Black-eyed Susan, Rudbeckia hirta, has been a very popular garden perennial for generations. Fewer gardeners have experience with, or even heard of its’ close relative, brown-eyed Susan, Rudbeckia triloba. So, what is the difference between them?
- Brown-eyed Susan has more numerous flowers and generally flowers for a longer period in spring, summer, and fall.
- Black-eyed Susan has bigger flowers and bigger leaves.
- Both species are perennial, but the brown-eyed Susan tends to die out sooner after a few years. The good news is that both readily spread through seed to replace older plants.

Brown-eyed Susan is native to the eastern and central United States and, although native to Florida, it has only been vouchered in the wild in 5 counties in Florida. Gardeners can find seed and plants readily online and at a few native plant nurseries. It is best to try to source wildflower seed from plants grown in the same region. Brown-eyed Susan seed from plants grown in Nebraska or Michigan may not be as well adapted to the Florida environment as locally grown seed.
If you want to add this pollinator attracting perennial to your garden, choose a spot that is sunny or partly sunny. Although it prefers moist soil, brown eyed Susan adapts to most soil types and is drought tolerant after establishment.

As a boy in a small town in Georgia we had a St. Augustinegrass lawn. My dad started the lawn before I was born. That lawn was still doing fine when I left for college at age seventeen. I don’t remember weeds in the lawn during summer months. I do fondly remember winter “weeds” in that lawn.
To see clumps of winter annuals in our yard and in neighbors’ yards was a natural part of the transition from winter to spring. They added interest to what

would have been a plain palette of green. It was expected to see henbit with its square stiff stems holding up a display of small pinkish purple flowers in late winter and early spring. A clump of henbit was a great place to hide an Easter egg, especially a pink or purple one.
Wild geranium, another common winter annual, offered another good hiding place for Easter eggs with its pink to purple flowers. Large clumps of annual chickweed would nicely hide whole eggs. Green colored eggs would blend with chickweed’s green leaves.

Crimson clover with its reddish flowers, hop clover and black medic with their bright yellow flowers were good hiding places for Easter eggs. Plus clovers add nitrogen back to our soils.
I never remember my dad using any weed killer, he rarely watered. The lawn was healthy and thick enough to be a deterrent to summer weeds. But during fall and winter as the lawn would naturally thin and go dormant, winter annual weeds would run their course.
I’ve heard that the sense of smell provides our strongest memories. I remember the first mowing of the season with the clean smell of chlorophyll in the spring air. It was refreshing. Once mowed and as the heat took its toll, by late April or mid-May, these winter annual weeds were gone. What was left was a green lawn to help cool the landscape as the weather warmed. The lawn was mowed high as St. Augustine should be, played on and typically not worried with.
Most people have winter weeds in their lawns that let us know spring is near. Perhaps we worry too much with these seasonal, temporary plants that may have wrongly been labeled as weeds. Besides, how long have we been doing battle with these weeds and they are still here. Most lawns have countless numbers of winter annual seeds awaiting the cooler temperatures and shorter days of early winter to begin yet another generation. By May they are gone.

In the Panhandle, fall is the prettiest season for wildflowers. Our roadsides and woodlands are covered with pinks, whites, yellows, blues, purples, and even a little red here and there. Pretty as it may be, the beautiful wildflower look isn’t super appropriate for most yards. It would look unkempt, a little “wild” if you will, would be hard to manage and is probably best enjoyed in natural areas. However, we can bring some of the native colors of fall into our landscapes in a much lower maintenance, refined manner with two Panhandle species that pair excellently together, Muhly Grass (Muhlenbergia capillaris) and Darrow’s Blueberry (Vaccineum darrowii).

Muhly Grass, the native grass with the pinkish/purple panicles blooming right now, has gained much popularity in recent years, earning a reputation as a near pest/disease free, drought tolerant, attractive landscape plant. Operating in lieu of more traditional low growing shrubs in landscapes, Muhly is an airy, greenish gray bunch grass growing about 3-4’ tall and wide, lending informal, coastal texture to landscapes most of the year and really shining in fall during its flowering season. Once established, it never needs extra water, prefers little fertilizer, and only needs a rejuvenation prune (or burn – the Leonard preferred method. It’s fun and mimics the role of fire in Muhly’s native ecosystems!) every couple of years to keep it looking tidy.
Unlike Muhly Grass, Darrow’s Blueberry has not caught on broadly in the landscape industry but is no less deserving. This native blueberry species only grows a couple of feet tall, produces edible fruit that wildlife enjoy, and adds an unusual blue green color to landscapes via its tiny-leaved, evergreen foliage. It prefers the same sites as Muhly and is part of the reason they pair so well together. Our mostly sandy, well drained soils work just fine, but both plants can handle soils that are occasionally wet. A bonus, Darrow’s also has tiny, bell shaped flowers in spring that attract all manner of beneficial bee species. This makes it a must in any native pollinator garden!
As good as these species are alone, I think they are better together. In my family’s yard, we created a loose screen of widely spaced (8’ apart) Muhly Grass specimens around a pool, in the spirit of giving the area a “coastal” airy feel, and interspersed Darrow’s Blueberry in between.
The pink Muhly Grass flowers pair nicely with the green blue foliage of Darrow’s Blueberry. Photo courtesy of Daniel Leonard.
The look has been outstanding, particularly in the late summer/early fall. The pinky purple flowers of Muhly Grass complement the green-blue foliage of the blueberries nicely and provide easy, lasting color without having to worry about planting finicky annuals or perennials each season.
Landscaping with natives does not have to look wild and unkempt, nor does it have to be drab and unattractive. Combining native yet showy plants like Darrow’s Blueberry and Muhly Grass makes for an unusual, refined, nearly no-maintenance feature in your landscape. Look for these and other neat native plants at native nurseries and independent garden centers around the Panhandle. If you’d like more information on native grasses, blueberries or any other horticultural topic, please contact your local UF/IFAS County Extension Office! Happy Gardening!

American Beautyberry Photo by: UF/IFAS
Each fall, nature puts on a brilliant show of color throughout the United States. As the temperatures drop, autumn encourages the “leaf peepers” to hit the road in search of the red-, yellow- and orange-colored leaves of the northern deciduous trees. In Northwest Florida the color of autumn isn’t just from trees. The reds, purples, yellow and white blooms and berries that appear on many native plants add spectacular color to the landscape. American Beautyberry, Callicarpa americana, is loaded with royal-colored fruit that will persist all winter long. Whispy pinkish-cream colored seedheads look like mist atop Purple Lovegrass, Eragrostis spectabilis and Muhlygrass, Muhlenbergia capillaris. The Monarchs and other butterfly species flock to the creamy white “fluff” that covers Saltbrush, Baccharis halimifolia. But, yellow is by far the dominant fall flower color. With all the Goldenrod, Solidago spp., Narrowleaf Sunflower, Helianthus angustifolius and Tickseed, Coreopsis spp., the roadsides are golden. When driving the roads it’s nearly impossible to not see the bright yellows in the ditches and along the wood’s edge. Golden Asters (Chrysopsis spp.), Tickseeds (Coreopsis spp.), Silkgrasses (Pityopsis spp.), Sunflowers (Helianthus spp.) and Goldenrods (Solidago spp.) are displaying their petals of gold at every turn. These wildflowers are all members of the Aster family, one of the largest plant families in the world. For most, envisioning an Aster means a flower that looks like a daisy. While many are daisy-like in structure, others lack the petals and appear more like cascading sprays.
Helianthus
So if you are one of the many “hitting the road in search of fall color”, head to open areas. For wildflowers, that means rural locations with limited homes and businesses. Forested areas and non-grazed pastures typically have showy displays, especially when a spring burn was performed earlier in the year. Peeking out from the woods edge are the small red trumpet-shaped blooms of Red Basil, Calamintha coccinea and tall purple spikes of Gayfeather, Liatris spp. Visit the Florida Wildflower Foundation website, www.flawildflowers.org/bloom.php, to see both what’s in bloom and the locations of the state’s prime viewing areas. These are all native wildflowers that can be obtained through seed companies. Many are also available as potted plants at the local nurseries. Read the name carefully though. There are cultivated varieties that may appear or perform differently than those that naturally occur in Northwest Florida.

There is a lot to be said about early morning or late afternoon walks along a woodland trail in Northwest Florida. With so much to see, hear and smell there is never enough time to take it all in. I would suggest slowing down and look for the many colorful and interesting plants these native plant communities have to offer.
I had the great fortune to meet with a group of plant explores lead by Angus Gholson, botanist and conservationist with a passion to share his knowledge in Washington County many years ago for a 5-hour hiking adventure. We hiked an exceptional longleaf pine forest with immense flora on the forest floor. It was all but impossible to see everything.
We searched for unique and common plants in the Sandhills and Clayhills in the central and northern areas of Washington County. Here are just a few of the plants we saw along our hike and some detail about them.

St. Peter’s-wort, Hypericum tetapetalum is a wonderful Hypericum of the many we have in NW Florida. With its ability to repeat bloom petite yellow flowers from March to November, we often get the chance to revisit these trails at a later date for another chance to enjoy them. Like many repeat blooming natives, there will be weeks of rest periods with no bloom. This shrub will grow to three feet tall allowing the flowers to peak out over other plants in the pine flatwoods.
Shiny Lyonia, Lyonia lucida is another exceptional shrub with many uses. This evergreen can grow in low damp areas or with irrigation in landscapes to 10 to 12 feet tall. When found in pine forest areas they range from 3 – 6 feet tall. This Lyonia produces an attractive small bell-shaped red flower spread across a stem of last years growth similar to blueberry. Flowering can occur between November and June.

Pale Meadow Beauty, Rhexia Marianna brings a soft pink bloom to the pine forest, grass prairies and edge of full sun to part-shade wetlands. With the ability to grow in diverse landscapes in Northwest Florida it can just about show up anywhere, bloom a few weeks and melt back into the natural setting. Seeding is best completed in the fall and consistent moisture is needed for bloom to occur.
All three of the plants in this article can be found at native plant nurseries. Call the nursery well ahead of time to make sure they either have it or can order it for you. Enjoy the outdoors and adventure it has to offer.

Sunflowers, Helianthus spp., are a great choice for gardeners who are looking for some cheerful color in their landscape. Here in Florida, we have the main ingredient for success, lots of sunshine!

Sunflowers are short-lived annuals. The average time between planting and bloom is roughly 65 days. You can typically plant sunflowers in Florida beginning in late winter until early fall. Only the coldest months cause problems, and for most years that’s only November – January. Sunflowers can be planted almost anywhere there is full sun. The major selling point with sunflowers is, of course, the impressive blooms (figure 1). These yellow to sometimes orange or red-petaled flowers develop a central seed disc, with most variety’s flowers having approximately an 8” diameter.
When planting, you may choose to plant in narrow rows with close seed spacing in order to cull weaker plants later. A final row and seed spacing of 2’-3’ is recommended for full height and development of most varieties. However, you may also choose to plant in a bed, using a close pattern as seen in the photo below. In any event, sunflowers are easy to propagate by seed and are very low maintenance. Occasionally, powdery mildew and spittle bugs can be a nuisance. A general garden fungicide and insecticide will help if problems occur.

Sunflowers are available in many varieties, consisting of different color blooms and plant sizes. These sizes range from dwarf (1’-3’) to tall (10’-15’) varieties. You may wish to stake taller varieties at some point, as plants will tend to lean with no wind break in place. Here’s a few garden variety common names to look for: ‘Sunbright’, ‘Sonja’, ‘Sunrich Lemon’, ‘Sunrich Orange’ and ‘Autumn beauty’. Seed companies also have mixes available in packets. For tall plants, ‘Mammoth’ or ‘Skyscraper’ varieties will do the trick.
If you are fond of the sunflower bloom and looking for a groundcover, there are a couple of native perennials that fit this category. Beach sunflower, Helianthus debilis or swamp sunflower, Helianthus angustifolius, are groundcovers/ornamentals for landscapes and thrive in dry, hot climates and in a range of soil types. They also are great pollinator attractors.
For more information on growing sunflowers, contact your local county extension office.
