Coral Bells (Heuchera) 'Pistache' glows like neon in the garden. I have two that sit in the 'Love and Marriage' sector of my backyard. I usually plant in odd numbers but decided to enhance that area with a union of two. They are small in size but huge in impact. You can see them glowing from way across the garden. In the fall, they turn russet and orange. They are quite the pair!
