1 For such a small place, Rhode Island packs a great deal into its borders! Tangles of rhododendron and hemlock, rocky shoreline with crashing waves, dark pine forests, glowing salt marshes, oak and beech forests, soggy bogs and swamps, shrubby thickets, golden dunes it is a wonderful state to experience the outdoors. And not only does Rhode Island have a rich ecosystem variety, but there is a strong conservation ethic in the state: Rhode Island citizens have an enduring sense of place and a desire to protect the state s natural beauty and diversity, which are also vital to the state s economy, especially tourism and the fishing industry. TYPICAL RI WILD PLANTS Within Rhode Island s diverse natural systems are nearly 2000 kinds of wild vascular plants, including: Ferns and fern allies such as horsetails and clubmosses; approximately 74 different kinds Gymnosperms naked seeds plants, such as larches, cedars and pines (21 species) Angiosperms covered seeds or flowering plants, including grasses, roses, daisies and oak trees the remaining 1900 or so) There are also a rich variety of non-vascular plants such as the mosses and liverworts, plantlike organisms including seaweeds and other algae, and the fungi, fascinating groups that are beyond the scope of this chapter. flora, from skunk cabbage to little bluestem, pink lady s slipper to red maple. The best way to become familiar with this flora is to get outside and enjoy it in its natural setting. There is always more to see and learn about, in every location and every season. Here s something you should know. Think you are immune to poison ivy? Guess again! Although you may not be affected by it for many years of your life, that can change at any time. Always treat poison ivy (and its wetland relative, poison sumac) with respect: every part of the plant the leaves, roots, stems, flowers and fruits (everything but the pollen) carries the oil that causes the itchy rash. The oil can cling to ash particles and be inhaled into lungs; poison ivy should never be burned to control it. Learn to identify these plants in every season and how to avoid them. About 75 percent of the wild plants in Rhode Island are native to the state, that is, they evolved in the region. The remaining 25 percent arrived in a variety of ways, most of them either deliberate or accidental introductions due to human activities. Many of these naturalized plants are familiar, such as common dandelion, ribgrass, English oak, Asiatic dayflower, and Queen Anne s lace. A few naturalized species, such as Oriental bittersweet or multiflora rose, become serious pests in natural areas (more information on these species is given below in the section on invasive species). At the opposite end of the spectrum from the all-too-ubiquitous invasives are the state s rarest wild plants. Approximately 325 species are listed by Rhode Island Department of Environmental Management s (RIDEM) Natural Heritage Preservation Program, which tracks rare species and critical habitats. None of these plants are found in more than ten sites in the state, and some are protected by federal or state laws. Natural Heritage-listed plants include yellow lady s slipper, fringed gentian, oak fern and purple needlegrass. Between the rarest and the peskiest is the rest of the state s GARDENING WITH WILD PLANTS Gardening is a very personal activity. Everyone has favorite blossoms, colors and forms; each garden is unique. Wild gardening is no different: there are many plants to choose from, many different parts of our yards to put them in, and many ways to combine them to create pleasing gardens. Some people who do wild plant gardening are purists, using only plants that are native to their area. Others like to mix and match both natives and non-natives. Some specialize in particular habitats, such as woodland gardens or wild meadows; while others enjoy working with a specific plant group such as mosses, ferns, sedges or grasses. As with all gardening, the only limit is imagination (and perhaps budget!); the only rules are those of ethics: avoiding invasive species and obtaining plants from responsible sources. Probably the biggest difference between ordinary gardening and the creation of wild gardens is that the wild garden seeks to work with nature, to make the landscape and the plants look as if they belong together, in the region where they 218

2 have evolved. Those who love wild gardening are challenged by the subtlely of natural design and the beauty inherent in working with the landscape. On a very practical level, many gardeners also appreciate that native plants are adapted for our local climate and soils; native plants generally need fewer soil amendments and less fuss than do plants from other parts of the world. Many wild plant gardeners also understand that their wild gardens are havens for local biodiversity: plant a wild garden and you will also be supporting other native organisms that rely on those plants. Our native plants and animals have evolved together over the millennia: animals rely on plants for food, shelter and breeding areas; plants rely on animals for pollination and seed dispersal. No organism, including people, lives outside these ecological relationships. The protection of biological diversity does not occur only in faraway rainforests, but also right here in our own yards by landscaping and gardening with native plants, you are a part of local biodiversity preservation. If you are overwhelmed by the many different choices of wild plants and types of gardens, here are some tips for getting started: Visit wild plant gardens, such as New England Wild Flower Society s (NEWFS) Garden in the Woods in Framingham, MA. Tour private gardens that use native plants; Rhode Island Wild Plant Society (RIWPS) often offers such tours. Take field trips to see wild plants and habitats in their natural settings, with groups such as RIWPS, NEWFS and the Audubon Society of Rhode Island (ASRI). NOTE: Give up dreams of that Meadow in a Can : although there are a few meadow mixes available with seed appropriate to the Northeast, most mixes contain seeds of western plants that aren t suitable for our soil and climate (and won t persist); and many include invasive species. Wild meadows can be created, but like all gardening, they require proper site preparation and plant selection. Consult with local groups such as RIWPS and NEWFS for specific information. PROCURING WILD PLANTS The primary concern in obtaining wild plants is discouraging wild collecting, which has driven some plants to near extinction. Wild orchids, lilies (including trilliums), ginseng and other medicinal wild plants, cacti and succulents are especially vulnerable to unscrupulous collecting and sales. Fortunately, there are numerous reputable sources of native plants. Local groups such as RIWPS and NEWFS are excellent sources of wild plants that have been grown responsibly and are not wild-collected. The NEWFS also offers wild plant seeds once a year. Local nurseries carry many native plants; information is available from RIWPS. There are local landscape architects who specialize in designing native plant gardens; ask RIWPS to provide recommendations. Try to purchase plants and seeds from local sources. There is increasing interest in preserving local genetic material, to protect the full range of biological diversity. Do not encourage dealers who collect plants from the wild or purchase them from wild collectors. Especially avoid purchasing wild plants over the Internet or through catalogue sales unless you are sure the source is reputable. Generally speaking, if a wild plant is cheap, it is probably stolen from the wild; please do not support these unethical activities. NEVER, EVER collect plants in the wild. In Rhode Island it is illegal to dig or pick anything that is not on your own property or on property where you have written permission from the landowner. Common sense is a good guide here: would you want someone to come onto your land and dig something up? All conservation properties (such as wildlife refuges and nature preserves) are protected. Some plants are specifically protected by state law, such as those listed in the Christmas Greens Law and those that are federally or state listed as Endangered or Threatened. Rhode Island s Christmas Greens Law protects many plants that are used for holiday decorations. Unless you have written permission of the landowner, it is illegal to pick or dig: great rhododendron, mountain laurel, sea lavender, flowering dogwood, American holly, winterberry/black alder, inkberry, trailing arbutus, any conifer (pine, juniper, cedar, spruce, fir, or hemlock), and any of the clubmosses (such as creeping Jenny and Prince s pine). 219
