Fantastic Fennel

Fantastic Fennel

If you are looking for a low maintenance plant that has attractive foliage and flowers and attracts wildlife, consider planting fennel.  Fennel was planted in the pollinator garden at the Extension office in Bay County as a butterfly host plant for swallowtail butterflies in 2014 and has been a showstopper ever since. Fennel is a short-lived evergreen perennial that will reseed in the garden, but it is easy to remove plants if you get too many. It performs well in full sun to light shade and is quite drought tolerant once established.

The fernlike foliage has a delicate texture that contrasts with most landscape plants. Large umbels of tiny yellow flowers reach for the sky each spring and attract lots of pollinators and butterflies to the garden. Fennel is a culinary herb and leaves, flowers, and seeds can be used to season dishes with the mildly licorice flavor.

Gulf Fritillaries

Gulf Fritillaries

October is an important month for butterflies. The monarchs are making their epic migration towards Mexico, gracing us with their presence as they stop to feed on saltbush or lantana plants along the coast. But our homegrown orange-and-black butterfly is showing up everywhere right now, too. The Gulf fritillary (Agrautis vanillae) is a smaller species, but also features bright orange wings with black stripes and spots. Their caterpillars come dressed for Halloween, too—they are a deep orange color with black legs and spikes. While the caterpillar is not venomous to any potential predators, the spikes are quite intimidating and serve a protective function.

Fritillary (name from the Latin “chessboard”) eggs are bright yellow and laid primarily on varieties of passionflower vines, which the caterpillars feed voraciously upon. Passion vine is an important host plant for the zebra longwing as well, which is Florida’s state butterfly.

Gulf fritillaries are found in all 67 Florida counties, and may live throughout the southeastern United States, Mexico, and central and south America. They are found in varied habitats but prefer open, sunny spots in fields, forests, and gardens. The butterfly’s wing shape puts them into the “longwing” category, as their elongated wings spread wider than other species.

In the fall, fritillaries migrate to the warmest ends of their range. By spring, they move slightly north into North Carolina or interior Alabama.

Creative Landscape Design Brings Dramatic Change

Creative Landscape Design Brings Dramatic Change

Landscapes are an ever-changing setting that can be fun to view as the seasons come and go.  We all have differing ideas of what an exceptional landscape should be.  The point to always keep in mind is what you and your family like.  Are you considering the Florida-Friendly Landscaping elements?  You always want to keep a healthy, attractive environmental sound landscape.  This brings many interesting design concepts to the table.

The kitchen table is exactly where a landscape design needs to begin.  My dad was just the opposite, he would receive or buy plants on impulse.  Load up all these three-gallon plants, take them home and plant without consideration the long-term growth, color combinations, time of bloom and many more topics.  He just loved working in the yard and growing plants.

There are basic principles of landscape design that are used as a guide. While I may stray from them from time to time, I always return to these principles.  Just keep in mind that a landscape is an ever-changing living setting that we will always work to improve.  The visual elements are based on what you see first when you enter a setting and are usually the vibrant high impact plants that may include bright bloom color, size of plant, focal plantings, leaf size and others.  The other side of the visual is the subtle presence of low impact plants with softer colors, small leaves, lower growing plant size.  This visual group often is planted en mass with a flow of plants to create a calming effect for the visitors to your landscape.

When the form of the plant is being considered, there are several points to keep in mind.  Will it have a three-dimensional impact in the landscape setting?  Is the landscape a small backyard or a one-acre open setting?  What are the maintenance requirements of the plant(s) as they mature in size?  A large tree can dominate a small area, but it may be just what is needed for shade with low plantings around it.   In a large setting, multiple large trees may be needed to create a focal point.  I have seen some wonderful tree alleys that help in directing the flow of the landscape down drives, walks, and paths.  These forms should be considered for all plants in the landscape including, trees, shrubs, groundcovers and even hardscapes.

Up next is the texture of the plant(s).  Are you looking for large and coarse or small, “softer” leaves?  You may find finely textured plants along paths or at entry areas to steps, softening the hardscape of the steps.   Are the large leaved plants open and airy, allowing light to flow through?  Large coarse leaved plants may be found at the back of landscape beds with fine textured smaller plants in front creating a three-dimensional look or even used as a focal point to pull the gaze of the eye to a determined location.

Color in the landscape has just as much impact as the plant texture, size and form.  Color can bring a bold or a soft statement.  The color is often thought of from blooms, but leaves too change in color with the seasons, from a fresh new bright green, purple, red or other colors in the spring to deeper, more mature colors as summer comes in.  Trunks can also bring unique colors to the landscape from subtle yellows to cinnamon.

There are so many things to think about when creating a long-term vision for your landscape.  Many options come in the decisions that will need to be made.  Do your research and always contact your local Extension office for more information!
