Dandelion: Friend or foe?
It seems that the lowly and much maligned, alien dandelion (Taraxacum officinale) does benefit the soil in which it grows. It prefers to root in decalcified, poor soil.
Its strong taproot then breaks into the soil and, from below the hard pan, brings up calcium and other minerals, which become available to other plants when the dandelion dies. I suppose what this means is that you should compost the dandelions you pull, after removing the seed heads.
Dandelion seed, by the way, is somewhat different from most other seeds. It contains an asexually produced embryo that is a clone of the mother plant (you might say that you’re killing the same plant over and over). Since the embryo is genetically identical to the mother plant, which survived and reproduced in a given region, the embryo stands a much greater chance of survival than might a sexually produced seed.
Members of the families Rosaceae and Asteraceae are also capable of this sort of reproduction, called apomixis, which is independent of fertilization. You can check this for yourself in Peter Raven’s sixth edition of Biology of Plants.
Wild Sprouts
Kim Lowman Vollmer, the Kids’ Committee Chair of the Rock River Valley (IL) Chapter sent us this inspiring bit of news.
“Because children are our future and all too soon they will be in charge, it is important for them to have respect for and love of nature. As Wild Ones members we can help children become responsible protectors of earth.
“Therefore, it seems important to include children in nature activities. Last fall our chapter began this process when we had our first activity for members’ kids, grandkids, and young friends. We had a wonderful time collecting seeds, learning about all the ways seeds travel, how to germinate them, and to identify new plants.
“Based on our initial success, we formed a Kids’ Program Committee. In addition to educating and inspiring our own children and grandchildren, we hope to be a resource to other educators/organizations in our community.
“With Earth Day activities in the air we had our first Children’s Activity for the year on April 28. On a cold blustery day we spent two hours hiking, investigating, learning, and enjoying nature with five enthusiastic four- and five-year olds. The children, with the help of the adults, identified 25 species, most of them in bloom. Everyone had a great time and the kids all left with smiles.
“Up-coming activities include Binoculars-to-Berries in late June, Insect Investigation in August, and Seed Collecting in October. We may even attempt a community service/ stewardship project. Our young environmentalists are called the Wild Sprouts.”
Rescue or salvage?
A friend recently asked me this question: When we dig plants from a site about to be bulldozed, are we performing a rescue or a salvage operation?
He argued that if the plants are replanted in isolated places, never to communicate with another of their own kind, which is what we do when we plant them in most urban and many suburban gardens, it is a salvage operation.
On the other hand, if the plants are moved to a protected natural area, where they grow with other members of the same species and within a natural community, the genotype of the stand is enriched and the plants’ life spans will be longer. This, he argued, is a true rescue.

Local miracle under the oaks
One of the places where the Fox Valley Area (WI) Chapter meets is Evergreen Retirement Community, a non-profit, full-spectrum housing complex for the elderly in Oshkosh.
Along one side of the site is a lovely six-acre oak-hickory savanna. As most readers know, an oak-hickory savanna is a rare, ecosystem which is threatened around the globe. Some chapter members have worked hard to remove the invading buckthorn, releasing the shooting stars, wild geranium, fringed loosestrife, Michigan lily, starry Solomon’s plume, wood violets, great blue lobelia, and other flora which are part of the natural community.
The challenge now is to manage the buckthorn and remove as much of it as possible. In order to do this the savanna has been divided into smaller parcels that an individual “steward” might adopt and manage. The idea is that many hands make light work and that a sense of ownership keeps a volunteer enthusiastic about a project.
Stewards will work independently after training and will probably spend about 40 hours volunteering during this growing season. A sign in each area will name its particular steward.
Evergreen’s management is very excited about and involved with this project. The area, which is too low to develop and borders Sawyer Creek for more than 1,000 feet, is open to the public and has paths through it.
