Madalene Hill Rosemary is sometimes erroneously labeled Hill Hardy Rosemary. There is no separate plant named Hill Hardy Rosemary.

As with all Mediterranean plants it is important for the soil to drain well. If the land holds puddles, this is an inappropriate spot for your Rosemary. In humid climates, raised planters may help with air circulation.
