(Summer Jewel Red Tropical Sage) Butterflies, hummingbirds and honeybees enjoy this Fleuroselect Gold Medal winner, which is an outstanding choice for bright red color from June to autumn. This type of Tropical Sage is generally the first to flower for us.
Summer Jewel is easy to grow and a great addition to annual flower beds or containers. It prefers rich, well-drained soil and regular watering. Plant it in full sun or partial shade as a tender perennial in mild climates and as an annual elsewhere. Reaching up to 36 inches tall and 24 inches wide, this sage is an ideal border plant. Use it where you want to create intense color and attract pollinators.
One of our Top 10 Hummingbird Plants, this sage belongs in all gardens regardless of zone. We consider it indispensable due to its long bloom, low maintenance and spectacular show.

Learn more about how we analyze plant colors
We based our analysis of this plant’s floral and foliar color on the internationally standardized color system published by the U.K.’s Royal Horticultural Society. Called the RHS Large Colour Charts, this publication is a boxed set of color swatches arranged in fans and containing all the colors that RHS has identified in horticulture. RHS gives each color a common name and code number.
Each swatch has a small hole punched into it. We place the swatch over a flower petal and compare the blossom’s color to that of the card. When using RHS colors to compare plants that you want to combine in a flowerbed, in bouquets or in some other manner, RHS says to view them indoors in north light. If you are matching our digital swatches to flowers already in your garden, pluck two or three fully open blossoms of each plant that requires analysis.
You may find that the plant you receive from FBTS varies somewhat in color from what appears in our color analysis or our photograph due to a number of factors, including:
- Variations in photographic colors based on lighting level at different times of day
- Differences in the resolution of digital screens
- Seasonal changes in plant color due to changes in temperature and plant cycle and
- pH or soil chemistry that varies from one locale to another and causes color shifts.
Finally, RHS notes that you shouldn’t attempt color matching when your eyes are fatigued.

Exposure


This plant needs or tolerates more than six hours of intense sunlight daily. Many Salvias only thrive in wide-open locations where they receive long hours of full sun. However, full-sun species sometimes tolerate a bit of partial shade. Or a Salvia that loves partial shade may be amenable to spending part of its time in full sun.
In general, this sun/shade adaptability shows up in Salvias that do best in cooler climates when grown in full sun and thrive in hot climates when partial shade is available. So full-sun Salvias sometimes are also categorized as partial-shade plants and vice versa.


This plant grows well in partial shade, such as the kind on the edge of woodlands or under deciduous trees with breaks in the foliage through which dappled sunlight penetrates. Many Salvias thrive in partial shade, including ones that spend part of their day in full sunlight. Some species need partial shade to overcome severe heat and dry soil.
Garden Uses


In cold climates, this Salvia is a good choice to use as a summer blooming annual.
Plant it in your garden well after the threat of last frost in your area.
Capable of quick growth and floriferous long-lasting bloom, tender perennial Salvias are a don't-miss addition to an annual flowerbed. Although perennial in the warmer climates of their native lands, tender or half-hardy perennials are planted as annuals in locations where frosts and freezes are likely to occur in fall, winter and spring.


This plant grows well in an outdoor container, such as on a patio.
Some containerized Salvias leaf out and flower year after year following a period of dormancy. Annuals in containers may die back and appear to grow again when they reseed.
During extreme heat, check the soil in container plantings once or twice daily to be sure it doesn't completely dry out. Feel its surface for coolness, then gently poke a finger into the soil to check for dryness.
Growing Habit


Plant hardiness Zones defined by the U.S. Department of Agriculture tell you the minimum temperatures a plant can withstand in your garden. The USDA divides the nation into winter climate areas from coldest (Zone 1) to warmest (Zone 11).
However, it is sometimes possible to grow a Zone 6 Salvia as a perennial in Zone 5 if you provide preferential care, such as winter mulching and a location sheltered from harsh winds. In contrast, a Zone 9 Salvia may act like a perennial in Zone 10 if given a bit of shade or extra water.


To create a harmonious landscape plan, it is important to consider the heights of individual plants.
Height also affects function. Short Salvias often make excellent ground covers that conserve soil moisture and discourage weeds while also brightening your yard. Medium-height Salvias, such as ones 36 inches tall, often are ideal border plants. A tall Salvia planted singly can highlight a landscape; multiple plantings can form an attractive screen.


By considering the width of a plant, you can determine how many to place in a row or what other plants to grow with it.
For example, a narrow, moderate-height Salvia may look good interplanted with bushier species, kind of like Mutt and Jeff.
In contrast, wide-spreading Salvias are economical for hiding lengths of wall and fence or for creating hedge-like divisions in a yard.
Water Needs


This plant needs regular watering based on what is appropriate to your local conditions.
In some extremely hot, arid climates, this may mean daily watering in Summer. Although many drought-resistant Salvias survive on little to no watering due to local rainfall and deep roots meeting their moisture needs, others need regular doses. The size and frequency of the dose depends on your climate.
Blooming Season


This plant reaches peak bloom in Fall or flowers for much of the season.
It may begin flowering much earlier in the year. Bloom time for some Salvias lasts from Spring till first frost. Others begin flowering in Summer and continue into Fall. There are also Salvias that don’t bloom until late Fall and continue into Winter if grown in mild-Winter areas.
There is a great deal of overlap in blooming seasons for Salvias.


This plant reaches peak bloom during Spring or flowers for much of the season.
However, it may begin flowering sooner. Some Spring-blooming Salvias begin flowering in Winter; others start in Spring, keep producing color through summer and may continue on into autumn and first frost. Still others flower only in Spring.
There is a great deal of overlap in blooming seasons for Salvias.
Wildlife


Honeybees love this plant’s nectar. As a honeybee burrows down into a Salvia’s nectar-rich flowers to reach dinner, it accidentally gathers pollen and drops it on the stigma of that blossom or of ones on other nearby Salvias. Fertilization results in seed production.
By growing honeybee favorites, you attract these helpful pollinators to all your flowering plants and increase productivity


This plant attracts butterflies whether for nectar or as a host for their caterpillars. Some butterflies feed on a limited range of flowering plants and only lay eggs on one kind of host plant. Salvia nectar lures adult butterflies. Placing host plants, such as Milkweeds (Asclepias spp.), next to nectar plants builds butterfly habitat. In exchange, the butterflies improve fertility in your garden through pollination.


Based on our experience and reports from customers, hummingbirds (Trochilidae spp.) love this plant.
Hummingbirds exist only in the Americas where their 300-plus species are particularly fond of the nectar in brightly colored Salvias from the Western Hemisphere. However, if favorites aren’t available, they dine on the nectar of most Salvias.
Hummingbirds repay thoughtful plantings by helping to pollinate your garden

Synopsis:
Although it probably originated somewhere in Mexico, Tropical Sage (Salvia coccinea) existed in the American Southeast prior to European exploration of the New World, so it is considered an American native. It's also native to Central and South America and has naturalized in parts of Europe and Africa. Medical researchers think its phytochemicals may fight illnesses caused by inflammation and oxidative stress from free radicals.

Salvias that grow well in Florida may behave differently from one region of the state to another. This may mystify gardeners who have just moved to Florida or have moved to a different area in the state. Based primarily on seasonal variations in temperature, the four main regions are North, Central, South and Tropical Florida.

Synopsis:
Warm colors tend to take center stage in a landscape as well as brightening the shade. Yet warm colors generally aren't associated with shady sage (Salvia) gardens, because there are far more shade-tolerant sages in the blue to purple range. So we decided to poke around our catalog and pull together some hot choices that thrive in partial shade.
To make landscaping even easier, you may want to limit your choice of plants to one color. Massing is dramatic.
