Where are they a problem?

Invasive plants disrupt many natural habitats. They are most threatening in ecosystems such as wetlands, sand dunes, fire prone areas, and serpentine barrens where rare native plants are found. Invasive plant species thrive where the continuity of a natural ecosystem is breached and are abundant on disturbed sites like construction areas and road cuts. Even foot traffic can create a temporary void that is quickly invaded, some national parks have restricted the areas where visitors are allowed to walk with the warning, "we can watch purple loosestrife grow from people's footsteps."

Why are they a problem?

It's a matter of ecology. In many cases, plants from other parts of the world are welcomed, manageable additions to our gardens. However, in some situations these non-native species cause serious ecological disturbances. In the worst cases, invasive plants like mile-a-minute, purple loosestrife, and kudzu ruthlessly choke out other plant life. This puts extreme pressure on native plants and animals, and threatened species may succumb to this pressure. Ultimately, invasive plants alter habitats and reduce biodiversity.

Where do they come from?

In some cases, invasive plants arrive purely by accident, the seeds in agricultural products, or on shipments from overseas. In other cases, invasive plants are selected for their horticultural attributes. Beautiful, unusual, exceptionally hardy, drought-tolerant, or fast-growing plants are sought after by gardeners the world over. Unfortunately, plants selected for their resilience may be invasive because of their adaptable nature. Plants selected for their aesthetic value may be hard to banish from your garden even after their invasive tendencies are revealed.

What Can You Do?

Contact your local natural plant or state Department of Natural Resources to find out which plants are invasive in your area.

Learn to identify locally important invasive plants.

Start your florist
But figuring out the average selling price of an arrangement will depend on the size, style, and quantity of material it carries. A new flower stem normally lasts two to three weeks, while if it is a frozen product the period will shorten to four or 10 days.

Remove invasive plants on your property or prevent their spread.

Only use non-invasive plants when landscaping your property.

If your property borders a natural area, consider using only native plants in your landscape.

Find non-invasive or native alternatives for invasive landscape plants.

Use systemic herbicides carefully as a last resort to remove invasive plants.

Make others in your neighborhood aware of invasive plants.
