Marigolds are often used in gardens for their ability to:

• B. Attract butterflies
• C. Grow in shade
• D. Bloom all year round

Answer: (A)

Marigolds are well-known in horticulture for their ability to repel pests, particularly nematodes and certain types of garden insects. Their roots release compounds that can deter pests from invading the soil and affecting other plants. Additionally, marigolds have a strong scent that many common garden pests find unattractive, further enhancing their role as a natural pest deterrent. This characteristic makes them a popular companion plant in vegetable and flower gardens, contributing to a healthier ecosystem by reducing the need for chemical pesticides. While marigolds can attract some beneficial insects, their primary recognized benefit is in pest management. Their growth requirements do not include thriving in shade, and they are not known for blooming all year round; they have specific seasonal blooming patterns. Thus, the ability to repel pests stands out as their most significant contribution to a garden.
