Annuals (plants that flower or produce tender foliage for one season) have just one mission and they do it well: grow fast and lush and, if a flowering variety, bloom their heads off all season long.
Most annuals thrive in summer heat and bloom nearly nonstop into fall. Remarkably versatile, easy to grow plants, they quickly fill out all those containers and window boxes whether your garden is a large backyard or a set of containers on a city balcony.But don’t just tuck them into vessels; use them in beds to fill in bare spots or provide all-season color when there’s a lull in floral flushes from perennials or shrubs.
The key to using these plants is to not hold back—they have a short growing season, especially in colder zones, so pack them in for a luxe display. Most prefer full sun, feeding with a balanced fertilizer when planted and once again during the blooming season, and regular water. Try these ten no-hassle annuals to add great color this summer. (Note some are considered a perennial in warmer zones.)
