With their white edging, the dark purple - almost black flowers of Nemophila 'Penny Black' display an elegant look. Gardeners who grow flowers just because they are black may want to include this easy yet handsome annual in a black flower garden. The deep lobed leaves have a delicate fern-like appearance.
Nemophilas thrive in our cool maritime climate; plants will die if the weather is too hot and humid. The plants adapt well to containers and hanging baskets, where they flower all summer long. Nemophilas thrive best when soil doesn't dry out.
