuss could include a commitment to a drama-free work zone where each individual works hard, makes time for fun personally and professionally and treats each other with respect.
Find a way to communicate boundaries within your team in ways that are clear and respectful. When individuals express their boundaries, they don’t need to defend, debate, or detail their feelings. For the team, it’s important that boundaries are negotiated and agreed upon by consensus, understanding that as the leader, you may need to set specific boundaries and negotiate the middle ground between competing priorities. Examples of powerful team boundaries include talking to people, not about people, handling conflict civilly, being on time, meeting deadlines and producing quality work.
Two things to keep in mind when setting boundaries: make them few and make them important. Too many boundaries create confusion, exhaustion and opportunities for conflict. Your role as the leader is to monitor your team’s process and progress and address issues when it appears boundary violations are imminent. Recognizing potential problems ahead of time empowers you and your team to be proactive and make adjustments, rather than forcing you to respond to the damage that occurs when a boundary is broken.
Once you’ve created a boundary, view it like a fence. It separates what is acceptable from what is not. Keep in mind that fences have gates – places where people can get from one side to the other with permission. Know when it’s time to open the gate or adjust the boundary, and do it with intention, clarity and consistency. Just as landowners periodically walk the perimeter to see if fences have been breached or need to be adjusted, take time to periodically review your personal and team boundaries to see if they are working and whether new boundaries are needed.
Good boundaries make good teams, just as good fences make good neighbors. Become a boundary master and you will increase engagement, productivity and your impact as a leader.

Lavenders for the North
Features - Plant Evaluations
Despite their generally tender aspect and the constraints of their cultural requirements, some lavenders grow successfully in northern regions.
Lavenders have long been cultivated for their broad herbal and medicinal uses and are enduringly popular as ornamentals in gardens and landscapes around the world. Famously, bountiful fields of lavender grown for its fragrant oil are the essence of France’s Provence region. Lavender derives from lavare, Latin for “to bathe or wash”, because the ancient Romans steeped bundles of this aromatic herb in bathing water. Lavender is familiar in everyday life, giving its distinctive scent and color to a myriad of personal, home, and culinary goods.
Lavenders (Lavandula spp.) are Old World plants, with 28 species native to the Mediterranean region, northern Africa, western Asia, and the Middle East. While technically a subshrub, the woody stems are often injured or killed in cold winters—L. angustifolia, L. × intermedia and L. × chaytoriae are typically listed hardy in USDA Zones 6-9. Consequently, lavenders are treated as perennials in areas where stem dieback is the rule rather than the exception. The mild climate of their native range is so unlike the temperate Upper Midwest that growing lavenders may seem impossible. Despite their generally tender aspect and the constraints of their cultural requirements, some lavenders grow successfully in northern regions.
While its name would imply otherwise, English or common lavender, Lavandula angustifolia, is a native of the Mediterranean region and represented in cultivation by a plethora of cultivars. Flower colors range from shades of lavender or violet to purple, pink, and white, usually with darker or contrasting calyces. All parts of the plant are tomentose and aromatic due to volatile oils in the inflorescences, stems, and leaves. The oppositely paired leaves are generally narrowly lance-shaped, about two inches long, silvery to gray-green, and evergreen in mild winters. English lavender has a mounded habit, 12 to 36 inches tall depending on the cultivar, and can grow quite wide with age under ideal conditions.
Lavandin, Lavandula × intermedia, is a natural hybrid of L. angustifolia and L. latifolia, another Mediterranean native. There are only slight differences related to flower size and bloom season between the two species and lavandin cultivars are plentiful, too. Lavandula × chaytoriae, a manmade cross between English lavender and woolly lavender, L. lanata, originated in England in the 1980s. It has the fuzzy silver leaves of woolly lavender and some of the cold hardiness of L. angustifolia.
The evaluation study
In June 2010, the Chicago Botanic Garden (USDA Hardiness Zone 5b, AHS Plant Heat-Zone 5) initiated a seven-year lavender trial, which included 40 commercially available selections of Lavandula angustifolia, L. × intermedia and L. × chaytoriae. The impetus for the trial was a common conception that lavenders were not reliably cold hardy in USDA Zone 5; the goal was to determine the potential for growing lavenders in northern regions. Beyond chronicling their ornamental attributes, assessments were made on winter hardiness, adaptability to average growing conditions, and longevity in the landscape.
Three plants of each taxon were grown in side-by-side plots for easy comparison of ornamental traits and landscape performance. The evaluation garden was openly exposed to wind in all directions and received at least ten hours of full sun daily during the growing season, which averaged 180 days per year for the 2010-2016 trial period. The clay-loam soil had a pH of 7.4 throughout this period, and although typically well-drained, the soil retained excess moisture for short periods in summer and winter. Trial beds were raised eight inches above the surrounding turf to improve soil drainage.
Maintenance practices were kept to a minimum, thereby allowing the plants to thrive or fail under natural conditions. Trial beds were irrigated via overhead sprinklers as needed, mulched with composted leaves once each summer, and regularly weeded. Moreover, plants were not deadheaded, fertilized, winter mulched, or chemically treated for insect or disease problems. Dead stems were removed each spring after winter injury assessments were completed.
All lavenders were evaluated for cold hardiness; cultural adaptability to the soil and environmental conditions of the trial site; disease and pest problems; and ornamental qualities associated with flowers, foliage, and plant habits. Final performance ratings are based on winter hardiness, flower production, foliage and habit quality, and plant health and vigor.
Top-rated lavenders
Seven taxa received the highest ratings for exceptional flower production, healthy foliage, vigorous habits, adaptability to the growing conditions, and superior winter hardiness. Based on cumulative evaluation scores, the top-rated lavenders in descending order were ‘Imperial Gem’, ‘Royal Velvet’, ‘Munstead’, ‘SuperBlue’, ‘Jean Davis’, ‘Niko’/Phenomenal and ‘Sharon Roberts’. Phenomenal was the only top-performing non-angustifolia type.
Summary
There were two noteworthy consequences of undertaking and completing the lavender trial. Most importantly, the outcome, whether positive or negative, is informative to gardeners beyond simply anecdotal. Additionally, discovering a variety of adaptable lavenders diversifies the offerings for northern gardens. Of the 40 lavenders trialed between 2010 and 2016, thirteen selections—representing a good variety of flower colors and plant sizes—received high ratings for their overall performances. Besides robust habits and superior floral displays, these lavenders proved winter hardy and adaptable to the challenging growing conditions of the trial site. The thirteen top-rated lavenders included ‘Imperial Gem’, ‘Royal Velvet’, ‘Munstead’, ‘SuperBlue’, ‘Jean Davis’, ‘Niko’/Phenomenal, ‘Sharon Roberts’, ‘Violet Intrigue’, ‘Dwarf Blue’, ‘Loddon Blue’, ‘Thumbelina Leigh’, ‘Oxford Gem’ and ‘Irene Doyle’.
Cold hardiness and adaptability to wet clay soils were the primary concerns at the outset of the trial. Both criteria were challenges to successfully growing lavenders, and at times, it was uncertain whether one was more detrimental than the other was. While not proven in all cases, the lavenders that struggled to survive the growing conditions were more susceptible to injury from cold temperatures. Longevity was not conclusively determined but the top-performers survived and excelled for the duration of their time in the trial, which in many instances was five or six years.
All lavenders sustained some level of injury in one or more winters, although damage varied by lavender and by year. There was a direct correlation between the degree of winter stem loss and habit quality and flower production; that is, lavenders with the least amount of stem injury looked the best. A number of lavenders, such as ‘Hidcote Superior’, Lavance Purple, and ‘Mitcham Gray’, were strong performers early in their trial, but were not able to recover fully after suffering significant winter injuries.
The flower shows provided by the lavenders were quite good overall. The majority of lavenders produced copious flowers, and were ornamental for a protracted period because of the long-lasting color of the calyces. Longer floral stalks created a more dramatic flower show, which was especially notable on lavandin selections such as ‘Gros Bleu’, ‘Niko’/Phenomenal, and ‘Provence’. Plants were not deadheaded in the trial, but it was clear that removing ageing flower stems would improve the ornamental display. Winter-dead stems were removed after new growth began in spring to improve habit quality.
Through formal comparative evaluation, we realized our goal of identifying a variety of lavenders adaptable to colder regions and average to challenging growing conditions. In the end, a third of the lavenders garnered at least four out of five stars; these successes will provide greater certainty when selecting a lavender for northern gardens.

While V. trifolia ‘Purpurea’ is only hardy to Zone 9, Flip Side™ has been hardy in Athens, Georgia for a number of years, surviving a Zone 7 winter. Flip Side™ is much more compact than either parent. This is a very cool plant for warmer regions.

Undisputedly an improved selection, Summertime Blues offers multi-season interest for gardens from California to Chicago and even in the deep south. Extreme drought tolerance, a more manageable size, and sterile flowers make the perfect combination for this work horse, easy-to-care-for shrub.
