June Blooms in my Georgia Garden: Hibiscus moscheutos

Annabelle Hydrangea isn't the only Southern native shrub with voluptuous blooms. Just take a look at this native Hibiscus! Hibiscus moscheutos displays blooms up to 12 inches across. The blooms on her remind me of the huge dresses worn by Southern Belles on the movie Gone with the Wind.

Hibiscus moscheutos Lord Baltimore

Also known as Swamp Mallow, Dinner Plate Hibiscus (for obvious reasons), and Rose Mallow, Hibiscus moscheutos is native to marshes in the Southeastern United States. 

Many new varieties of this hibiscus have been developed, resulting in a wide range of bloom colors and interesting foliage.

The huge blooms begin opening in late June or early July in our Georgia garden and keep coming until cool weather arrives in the Fall. Although each bloom lasts just one day, a large plant can sport several blooms at one time. Flowers come in many different shades of pink, red, or white. They might be a solid color or have a red eye or some type of variegation in the bloom.

Like Hibiscus coccineus, this plant will grow very fast if it is happy in the spot where it grows. Give it plenty of room, because by mid-summer, it can be 5 feet tall and just as wide. Rose Mallow, like other perennial hibiscus, will die to the ground in Winter and regrow from the base in late Spring.

This fabulous Hibiscus is as easy to grow as Hibiscus coccineus, as long as you have a spot in full sun and can reach it with a hose.  In my garden, this hibiscus has proved to be quite drought tolerant, as long as I give it a drink of water when I notice the leaves drooping from thirst.

Hibiscus moscheutos has a larger hardiness range than coccineus, so it can be grown in gardens further north. According to the USDA Hardiness Zone Map, Hibiscus moscheutos can be grown in zones 5-10.

June Blooms in my Georgia Garden: Hibiscus coccineus, Swamp Mallow

It's hard for me to believe people continue to spend money on those tropical hibiscus plants every year, when they could buy the hardy hibiscus instead and enjoy the same plants year after year. Hardy Hibiscus is native to the Southeastern United States and is a perennial plant that tolerates whatever weather nature dishes out. 

One such hardy hibiscus is Hibiscus coccineus, known by many common names. Folks from Texas like to call it Texas Star Hibiscus. Like most things from Texas, Texas Star can become a huge plant quickly, if it likes its planting spot. (Actually, the USDA Plant Database doesn't show this Hibiscus naturally occurring in Texas. Any of you Texans out there know different?  We welcome your comments!) Also known as Swamp Hibiscus, this hibiscus loves most or wet soil. Swamp Mallow or just Mallow is another common name for this wonderful native plant. The common name Scarlet Hibiscus speaks for itself, since the blooms definitely are scarlet in color.

Hibiscus coccineus grows beautifully beside a creek bank or pond edge, but it will grow just as well in regular garden soil. 

New foliage begins as a bronzy reddish green which I find very attractive. Leaves are shaped somewhat like a maple leaf, but some visitors who seem to be familiar with marijuana tell me this hibiscus looks like a marijuana plant. I have never seen marijuana, so I can only take their word for it. 

The blooms which can best be described by a photograph are bright red and quite large. This is another plant in our garden that attracts pollinators by the droves. I have measured the bright flowers up to 6 inches across. And whether Texas can truly claim Texas Star Hibiscus or not, the blooms are indeed star-shaped. And once it starts blooming in June, it will continue to do so until cool weather arrives in the Fall.

Hibiscus coccineus will reach a height of 10 feet or more where water is plentiful, so remember that when you plant it. 

Mix in a large amount of compost or composted manure when you plant any hibiscus, because they all enjoy rich soil. Although native hibiscus can tolerate seasonal drought, you'll get the most lush foliage and many more flowers if you can water your plants regularly. We don't have the luxury of a creek or pond on our property, but my largest specimen gets watered by the sprinkler at the greenhouse almost daily. That's probably why it's about 3 feet taller than most plant encyclopedias describe.

Hibiscus enjoys full sun and will not bloom without it. Really, no shade at all is best.

Unfortunately, Hibiscus coccineus won't thrive in the Northern states, and is winter hardy only in USDA Zones 7 and warmer. (If you are in USDA Zones 5-8, check out Hibiscus moscheutos.)

June Blooms in my Georgia Garden: Hypericum Tricolor

Another Hypericum in our garden is Variegated St. John's Wort, Hypericum tricolor. This hypericum, is beautiful even when not in flower, but the sunny yellow blooms make it even more special.

Blooms on Variegated St. John's Wort are just as bright and sunny yellow as those on any Hypericum. Pollinators just love them. I believe yellow is the favorite color of bumblebees.

But it bears repeating that Tricolor Hypericum is beautiful in the garden even when not in flower. Leaves sport a lovely variegation of green, pink, and cream throughout the season.

Hypericum moserianum 'Tricolor' is a deciduous small shrubby perennial plant. This compact low-growing St. John's Wort stays about 12 inches high and wide and has a weeping habit, making it ideal for the front of the border or even in a container.

Dark orangey-pink buds open into bright yellow flowers that attract pollinators.

Hypericums tolerate lean soil as long as it is well-drained. Regular water is best, but St. John's Wort tolerates drought, once it is established in the garden.

Hypericum tricolor foliage will stay lush and beautiful in partial shade. Here in the South, the hot summer sun burns the foliage. My plants receive morning sun and afternoon shade.

This variegated hypericum looks lovely beneath burgundy foliage of Japanese Maple or Loropetalum.

Like most Hypericums, Tricolor can be grown in much of the United States, since it is hardy in USDA Zones 6-10.
