Finding flowers that will perform in Birmingham’s brutal summer heat and humidity is an ongoing challenge. Fortunately, we’ve found many that will do well…and thrive if given the right care. In a post from last summer, I highlighted a few summer annuals, and here’s an update.
A white penta in the garden…
Have you tried pentas? They are flower dynamos and butterfly magnets. I make sure to add them to my garden each year, knowing that, come the dog days of August, they’ll be hitting their stride. All they ask for is periodic deadheading to keep blooms coming and supplemental water if we go through summer dry spells. Available in a wide range of colors – white, red, pinks and lavenders – they add a rounded, star-cluster flower form to the garden.
Tall purple gomphrena
In last year’s post I highlighted gomphrena, and it’s getting an encore mention this year because I like it so much. The tall ones are my favorite, though they’ve been hard to come by this year. I’ve finally been able to find a tall purple one, though, and will be putting it in planters and recommending it to everyone for sunny, hot spots in the garden. The tall stems with rounded globe-like flowers, like the pentas, add another interesting flower shape to any flower bed.
Fanflower…
Finally, here are two low-growing plants that can be used to spill out of containers or as a groundcover in garden beds. First, one I use all the time in containers and in the ground is scaevola, or fan flower (See the “fans”?). You’ve probably seen the blue/purple selections, but there is also a white form shown here, as well as pink, a purple and white, and a yellow.
It’s interesting fan-shaped flowers are held on stems that in containers get quite long. Because of this, it will benefit from being cut back at times through the summer. You can either cut the whole plant back when it gets leggy, or you might choose to just cut a few of the longest stems back here and there. This won’t hurt it at all, so don’t be afraid to do this!
Purslane, just beginning to bloom…
Last, but definitely not least, as far as heat tolerance and toughness, and loved by honeybees too, is purslane. This little flowering succulent has been improved upon by hybridizers over the years. These improved varieties offer vivid colors from white to many shades of oranges, pinks, and reds. The flowers will close in the late afternoon, but do they make up for it the rest of the day!
New varieties have larger blooms on heat and drought tolerant plants, making them a definite winner in my book. Try them either mixed with other succulents in a container, trailing from a hanging basket, or in the ground, perhaps along a hot sidewalk or driveway.
So, while we struggle through the summer heat and humidity of the south, it’s nice to know our gardens and containers don’t have to. It’s all in finding the right plants for your tough spots and knowing what to do to keep them looking their best!
For now she’s quite content just to be with us in the back of the greenhouse, watching us work and receiving the occasional pet or hug. She’s not sure about Ozzie, greeting him with hisses and growls; but we’re certain they”ll work it out, and we’re giving Ozzie plenty of extra attention!
Jamie put together this stunning display the other day at the front of the shop, using a beautiful mix of containers and plants. The picture doesn’t do her designs justice,,,a pony tail palm underplanted with succulents; another succulent planting in cork bark; and a gorgeous arrangement of a standing cork bark planter with brassidium, or spider, orchids.
This closeup picture of the succulent plantings shows both the diversity of this group of plants and why we enjoy working with them so much. In addition to the drought tolerant ponytail palm, there are echeverias, string of pearls, string of bananas, crassulas, and variegated trailing jade plant, all right at home in her design.
While all caladiums appreciate heat and shade, there are some that can also handle sun, including ‘Red Flash’, the one shown here. These deep red leaves will mingle with the other foliage and flowers, including a copper plant, Acalypha ‘Tahitian Gold’. It was chosen for its yellow foliage to echo the yellow blooms of the thryallis. The acalypha and a red fountain grass will grow up tall, providing a nice backdrop to this composition.
Since it is a restaurant, after all, and ornamental peppers were plentiful in the nursery, those were placed next, just in front of red Dragonwing begonias. Eventually the peppers might be enveloped by the other plants, but until then they’ll contribute their small white flowers and ornamental purple peppers to the mix,
Last, a silver trailing plant. Usually I use silver dichondra for this color because it holds up extremely well in our heat and humidity where so many other silver plants fail. This year, though, I’ve decided to try a new plant…a selection of one that I haven’t had good luck with, but this is supposed to be an improved variety, so we’ll see. It’s a licorice vine, Helichrysum ‘Silver Star’. We’ll keep an eye on this one and hope for the best. It scored high marks in the University of Georgia Athens trial gardens, so I have high hopes!
A testament to its common name of cast iron plant, the aspidistra looked amazingly good considering the bone-chilling temperatures Birmingham dipped to in January. It only needed a few leaves cut out, and no thinning was required this season…probably due to the cold. A heuchera, that had been added in the 
Torenia is an interesting plant, useful in

What does all this have to do with miniature gardens, you ask? Well, these tiny gardens have been very popular the past number of years, and the garden club organizers decided it would be a fun thing to have on some of the tables for one of their meetings. And they turned to Oak Street Garden Shop for help.
Because these take a great deal of time to make, I finally gave up on waiting for new miniature garden accessories I’d ordered since my deadline to have them completed was looming…but I still had plenty of fun things to play with. If you’ve ever made one of these 
Tiny pots of ordinary houseplants also work in these gardens. Little parlor palms, ferns, polka dot plants and baby podocarpus make good companions, and selaginella is a pretty groundcover.
The key components are some really large limbs, swiss cheese philos that were too rootbound to remain in their plastic pots, air plants, bromeliads, and lots of helping hands!
While Pinkie planted the medinilla, Jamie and I played with the positioning and wiring of the larger air plants and small bromeliad. It was coming together!
Finally, a bright Neoregelia bromeliad with a moss wrapped pot was nestled in at the botttom for a pop of color at the base. A bit of spanish moss hanging delicately from the top limbs completed our project.
A stop you in your tracks plant, this one is very new to everyone, including us. Medilla magnifica’s origin is in the mountains of the Phillipines…and this is just one of 400 species! It’s an epiphyte in its native land, growing high in trees. What a sight that must be! Evidently the late king Boudewijn of Belgium was enamored of them, as well, growing them in his royal conservatories and using them on Belgian currency.
These pieces can be used either horizontally, planting along the top, or vertically, like I’ve designed this one, positioning the plants up the planter. Since it could be unsteady if it didn’t have something to stabilize it at the base, I placed it in a pulp planter that I’d covered with a layer of sheet moss. A plastic saucer underneath will protect the floor during its time indoors, then it can be used without the saucer out in the garden or on a patio, porch or other spot that has some shade.
This planting has a variety of houseplants, including nephthytis, used for its lighter green and white foliage, rex begonias for a bit of color, tooth brake ferns and a bird’s nest fern, a new selaginella with white tips called ‘Frosty’, and a large autumn fern in the top with angel vine spilling over the edge with one last, large rex begonia.
