Recently, basil has been getting a mildew that turns it yellow/brown, then kills it ("Downy Mildew"). The trick is to grow it as big as you can and then eat it before it's dead. So some of the basil leaves are a little yellow/brown, but the majority of it is perfectly fine. If it smells like basil, it's good!
The sweet potato tendrils are an up and coming super food. During a recent web search, i learned that "Apart from being tasty, this simple vegetable is packed with nutrition, being the only vegetable with Iodine, a common substance found in seafood. It also contains vitamin A, C and Calcium; In the Philippines, it is widely believed that lactating mothers fed sweet potato tops improve their breast milk production. In fact, it is now a major ingredient of a commercially available food supplement drink in the Philippines. It is also a folk remedy which is used to treat diarrhea and dizziness". Enjoy!
