Springtime brings small but very pretty red blooms on an outstanding native shrub/small tree, Florida red anise (Illicium floridanum). It occurs naturally in the wild in the central and western panhandle of Florida and west along the gulf coast into Louisiana. Its natural environment is in the understory along streams and in rich, wooded areas.
This is a great shrub for a part shade to shady and moist area in your landscape. The dense foliage, dark green leaves and the fact that it is evergreen all year makes it a great choice for an informal hedge. Plan for it to grow to a maximum height of 12 to 15 feet.

The leaves have a licorice-like aroma when crushed but this is NOT the species that gives us the edible culinary anise. Maybe it is that aroma that makes this a relatively pest-free plant!
Yellow anise (Illicium parviflorum) is a very similar native shrub but has small yellow flowers and adapts better to a drier environment. The native range of the yellow anise is north central Florida.

Do you have more acorns than you know what to do with? When oaks produce loads of acorns, it sometimes is called a “mast” year. Do you remember the oak tree pollen and all those catkins that fell from oaks earlier in spring?
Catkins are the male flowers in oaks. Some people refer to them as tassels or worms. The airborne pollen from these catkins were part of the reproductive process in fertilizing the female oak flowers that ultimately resulted in all of these acorns. Oaks produce separate male and female flowers on the same tree. Female flowers in oaks are very small. You’d have to look very close to see them. Many oaks did well in their reproductive efforts this spring. Acorns are oak seeds. This entire process is part of the cycle of life.
There are theories about mast years, wildlife’s use of these acorns and what gardeners can expect next year as a result of this year’s abundant acorn crop. Timing of mast years is still a mystery. Numerous theories exist ranging from weather to geography to the life cycles of predators.
The most likely reason for high production seems to be weather-related. When oak trees have favorable weather at the time of oak flowering and good growing conditions, the mast seems to be increased.
But mast years happen irregularly, making it difficult to understand what causes a mast year. Heavy acorn production can occur twice in a row or it might be separated by several years or more. There’s no good way to predict it.
Mast years are important to wildlife, as acorns are an important food for many animal species. In low crop years, birthrate for some wildlife species, such as squirrels, will decline the following year. This also may involve increased competition for food and survival rates. The recent crop means that more young are likely to be produced by animals that forage for acorns.
Wildlife play a big role in forest regeneration. When acorns drop out of oaks, many animals help distribute these seeds. Squirrels can bury hundreds of acorns. Some of these acorns germinate and grow to become the next generation of oak trees. Some will be eaten by birds, bears, deer, rodents, including squirrels, and other wildlife. Rodents are in turn eaten by carnivores and deer browsing shapes which kinds of plants become established and survive. All those acorns have far-reaching impact on wildlife and our forests.
So, try to keep this in mind as you are fussing with all those acorns in your lawn and landscape this season.

A common diagnostic service offered at your local UF/IFAS Extension office is plant identification. Whether you need a persistent weed identified so you can implement a management program or you need to identify an ornamental plant and get care recommendations, we can help!
In the past, we were reliant on people to bring a sample to the office or schedule a site visit, neither of which is very practical in today’s busy world. With the recent widespread availability of digital photography, even the least technology savvy person can usually email photos themselves or they have a friend or family member who can assist.
If you need to send pictures to a volunteer or extension agent it’s important that you are able to capture the features that are key to proper identification. Here are some guidelines you can use to ensure you gather the information we need to help you.
Entire plant – seeing the size, shape, and growth habit (upright, trailing, vining, etc.) is a great place to begin. This will help us eliminate whole categories of plants and know where to start.
Stems/trunks – to many observers stems all look the same, but to someone familiar with plant anatomy telltale features such as raised lenticels, thorns, wings, or exfoliating bark can be very useful. Even if it doesn’t look unique to you, please be sure to send a picture of stems and the trunk.
Leaves – leaf color, size and shape is important, but also how the leaves are attached to the stem is a critical identification feature. There are many plants that have ½ inch long dark green leaves, but the way they are arranged, leaf margin (edges), and vein patterns are all used to confirm identification. Take several leaf photos including at least one with some type of item for scale such as a small ruler or a common object like a coin or ballpoint pen; this helps us determine size. Take a picture that shows how leaves are attached to stems – being able to see if leaves are in pairs, staggered, or whorled around a stem is also important. Flip the leaf over and take a picture of the underside, some plants have distinctive veins or hairs on the bottom surface that may not be visible in a picture taken from above.
Flowers – if flowers are present, include overall picture so the viewer can see where it is located within the plant canopy along with a picture close enough to show structure.
Fruit – fruit are also good identification pictures and these should accompany something for scale to help estimate size.
Any additional information you are able to provide can help – if the plant is not flowering but you remember that it has white, fragrant flowers in June, make sure to include that in your description.
Learning what plants you have in your landscape will help you use your time and resources more efficiently in caring for you yard. Contact your local UF/IFAS Extension office to find out who to send requests for plant id.

During a recent hike through wooded property in Walton County, our Florida Master Naturalist class came across a stunning example of an American Beech tree (Fagus grandifolia). As we looked closely at its thick, sinewy trunk (often compared to an elephant’s skin), the bark changed hues from a deep red to silvery gray and brown. A hardwood, it has been used over the years to make furniture, railroad ties, and beer barrels. Like many of the local hardwood species, beech wood holds up to decay when exposed to water and early settlers used it to build mills and water wheels.

During the growing season, the beech tree can be identified by its distinctive dark green, tooth-edged leaves. Beeches are deciduous but have the unique quality of usually keeping dead leaves on their branches all winter, which also helps with identification in the forest.
The most fascinating observation, to me, was the series of tightly swirled branch buds ready to sprout at the tips of each new branch. So pointed that they’re easily confused as thorns, these long protrusions will eventually grow into new branches.
These four buds formed as an “emergency” response to the branch being cut and will eventually replace it. Photo credit: Carrie Stevenson
At the end of one branch that had been cut, the tree’s internal “emergency response” system formed four new immature branches, which had the intimidating appearance of a claw. Eventually, one of these buds will outcompete the others and grow into a new branch.
Beeches are of course known for the beech nut, eaten by humans and wildlife alike. If you’re considering a beech for a home landscape, be sure you have a wide open space with moist soil, as a mature beech can grow up to 75 feet high and 40-60 feet wide. Its low branches create a lot of shade, so understory plants are usually unnecessary or even impossible to grow.
For more information on these interesting native trees and others like it, contact your local UF IFAS Extension Office or visit the UF Landscape Horticulture page.

Monarch butterfly on dense blazing star (Liatris spicata var. spicata).
Beverly Turner, Jackson Minnesota, Bugwood.org
Each fall, nature puts on a brilliant show of color throughout the United States. As the temperatures drop, autumn encourages the “leaf peepers” to hit the road in search of the red-, yellow- and orange-colored leaves of the northern deciduous trees.
In Northwest Florida the color of autumn isn’t just from trees. The reds, purples, yellow and white blooms and berries that appear on many native plants add spectacular color to the landscape. American Beautyberry, Callicarpa americana, is loaded with royal-colored fruit that will persist all winter long. Whispy pinkish-cream colored seedheads look like mist atop Purple Lovegrass, Eragrostis spectabilis and Muhlygrass, Muhlenbergia capillaris.
The Monarchs and other butterfly species flock to the creamy white “fluff” that covers Saltbrush, Baccharis halimifolia. But, yellow is by far the dominant fall flower color. With all the Goldenrod, Solidago spp., Narrowleaf Sunflower, Helianthus angustifolius and Tickseed, Coreopsis spp., the roadsides are golden. When driving the roads it’s nearly impossible to not see the bright yellows in the ditches and along the wood’s edge. Golden Asters (Chrysopsis spp.), Tickseeds (Coreopsis spp.), Silkgrasses (Pityopsis spp.), Sunflowers (Helianthus spp.) and Goldenrods (Solidago spp.) are displaying their petals of gold at every turn. These wildflowers are all members of the Aster family, one of the largest plant families in the world. For most, envisioning an Aster means a flower that looks like a daisy. While many are daisy-like in structure, others lack the petals and appear more like cascading sprays.
So if you are one of the many “hitting the road in search of fall color”, head to open areas. For wildflowers, that means rural locations with limited homes and businesses. Forested areas and non-grazed pastures typically have showy displays, especially when a spring burn was performed earlier in the year. Peeking out from the woods edge are the small red trumpet-shaped blooms of Red Basil, Calamintha coccinea and tall purple spikes of Gayfeather, Liatris spp.
Visit the Florida Wildflower Foundation website, www.flawildflowers.org/bloom.php, to see both what’s in bloom and the locations of the state’s prime viewing areas. These are all native wildflowers that can be obtained through seed companies. Many are also available as potted plants at the local nurseries. Read the name carefully though. There are cultivated varieties that may appear or perform differently than those that naturally occur in Northwest Florida.
