Lantana flowers are perennial shrubs valued for their numerous blossoms and ease of cultivation. The plants bloom during summer, producing attractive flowers in shades of red, yellow, orange, pink, white or violet, depending on the variety. The flowers form in clusters and change colors as they age, resulting in some plants with several different colored flowers. The blooms also emit a strong fragrance, which is often considered overpowering and unpleasant. Native to the Caribbean, lantana flowers require consistently warm temperatures to thrive, making them ideal container plants in most temperate regions.
Plant lantana flowers in a container filled with well-drained potting soil. Keep the plant outdoors in a location that receives full sunlight throughout the day. Bring the plant indoors anytime temperatures drop below 30 degrees F and place in a well-lit window.
Water once every 7 to 10 days or whenever the top inch of soil is dry to the touch. Soak the soil thoroughly at each application to ensure the plant absorbs plenty of moisture. Apply water directly to the soil instead of watering overhead, as wet leaves are more susceptible to fungal diseases and pests.
Feed lantana flowers once per month during spring, summer and fall using a balanced 10-10-10 NPK fertilizer. Water lightly before and after fertilizing to prevent root burn and to release the nutrients into the soil. Apply the fertilizer at the rate recommended by the manufacturer for the best results.
Remove faded and dead lantana flowers whenever possible to prolong the blooming season and encourage the formation of new blossoms. Pinch off the old flowers near their point of origin to reduce damage and disease vulnerability.
Prune once per year during early spring to keep the plant compact and bushy. Use hedge clippers to remove overgrown, bare, diseased and damaged limbs to increase the overall health and visual appeal of the plant.
