Like many gardening enthusiasts, I’ve struggled with keeping my garden vibrant during scorching summer days.
But after years of trial and error, I’ve discovered some amazing perennials that don’t just survive but actually thrive in the heat.
Today, I’m excited to share my favorite sun-loving champions that will turn your garden into a colorful oasis.
Top 15 Heat-Loving Perennials
1. Pentas (Pentus lencia Lada)
Every time I see these star-shaped blooms in my garden, they remind me of a miniature galaxy. Their clusters come in the most cheerful colors – red, white, pink, and lavender.
