You might want to consider a Crape Myrtle (Lagerstroemia indica). They're fantastic for sunny and warm climates, providing stunning pink blooms throughout the summer. Plus, they're relatively easy to care for once established. Just ensure they have good drainage and give them a light prune in late winter to encourage new growth. Another great option is the Rose of Sharon (Hibiscus syriacus), which also loves the sun and brings a tropical vibe with its vibrant flowers. Both would make lovely additions with their long blooming seasons!
