If you are looking for a cheerful annual to grow in borders and containers, it is hard to top calendula. With bright, brilliant blooms that are repeat-flowering, these long-lasting annuals can add vibrant color to any plot from May through until October - all they need is sunshine.
The end of summer is an ideal time to harvest calendula seeds. Doing so at this time is a good way to ensure you have viable seeds to propagate more of the plants you love next year. What's more, growing plants from seed is free, fun, and a great way to fill your yard with annuals that can be relied on for zingy color.
