Generally, high-quality artificial flowers are quite durable. They can maintain their shape and color for a long time without wilting or decaying like real flowers. However, their durability also depends on factors such as the materials used and the environment they are placed in.

While artificial flowers have some degree of weather resistance, long-term exposure to the outdoors may cause color fading, material aging, and other problems. It is recommended to place them in indoor or sheltered outdoor areas.

For light dust, you can use a soft brush or a hairdryer on the cool setting to gently remove it. For stains, wipe them gently with a damp cloth. For stubborn stains, you can add a small amount of mild detergent to warm water, dip a soft cloth in it, wipe the stain, and then rinse with clean water and let it dry.

Common materials include polyester, plastic, silk, rayon, and cotton. High-quality artificial flowers often use more advanced materials to achieve a more realistic look and longer lifespan.

You can bend the stems slightly to mimic the natural droop of real flowers, hide the base with moss or greenery, and choose artificial flowers with detailed petals and colors that closely resemble real ones. Also, regularly dusting them can keep them looking fresh.

Considering the long-term cost, artificial plants can be more cost-effective as they don't require watering, fertilizing, or other maintenance costs like real plants. They also have a longer lifespan, making them a good investment in the long run.

Some artificial plants made of recyclable materials like certain plastics can be recycled. However, it's recommended to check with local recycling centers or the manufacturer for specific recycling instructions.
