Whether you're growing shrubs for privacy, to add height to a garden space, to cover or hide an unsightly structure, or simply for the heck of it, a flowering shrub can be an easy way to get the best of both worlds: the size of the larger plant with the additional joy of perennial flowers.
Flowering shrubs come in all shapes and sizes, from just a few feet tall, to towering, nearly tree-like. There are shrubs that grow quickly (but will need regular pruning). And there are shrubs that are very low maintenance. Here are our favorites for practically every need.
What's the easiest flowering shrub to grow?
Most shrubs are relatively easy to maintain once they're established in the ground, though some, such as certain hydrangeas, require regular pruning, and most will benefit from fertilizer during growth periods.
But just because you can doesn't mean you have to! Both shrub roses and weigela are low-maintenance shrubs that don't need a ton of pruning and often do quite fine in a range of soils without a lot of fertilizer.
What shrub flowers the longest?
All of these shrubs will produce blooms, but which will produce the most blooms, or keep blooming and blooming? Unfortunately the answer is: it depends.
There are varieties of shrubs that have been developed specifically to rebloom—such as bigleaf hydrangeas or encore azaleas—while other varieties of the same plant only bloom once. And again, how you care for the plant can have an effect. By deadheading roses (among other plants), you can get them to keep blooming for an extended period. (Here's our deadheading guide.)
Basic shrub planting and care tips
Before you buy a shrub, especially online make sure it will survive in your area's USDA Hardiness Zone. (Find your zone here.) Be aware the map has been recently updated. Read why, here.
Once you've figured out if your preferred flowering shrubs can grow well where you live, you want to consider spacing and lighting needs and where it would do best on your property.
To plant a shrub, dig a hole about two to three times as wide as the root ball, and only just about as deep—or a little less. Place the ball in the hole and back fill with the native dirt. Tamp down, gently, and water well. Water daily for the first few weeks, then weekly until the plant is fully established.
Pollinators love honeysuckle—and it's easy to smell why! The dreamy scent of the flowers—like honey and vanilla—takes us right back to grandma's garden in the summer.
Look for natives like Northern or Coralbush. Some varieties are invasive.
