Sensory gardens are a great way to involve children and people with special needs with gardening. Gardens provide a no-judgement zone for creative expression and allow us to get down in the dirt every now and then. Because sensory gardens are designed to be appreciated by more than just the sense of sight, they are an approachable way for disabled and non-disabled users alike. By engaging taste, feel, smell, hearing, and more, sensory gardens allow visitors of all ages and circumstances to engage in gardening.
To make your own sensory garden, think about what feeling you would like to experience while visiting your garden. Do you want a calm healing place of introspection or perhaps a vibrant playful area for engaged learning in nature? Having a theme can help you choose the different elements you would like to include in your sensory garden, which can be an entire yard or as small as a container. They are being used more and more in memory care units of nursing homes as well as preschools and elementary schools, but you can make your own right at home.

The sound of moving water is calming to many, so a small fountain can be a great addition to your sensory garden. It will also benefit local wildlife by offering them a small watering hole. As long as the water is moving, mosquitos should not be a problem, but mosquito dunks or even the incorporation of mosquito fish are easy solutions to solving mosquito problems in small ponds or fountains. Some plants to consider for their sounds include false indigo (Baptisia australis), switchgrass (Panicum virgatum), and mountain oats (Chasmanthium latifolium). False indigo produces seed pods great for rattling, and when it is windy, switchgrass and mountain oats provide a gentle rustle.
A variety of textures offers the gardener a safe place to interact with nature without worrying about the dangers of poison ivy and other plant irritants. Plants like muhly grass (Muhlenbergia capillaris) offer a multitude of interactions as they sway in the wind, have bright white and pink blooms, and can be braided together in a variety of patterns. The native sunshine mimosa (Mimosa strigillosa) is a low growing ground cover that puts out pink powderpuff flowers and folds up when touched. Some other plants to explore by touch are lamb’s ear (Stachys byzantine), maiden grass (Miscanthus sinensis), the mildly dangerous points of aloe, and the many textures of southern magnolia (Magnolia grandiflora).
There are plenty of smelly plants to entice your nose in the garden. From rosemary to dill, mint and beyond, many herbs do very well here in the Florida Panhandle. Lemon balm and lemongrass bring a punch of citrus without the need for a big citrus tree. Beyond herbs, pine needles give a resinous scent when compressed, gardenias offer heavy sweetness from their voluminous white blooms, and sweet almond verbena (Aloysia virgata) delights with a vanilla almond aroma that carries pleasantly in the wind.

When it comes to tasting in a sensory garden, fruits and vegetables are an obvious choice. Plenty of annual vegetables can be grown year-round, from leafy greens in the fall, winter, and early spring, to tomatoes and peppers in the summer. Blackberries are an easy to grow favorite in this part of the state, are available as thornless varieties, and take well to growing on a trellis in small spaces. A great edible that many children favor in the Demonstration Garden at the Leon County Extension Office is cranberry hibiscus. The bright red leaves of new growth are a sweet and sour treat they equate to Sour Patch Kids candy. The older leaves can be added into stir fries and salads and the flowers can be cooked into a syrup for making purple lemonade. Herbs can be used for their taste factor as well. But if your sensory garden will be visited by the general public without supervision, I recommend clear delineation for the tasting area so that no one eats anything unpalatable or poisonous by accident.
When setting up your sensory garden, be sure to involve your intended audience. Small children thrive when given a job to do and will enjoy planting sweet herbs alongside you. Even regular maintenance of the garden can involve the participants you hope to engage. The simple acts of weeding and watering can foster a sense of responsibility and empowerment as the visitors gain sensory enrichment through these activities and see the fruits of their labor with time.

Mid-summer in the Panhandle vegetable garden is prime time to be offering up a great crop of eggplant. This is one of my favorite summertime fruits to grow! (Yes, it is botanically speaking a ‘fruit’ and not a ‘vegetable’.)
Many home gardeners are familiar with the standard ‘Black Beauty’ variety that produces large plump fruit, but there are many other eggplant varieties to try. Take a look at Heirloom Eggplant Varieties in Florida to get some ideas. Gardeners can access dozens of varieties through online seed vendors. Eggplants can be dark purple, purple-striped, pale purple, white, green and even orange. They come in all shapes and sizes and all are delicious to eat, j make sure you learn when to harvest the variety you choose for optimum enjoyment. For example, the Turkish Orange illustrated in the photo should be picked before it turns all orange to avoid any bitterness.
In the panhandle, plant eggplant anytime February through August for harvest late spring through fall. Eggplant is in the nightshade (Solanaceae) family along with tomato, pepper, and potato. Keep that in mind when you are planning your garden for next year to avoid planting members of the same family in the same spot year after year, which encourages recurring disease and pest issues.
Eggplant loves rich soil and benefits from regular fertilization with commercial fertilizers or applications of compost. Eggplant is considered a long season crop and one can expect harvest to begin around 90-110 days after planting seed or 75-90 days if setting out transplants. Eggplant is, in general, more drought tolerant than tomato but it is still good practice keep them consistently moist and avoid letting them completely dry out. Also, while eggplant is self-pollinating, it is an excellent pollinator plant, as many species are attracted to the pretty blooms.
Eggplant is also relatively easy to grow, not generally requiring pruning or staking. Many of the same pests of tomato and pepper will also be attracted to eggplant. Be on the lookout for tomato hornworm and other caterpillar pests. For natural pest control methods, consult Natural Products for Managing Landscape and Garden Pests in Florida
As an avid gardener and plant collector you might think I’m hyper-aware of everything growing in my yard. Sadly, I’m just as busy and forgetful as the next person and don’t always remember what’s out there. The silver lining to the distracted auto-pilot life we find ourselves in is that occasionally you get brought back into the moment by a show stopping surprise in the garden.
Bleeding Heart Vine is one of those garden gems. Planted in the bright shade of a pair of oak trees in my Northwest Florida yard, the dark green foliage blends into the background most of the year, but when it flowers look out! Panicles of 5-20 white and red flowers brighten up the shady garden. As the flowers fade, they turn a deep mauve that is just as attractive as the fresh flowers.
Some vines can be aggressive growers, but in the Florida Panhandle Bleeding Heart Vine is a relatively slow grower reaching about 15 feet at maturity. It is classified as a twining vine, but may need a little help supporting itself on a trellis. This vine lacks tendrils or suckers that some vines use to attach to structures, which makes it a little easier to redirect if it starts to grow in an undesirable direction. Don’t want it to climb? Prune to stimulate branching and it gets more of a sprawling, bushy shape.
Bleeding Heart Vine prefers moist, well-drained soil and high humidity. It is hardy to 45°F and may need protection in the winter. Personal observations of this plant have shown stem dieback in the winter, but it has grown back for multiple years without protection in Northern Bay County.

To everyone’s delight, the blackberries are ripening in the Santa Rosa County Extension demonstration garden. The blackberry patch is a reliable perennial that continues to provide fresh berries year after year. Before you decide against them because you don’t want a thorny and painful hazard in your landscape, remember that there are thornless blackberry cultivars with fruit just as tasty as the old-fashioned thorny blackberry varieties. However, it is important to take care and make sure that the variety or cultivar you choose is adapted to our Florida climate and chill hours.

You can choose a blackberry variety from your local nursery or propagate some plants from a favorite blackberry grown by a friend or neighbor (with permission, of course). Methods of propagation include stem cuttings, root cuttings, tip layering and removing the suckers that arise from the roots.
Plant when the weather is cooler in winter and choose a sunny spot with good soil. Frequent irrigation is crucial during the establishment period and when the fruit is produced. Weed control with organic or plastic mulches is also important to the success of your blackberry patch.
For more information on blackberry cultivars, propagation and growing success please see the University of Florida publication The Blackberry.
My obsession with plants started with the purchase of my first house in Waverly, Alabama in the late 90s. I bought a house with seven acres and of that about 1.5 acres was a fenced yard. The landscape was not very appealing, so I was on a mission to make it beautiful yet functional for my dogs. The only problem was, as a new homeowner, I had very little expendable income for my burgeoning plant habit. This dilemma forced me to be a resourceful gardener.
Shop the discount rack at garden centers
Many retail garden centers (especially mixed use stores with limited plant space) will discount plants simply because they are no longer flowering. Plants look perfectly healthy but are just not considered “retail ready” anymore, so rather than hold them over until they bloom again and appeal to most shoppers the stores tend to mark them down.
Plants are either growing or they are dead, so it is common to find some outgrowing their container and are getting “potbound” which means the root system is outgrowing the pot. Potbound plants are hard to keep watered without wilting and the solutions are to transition to a larger pot or plant in the ground. Most garden centers are not equipped to pot up overgrown plants to larger containers, so the easier solution is to sell them quickly. If you purchase a plant with circling roots be sure to trim the bottom and score (slice) the root ball to encourage roots to spread laterally.
Avoid plants that appear diseased (leaf spots, brown stems, mushy parts, rotting odor) or have active feeding insect activity.
Compliment other gardeners’ plants
When you get gardeners together, they inevitably start swapping plants. I really don’t have an explanation for this other that good old southern hospitality, but I’ve noticed over the years that when you express appreciation of plants to other people they tend to end up in your own yard. Ask if you can take a pinch (for cuttings) or offer to divide a clump of crowded perennials and you are on your way to a trunk full of plant babies.
I can’t recommend this for multiple safety reasons, but I have been known to photographs plants in my travels then strike up a conversation with a homeowner who insisted I take one home.
Experiment with basic propagation techniques
Grow flowers from seed. Either purchase seeds (usually under $2/pack) or collect seed heads from spent flowers in your own garden. After flowers fade, allow them to set seed then either crush and distribute in other parts of your garden or store in a cool, dry place until you can swap with friends.
Division – clumping perennials such as daylilies, cast iron plant, iris or liriope can be dug up and cut into smaller pieces with a shovel or machete. You only need to be sure to have buds on top and roots on the bottom to make a new plant. Other plants create offshoots that can be removed from the parent plant. Examples of these are agave, cycads, and yucca.
Cuttings – the list of plants that can be propagated from stem cuttings is endless but a few that are very easy are crape myrtle, hydrangea, and coleus.
