Weed or flower? Who decides?

Q: What are the biological or important differences between weeds and flowering plants in addition to the judgment of the gardener?

A: I will define weeds in places where plants grow in places that are not needed in the garden. The way of thinking about the "weeds" in the garden differs depending on the gardener. For example, do purple on the lawn have weeds and interesting spring colors?

There are biological differences between weed plants and invading plants. Weed plants are easy to spread, especially in disturbed areas, but generally do not pose a threat to conservation of autologous plant communities. Invasive plants are usually non-native plants that build themselves within existing native plant communities and pose a threat to the integrity of the plant community.

When plants are deliberately or unintentionally introduced into new places, they breed, compete with natural species and resources, and eventually even dominate the landscape. Phellodonta is an example of an invading plant in the Chicago area

Factors common to many invasive plants include rapid growth and premature aging, production of many seeds, widespread diffusion of birds and wind seeds, rapid germination of seeds, few natural enemies, asexual fertility, etc. There is.

Use regional resources to obtain guidance on invading plants. The Chicago Botanical Garden has invasive plant policies and a list of invasive plants in our area at the garden website chicagobotanic.org/research/conservation/invasive/chicago/.

Of course, I recommend you to stay in your garden. Flowers are flowers or flowers of plants and are the breeding center of whole organisms. The garden is the center where famous flowers bloom, but please do not forget that weeds will bloom. Dandelion and tick are the two most common of these weeds. For some people, these weed flowers may not affect the overall appearance of the garden, but they can get resources from your other plants. Removing all the weeds in the lawn and the garden is the best way to keep plants healthy. Field flowers are sometimes mistaken for weeds. Since the explanation about the scarcity of wild flowers is various, investigate the natural flowers of lawn and garden and make sure that they are not threatened to extinction in the area until they are killed. Flowers that are at risk are usually listed by state

Weeds are less attractive to most of us. There is no doubt about this. Green thumbs who want to enclose houses and gardens with various cultivated flowers are even more annoying. Weeds, often called harmful plants, destroy other parts of the garden with real aesthetic value. In most cases, they limit the light to the plants you plant. Weeds can spread pathogens, which will reduce your ideal plant quality. They are said to kill life from other valuable plants, and the weeds themselves have thorns.

For novice gardener, the difference between weeds and flowers may be simply the need for plants in the garden. With this basic distinction, many plants, which are actually defined as weeds, find their place in the garden for their luxurious appearance. On the other hand, for many gardeners, it is an unpleasant chore to annoy many weeds of flowers and to remove them. However, from a more scientific point of view, weeds are not so bad. Here are the basic guidelines for identifying these plants in your home garden:
