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

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.

Just when you think your battle against weeds is over for the summer, cooler nighttime temperatures and shorter days spark the beginning of a new crop of your least favorite plants. The question of many homeowners is: how did all the weeds get into my landscape?
There are many ways that weeds make it to the landscape. They can be brought in with new soil, mulch, container plants, dropped by birds, delivered on the fur of animals, carried by wind, or on the deck of a lawn mower. If that is not enough to depress you, then also realize that regardless of outside sources of weeds, your landscape already has plenty onsite that you don’t even know about.
In the soil, there is a large number of weed seeds ready to germinate when the conditions are just right. Understanding how your common landscape practices can encourage or discourage the germination of these seeds, can help you begin to manage some weed infestations.
Many of the seeds of common annual weeds are very small. They require exposure to sunlight in addition to the proper temperatures and moisture to germinate. Sunlight is critical, though, and seeds will not germinate without adequate sunlight. If the small seeds are deep in the soil, you will probably never know they are there. When you turn soil or disturb soil such as when installing plants, you bring the small seeds close to the surface and closer to light. They can then be stimulated to germinate. The next thing you know, you have an area covered in weed seedlings.
As mulch thins, small seeds of weeds are stimulated by sunlight to begin growing.
What does this mean for your gardening practices? Try your best to block sunlight from hitting exposed soil. You can do this by keeping a healthy turf, free of thinning spaces. A 2 to 3 inch layer of mulch in plant beds and vegetable gardens will reduce weed seed germination. Finally, when you are installing plants in an established bed, try not to mix soil with surrounding mulch. Seeds will easily germinate within the mulch if it becomes mixed with soil.
It is inevitable that your landscape will have some weeds but a few easy gardening practices can reduce some of your weed frustrations.

Building a floating hydroponic garden as a fall project could be rewarding and delicious. In the fall, lettuce, cabbage and greens are ideal for floating hydroponic gardens.

Growing roses in the South can have challenges and many gardeners think that they are just too high maintenance to plant. Plant developers are aware of this opinion and have worked to develop low maintenance roses that can make a novice gardener look like a pro.
The trend in horticulture is to develop and release plant series where closely related plants have similar characteristics but offer some diversity such as different flower color and size. A new series that is performing well in North Florida is Drift® Groundcover Roses. Available with flower colors ranging from white, yellow, pink, apricot, to red. All exhibit a low growing habit and will remain under three feet tall and spread up to four feet wide. Flowers are born in dense clusters for most of the year, only taking a break in the winter months.
Although not completely disease free, these roses do show resistance to rust, powdery mildew, and black spot which are common problems with roses. Deadheading is not necessary, but can be done to increase bloom and keep plants looking tidy. One of the best characteristics of the Drift® Groundcover Rose series is that they don’t get very tall, so they fit in small spaces. If you are looking for incredible color in a sunny site with limited space give this series a try.
Although low maintenance, roses do still require some attention, for more information read Growing Roses in Florida.
