Residents of North Florida are no doubt familiar with camellias, the large, glossy-green-leaved shrub that flowers during the cooler seasons. Common varieties include Camellia sasanqua, which blooms from October through December (depending on variety), and Camellia japonica, which blooms January through March. Both make huge, showy blossoms that demand attention, with forms that range from wild-rose-like to stunning geometric formal patterns.
The popularity of these shrubs is not in doubt, but a cousin of theirs takes the prize as one of the most popular plants in the world. Not due to its flowers: this variety of camellia does bloom, but the leaves are most interesting to humans. It is grown in dozens of countries worldwide and global production is estimated at over $17 billion worth of these leaves. The primary product made from this plant is a beverage that is consumed more than any other drink except water. It is, of course, tea.

Camellia sinensis was named by botanist Carl Linnaeus, “Camellia” to honor another botanist, Rev. Georg Kamel, who really had nothing to do with the plant at all, and “sinensis”, which means “from China”. You may be able to deduce where tea is native to.
The tea plant prefers temperatures from 65 to 86 degrees Fahrenheit, doing well in zones 7-9. It can survive freezing or slightly-below-freezing temperatures, though leaves may be damaged by frost. It enjoys moist conditions, needing around 50 inches of rainfall per year. China tea (variety sinensis), which produces smaller, more serrated leaves, prefers more light than Assam types (variety assamica), which have larger, less serrated leaves. Either variety can be grown as a shrub or small tree.
Propagation may be accomplished either by seed or cuttings; cuttings are the preferred method for reproduction, as seeds must be germinated before the seed coat hardens for best results. Caring for tea plants once established involves more frequent but light fertilization, mulching, and regular scouting for pests. Camellia sinensis is susceptible to mites, thrips, scale insects, and aphids, all of which are present in large numbers in our area. Luckily, most of these problems can be solved with an application of either insecticidal soap or horticultural oil, if control is even necessary.
Once a tea plant is large enough to harvest leaves from, it is the new growth which is plucked. The top 2-3 leaves are used either fresh or fermented for a period of time before they are brewed. Green tea comes from the fresh leaves of China type tea plants, while either China or Assam types may be used to make black tea. Black tea leaves are picked, wilted or crushed, and allowed to ferment. Fermentation darkens the leaves and is halted by heating, which also serves to dry the leaves for storage.
Turfgrass lawns are popular. Homes and businesses alike often have at least some portion of their landscape dedicated to turf, and while it is often maligned, turfgrass does have some benefits when used and managed responsibly.

Detractors of lawns may argue that lawn maintenance uses water, gasoline (for mowers), and pesticides, all while contributing little to the environment. The varieties of grass we use in the Florida panhandle are not native to the area, with the possible exception of St. Augustinegrass. Planting anything – and especially non-native plants – in a monoculture limits biodiversity and does not support native wildlife. These complaints may be valid in cases, but this does not mean there is no room for turfgrass in the landscape. Instead, it is important to design landscapes appropriately and maintain lawns sustainably. The ideal of a lush, completely weed and insect free, beautifully green all year long, neatly trimmed magazine-cover style swath of grass is unrealistic.
That being said, what are lawns useful for? What are the benefits of turfgrass?
When managed properly, turfgrass can be used for numerous beneficial reasons. Grass is a plant, which means that it has roots to stabilize soil, slow runoff, and filter water. It keeps down dust, mitigates heat, and can outcompete unwanted weeds. It is useful as a surface for recreation, and can add aesthetic value to a landscape. Turf does, in fact, support wildlife to a certain degree as well, as the insects that live in and feed on it can serve as food for birds and other animals.
Improper irrigation can cause big problems with turf and lead to wasted water, but turf can help to slow down runoff and absorb excess nutrients.
Artificial turf is sometimes considered as an alternative to grass, but the differences can serve as an example of the benefits of turf. Artificial turf can heat up in the hot Florida sun. Where it is used on athletic fields, it may need to be irrigated to both cool it and keep dust down. The water used for this has much more opportunity to run off the site, as the artificial turf has no roots to slow it down. Turfgrass is also much softer than its man-made replacements; sports fields with artificial turf have a higher incidence of injury than those planted with grass.
Lawns must be managed well, however, as has been stated before. Proper species selection (whether bahia, centipede, Bermuda, St. Augustine, or Zoysia), establishment, irrigation, fertilization, and mowing practices all contribute to making turfgrass a sustainable option. You can find information on all of these in our EDIS publications, which are linked to above, or contact your local Extension office for help. If turfgrass still seems like an unpalatable option, you can also find information on turfgrass alternatives and more on Florida Friendly Landscaping. Keep your expectations reasonable and your landscapes sustainable!
There are numerous insects and insect relatives that can produce webbing, and webbing can be a sign that something unwanted is near. Arachnophobes might grow uneasy at the sight of a spiderweb, and gardeners might frown to see the tiny filaments that spider mites spin. Tree lovers might assume that webs on a tree are a sign that caterpillars such as the eastern tent caterpillar have taken up residence. But what about webs on a tree trunk?

If you come across a tree trunk coated in silk, chances are you’re looking at the work of a bark louse. Also known as psocids or tree cattle, these little insects eat all the stuff that sticks to a tree’s bark. Lichen, moss, algae, and dead bark can all end up as meals for a hungry bark louse. The good news is that while lichens don’t hurt trees, neither do bark lice!
Bark lice spin their webbing as protection from predators. They often produce large quantities of webbing, because there are often large quantities of bark lice present. The name ‘tree cattle’ comes from the fact that they form these large colonies, and move in a manner similar to cattle in groups. While swirling swarms of creepy-crawlies rarely make people feel at ease, don’t worry about these. Acting as a sort of clean-up crew, they will do their work, grow and mature, and move elsewhere by themselves.
There are often several generations of bark lice each year in Florida, so they may reoccur. No control is needed for these insects, though if leftover webbing is considered aesthetically unpleasing it can be removed by spraying with a sharp jet of water. For more information about bark lice, see our EDIS publication at https://edis.ifas.ufl.edu/publication/IN553.

Unlike areas with cooler climates, North Florida’s weather is a bit of a rollercoaster. Where the traditional four seasons allow for one growing season, the panhandle’s temperature changes create two growing seasons – spring and fall. During the winter, temperatures fall too low to keep plants happy, so those who expect to grow tropical plants in Florida may be disappointed. During the summer, the heat and humidity climb to levels that even plants can find stressful! Many of our vegetable crops simply can’t handle the extremes and wither away.
There are a few edible plants we can grow, however, that don’t seem to mind the hot weather. If you simply can’t live without a productive garden during the summer, you might consider trying these:
Also called Southern peas, black-eyed peas, or field peas, these are known for their ability to produce a crop despite the harshest of conditions. Actually a bean rather than a pea, they take 65 to 125 days to grow to full maturity, depending on variety. Because they are a nitogen-fixing legume, they have also been used as a cover crop.

Popular in Asian countries, Malabar spinach is actually a vining plant unrelated to true spinach. It grows quickly and is edible both raw and cooked, though some people may not appreciate its mucilaginous texture. Similar to okra’s sliminess, this quality does make it useful for thickening soups. Malabar spinach may be propagated from seed or by cuttings, which root easily. The plant also produces berries which, while not toxic, have very little flavor and tend to stain whatever they touch.
A traditional Southern favorite, okra takes the heat and keeps producing. Related to cotton and hibiscus, it grows pods that are ready to harvest after 60-70 days. Seeds have a tough exterior and need to be soaked overnight before planting. Harvest every couple of days at least for best results, as pods that grow too large become tough and fibrous.
Though they may need extra attention paid to them due to their attractiveness to pests, Seminole pumpkins are a great option for a summer planting. Similar to butternut squash, these cucurbits aren’t your traditional carving pumpkin, but they make great eating. Give them plenty of room to spread out in a sunny space. They take 120 days after planting before they’re ready to harvest, and their thick skin allows them to be stored for a long time after.
Does well in sandy soil? Check. Doesn’t mind the heat? Check. Sweet potatoes are great for our neck of the woods. Start out with disease-free slips for best results, and pick varieties such as ‘Beauregard’ that do well in our area.
Related to cowpeas, yardlong beans grow on a climbing vine. The beans themselves, as the name suggests, are contained in a pod that can reach 36 inches in length. These can be picked and cooked much like green beans while the pods are still tender.
When people think of livestock, honeybees may not be the first thing that comes to mind. Bees are, however, a very significant part of agriculture. It is estimated that 30% of the crops we use for food are pollinated by honeybees. That’s around $15 billion of crops! On top of that, these hardworking insects also produce honey, wax, and other products that we can use.
For those who want to get into the world of beekeeping, it can be a challenge to absorb all the information that’s out there. Thankfully, there are resources out there to assist. If you or someone you know are interested in apiculture, you might try:
Online resources. The University of Florida (UF) publishes research-based information in its EDIS publications. For topics relating to beekeeping specifically, you can go here: https://edis.ifas.ufl.edu/entity/topic/beekeeping. From there you can find links to specific publications, such as the Florida Beekeeping Management Calendar and much more. UF also has a Honey Bee Research and Extension Lab with online resources about their Master Beekeeper program and Bee College at https://entnemdept.ufl.edu/honey-bee/.
The American Beekeeping Federation maintains a website with tons of information on beekeeping at https://www.abfnet.org/. From there you can join the federation, find local groups, and find nationwide educational opportunities and resources for beekeepers.
The Florida Department of Agriculture and Consumer Services (FDACS) requires beekeepers to register hives. You can find information on that here: https://www.fdacs.gov/Agriculture-Industry/Bees-Apiary/Apiary-Inspection. This site has a lot of extra information on beekeeping and links to other resources as well!
Local Resources. While digital sources of information can help, nothing can take the place of simply having other beekeepers to go to for answers. Local beekeeping organizations are a great place to start. Listed by county, here are some from across the panhandle:
