Popular Tropical Plants for Zone 5
Zone 5, located in the northern United States and southern Canada, experiences cold winters with minimum temperatures ranging from -10°F to -20°F. Despite the chilly conditions, several tropical plants have adapted to thrive in this climate, adding a touch of the tropics to gardens in these regions.
These plants possess unique adaptations, such as cold tolerance, late blooming, and compact growth habits, that enable them to withstand the cooler temperatures. Let’s explore some of the most popular tropical plants that can bring a tropical flair to Zone 5 gardens:
Hardy Hibiscus
- Common name: Hardy Hibiscus
- Scientific name: Hibiscus moscheutos
Hardy hibiscus is a deciduous shrub that produces large, showy flowers in various colors, including pink, red, white, and purple. It blooms late in the summer, often extending its bloom time into the fall, providing a splash of color when many other plants are fading. Hardy hibiscus is relatively easy to grow and prefers moist, well-drained soil in full sun to partial shade.
Banana Trees
- Common name: Banana Trees
- Scientific name: Musa spp.
Banana trees are tropical plants that add an exotic touch to Zone 5 gardens. They produce large, banana-like fruits, although the fruits may not fully ripen in cooler climates. Banana trees prefer warm, sunny locations with well-drained soil. They can be grown in containers and overwintered indoors in areas with cold winters.
Canna Lily
- Common name: Canna Lily
- Scientific name: Canna spp.
Canna lilies are tropical plants with large, colorful leaves and showy flowers that bloom from mid to late summer. They are relatively easy to grow and prefer full sun to partial shade with moist, well-drained soil. Canna lilies can be grown in containers or directly in the ground and should be overwintered indoors in cold climates.
Growing and Caring for Tropical Plants in Zone 5
Growing tropical plants in Zone 5 presents unique challenges due to the cold climate. To ensure their survival, specific care requirements must be met, including proper soil preparation, watering, fertilization, protection from cold temperatures, and appropriate overwintering techniques.
Soil Preparation
Tropical plants prefer well-drained soil rich in organic matter. Amend the soil with compost or peat moss to improve drainage and provide essential nutrients. Ensure the soil pH is between 6.0 and 7.0, as most tropical plants thrive in slightly acidic conditions.
Watering
Water tropical plants regularly, especially during hot and dry periods. Allow the top inch of soil to dry out between waterings to prevent overwatering and root rot. Use lukewarm water to avoid shocking the plants.
Fertilization
Fertilize tropical plants monthly during the growing season with a balanced fertilizer. Avoid over-fertilizing, as this can lead to nutrient burn. Use a fertilizer specifically formulated for tropical plants or dilute a general-purpose fertilizer to half strength.
Protection from Cold Temperatures
Tropical plants are sensitive to cold temperatures. To protect them from frost and freezing, provide insulation by mulching around the base of the plants. Cover them with frost blankets or plastic sheeting when temperatures drop below 50°F (10°C).
Overwintering
In Zone 5, tropical plants cannot survive outdoors during winter. They must be overwintered indoors or in a sheltered microclimate. Bring them inside before the first frost and place them in a bright, warm location with indirect sunlight. Alternatively, create a sheltered microclimate by building a cold frame or using a greenhouse.

Incorporating tropical plants into Zone 5 landscapes adds a touch of exotic flair and creates visually appealing outdoor spaces. These plants can thrive in the region’s cold winters with proper care and thoughtful placement.
Size, Shape, and Color Considerations, Tropical plants zone 5
When choosing tropical plants for Zone 5, consider their size, shape, and color. Smaller varieties, such as dwarf bananas and bird of paradise, can be used as borders or accents. Larger plants, like hardy hibiscus and cannas, make excellent focal points or create dramatic backdrops. The varying shapes and textures of tropical foliage, from the bold leaves of elephant ears to the delicate fronds of maidenhair ferns, add depth and interest to any garden.
Companion Plants
Companion planting is a technique that enhances the growth and appearance of plants by placing them near others that complement their needs. For tropical plants in Zone 5, good companion plants include annuals like zinnias and marigolds, which attract pollinators and deter pests. Ornamental grasses, such as miscanthus and switchgrass, provide height and movement, while groundcovers like creeping Jenny and vinca help suppress weeds and retain moisture.
Focal Points, Borders, and Accents
Tropical plants can serve various functions in Zone 5 gardens. Large, showy specimens like banana trees and tree ferns make stunning focal points that draw the eye. Smaller plants, such as coleus and begonias, can create colorful borders that define garden beds and walkways. As accents, tropical plants can add a touch of the unexpected to traditional landscapes, providing a burst of color or texture among more common perennials and shrubs.
