Climate Change Garden designed to be replicated

April 6th, 2010 by Jennifer Youngman, Program Coordinator

The UW Botanic Gardens Climate Change Garden is doing more than monitoring the effects of a changing climate on plant growth and survival. (What’s the Climate Change Garden?) It’s part of a nationwide climate change education initiative entitled Floral Report Card.

Sponsored by Chicago Botanic Garden, Floral Report Card aims to integrate existing phenology citizen science programs into elementary, middle and high school classrooms through garden replication on school grounds. The UWBG Climate Change Garden serves as the model demonstration garden for teachers, students and community members in our region who want to be involved in the Floral Report Card project. The project is currently funded through an Institute of Museum and Library Services (IMLS) planning grant that supports collaborative development for adapting Climate Change Gardens and related curricula and technology for schools, teachers and students.

Floral Report Card program implementation is in its planning stages, and recruitment of interested educators and community members is underway. In May, Master of Environmental Horticulture Candidate Allison McCarthy will host a teacher focus group with local educators who have expressed interest in being a part of the Climate Change Garden.

Educational goals of the Floral Report Card include:

  • Engaging formal education institutions and communities in citizen science, field studies, and scientific research skills;
  • Increasing visitor awareness of climate and climate change impacts;
  • Understanding the social, cultural, and economic effects of climate change;
  • Understanding how plants and people can mitigate the effects of climate change;
  • Bringing more botany into the formal education curriculum; and
  • Nurturing and empowering students and citizen scientists to be “local experts” on climate change.

Allison McCarthy and Washington Park Arboretum Education Supervisor Patrick Mulligan are presenting at the “Cool School Challenge Training Workshop with a Special Focus on Climate Change and Plants” Saturday, May 1, at the Center for Urban Horticulture. Registration is currently open for this workshop.

CUH Update April 2010

April 1st, 2010 by Soest Gardener, Riz Reyes

April 2010

It’s finally beginning to feel like spring. Yes, we have our occasional bouts of cool temperatures that threaten the tender young growth steadily coming to the fore, but in true spring fashion, plants flaunt the floral frenzy that this season is known for. A new wave of spring flowering bulbs can be admired and adored here at CUH as they fill the air with their potent perfume. A mass of daffodils and fawn lilies take center-stage in the Fragrance Garden and the Daphnes are still going at it strong as they aren’t only blooming, but also pushing new vegetative growth for more blooms next season!

Nearby NHS Hall, we have a lovely, but often overlooked relative of the kiwi fruit, Akebia quinata ‘Alba’, that is so elegant and deliciously scented, no one really notices it. It is a vigorous deciduous vine (in very mild winters it can be semi-evergreen), but it is easily manageable.

In our efforts to promote and encourage research and education, a section of CUH grounds has been designated for a test plot we’ve referred to as the “Climate Change Garden”. Spear-headed by Prof. Soo-Hyung Kim, his graduate students and CUH grounds staff have begun to install beds that will feature genetically identical species selected for their biological responsiveness to temperature. Read more about it here.

Things are picking up momentum as I type so I’m eager to get outside and get on top of our cutting back and dive into some serious weeding. If we have a break in the weather, the Soest lawn is crying out for another haircut!

Ornamental grasses have begun to push their new growth so it’s time to get most of them cut back to allow them to develop. As always, we use our hedge trimmers to shear the grasses down to make the job go more quickly. Those trimmers are then put to use on the hedges themselves as our stunning Osmanthus delavayi also gets a haircut following their wonderfully scented white blooms.

April is also the month we turn on our irrigation system. In the next couple of weeks, the irrigation crew from UW Campus will meet with our irrigation specialist, Annie Billota, to check that heads are working properly and we cover the areas we need to be watered. We then set the frequency and just tweak it during the season as needed.

It is an absolutely great time to visit CUH as there’s so much to see, smell and admire. As many gardeners begin to brainstorm for their landscapes this year, our gardens are a wealth of ideas and fascinating plants!


UWBG pilots Climate Change Garden project

March 30th, 2010 by Jennifer Youngman, Program Coordinator

UW Botanic Gardens is partnering with botanic gardens across the country in the installation of a network of Climate Change Gardens that will create a nationwide “ecological antenna” to monitor the effects of a changing climate on plant growth and survival. Each Climate Change Garden features genetically identical plant species selected for their biological responsiveness to temperature. Garden monitors will record climate data and a set of standard phenological events, from first leaf to flower to fruit set. The data will be used to help predict the impacts of climate change on plants and services they provide to people and wildlife.

On March 23, 2010, Principal Investigator Soo-Hyung Kim, Ph.D, Master of Environmental Horticulture Candidate Allison McCarthy, Washington Park Arboretum (WPA) Horticulture Staff Supervisor David Zuckerman, Center for Urban Horticulture (CUH) Gardener Annie Bilotta and WPA Education Supervisor Patrick Mulligan planted a Climate Change Garden at the CUH. It includes cloned plants of eight species, each collected from four USDA hardiness zones.

Climate Change Gardens are replicated in a range of climatic conditions, yet they maintain standard growing conditions and eliminate the confounding effects of genetic variance with the use of clones. Plants in these gardens therefore act like a network of climate sensors or “phytometers.”

Plant responses to the different climates of participating gardens will allow inferences about how the species might respond to future climate change. For example, how will zone 5 plants respond if the climate becomes more like zone 7? The species selected are long-lived  species that exhibit a variety of breeding systems and wide geographic ranges, which allow them to be planted in different climates across the country. They have flowering times that are initiated by temperature, are easy to clone, and are attractive in a garden setting. Each species will be represented by four ecotypes from each of the USDA hardiness zones 4, 5, 6, and 7. The Climate Change Garden offers a methodology for citizen scientists to explore the implications of climate change for plants.

Plant species to be monitored:

  • Aster novae-angliae, New England aster, blooms August- September
  • Baptisia australis, blue wild false indigo, blooms May-June
  • Monarda fistulosa, wild bergamot or bee balm, blooms  July-September
  • Panicum virgatum, switchgrass, blooms  July-February
  • Penstemon digitalis, beardtongue, blooms  April-June
  • Physostegia virginiana, obedient plant, blooms  June to September
  • Schizachrium scoparium, little bluestem, blooms  August-February
  • Syringa rothomagensis, Chinese lilac, blooms late May- July
