‘Gumpo Pink’ flowers are 3 inches in diameter and are pink with purplish pink dots and occasional white blotches on petals.
In the times before re-blooming azaleas like Encore®, Bloom-A-Thon® and others, Satsuki azaleas were valued for late flowering that extended the azalea “bloom season”. Even with modern re-blooming azaleas, Satsuki azaleas still are appreciated as refined evergreen shrubs for the sophisticated garden or discerning plant collector.
“Satsuki” means “Fifth Month” in Japanese, corresponding to their flowering time in much of Japan. These azaleas were developed hundreds of years ago from their native Rhododendron indicum and R. eriocarpum. The Japanese selected cultivars more for their form and foliage than for flowering. These beloved plants were used in gardens as sheared boxwood-like hedges or pruned into rounded mounds that might resemble rocks or boulders in classical Japanese gardens. Their size and form also made them well adapted for training as bonsai. Most of the Satsuki azaleas in America were introduced in the 1930s by USDA.
Satsuki azaleas are small evergreen shrubs that flower in April and May in north Florida, long after most older type azaleas have finished. Satsuki azaleas also are known for producing large, mostly single flowers up to 5 inches in diameter in colors of white, pink, red, reddish orange and purple. Often the flowers will include stripes, edging, blotches, spots or flecks of contrasting colors (Sometimes all on the same plant!) with more than 20 different color patterns recorded.
Satsuki azaleas have an elegant subtle charm, quite unlike the flashy, over-the-top, heavy blooming all-at-once Southern Indica azaleas like ‘Formosa’ and ‘George L. Taber’. Typically, Satsuki azaleas display a few large blooms at a time, allowing one to better appreciate their size and color patterns as contrasted against their fine-textured, dark green leaves. To make up for a less boisterous display, Satsuki azaleas flower over a longer timeframe, averaging about 8 weeks, with some flowering an amazing 14 weeks. In another contrast, most Satsuki azaleas grow smaller in size, in my experience reaching about 3 feet tall and wide in a five-year timeframe. The rounded to lance-shaped leaves of Satsuki azaleas also are demure, ranging in length from just ½ inch to no more than 2 inches.
Satsuki azaleas enjoy the same conditions as most other azaleas: light shade and moist, rich, well-drained soil. Mulch regularly to maintain organic matter and help hold moisture. Fertilize lightly and keep the roots evenly moist. Minimal to no pruning is required. Satsuki azaleas also are well adapted to container culture. Their small size and fine textured leaves make these a favorite for bonsai enthusiasts since their small leaves, branching habit and mounded form naturally make them look like miniature mature “trees”.
Sources and Cultivars
Look for Satsuki azaleas in spring at garden centers or year-round at online nurseries. There are hundreds of cultivars but some popular types to look for include:
Gumpo Pink – 3-in. diameter light pink flowers with purplish pink dots and occasional white blotches
Gumpo White – 3-in. diameter white flowers with occasional pink flakes and light green blotches
Gyokushin – 3-in. diameter flowers are predominantly white but with light to dark pink dots and blotches
Higasa – flowers are 4 to 5 inches in diameter and are purplish pink with purple blotches
Shugetsu – also called ‘Autumn Moon’, 3-in. diameter flowers are white with a broad, bright purplish-red border
Tama No Hada – flowers are 4 to 5 inches in diameter and are white to pink with deep pink stripes; usually flowers in fall as well as spring
Wakaebisu – 2.5-in. diameter flowers are “double” (hose-in-hose) and are salmon pink with deep pink dots and blotches; this also flowers in fall as well as spring

As a boy in a small town in Georgia we had a St. Augustinegrass lawn. My dad started the lawn before I was born. That lawn was still doing fine when I left for college at age seventeen. I don’t remember weeds in the lawn during summer months. I do fondly remember winter “weeds” in that lawn.
To see clumps of winter annuals in our yard and in neighbors’ yards was a natural part of the transition from winter to spring. They added interest to what

would have been a plain palette of green. It was expected to see henbit with its square stiff stems holding up a display of small pinkish purple flowers in late winter and early spring. A clump of henbit was a great place to hide an Easter egg, especially a pink or purple one.
Wild geranium, another common winter annual, offered another good hiding place for Easter eggs with its pink to purple flowers. Large clumps of annual chickweed would nicely hide whole eggs. Green colored eggs would blend with chickweed’s green leaves.

Crimson clover with its reddish flowers, hop clover and black medic with their bright yellow flowers were good hiding places for Easter eggs. Plus clovers add nitrogen back to our soils.
I never remember my dad using any weed killer, he rarely watered. The lawn was healthy and thick enough to be a deterrent to summer weeds. But during fall and winter as the lawn would naturally thin and go dormant, winter annual weeds would run their course.
I’ve heard that the sense of smell provides our strongest memories. I remember the first mowing of the season with the clean smell of chlorophyll in the spring air. It was refreshing. Once mowed and as the heat took its toll, by late April or mid-May, these winter annual weeds were gone. What was left was a green lawn to help cool the landscape as the weather warmed. The lawn was mowed high as St. Augustine should be, played on and typically not worried with.
Most people have winter weeds in their lawns that let us know spring is near. Perhaps we worry too much with these seasonal, temporary plants that may have wrongly been labeled as weeds. Besides, how long have we been doing battle with these weeds and they are still here. Most lawns have countless numbers of winter annual seeds awaiting the cooler temperatures and shorter days of early winter to begin yet another generation. By May they are gone.
Plants with variegated foliage are very popular landscape selections. As flowers fade on other plants, the colors of variegated foliage continue to add interest through multiple seasons.
A very adaptable shrub that has been around for a long time, now has a selection with beautiful variegated foliage. Juliet™ cleyera offers green and white evergreen foliage that can brighten up a garden year around. New foliage adds additional interest with a maroon tinge.

Like other selections of Cleyera, Juliet™ needs to be matched to an appropriate spot to accommodate its mature size. Shrubs will reach about 8 feet in height with a spread of about 5 feet. Plants may look best when left to grow in a more natural form with light selective pruning. This shrub is probably not suited for planting in front of home windows but used as a specimen or as a nice screen plant.
Once established, cleyera is a low maintenance plant and is adapted to grow well without routine irrigation. My home landscape has very well drained soil and I have not needed to apply supplemental irrigation to two cleyera shrubs in over 20 years. Consider a spot that receives full sun or partial shade for your plants.
An added advantage of cleyera shrubs in general is that bees are attracted to the flowers so it makes an additional nectar source for pollinators in the spring.
Our trees and vines are flowering and lawns are starting to green up naturally, but one glance at the calendar and it is still early spring. The last official frost date for the Florida panhandle can be into April depending on location. We know our day time and night time temperatures are still fluctuating every other day. We also know the stores and nurseries are stocked with shelves and pallets of fertilizer. So the big question is when can I fertilizer my lawn?

My answer after years of practice is always it depends, but my non-scientific rule of thumb to homeowners is wait until you mow three weeks in a row and make sure you’re past the last frost dates for your area. If you need to mow three weeks in a row for height, then your lawn is actively growing and most likely we are into a temperature range good for fertilizer applications. If you apply fertilizer to a lawn that is dormant, the fertilizer will not be taken up by your roots and it can leach below the root zone wasting money while not improving the lawn and possibly causing environmental concerns.
With that said, there are some factors to consider. We always recommend doing a soil test first. This can be done in advance of spring. Your test results might indicate having sufficient nutrients in the soil, so not applying would save you money and the lawn would still look good. The soil test will also indicate what nutrients are in excess or lacking, then you can apply only the nutrients needed.
I have found that fertilizer is still very much misunderstood. When I ask homeowners whether they consider fertilizer to be medicine or a stressor, most will answer medicine and we all know if a little medicine is good, then a bit more is better. However, it is more accurate to think of fertilizer as a chemical stressor. If my lawn is unhealthy, then I force my lawn to grow and it can further weaken my plants. Think of it like this, if you’re not feeling well at night before you go to bed, should you consume one of those big energy drinks? Not if you want to sleep and hopefully feel better in the morning. Apply fertilizer when the lawn is ready and capable of having a positive response when spring fully arrives.

Here are some items you should know before you fertilize the lawn. Fertilizers used in Florida should have a license number that begins with F followed by a series of numbers. It is important to check your fertilizers before you apply. You need to know what type of turfgrass you have in your lawn. We have a lot of bahiagrass and centipedegrass lawns in the panhandle. Each will require a different regiment. You are only allowed to apply one pound of nitrogen per 1,000 square feet per application and you should never apply more than the recommended rate. I always refer to a childhood fable “The Tortoise and the Hare” when thinking about plant health. Slow and steady makes for a better lawn in the long run. This means you need to measure your lawn, understand how to calculate the nitrogen and then apply correctly with the right equipment and spreader patterns. We also recommend very little phosphorus (the middle number on the fertilizer bag 15-0-15) for Florida lawns. Our soils are usually sufficient and this is another item your soil test results will confirm.
Remember, your local Extension office is always here to help especially making sure you treat the lawn right. Think before you apply because your long-term goal is improving the lawn quality.

Flax lily is a popular perennial that adds interest to garden borders or when planted in mass. Plants can be affected by cold temperatures so a little maintenance as temperatures warm is often necessary. UF IFAS Escambia County Extension shares late winter care of flax lily In the Garden.

The plant has a crazy-sounding name, more like some little animal you’d find in Australia than a native plant. However, an ancient Florida plant it is, and a tough one at that. Growing close to the ground, it most resembles a large fern or a sago palm, if the sago had smooth, rounded leaf edges. Like the sago, the coontie (Zamia floridana) is a cycad—a group of palmlike plants that have been around so long that triceratops and stegasauruses ate them! Coonties are the only cycads native to North America, found in the states and island nations like Cuba and the Bahamas.

Another interesting feature of the coontie is its seed cones. These are large reddish orange cones that resemble magnolia seedpods. Both sexes of plant produce them in clusters ranging from one to five of the 2-7” long cones. Cones from the male produce pollen, while females produce seeds. If you are interested in attracting wildlife to your yard, the coontie provides good low-growing cover for birds and small mammals. It is also the preferred food for the caterpillar of the rare Atala butterfly. Members of the Timucuan and Calusa tribes ground up the starchy root of the coontie as a flour. However, the root contains a toxin and if it is not removed first, ingestion could result in severe abdominal pain and vomiting. From the late 1880’s through World War I, a large starch industry existed in Florida, producing flour from the coontie root.

At home in drier soil conditions like oak hammocks and pinelands in north central Florida, these plants can also adapt to a variety of soil pH types. Coonties are drought, cold, and salt tolerant, thus a great landscape choice for coastal landscapes near the Gulf or a bay. The plants are very long-lived and adaptable. In fact, the book Florida’s Best Native Landscape Plants notes it is “Very hardy and easy to care for. Will grow well in any part of Florida, even outside its normal range. An exceptional replacement for the closely related, often used, but non-native sago palm.” In other words, this is an ideal landscape plant that should be used more throughout Florida.
