Spiny Black Olive Terminalia molinetii Spiny Black Olive
The Spiny Black Olive is a lesser known native of South Florida documented in the wild of Lee and Miami-Dade Counties. Other than some historical documentation of wild specimens, there is very little information on its landscape uses.
As its name suggests, the Spiny Black Olive is covered in spines. This makes it a suitable nesting and foraging tree for local bird populations who will find plenty of food and safety in its many thorny branches.
It’s high salt tolerance makes it a beautiful specimen for coastal settings and adapts easily to container gardens. You will more often see the Spiny Black Olive planted as a bonsai because of its naturally geometric branching.
We hope to provide more information on this one in the future as it works its way into our landscapes. A lot of unique potential for this one though!
Availability: Rarely available in retail nurseries
Landscape Use
We hope to see the Spiny Black Olive used in the landscape more, but we anticipate it would make an amazing specimen planting. Its naturally geometric shape will work well in formal and informal settings, but will likely look best as a single planting or in isolated groups of no more than three.
It would make an excellent addition to those seeking to invite nesting and foraging birds to the landscape. Just don’t forget to add larval host plants nearby to be sure baby birds have plenty to eat in the safety of this tree.
Most cultivated documentation of the Spiny Black Olive has it grown as a bonsai. Its wide range of soil conditions and unique branching form make it an optimal specimen almost immediately.
Establishment and Care
We do not have a lot of information on its establishment and care. We hope to provide more information on this. We can speculate it is relatively easy to establish due to its wide range of soil conditions, hardiness in coastal settings, and slow growth habit.

Guaiacum sanctum Lignum Vitae, Lignum-vitae Shop Here
The lignum vitae boasts one of the most striking and intricate purple flowers among any other small to medium sized native trees. Blooming heaviest in spring, a well established and healthy tree will provide hundreds of purple flowers that fade and slowly transform into a small, gnarled orange seed.
Lignum vitae is very slow growing as little as one inch per year, and creates a very dense, hard wood. This made it suitable for many human uses most notably prop shafts on boats and bowling pins. Unfortunately, harvesting this specimen almost wiped them out entirely except for a small population that is now protected on Lignum Vitae Key State Park, only accessible by boat and appointment.
Add this one to your landscape to not only make a statement specimen piece, but also as a historical addition.
Soil: Somewhat moist to very long dry periods. Humus and limerock soils.
Size: 8-15 feet tall and wide
Flower: Purple, warmer months but mostly in spring
Fruit: Orange
Salt tolerance: Tolerant of occasional saltwater inundation, moderate tolerance for salt spray.
Landscape form: Small tree, specimen planting
Phenology: evergreen, long lived tree
Wildlife Factor: Local birds eat the seeds, attracts many pollinators, larval host plant for lyside sulphurs.
Ecotype: Rockland hammocks
Landscape Use
Use Lignum Vitae where it is sure to garner the eyes of onlookers. You do not want this one hidden in the back of a property or side yard, it should be front and center.
Due to its slow growth habit, accompanied by a higher price tag, the lignum vitae should be well considered before planting. Some specimens will only grow up to an inch in their first few years. Full sun and well drained soils will help it to thrive.
This specimen tree should hold flexibility in its intended look and may not be suitable for formal landscapes requiring an obedient and uniform tree. The branching can be irregular and overtime, the trunk may lean a bit rather than perpendicular to the ground. But this gives it character and another good reason for onlookers to gaze upon it in awe.
Establishment and Care
In the right location, the lignum vitae will be an easy and low maintenance specimen tree. For establishment, be sure the site is well drained and accompanied by companion plants with the same watering needs.
The lignum vitae will need routing water the first three to six months before it can thrive on its own. It is more forgiving of a missed watering than most other plants.
Sometimes, yellowing in the leaves can occur, a signal that the lignum vitae needs some fertilizer.
Satinleaf is a beautiful, medium sized South Florida tree graced by its interesting, two-tone foliage. The glossy green top side of the leaf contrasts nicely with the silky brown underside.
The slower growth habit of the Satinleaf makes its branching and trunk structure very strong, giving it a high wind resistance, great for windy locations and durable in hurricanes.
The flowers of the Satinleaf are fragrant and virtually year round, slowing in the colder months. The flowers then give rise to berries eaten by local wildlife.
Be careful, the Satinleaf is cold sensitive. Freezing temperatures can kill the above ground growth, but will typically resprout from the root.
Soil: Usually moist soils to very long dry periods . Adaptable to a wide range of soil pH but prefers slightly acidic soils.
Size: 20-40 feet tall, and 10-25 feet wide
Flower: White, year round, fragrant blooms
Fruit: Purple, black
Salt tolerance: Not tolerant of salt inundation, low tolerance of salt spray.
Landscape form: medium sized tree, loose growth habit
Phenology: evergreen, long lived tree
Wildlife Factor: birds and wildlife feed on the fruit, pollinated by insects
Ecotype: Tropical rockland hammocks
Landscape Use
The Satinleaf makes a great loose growing and upright tree that can grace the corner of a home or building. It will not provide much screening or view obstruction making it a great fit for placement around showy architecture or outdoor structures.
Its high wind resistance also makes it a suitable option near structures where safety and risk is of higher concern. But it is slow growing, so make sure you have plenty of time to enjoy the growth of the tree or select a larger specimen to start out with.
Place the Satinleaf near walkways or social areas, as the fragrant blooms will provide subtle and enjoyable floral aromas without becoming overwhelming.
Establishment and Care
The Satinleaf can be tough to establish at times, although seedlings propagate and establish quite effortlessly. Be sure the soil is not perpetually wet, but that it receives enough water during establishment to develop a large, drought tolerant root system.
Water regularly the first month, and monitor leaf color each month there after. Yellow, droopy leaves can be a sign of too much water, especially when on the older growth. Crinkly, dry leaves can be a sign of not enough water, especially when on the new growth.

Flaveria linearis Yellowtop, Narrowleaf Yellowtops, Yellowtop Flower Shop Here
The beautiful mounding growth habit of this wonderful Florida wildflower will have you wanting more. Yellowtop is native to all coastal counties of central and southern Florida where it can tolerate significant salt spray and brief inundation from brackish waters.
This often overlooked wildflower puts on a great show in fall and winter when it bursts out of its grass-like state with hundreds of yellow flowers that attract a wide and diverse range of butterflies, moths, and bees.
You will enjoy these clouds of yellow flowers gracing your garden.
Soil: Somewhat moist soils to somewhat dry soils. Adaptable to a wide range of soil pH.
Size: 1 foot tall by 2 feet wide
Flower: Yellow in fall
Fruit: NA
Salt tolerance: Very high salt spray tolerance, and tolerant of brief water inundation
Landscape form: Perennial wildflower, low-growing
Phenology: Evergreen, 2-3 year lifespan
Wildlife Factor: Incredible nectar source
Ecotype: Depression and basin marshes, wet prairies, pine rocklands, edges of mangroves, disturbed areas.
Landscape Use
This underutilized wildflower can grace most any garden setting. Use in a more forward setting where it can be allowed to grow snuggly among other plant species. Grouped with other wildflowers to provide fall color, or work in with greenery where it will stand out when in bloom.
Yellowtops’ very fine texture, especially when in bloom, allows it to work well with medium to coarse textured plants and material, especially limestone and shell. But it’s fine texture also compliments other fine textures like grasses and saltbush.
Plant in areas of full sun with moderate soil moisture. Cut back after blooming to promote regrowth for next year. The yellowtop often begins to look its best after year one.
Establishment and Care
Yellowtop is a very hardy wildflower when in the right location. Establishment from a one gallon container usually takes about 1-2 months where it can then receive weekly watering. If there area is too dry though, the yellowtop may survive but not thrive.
Cut back after flowering in late fall or winter to promote new growth for next year.
It will reseed in the yard, but not considered aggressively.
Salvia coccinea Tropical sage, scarlet sage, salvia Shop Here
Whether you’re looking to introduce your first wildflower to your landscape, or searching for a colorful spike to introduce to an existing garden, Tropical Sage is sure to make an impact.
Blooming nearly year round and tolerant of heavy pruning to push new growth quickly, tropical sage provides color and texture to the garden that provides interest in every season in South Florida hardiness zones.
This one is available in red, pink, or white flowers borne on a flower spike that extends above the foliage. Flower spikes can be up to a foot long!
Gardener beware, as with most Florida wildflowers, tropical sage easily reseeds in the landscape which should be considered when planting. This does ensure an endless supply of fresh new plants, though!
Soil: Well drained, preferring somewhat moist but no flooding to dry soil. Adaptable to a wide range of soil pH.
Size: Can reach 6 feet if left untouched, looks its best maintained at 2-3 feet, and is narrow at about 1 foot wide.
Flower: Red, pink, white spike, year round in warmer winters.
Fruit: Brown
Salt tolerance: Moderately salt spray tolerant, not tolerant of inundation.
Landscape form: Medium sized wildflower
Phenology: Annual or short-lived perennial. Self seeds.
Wildlife Factor: Attracts migrating hummingbirds. Attracts butterflies, bees and other pollinators. Small birds such as warblers and nut-hatches enjoy the seeds.
Ecotype: Dry and distrubed sites, shell mounds, calcareous bluffs
Landscape Use
The tropical sage makes a great addition to both native and non-native landscapes. Its continuous colorful blooms allows it to mix well in both settings, and its new growth, a vibrant green, fits well even in a more exotic plant palette.
Tropical sage can be planted as a stand alone specimen to introduce a flower spike to an area of greenery. Add it to a pot at an entry or around the pool accompanied by low growing and weeping material to create a dramatic effect that is sure to “wow!”
When planted in masses, arch around a focal point or mix in with native grasses. When looking for a cottage style or wildflower garden, mix the three colors together to capture as much diversity as possible.
Because it can tolerate partial shade settings, the Tropical Sage is the perfect wildflower to bring color to areas that may be more difficult to do so. Great for pollinator gardens, butterfly gardens, formal and contemporary gardens, container gardens, and partial shade settings.
Establishment and Care
This one can be on the moderate to high range of maintenance requirements, needing more of a “gardener’s touch.” Tropical sage benefits from one-third to two-thirds cut backs three to four times per year. This will keep them attractive and from developing a leggy appearance.
Prune away expired flowers as frequently as you wish to keep blooms going and reduce reseeding in the landscape, or leave the seed heads to invite the small birds that will feed on the seeds.
Establishment with this one is relatively quick. Usually after 2-3 months, the Tropical Sage can thrive on its own, except for in severe droughts. Water as needed when leaves are noticeably wilted in the mornings or crispy in the afternoons.
There are no major pests or diseases to worry about with this one.
