Best Tall Garden Plants

tall garden

Growing tall flowers (we’re talking at least 3′ and as high as 9′) can make your yard look stunning, but they can also serve as a living privacy fence or hide an ugly view. Lofty perennials can also make a dramatic backdrop to a garden that has plants with varying heights and colors. Here’s a list of common perennials to try in your yard.

Hardy Hibiscus

Garden Plants

This towering shrub grows 7′ to 9′ tall, just as tall as an ornamental tree. Its flowers can grow up to 12″ wide and come in gorgeous shades of red, pink and white. The only thing this giant has in common with its fragile, tropical kin is its exotic-looking blooms. It can survive winters as far north as Zone 5.

Oriental Lily

Garden Plants

These hardy beauties grow 4′ to 6′ tall and burst with big, showy flowers in white, red and pink. They smell sweet and are great for cutting gardens, clip a few blooms for bouquets and flower arrangements.


These old-fashioned, soaring flowers produce spikes of blooms in color-saturated tones of blue, pink, purple and white. The biggest varieties can reach 6′ tall.

Joe Pye Weed

Butterflies love these tall perennial plants and you will too if you’re looking to go big. Joe Pye grows up to 7′ tall and 4′ wide. It bears clusters of pale pink-purple flowers that smell like vanilla.

Cutleaf Coneflower

The cutleaf is not a coneflower at all. It’s in the same family as black-eyed Susans. It can grow to a towering 9′ tall and is covered with yellow, daisy-like flowers with coneflower-like drooping petals and domed center disks.


A staple of cottage gardens, hollyhock will bring old-fashioned beauty to your perennial border. Hollyhocks produce blooms in hot pink, red, white or black on 6′ to 8′ tall spires. Technically it’s a biennial, but it self-sows and multiplies, so you shouldn’t need to replant.


Cannas look tropical, but they’re winter hardy to Zone 7. These perennial flowers can reach as high as 6′ with big, paddle-shaped leaves and blooms in red, orange, yellow, cream and multi-color.

Maximillian Sunflower

These look like their annual cousins, but they bloom in late summer and keep making flowers in the fall. Maximillian sunflowers grow 4′ to 7′ tall and produce branches full of sunny yellow flowers.

Red Hot Poker

This exotic looking plant grows 3′ to 4′ tall and works well in groupings or in the back of a perennial bed. Spikes of red, yellow, white or orange tube-shaped flowers grow from grassy, gray-green foliage.


The tall spires of foxgloves are a vision. They grow as tall as 8′ and produce tube-shaped flowers in blue, pink or white with deep purple spots on their throats. Technically they’re biennials, meaning they’ll live two years and die. But they’re enthusiastic re-seeders and will act like tall perennial plants, coming back for years.

These are some of the best tall garden plants you can choose.
