In our gardens and yards, we teach our children that weeds are bad and flowers are good. By doing so we do them and nature a terrible disservice. There is a specific definition for flower : "that part of a plant comprising a group of reproductive organs and its envelopes". There is no such scientific clarity for a weed: "a herbaceous plant not valued for use or beauty". A flower may or may not be pretty but it has a clear function for the plant. To call something a weed is basically to say that one does not like that plant.
Most people tend to say that what grows naturally on their patch of ground are "weeds" and what they have planted themselves are "flowers". (How that encapsulates the essence of humanity's battle against nature!) We nurture what they want and kill or pull up what they do not want. Too often, what we tend to plant is something from another part of the world, something we have admired and want to have, even if our climate and soil are nothing like that plant's natural environment. Too often, the weeds we poison and pull up are food for the insects, birds, and creatures around us. Sometimes they can eat what we plant, but not often, and people do not like it when they do. Sometimes, they can move on to where native plants still exist, but we then have less of nature around us and fewer animals can survive on the reduced food source. Sometimes they are poisoned by what we import and they eat.
In the northern hemisphere, if gardeners finally succeed in getting rid of every last stinging nettle (Urtica dioica), they will also get rid of the beautiful peacock butterfly (Inochis io), whose caterpillars eat nettles.

In South America, if every clump of boring green with tiny, insignificant flowers is removed......
.........then the creature that needs it in order to survive will also be removed. Permanently.
Our habit of despising the home-grown and desiring the exotic in our gardens does ill to the environment in other ways as well. Native plants need little care, soil changes, or extra water, while exotic or foreign plants usually need extra water and fertilizers. This is when we live in a time of increasing water shortage and soil pollution and need to conserve water and keep the soil healthy.
We often read about the numerous plants in the rainforest that are being destroyed before they can have been fully identified and their properties discovered. Thus, despising what is local and native in favour of what is exotic, foreign, and maybe profitable, has meant that plants of potential medical value have been lost. The little blue flower (Stachytarpheta elatior) shown above is a perfect example. It is native to Brazil. Farmers consider it a serious nuisance because it grows easily and very densely and they kill it whenever they can. It is a food source for the Mourning Rose butterfly (Papilio anchisiades) shown above. It is also considered to be of medicinal value; its leaves are used to make a tea to treat hepatitis.
We teach children to cherish or at least appreciate nature while at the same time we destroy it. What is more, by destroying what is native, that which is their own environment, we devalue their world to them and teach them that only the exotic and cultivated is valuable. How can we then ask them to preserve nature? How to clarify this and give them a clearer message and understanding?
Start a Native/Non-Native or South/North Garden
Gardening and discovering how plants grow is all ready a part of the Early Years curriculum, but the activity can be greatly enhanced by using it to teach about the importance of native species.
Preparation - You will be creating a garden that will have two distinct halves. Plan to plant some seeds of local native plants. Then, look for seeds or seedlings of exotic plants from the hemisphere opposite to yours. To find seeds and seedlings, try mail-order seed companies as well as garden shops and markets. CAUTION - be sure to select only those plants of which no part is poisonous or an allergen. (See "101 Kid-Friendly Plants : Fun Plants and Family Garden Projects" in the list of gardening books in the panel to the right.)
Location - Are you fortunate enough to have space outdoors for a real garden? Wonderful! One way to make it much easier and more enjoyable for small children is to garden is to do so on raised beds of hay. With hay, it is possible to put earth on top and plant into that. The hay serves as a mulch to protect the seedlings from other plants swamping them. As it decomposes, it enriches the soil organically. No digging or tilling is required and raised beds are just the right height for little gardeners. Best of all, when the hay is delivered, it is great fun to jump on it and stamp it into place. WARNING - Some children may be allergic to hay and may have to miss out on the jumping part.
If you do not have a plot for your class, two window boxes will do. Even two pots will do. Label one native and the other non-native. For the natives to thrive, they should be as close to the real environment as possible, so do not put them in a dark corner or on top of the heater or air conditioner!
Gardening - Plant your seeds. Care for them. Learn about your plants. Get someone from one of the local garden clubs who specializes in native species of plants to come and give a talk to the class. Observe your plants. What insects or birds or other animals use them for food or housing? How much care do the native plants need? How much care do the non-natives need? How much water do they need? Which ones thrive? Do the local insects like any of the non-natives? They may well do. (Remember, one of Europe's most popular shrubs, the "butterfly bush", or buddleia, is native to Asia.)
Discuss - If a plant becomes covered with mites or a fungus, find out more about it. The fungus lives off of the plant and leads to its death and decomposition. Is that its function in nature? Is there a parasite of the fungus? Or of the mites? Try to help the children see that nature is interconnectedness. Like that old song about the bones ("the knee bone's connected to the thigh bone, the thigh bone's connected to the hip bone," and so on) the earth, the water, the sun, the plant, the things that feed off the plant and are in turn food for others, all are interconnected.
By learning that interconnectedness, they will begin to learn to appreciate each part of nature in its own place. With that appreciation, they will be better equipped to live within and preserve nature.
