Q.How Much Heat Can A Mountain Laurel Take?
W’ere 9B but very hot- 90’s – 100’s in the summer. I wish zones took heat into account. What other shrubs or perennials can take the heat? We have sycamores, palms, camelias, holly, boxwood and other non-inspiring plants. Roses thrive.

If a zone range for a plant does not include your zone 9, that means it may not be able to thrive in your warm weather. Here are plants that can take the heat:
