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.

Time to Plant Strawberries

It’s time to bed up some earth and plant strawberries! That right! Fall is the proper time to set out strawberry plants for a spring harvest. It is a common misconception that strawberries should be planted in the spring in the home garden. If planted in spring, such poor timing will result in a very reduced delicious strawberry harvest. Plant in the fall to ensure a tasty treat from your garden come spring time.

Strawberries do well on soil beds built to as tall as 10 inches and 20 inches wide. Two rows 12 inches apart can be planted on each bed. The plants should be spaced 12 inches within the row. Prepare your soil in you garden where it receives adequate sunlight, eight hours of direct sunlight is best. Two pounds to 10-5-10 can be mixed into the soil bed for every 10 foot of bed. It is even better to take a soil sample for analysis to know exactly what your garden needs to produce the best strawberry crop possible. Contact your local UF/IFAS extension office for more information on soil analysis.

Once a bed has been formed and you are ready to set plants it is important to have a plan for irrigation. The type of strawberry you plant will help you come up with the correct plan.

For freshly dug bare-root strawberry plants:

  • Water with overhead irrigation frequently during the hottest parts of the day (10am-5pm) to ensure the plants to not wither and die. This will need to be done for one to two weeks until the plants are established.

For plug or containerized transplants:

  • Very little overhead irrigation will be required as the root system is intact and functioning at the time of planting. Be sure to keep the soil moist for adequate establishment of this kind of strawberry plant.

Can Your Landscape Support Breeding Butterflies?

Can Your Landscape Support Breeding Butterflies?

Adult butterflies are pretty easy to attract to your landscape if you provide flowering plants, but getting them to lay eggs in your garden is a little trickier.

Butterflies go through complete metamorphosis which means that they have four main life stages. The first is the egg, second they hatch into caterpillars (larvae) which feed and molt many times, the third stage is the pupa or chrysalis, and finally they emerge as colorful adults. Complete metamorphosis is considered a more advanced life cycle than incomplete and one of the reasons is because most insects that go through this process do not compete for food at different life cycles. For example, the gulf fritillary butterfly larvae needs passionflower (Passiflora spp.) to feed on – no other plant type will do. The adults visit many flowering landscape plants such as zinnias, butterfly bush, pentas, etc. The adults are feeding on nectar while the caterpillars are eating foliage.

Because the larvae are very host specific, you must offer the correct plant to attract particular butterflies. Luckily, we have many options in the Florida panhandle! Just remember if you would like to attract butterfly breeding to your yard, you must sacrifice some foliage to support the caterpillars.

• Gulf Fritillary – Passionflower
• Monarch – Native milkweed
• Giant Swallowtail – citrus
• Eastern Black Swallowtail – plants in the carrot family including dill, celery, fennel, and parsley
• Tiger Swallowtail – sweet bay magnolia, tulip poplar, black cherry
• Zebra Swallowtail – pawpaw
• Luna Moth – walnut, hickory, sweetgum, persimmon, winged sumac

Florida Wildflowers: Coreopsis

In our demonstration garden we are enjoying the small but vibrant blooms of our state wildflower Coreopsis, also commonly known as tickseed. After many years of its use in the Florida highways beautification program, Coreopsis was adopted as Florida’s official state wildflower in 1991.

Florida can boast of 16 different species of Coreopsis that occur in the state with most blooming in the spring but some species blooming in the summer to later in the fall. Some of those species are rare, endangered or only found in very limited areas of the state, while others are quite common throughout the state.

Many lovely new cultivars have been introduced for our enjoyment by plant breeders through cross-breeding and selection. Some you can see in the accompanying photographs in this article.

Coreopsis is an annual or short-lived perennial that makes a great addition to your garden beds. And the bees and butterflies will enjoy them! The numerous flowers readily produce seed for naturalizing in the landscape. Plant them in a sunny spot in the landscape in evenly watered but well-drained soil. Removing the dead blooms will encourage plants to prolong their blooming; you can also save the seed for replanting in new areas of your landscape.

Armyworms Wage War Via Guerrilla Warfare

Armyworms Wage War Via Guerrilla Warfare

Armyworms come in a wide range of colors and sizes.  A few of the prominent species living in Florida are beet, southern, and fall armyworms.  And the term “living” is not an exaggeration,  because Florida is one of the lucky states where it is warm enough for armyworms to overwinter.  They are the snowbirds that never leave!

Armyworms are notorious for unanticipated invasions.  They feed on most turfgrass species and most vegetable crops, but they prefer grassy vegetable crops such as corn.  Armyworms feed in large groups and their feeding has been described as “ground moving” in lawns. They feed during cooler times of the day (morning and evening) and they roll up and rest under the vegetative canopy (in the thatch layer in turf and in the base of leaves in vegetables) during the heat of the day.

Armyworms are difficult to control because of their spontaneity.  However, in the lawn they hide in the thatch during the heat of the day.  Over watering and fertilization can increase the amount of thatch.  It is important to follow UF/IFAS guidelines for home lawn management.  A good weed control program can also help to deter armyworms, because weeds serve as an alternate food source.

Numerous chemical control options are available, but softer chemicals such as horticultural oils and insecticides containing the bacteria Bacillus thuringiensis are recommended as a first line of defense.  Insecticides should be applied in the morning or evening during feeding time.  For additional control strategies and basic information please visit the UF/IFAS Armyworm Publication Page.
