1. Pentas (Pentas lanceolata)
Pentas lanceolata is a heat-loving, ever-blooming tropical perennial that is one of the very best plants for attracting butterflies and hummingbirds. In USDA zones 10–11 it grows as a woody shrub reaching 3–4 ft (sometimes up to 6 ft in ideal conditions), while in cooler climates it is treated as an annual or container plant or seasonal bedding plant, typically staying 18–30 inches tall and wide.
Key Features
- Flowers: Dense, rounded 3–4″ clusters of small, star-shaped blooms (hence the name “starcluster”). Colors include white, pink, rose, red, magenta, lavender, and bicolor varieties.
- Bloom time: Nearly year-round in frost-free climates; late spring until first frost elsewhere. Deadheading is rarely needed — it just keeps pumping out flowers in the heat.
- Foliage: Bright to medium green, lance-shaped leaves with a slightly hairy texture.
- Growth habit: Upright, mounded, and well-branched; modern hybrids (Graffiti®, Butterfly, Lucky Star®, Starla®, Sunstar® series) are very compact and floriferous.
2. Tropical Hibiscus (Hibiscus rosa-sinensis)
The Tropical Hibiscus, with its large, showy blooms, is a Florida favorite. These flowers come in a vast array of colors, from fiery reds and oranges to soft pinks and yellows. They thrive in the Florida heat and humidity, making them an excellent choice for summer gardens. They are also relatively easy to care for, making them suitable for gardeners of all levels. Understanding the specific needs of the Tropical Hibiscus will ensure vibrant blooms throughout the summer. These flowers need a good amount of sunlight to bloom, at least six hours per day. They also need well-draining soil and regular watering, especially during dry spells. These plants can tolerate Florida’s heat and humidity, but they are not very frost tolerant.
Care Tips for Tropical Hibiscus
- Sunlight Needs: Plant Hibiscus in a location that receives at least six hours of direct sunlight each day. This exposure is critical for abundant flowering. Insufficient sunlight will result in fewer blooms and a less vigorous plant.
- Watering Schedule: Water regularly, particularly during hot and dry periods. The soil should be consistently moist, but not waterlogged. Overwatering can lead to root rot, which can seriously damage the plant.
- Fertilizing Practices: Feed your Hibiscus with a balanced fertilizer during the growing season (spring and summer). This will encourage healthy growth and vibrant blooms. Follow the fertilizer’s instructions carefully to avoid over-fertilizing.
Regular pruning encourages new growth and keeps the plant compact and tidy. Prune after the flowering season ends. This helps maintain the desired shape and size. Deadheading, or removing spent flowers, encourages new blooms. If your plant experiences pests or diseases, act fast to prevent them from spreading. Some common problems include aphids, whiteflies, and fungal diseases. Regular inspection and prompt treatment are critical. For example, aphids can be washed off with a strong stream of water or treated with insecticidal soap. Fungal diseases can be prevented by providing good air circulation and avoiding overhead watering. By following these care tips, you can enjoy the beautiful blooms of your Tropical Hibiscus all summer long.
3. Impatiens (Impatiens walleriana)
Impatiens are classic flowers that provide a burst of color in shady areas. They are available in a variety of shades, including pink, red, white, and purple.

This can reduce the risk of these issues. Choosing Impatiens that are resistant to common diseases is an option. Impatiens are perfect for adding beauty to shaded areas. Their bright colors and easy care make them a must-have for summer gardens.
Key Considerations for Impatiens
- Light Requirements: Impatiens flourish in shady spots or areas that receive morning sun and afternoon shade. Direct, intense sunlight can scorch their delicate leaves. This preference makes them ideal for planting under trees or in areas with limited sun exposure.
