Honeysuckle & Plumleaf Azalea: Blooms In Late Summer
By the end of summer, many plants have grown tired of providing blooms for our garden. Sometimes it can be a challenge to find plants that will fill in this difficult time with flowers. A diligent gardener can find quite a few plants that bloom in late summer.
You’re probably familiar with Black-eyed Susan and Butterfly Bushes, providing the garden with blossoms this time of year no matter how hot it gets, attracting butterflies by the hundreds. You’ve seen Japanese Honeysuckle on the side of the road, or perhaps you’re even plagued with its invasive qualities in your own garden.
But have you seen our native Red Trumpet Honeysuckle? Lonicera sempervirens is a non-invasive evergreen vine that blooms almost year round, attracting hummingbirds, butterflies, and many other beneficial insects. Grow it as a groundcover, let it climb an arbor or trellis, or train it to cover a fence. You’ll be rewarded with blooms from spring to fall, and I’ve even seen blooms on mine in December! It will grow in sun or shade, but flowers more profusely in full sun.
For the shade, try Lobelia cardinalis, our native red Cardinal Flower, loved by hummingbirds. This perennial prefers moist soil, but can be grown in regular garden soil with supplemental water.
If you have a woodland garden, try the beautiful Plumleaf Azalea, an American native azalea made famous by Callaway Gardens. Rhododendron prunifolium is a rare deciduous azalea with bright red blooms in late July and August. Plumleaf Azalea prefers a cool shady spot with regular water.
Perennial hibiscus continues to offer up showy blooms in several colors right up until the onset of cold weather. There are many hybrid forms of our native perennial hibiscus, but my favorite is Hibiscus coccineus, often referred to as Swamp Hibiscus or Texas Star Hibiscus. It has attractive foliage in addition to the beautiful flowers. When I look at the blooms, it's hard for me to believe that instead of coming from Hawaii, this plant is a native of the Southeast!
And for a little later on in the season, consider adding Swamp Sunflower, a good companion for perennial hibiscus, since they both share a love for sun and water. Helianthus blooms in September with large, bright yellow flowers on tall stems up to 10 feet tall! I hope you’ll try some of my suggestions in your late summer garden as you strive to make your garden more beautiful year round.
