Edible landscaping has become a trend for many gardening enthusiasts. A combination of edible plants along with traditional ornamentals can create an artful presentation. There are some challenges when designing such a landscape, but in those challenges opportunities’ may be found. One of the most difficult challenges is making sure your garden or landscape is healthy and vibrant year-round since many edibles are short-lived annuals. These include plants such as eggplant, pepper, lettuce, artichoke and some annual herbs. There is a solution to this concern. First, know your edible plant’s propagation and maturity months. This way you can offset plantings to ensure color in your landscape. Another key measure is to mix some evergreen ornamentals in with short season edibles and long season edibles. Examples of long season edibles include berry shrubs, fruit trees and biennial or perennial herbs.

When designing your edible landscape, think about style and theme to help guide you through the process. A formal design has more straight edges and geometric shapes, whereas the more natural approach has meandering edges and irregular shapes. A color scheme in harmony is very important. Remember, an edible landscape should not just be a production food garden but a visual treat. The goal is not to grow a high yield garden, but only to produce supplemental edibles to make the endeavor worthwhile.
Dr. Gail Hansen, Associate Professor of Environmental Horticulture at the University of Florida, has developed twelve ideas when creating an edible landscape:
- Combine reliable, low-maintenance ornamental with edible plants. Use evergreen ornamentals to maintain enough green structure, so that potential cool season bare spots are not visual.
- Use support structures for an artistic effect and to assist in growth of some plants. Trellises, arbors and even tomato cages are some examples that can be used.
- Use containers in areas to keep the landscape more organized. Planters will also help in maintenance, as plants will be easier to reach and the soil will be easier to manage.
- Create some hard edges in your landscape. Raised beds, garden walls and borders will give defining lines to the landscape and promote a clean appearance.
- A pathway through the landscape will both provide an access to plants and give an inviting appeal. Brick pavers, gravel and mulch are good examples of pathway material.
- Remember color is key. Create a visually pleasing combination of plant color, form, texture and sizes.
- Always start by keeping it simple. So, start small and simple. Then, you can begin filling in the landscape.
- Look for one unique feature to create an added interest to you landscape and provide growth to plants. This could be a shade house for ferns and other hanging baskets or a hay bale, where lettuce, tomatoes or peppers could grow upon.
- Select appealing and easy to grow plants that you want to eat!
- Let plants reach maturity before taking them out of the landscape. For example, rainbow chard will grow larger, if allowed to continue to grow after seed has been produced.
- Use the Florida-Friendly Landscaping principle, “Right Plant, Right Place”, when adding edibles to your landscape. Match the growing needs with the most suitable location.
- Consider your location and layout for irrigation. All plants need some degree of water. An above ground drip irrigation system is usually the most flexible and adjustable irrigation method in regards to overall plant watering needs in a landscape.
Following Dr. Hansen’s ideas will help you create the edible landscape of your dreams. For more information on edible landscaping, please contact your local county extension office for more details.

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.

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.

Arbor Day has a 145-year history, started in Nebraska by a nature-loving newspaper editor named J. Sterling Morton who recognized the many valuable services trees provide. The first Arbor Day was such a big success that Mr. Morton’s idea quickly spread nationwide–particularly with children planting trees on school grounds and caring for them throughout the year. Now, Arbor Day is celebrated around the world in more than 30 countries, including every continent but Antarctica. We humans often form emotional attachments to trees, planting them at the beginning of a marriage, birth of a child, or death of a loved one. Trees have tremendous symbolic value within cultures and religions worldwide, so it only makes sense that people around the world have embraced the idea of celebrating a holiday focused solely on trees.

In addition to their aesthetic beauty and valuable shade in the hot summers, trees provide countless benefits: wood and paper products, nut and fruit production, wildlife habitat, stormwater uptake, soil stabilization, carbon dioxide intake, and oxygen production. New research is even showing that trees can communicate throughout a forest, sharing “information” and nutrients through a deeply connected network of roots and fungi that can increase the resiliency of an entire forest population. And if you’re curious of the actual dollar value of a single tree, the handy online calculator at TreeBenefits.com can give you an approximate lifetime value of a one growing in your own backyard.
While national Arbor Day is held the last Friday in April, Arbor Day in Florida is always the third Friday of January. Due to our geographical location further south than most of the country, our primary planting season is during our relatively mild winters. Trees have the opportunity during cooler months to establish roots without the high demands of the warm growing season in spring and summer.
To commemorate Arbor Day, many local communities will host tree giveaways, plantings, and public ceremonies. In the western Panhandle, the Florida Forest Service, UF/IFAS Extension, and local municipalities have partnered for several events, listed here. As the Chinese proverb goes, “The best time to plant a tree was twenty years ago. The second best time is now.”
For more information on local Arbor Day events and tree giveaways in your area, contact your local Extension Office or County Forester!

A new tree or shrub is an investment for the future. When we pick an ornamental plant, we have the hope that it will survive for many years and offer seasons of beauty that enhance our landscape. Time is often spent picking a suitable spot, preparing the planting hole, and watering until establishment. We give it the best of care to make certain that our new plant becomes a more or less permanent feature.
With all of our tender love and care for new ornamentals, there is one important practice that we may neglect. Most homeowners purchase plants in containers and it is common to find root balls with circling roots. If any root ball problems are not addressed before installation, the life of your plant may be shorter than you want.

The best practice for woody ornamentals is to cut any roots that are circling the trunk or container. Homeowners may slice downward through the root ball around the entire plant. For shrubs, it is recommended to shave off “the entire outside periphery of the rootball” to eliminate circling roots. These practices allow the root system to grow outward into new soil and greatly reduce the possibility of girdling roots killing your plants years after establishment.
