Too often, would be gardeners travel to exotic locales, become intoxicated with the beautiful floral display of Plumeria, Jatropha, Bird of Paradise and Bougainvillea, and come home with visions of homemade leis picked from the garden dancing in their heads. As anyone who has attempted to grow any of the aforementioned plants in the Panhandle will tell you though, fulfilling those visions in the landscape are easier said than done! However, not all is lost for the gardener wanting to bring the tropics home. A tropical feel in the landscape can be achieved, you just have to look beyond the aforementioned flowering plants that will have long since succumbed to winter frost by the time they mature and begin flowering and instead to tropical foliage plants that can be enjoyed for a season and easily (cheaply too!) replaced the following spring. Of all the tropical foliage options available for Panhandle landscapes, my favorite is the Ti Plant, sometimes called Hawaiian Ti.
Ti Plant foliage
Even if you have never heard of Ti, you have probably seen it. The strap like, 12-18” long, purple and pink striped leaves are hard to miss and add an unmistakable tropical flair in the landscape! Ti Plants grow generally in single, unbranched stalks, though most commercial growers combine several plants into a single pot to give a bushy, multi trunked appearance that looks more appealing on a retail nursery bench. These plants will easily reach 4-6’ in height in a single warm season, providing a powerful punch of pink/purple all summer long. In addition to its considerable attractiveness, Ti boasts a cosmopolitan constitution, as it will grow in sun or shade, outside or inside. Of course, some cultural do’s apply to Ti broadly, regardless of where it is grown, as well as a few don’ts.
In general, Ti will be more colorful in brighter light. Though it grows well in shade, its leaves tend to lose their luster and fade to a dull purple in full shade. Similarly, though it will survive in full, all day sun, Ti’s foliage tends to bleach a bit in these conditions and can turn a whitish gray. It is best to shoot for somewhere in the middle for the most vivid foliage color. If growing indoors, give Ti as much light as you can. If growing outdoors, full sun through midafternoon is appropriate, as is bright shade throughout the day. Be sure to give Ti plants consistent moisture, as they will readily wilt down under prolonged drought conditions. As with watering, Ti prefers a consistently fertile soil and will appreciate a topdressing of a complete, slow release fertilizer (made by Osmocote, Harrell’s and others) at planting, with a follow up application 60-90 days later (possibly more frequently depending on temperature and frequency of watering).

Though Ti performs well planted in the ground in Northwest Florida as an annual specimen to brighten a border (think of it like a supersized Coleus), it really gets to shine in large, mixed containers. Ti’s upright growth habit and traffic stopping color make it the perfect thriller in the widely used “thriller, filler, spiller” container design. Because Ti can grow quite large relative to other common container plants, a large 20-45 gallon container is necessary to facilitate optimum root growth and plant development. If a smaller container is chosen, water management will become an issue as the Ti plant’s root mass will quickly crowd the container. I prefer glazed ceramic or concrete containers as these are often painted in bright colors that complement Ti’s foliage, do not allow as much air exchange as terra cotta planters (soil in terra cotta containers dry very quickly in hot, dry weather), and are heavy enough that tall Ti plants won’t cause them to blow over in windy conditions. Mix smaller, mounding filler plants and trailing spiller plants under and around Ti in containers. For a striking contrast in color, choose companion plants in white, yellow, orange or chartreuse (remember, plants don’t have to flower to be colorful, vivid foliage plants like coleus or caladium work too!).
Regardless of how you use Ti Plant, you’ll find it to be one of the most high value color plants in the landscape. Plant one today and happy gardening!
Each time I travel to central and south Florida and observe the wonderfully flamboyant tropical flora, I am reminded of the unique and frustrating climatic characteristics of Northwest Florida. Our weather is tropical enough through the summer to sustain virtually everything our friends to the south grow, but winters north of the Big Bend are just cold enough to prevent long-term success with most tropical species. However, the genus that is maybe most synonymous with tropical color, the Hibiscus (it even has its own texting emoji!), contains several species that are hardy through our winters. The best landscape plant of these hardy Hibiscus species is creatively (sarcasm) called Hardy Hibiscus or Giant Rose Mallow (Hibiscus moscheutos) and is an absolute star in the Panhandle, bringing the beauty of the tropics to your yard!

Rose Mallow is a native perennial species that occurs in sunny wetlands across the eastern U.S. This species can grow 7-8’ in height in its natural, unimproved state and possesses the largest flowers of any hardy perennial, some varieties easily eclipse 12” in diameter. Rose Mallows bloom through the heat of our long summers and return reliably each winter unfazed by frost. The flowers also happen to be a favorite of butterflies and hummingbirds and bring beneficial wildlife to the landscape. These characteristics and the trend towards the use of pollinator friendly, low-maintenance native perennials in landscapes quickly made Rose Mallow a jewel for plant breeders and now virtually all major horticultural brands have a line of Hardy Hibiscus available at garden centers, in varying sizes, flower color and leaf color/form. Recent breeding efforts have focused on introducing plants with enormous, richly colored flowers held on compact plants with attractive foliage. The results have yielded two series and three individual cultivars that I consider superior selections and are more than worthy of inclusion in your garden:
- Summerific® Series by Proven Winners. This series is comprised of four robust (up to 5’ in height) cultivars, ‘Cherry Cheesecake’ (bicolor magenta and white flowers), ‘Berry Awesome’ (purplish lavender flowers), ‘Cranberry Crush’ (a red you really have to see to believe), and ‘Perfect Storm’ (notable for its deep purple foliage).
- Luna Series by Monrovia. This series is notable for its ultra-compact (3’ in height or less) size and characteristically large flowers. It is also composed of four cultivars, ‘Luna Red’ (deep red), ‘Luna Blush’ (white, fading to pink near flower margins), ‘Luna Pink Swirl’ (pictured and my favorite, bicolor swirly flowers), and ‘Luna White’ (white with a red center).

- ‘Starry Starry Night’ by Walter’s Gardens. (Pictured) This cultivar combines dark purple to black leaves with swirled pale and dark pink flowers. It has performed very well in my landscape and if I could only grow one, this might be it.
- ‘Lord Baltimore.’ The classic, large growing cultivar with bright red flowers that is widely available and easily found. An oldie (introduced in 1955) but a goodie.
- ‘Midnight Marvel’ by Walter’s Gardens. A “hot off the press” new cultivar that is currently difficult to find due to popularity, though some online outlets have them available in small sizes. This one is worth your patience. Sporting deep red blooms on near black foliage, there’s nothing else like it in the landscape.
In addition to being gorgeous plants, Rose Mallows are extremely versatile in the landscape and could not be easier to grow. Because the size varies so greatly (from the diminutive 30” tall ‘Luna’ series to the 8’ tall unimproved species), there really is a place for one in every garden. I like to use the smaller cultivars in large containers to facilitate moving them around where their floral display has the greatest impact or to create a tropical effect where in ground plantings are not an option (pool decks, patios, etc). The larger cultivars make spectacular specimen plantings in perennial and shrub beds and even make a really dense, striking hedge (just know they disappear in the winter). Be sure to give them as much sun as possible, as this will enhance the number of flowers on each plant and darken the foliage on the cultivars with purplish/black leaves. Too little sun will result in fewer flowers and lighter green foliage. As wetland plants, Rose Mallows enjoy regular water, either from rainfall or irrigation; they will let you know when they need it – their large leaves readily wilt under drought stress, somewhat like Hydrangea.
For low-maintenance, native, pollinator friendly, cold-hardy tropical color, you need look no further than Rose Mallow. These perennial shrubs come in all sizes and colors and fit any landscape! Look for the above listed series and cultivars at better garden centers and online retailers and enjoy the oohs and ahhs elicited when people first get a glimpse of Hardy Hibiscus in your landscape! Happy Gardening!

Patience, warmer soil temperature and correct lawn management will solve many spring lawn problems.
Many spring dead spots in lawns are caused by something that happened the previous growing season or winter. For example, a late application of a high-nitrogen fertilizer can decrease winter survival. It’s best to not fertilize our lawns after early September.
An insect or disease problem during fall many times goes unseen as the grass is beginning to go dormant. The following spring, as the lawn begins to green up, evidence of a fall pest is clearly visible by brown dead, grass. The pest may not be present or active during spring.
Poor maintenance practices may be to blame for spring dead spots. Over-watering, shallow watering (watering frequently for short periods), mowing too low, too much fertilizer and herbicide injury can result in poor lawn performance come springtime.
Regardless of cause, problem areas within lawns are slow to recover during spring due to frequent cool night temperatures. Frequent cool nights keep the root zone cool.
Cool soil temperature doesn’t allow rapid root regeneration in spring, which inhibits top growth in your lawn. Cool soil also decreases availability of some needed nutrients. For example, poor availability of iron because of cool soil is a common cause for bright yellow areas within lawns, especially in centipedegrass. Cool soil also decreases availability of phosphorus and potassium, which can result in reddish-purple grass blades, intermingled throughout the yard. As soil temperature increases, availability of nutrients improves and the yellow and purple areas turn green.
Have patience with your lawn and follow good maintenance practices this spring. Provide ½ to 1 inch of water when the grass shows signs of wilt. Fertilize and lime based on the results of a reliable soil test. And, mow at a high setting. Good lawn maintenance info is provided at the YourFloridaLawn website.
Consistently warmer nights will allow the soil temperature to warm, which will improve turf root growth, nutrient availability and lawn recovery. During many years in North Florida, it’s well into the month of May before our lawns begin to recover.
If the lawn has not made a comeback by late spring or early summer, it may be time to consider reworking and replanting the dead areas or maybe consider replacing them with something other than grass, if practical.
After you have chosen the right fertilizer, fungicide, herbicide or insecticide to apply to your landscape, the question becomes: how much do I buy? Labels on these products will tell you how many square feet it will cover – so that leads to the next question: how many square feet of lawn do I have?
Here’s an easy way to determine your square footage. This online tool from Sod Solutions uses GIS mapping to figure it out from the comfort of your lounge chair.
