Rayless Sunflower

Rayless Sunflower

Fall is a wonderful season for viewing wildflowers and there are many flower colors brightening our landscapes and roadsides. Amongst all the color there is one wildflower, the Rayless sunflower (Helianthus radula) that may not be nearly as showy but is very interesting in the landscape.

Many people will discover the Rayless sunflower in a moist area near the ditch or a drainage area. It has a basal set of leaves that blend into the surrounding grass. In summer a leafless stem about will emerge that is topped by a round flower with discs but no rays. It mostly appears brown but may offer a tinge of red or purple from the disc flowers.

Not everyone will appreciate the beauty of the rayless sunflower. It will be visited by pollinators and offers an attractive contrast to the greens of surrounding plant material. It is a plant suited to its preferred habitat and an understated treasure among native wildflowers.

Fall Color with Muhly Grass

Fall Color with Muhly Grass

As September rolls into October and we finally experience cooler temperatures, I always look forward to seeing one of my favorite native grasses in full bloom. Muhlenbergia capillaris, or Muhly grass, is an extremely versatile plant in the home landscape. It is both flood and drought tolerant and easy to maintain. A true local, it is typically found growing in beach dune areas, sandhills, pine flatwoods or coastal uplands. It provides nesting material and shelter for birds and small animals, and is known to attract beneficial ladybugs.

Muhly grass grows in a clumping form, usually 2-3 feet in height and width, and looks great in clusters as a border along the edge of a building or lawn. It can also be used as an eye-catching centerpiece in a landscape. The plant’s most notable feature, however, appears in late September and early October. This is when hundreds of filamentous blossoms form a dramatic display of deep pinkish purple. When the wind blows the colorful blooms, it creates an appearance of a pink cloud hovering over the grass.

Muhly grass is semi-evergreen, turning more copper in color as it gets colder. The only maintenance needed is voluntary; in late winter it can be trimmed down to 6-8″ to remove older, dead blades before the growing season. This plant was chosen as the 2012 Plant of the Year by the Garden Club of America, and is a great selection for our area.

For more information on the plant, please visit UF IFAS “Gardening Solutions” or speak to your local UF IFAS Extension horticulture agent.

 

Native Grass for Moist Soils

Native Grass for Moist Soils

Native plants can more readily be found in local nurseries to enhance landscape plantings. Not all natives are suited to every habit so it is still important to match the plant’s requirements with a suitable area in the landscape.

Gamma grass

One low maintenance native that is more suited to a specific area is the landscape is the Gamma or Fakahatchee grass (Tripsacum dactyloides and T. floridana). This clumping perennial grass grows best in moist or even boggy soils. It has attractive green foliage and upright flower stems that appear in mid summer. Although the flowers are not very significant, they do have a red color when viewed up close.

The Eastern gamma grass can grow five feet in height so many gardeners prefer the dwarf version that reaches about 2-3 feet in height. Plant in areas of full sun or partial shade as a specimen plant or use in a mass of three or five.

In areas that receive colder temperatures, gamma grass can add fall interest to the garden. Leaves will change to a shade of red with first frost and plants can die back to the ground during freezing winters. New growth returns in the spring. Basic maintenance includes pruning back in the spring.

Here’s a beautiful native perennial wildflower that is easy to grow and generally available in the independent nursery trade. In the wild, you can encounter them at the edges of woodlands and ponds as they prefer moist areas. Blue mistflower, Conoclinium coelestinumperforms well as a perennial in the home landscape but does spread easily by seed and will spread in the garden. It also spreads through underground rhizomes which allow it to form large clumps. This is an advantage for the informal garden, however, the gardener who prefers a more formal look will have a bit more maintenance in controlling that spread.

The abundant flowers look like bluish-purple puffballs on the top of the stems. The color is unusual and adds a striking touch in the garden. The bloom season is mid-summer to mid-fall. Butterflies are frequent visitors, making this an excellent addition to your butterfly garden.

Blue mistflower has a full rounded form and will grow to 3 feet under optimum conditions. Leaves are opposite and have a triangular shape. Growth and blooming is best in full sun to part sun conditions.

Give it a try!

 

 

New Flowers, Incredible History

New Flowers, Incredible History

diascia basketSince 2005, multiple varieties of Diascia have added to the U.S. fall market of winter flowering plants. Its delicate flowers are far from ordinary though.  In the early part of the last century most British gardening encyclopedias listed just one diascia – Diascia barberae – derived from seed collected by Col. J. H. Bowker and sent by Mrs. Barber to Kew Gardens, England, in 1870. Annual and perennial diascias had, of course, already been discovered and classified by several botanists visiting South Africa much earlier.  The  dainty, little annual, Diascia barberae, is not a very showy flower, but one which will appeal to the true flower lover. The flowers are rosy pink with yellow-green spots in the throat. The flowers are lipped, being related to the Snapdragons, but have two spurs on the lower lips, and are sometimes called twinspur.  It was not until John Kelly was given a plant called Diascia cordata by Edrom Nurseries in 1971 that anything notable happened to diascias again. He took pollen from his Diascia cordata and applied it to one flower of Diascia barberae. Of the nine seeds he obtained, just one was worthy of attention. He named it Diascia ‘Ruby Field’ (not for the color of the flowers, but for a lady who devoted her live to the long-term care of deprived children). Despite the popularity of this new, hardy hybrid, little more happened with diascias for yet another decade.  The boom in the diascia trade began only recently. Today’s diascia offers larger flowers, larger plants with a more open growth habit and colors ranging from scarlet through salmon and coral into pink. They bloom throughout the cooler weather and may behave as a perennial in warmer sites.  But, the uniqueness of their flower structure and ecological role are as fascinating as the flower is beautiful.  diascia flowerThe common name of twinspur refers to the two downwardly pointing spurs found on the back of the flower.  The spurs contain an oil which is collected in the South Africa wild by Rediviva bees.  The female bees have unusually long, hairy forelegs that are used to collect the oil to feed her larvae.  However, the Greek origin of the Diascia name doesn’t refer to the spurs, but rather the two sacs found in the upper part of the corolla.  The flower petals help the bees to rediviva beeorient themselves to the oil glands of the spurs.  While North Florida isn’t home to the Rediviva bee, we can grow Diascia and it is a wonderful opportunity to show the unique connection insects and plants can have.  Look for other specialized flower structures and you will find other animals that fit them perfectly, even within the species found in the Panhandle.

Community Butterfly Habitat

Community Butterfly Habitat

I recently met with a group of community volunteers who are interested in providing more butterfly habitat in our public areas. Monarchs migrating to Mexico this time of year use northwest Florida as a stopover and feeding site, but if host plants are unavailable they cannot sustain a healthy population. In addition, Gulf fritillaries, buckeyes, and swallowtails are spending time in local butterfly gardens, feeding on passion vine, butterfly bush, milkweed, and more.

The volunteers and several county staff visited three publicly-managed stormwater ponds, which are an ideal setting for what some proponents term “Butterflyscaping.” The open space, water source, and diversity of plants along the edge of the ponds lend themselves well to wildlife habitat.

When considering adding vegetation to a neighborhood common area, there are several things to consider. First is maintenance. If there’s an annual contract with a landscaping company to mow or maintain an area, you’ll want to have a discussion about excluding the new planting area from mowing to establish new vegetation. You’ll also want to look at the soil and amount of sunlight to determine the best plant choices for the area.

A variety of groundcovers, flowering plants, shrubs and small trees will typically provide food for both caterpillars and adult butterflies. Once established, these new landscape additions will not only provide habitat and color, but may end up reducing maintenance costs as well.

For more information, the UF publication “Community Butterflyscaping” is an excellent resource for landscape design, plant choices, and practical steps toward getting started with a neighborhood or schoolyard project.
