Wow love those dark Iris. All my Iris are pastels.
Eat the dandelions! Very nutritious. Young leaves are best in a salad, but the entire plant is edible. We even tried dandelion root "coffee" this evening. Kinda roasted nutty flavor but we did not like the after taste.
Your Solomon's Seal will produce dangling "berries" later on. It's called Solomon's Seal due to the markings on the tubers.
