10 TALL PERENNIAL FLOWERS

Tall perennial flowers are a fantastic way to add height and structure to your flower garden. They work wonderfully at the back of borders, helping to conceal unattractive fences while also providing added privacy. Here are 10 stunning and easy-to-grow tall perennials to consider for your garden.

BLACK-EYED SUSAN (RUDBECKIA HIRTA)

Black-Eyed Susans are vibrant yellow perennials that can reach heights of up to 3 feet (90 cm). They thrive in full sun and benefit from regular deadheading to extend their blooming period. To prevent overcrowding, it’s recommended to divide them every 3 to 4 years.

Alliums

Alliums are striking tall perennials from the onion family, known for their large purple flower heads made up of numerous small blooms. These flowers can reach heights of up to 4 feet (120 cm). They thrive in full sun and typically bloom in late spring to early summer.

African Lily (Agapanthus)

Agapanthus is a clumping perennial that produces beautiful bluish-purple or white flower heads, reaching heights of up to 4 feet (120 cm). It thrives in full sun in cooler climates or partial shade in warmer regions. To maintain healthy growth, Agapanthus can be divided every two to three years, once the plants have finished flowering.

Red Hot Poker (Kniphofia uvaria)

Red Hot Poker, also known as Torch Lily or Poker Plant, is an excellent choice for attracting birds and butterflies to your garden. These striking plants can reach heights of up to 5 feet (150 cm) and spread up to 3 feet (90 cm) wide, so they require ample space to thrive. They grow best in full sun and can be divided in the fall to promote healthy growth.

Cardinal Flower (Lobelia cardinalis)

Cardinal Flowers are striking red perennials that attract hummingbirds to your garden. Although they are short-lived, typically lasting 3 to 4 years, they self-seed easily, ensuring new plants will flourish each year. These plants usually grow between 3 to 4 feet (90 to 120 cm) tall, but can reach up to 6 feet. They thrive in both part shade and full sun, and are also deer resistant, making them a great addition to your garden.

Gladiolus

Gladiolus, also known as Sword Lily or Gladdies, are vibrant perennials that grow 3 to 4 feet tall and come in a variety of bright colors, including pink, purple, red, cream, yellow, and orange. Depending on your climate, Gladiolus can be grown as annuals or perennials. In areas with freezing winters, the corms can be dug up and stored indoors until spring, while in warmer climates, they can be left in the ground over winter. These plants may require staking to protect the flower spikes from strong winds. Gladiolus also make stunning additions to flower arrangements, and the stems can be cut once the lower flowers start to bloom.

Foxglove (Digitalis purpurea)

Foxgloves are beloved perennials known for their tubular flowers that line the stems. These flowers come in a range of colors, including purple, pink, yellow, white, and red. Foxgloves thrive in full sun or part shade, but in hotter climates, they may need some afternoon shade to prevent stress. While they self-seed readily, removing dead flower spikes can help prevent unwanted plants from sprouting in your garden.
