Sedum mexicanum ‘Lemon Coral’ This is one dazzling workhorse of an annual – although it is a perennial for those of you in Zone 7 or warmer. The screaming yellow foliage never stops drawing attention. It is a terrific filler or spiller for containers, although I use it more as a weed-smothering mat around perennials and flowering shrubs. ‘Lemon Coral’ thrives in full sun, heat and dry conditions. Plus it’s deer resistant. There was a large display container of ‘Lemon Coral’ in a booth I was staffing at The Maine Flower Show. ‘Lemon Coral’ was probably the most popular plant that people asked me about and wanted to ‘pet’!
