Hot and dry: That’s the lament of gardeners in most regions in high summer, and also of many plants in their flower gardens. The author of a new book called “The Ultimate Flower Gardener’s Guide” is here to suggest which perennials can stand up best to the test, plus give us some lavender-growing advice – speaking of plants adapted to hot and dry.  



Also on the agenda: a tip on a bulb you may not have grown before but could order to plant this fall, surprise lilies.
