March is a good time to shop for and add lungwort (Pulmonaria) and Lenten rose (Helleborus) to your garden. Lungwort is an early flowering shade perennial that often struggles in the heat and humidity of our Tennessee climate, so be aware that Pulmonaria longifolia cultivars and hybrids are much more durable. Good selections are ‘Roy Davidson,’ ‘E.B. Anderson,’ ‘Trevi Fountain’ and for its vigor and heat tolerance, ‘Diana Claire.’
