Another golden favorite that might pique your interest is the marigold flower. There is nothing much more satisfying and beautiful than a flower that radiates sunshine! As one of the fast blooming flowers, after about eight weeks of growing, you can expect to see some blooms.

Marigolds are also pretty low maintenance and easy to keep healthy. Soil type is not usually an issue for this flower, and the sun is their best friend.

Because of this, summer is usually a marigold’s prime time. Fall and spring are great as well, but avoid growing them in winter. These fast growing annual flowers can survive in most growing zones, so if you want to grow them during the winter, put them in containers and bring them indoors. 

An interesting fact about marigolds is that they are frequently used in Day of the Dead celebrations in various countries. They also signify beauty and success and have a tendency to give off excellent feelings of warmth and kindness.

Nasturtiums are fast and easy growing flowers that are perfect for gardeners who want to double up on their gardening tasks. Not only are nasturtiums incredibly fragrant and beautiful to look at, but they can also repel a variety of insects from the garden.

These plants are known for being resilient and while they thrive in a variety of conditions, growing quickly once the soil has warmed, they can only be planted after the danger of frost has passed. Therefore, they are considered annuals in most growing zones.

Otherwise, consider growing nasturtiums in your garden. They grow rapidly, only taking about 10-12 days for seeds to germinate and producing lovely yellow, red, and orange flowers for you to enjoy. 

#4. Cosmos

Giving your cosmos minimal water will also help them flourish. If it rains that week, then there is probably no need to water them excessively. For these flowers, it is almost better to not care enough instead of caring too much.

Cosmos flowers are herbaceous perennials that can self-seed during mild winters – in the coldest growing zones, you may have to grow these plants as annuals
