Lantana plants are native to the tropics, which is why they bloom in humid and hot areas. They thrive in well-draining, moist soil, but can manage in drought conditions too. They prefer the afternoon sun and bloom all year long as small clusters of white, pink, yellow, orange, and red. They tend to attract plenty of hummingbirds, butterflies, and bees.

2. Lemon Verbena

The Lemon Verbena comes from South America and is a hardy heat-tolerant plant that is grown around the world. The plant is perfect to station near your windows and doors since you will be able to take in the sweet citrus aroma too.
