Easiest Plants to Care for During St. Louis High Heat Temps

In St. Louis, the summer months can bring hot and humid weather, which can be challenging for many plants and flowers. However, there are some hardy and drought-tolerant options that are relatively easy to care for during high heat conditions. Here are some suggestions:

1. Succulents and Cacti: These plants are excellent choices for hot weather since they have adapted to arid conditions. They store water in their leaves and stems, making them highly drought-resistant. They thrive in sunny spots and require minimal watering.
2. Zinnias: Zinnias are resilient annual flowers that come in various vibrant colors. They are tolerant of heat and can withstand dry conditions. Regular watering and deadheading spent blooms will keep them blooming all summer.
3. Lantana: Lantana is a heat-loving perennial with clusters of colorful flowers. It is drought-tolerant and attracts butterflies and hummingbirds. Plant it in well-draining soil and give it some sun, and it’ll thrive with minimal care.
4. Portulaca (Moss Rose): Portulaca is a low-growing, colorful annual plant that thrives in hot, dry conditions. It requires full sun and infrequent watering.
5. Black-eyed Susan (Rudbeckia): Black-eyed Susans are hardy perennials with bright yellow flowers and a long blooming season. They can tolerate heat and drought once established.
6. Blanket Flower (Gaillardia): Another hardy perennial, the blanket flower, is known for its vibrant red and yellow flowers. It can handle the heat and doesn’t require much water once it’s established.
7. Agastache (Hyssop): Agastache is a tough perennial with fragrant spikes of flowers. It is drought-tolerant and attracts pollinators like bees and butterflies.
8. Marigolds: Marigolds are easy-to-grow annuals that can handle hot summers and are relatively low maintenance. They come in various colors and can add a pop of brightness to your garden.
9. Russian Sage (Perovskia): Russian sage is a drought-tolerant perennial with silvery-gray foliage and tall spikes of lavender-blue flowers. It’s a beautiful addition to any garden and can handle the heat.

Remember to provide adequate water to newly planted flowers until they establish their root systems. Once these plants are established, be cautious not to overwater them, as they generally prefer drier conditions. Mulching around the plants can also help retain soil moisture and keep the roots cooler during the hot summer months.
