From about mid November or December to March, deciduous trees have little to no foliage making us more aware of their shapes, forms and barks.
Here are a few trees to consider for adding winter appeal to your landscape.
Gary Knox, UF/IFAS Horticulturist, describes the crapemyrtle’s winter interest perfectly in his publication, “Crapemyrtle in Florida.” Knox writes, “When the leaves fall in winter, the crape myrtle becomes a living sculpture. The trunk and branches of tree-form plants have an attractively gnarled, sinuous character with smooth bark. Strips of bark peel off (exfoliate) in early summer to reveal mottled new bark ranging in color from pale cream to dark cinnamon to rich brown to bright orange.”
Here are some recommendations for crapemyrtles with attractive bark. ‘Acoma’ is an outstanding semi-dwarf hybrid reaching a mature height of 10 to 15 feet that has creamy beige bark and snow white flowers. ‘Apalachee’ is another outstanding selection with cinnamon orange bark and light lavender flowers. Its mature height is about 20 feet. The cultivar ‘Osage’ produces dark orange bark and medium pink flowers with a 20-foot mature height. ‘Fantasy’ is a large maturing variety growing to more than 20 feet tall with outstanding red orange bark and white flowers. More cultivars are listed in Knox’s publication available at http://edis.ifas.ufl.edu/MG266.
River birch is another tree with unusual papery peeling bark. The cultivar ‘Heritage’ is the closest to a paper white birch that will tolerate our hot summers. Expect a river birch to reach 40 to 50 feet in height and 25 to 35 feet in width.

lia, Chinese elm, provide winter interest. “The showy, exfoliating bark reveals random mottled patterns of gray, green, orange and brown, adding great textural and visual interest, especially to its winter silhouette,” writes Ed Gilman, UF/IFAS Horticulturist, in his factsheet on Chinese Elm. This and other tree factsheets are available at http://hort.ifas.ufl.edu/woody. ‘Drake’ and ‘Allee’ are two popular Chinese elm cultivars. Chinese Elm can reach 80 feet in height but is more often seen at 40 to 50 feet with an equal spread.
American Hophornbeam, Ostrya virginiana, is an underused tree that grows to about 50 feet in height. Its grayish bark peels off in longitudinal strips revealing orange patches underneath.
Acer buergeranum or trident maple is a small, underused and hard to find tree. It usually is seen with multiple stems originating fairly low on the trunk giving the small tree a bushy appearance. It has noticeable orange-brown peeling bark.

As the holiday season comes upon us, many folks will be spending their weekends scouring tree farms and mall parking lots for the perfect Christmas tree. There are many very realistic-looking options for artificial trees these days, and they are a great way for families to reduce waste by reusing the same tree year after year. However, a live Christmas tree brings greenery inside, smells wonderful, and provides a central focus for many of our holiday traditions. Many cut trees will last over a month with good watering, but when the holidays are over, what do you do with your tree?
Many cities and counties offer a Christmas tree recycling program, in which trees can be left at drop-off sites or on the curb for pickup. Most municipalities turn the trees into mulch and use it at public facilities. Many individuals reuse trees by placing them in lakes or other water bodies as fish habitats, creating reefs for hiding and nesting. However, be sure and check with local environmental agencies before placing trees under water. If you own a good bit of land or a wooded area, you can lay your old tree out for small mammals and birds to use as shelter. It will eventually biodegrade and add nutrients to the soil. Be sure that if you take advantage of any of these recycling options that you remove all ornaments, tinsel, or other decorations which could be hazardous to animals and/or wood-chipping machines.
There is an option to truly keep your tree evergreen—a live Christmas tree! Many retailers sell potted trees that can be brought inside and decorated, then planted outside after the season is over. One of the plants often associated with this festive time of year is holly, which is an excellent choice for evergreen color throughout the year. There are many native varieties, such as yaupon holly for drier areas and myrtle-leaved holly for wetlands. Hollies are typically used as shrubs in the landscape, although many species can grow into small trees if allowed; the East Palatka holly can be as tall as 45 feet at maturity! Hollies are also an excellent food choice for attracting birds, and the shrubs work wonderfully as a natural screen. While their branches aren’t quite as sturdy as some of the northern varieties, native Atlantic white or Eastern red cedar–or even some local pines–are also excellent evergreen species that can be used.
A live tree or one planted and decorated outdoors is a wonderful way to commemorate a special Christmas and help provide wildlife habitat year-round.

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 coelestinum, performs 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!

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.

This autumn you may notice shrubs with long, arching branches sporting clusters of shiny purple berries. That beautiful sight is the Beautyberry, or Callicarpa americana. This native is found throughout Florida and the southern United States, west into Texas and north to Tennessee and Virginia.

In the spring, lavender flowers adorn the branches and are a favorite of bees. The flowers eventually give way to the shiny purple berries in the fall. Birds find the berries very attractive and will feast on them when found. Mockingbirds and cardinals are especially fond of them. If you plant this shrub for the birds, one or two plants will provide more than enough of the berries to satisfy their appetites.
Beautyberry is adaptable to a wide variety of soils and moisture. After it gets established it is drought tolerant, however it can also do well in a moist area. A spot in your garden that gets partial sun is a perfect location. Plants in too much sun sometimes get a bit yellow and those in too much shade get leggy and don’t set as much fruit. Beautyberry is deciduous, meaning that it will lose all its leaves in the winter. Therefore, you may want to place it in an area of your yard where it won’t be a focal point in the winter.
This lovely plant is usually readily available at independent nurseries. If you prefer to grow your own, beautyberry is easy to propagate and grows rapidly. Snip off an approximate 6-inch piece from the end of a stem; the cut piece should have 5 sets of leaves. Snip off the bottom 2 sets of leaves – this part of the stem will be in the soil and roots will emerge from where the leaves were removed. Also snip off the top of the stem to include the top set of leaves. Your cutting will end up with only 2 sets of leaves. Immediately put the cutting in a good potting soil, making sure that the lower part of the stem where the 2 sets of leaves were removed is below the soil line. Keep the soil moist as the cutting develops a good root system.
You and the birds will enjoy this lovely shrub for years to come!

I think it’s safe to say fall is officially here. Shouts can be heard from local football stadiums, occasionally a crisp fall breeze will send us looking for a light jacket, and coffee shops are pushing all things pumpkin. Now that we can officially appreciate the cooler fall weather, it may be time to stretch our legs and marvel at the spectacular show of color our landscapes are putting on. Here are a few plants that are showing off this time of year.
Firebush (Hamelia patens) – This charming Florida native will delight everyone with beautiful orange-red flowers throughout most of the year. Hummingbirds and butterflies enjoy the nectar in the flowers. Firebush can reach a height and width of 8 to 12 feet. It is a fast growing plant that will grow well in part to full sun environments.

Salvia (Salvia spp.) – Salvias are great plants for bringing butterflies and hummingbirds to your garden and as a bonus, they have no serious pests. With hundreds of annual and perennial species coming in an array of colors and sizes, you can easily find one or more to complement your landscape. Salvias perform best in full sun environments and are considered drought tolerant.

Turk’s Cap (Malvaviscus arboreus) – Turk’s cap can add a cheerful pop of color at a time when little else is blooming. This old-fashioned Florida-Friendly shrub like perennial is related to the hibiscus. It’s known for its bright red flowers that always seem ready to open, but never do. Turk’s cap starts blooming in summer and keeps going until through winter, unless hit by a hard frost. It can grow in full sun and reach up to ten feet tall and ten feet wide, so give it room to grow. This easy-care native perennial requires little maintenance once it’s established.

Coleus (Solenostemon scutellarioides) – When imagining fall color we often don’t consider coleus. However, the vibrant foliage can add interest to any landscape throughout the fall. Coleus is prized for its colorful foliage, which comes in shades of green, yellow, pink, red, and maroon. Coleus varieties can range from one to several feet in height. They can be used in hanging baskets, containers on patios, or in landscape beds. Coleus prefers partial shade and you can pinch the growing stems of young plants frequently to encourage dense foliage. Keep an eye out for mealybugs on coleus and use insecticidal soap if problems develop
