Jim Calkins, landscape and production horticulturist, Research Information Director at Minnesota Nursery and Landscape Association and former University of Minnesota instructor

'Tis the season... for seed collecting. By this time of year most plants are producing seeds, and whether you wish to harvest a bit of natural bounty or get ready for next year's garden, it's important to get the details right! Using the Arboretum's late­-summer grounds and gardens, Jim Calkins will show you what seeds are worth collecting and demonstrate proper techniques to ensure that you have healthy, vital seeds that will sprout when you plant them next spring. This is an exclusive opportunity to collect and bring home seeds from annuals, herbaceous perennials, and woody species at the Arboretum!

Peter Juhl, stone balancing artist, www.temporarysculpture.com

Get balanced! Dazzle your friends with a new skill that looks like magic, but combines elements of meditation, sculpture, and performance art. Peter will explain simple techniques using shape, weight, and friction to create impossible looking balances using ordinary stones. You'll get plenty of hands-­on time and coaching to help you develop your new­-found abilities and overcome obstacles. You'll also gain insights on photographing your creations, and learn about design, composition, and helpful tips on more advanced balancing. You'll leave grounded, refreshed, and able to repeat your balancing act in your own garden. You'll never look at stones in the same way again! This workshop is designed for adults; because a general understanding of gravity and physics is discussed, suggested minimum age for this class is 12. An assortment of practice rocks will be available to use during class. Limit 24, Tashjian Bee and Pollination Discovery Center

Saturday, February 25, 9 a.m. - 11:30 a.m.
Jim Calkins, landscape and production horticulturist, Research Information Director at Minnesota Nursery and Landscape Association and former University of Minnesota instructor

As much as we love our gardens in the summer, there is an undeniably long winter season in which we still wish to enjoy them. When you purchase plants, garden center staff always assure you that they will add "winter interest", but how do you know whether such plants will actually enhance the view from your kitchen window or just disappear under yet another snowdrift? Come take a walk with Jim, who will guide you around the Arboretum in winter and show you our very best cold weather beauties, from woody and herbaceous to flowering and fruiting. Inside, Jim will also explain what steps you can take during the growing season to help them look their best in winter. You will leave with inspiration, plant lists, and a renewed motivation to enjoy your winter garden. Dress for the weather! Limit 15, meet at the Visitor Center
