One of the best daylilies ever, Big Time Happy deserves to be better known. Often available in big box stores the potted plants are strong growers and early bloomers. Big blossoms are yellow with a hint of green and very fragrant.
Plant responds really well to foliar fertilizer, my container plant bloomed for months.
Trouble free and beautiful, BTH is a great addition to the garden - I love this plant!

Starts fairly early and blooms all summer with a couple of short rests. It has proved to be drought tolerant and consistent. I have it in part shade. If you love yellow daylilies, I recommend this one!
