In this post, we'll explore the top 10 best annual flowers to grow in your garden.

What are annual flowers?

Annual flowers are plants that complete their lifecycle (from seed to death) in one season or year. They typically bloom continuously throughout the growing season, providing bursts of color to your garden.

Why should you grow annual flowers in your garden?

There are many reasons why you should consider adding annual flowers to your garden. For starters, they are incredibly versatile and come in a wide variety of colors and sizes, making it easier to achieve your desired look. Additionally, annuals are an excellent way to fill in bare spots in your garden, and they can be used to create eye-catching focal points. Finally, because annuals only last for a single season, you can change up your garden's look from year to year by trying out new varieties.

1. Petunias

The first flower on our list is petunias. Available in a wide range of colors, petunias are a staple in many gardens because they are easy to care for and produce beautiful flowers all season long.

Why petunias are great

Petunias are an excellent choice if you're looking for a low-maintenance annual. They require minimal watering and fertilizing, making them perfect for novice gardeners. Petunias also attract pollinators like bees and butterflies, which can help boost the health of your garden.

2. Marigolds

Next up, we have marigolds. These fragrant, colorful flowers are a popular choice for borders, beds, and containers.

4. Impatiens

If you're looking for an annual that thrives in shady areas, impatiens are the way to go. These colorful flowers are perfect for planting under trees or in other areas with partial or full shade.

Why impatiens are perfect for shade gardens
