HUDSON VALLEY was new to my garden last summer. It is an old-fashioned yellow: short, poor branching, thin substance and lower bud count but redeemed by large blooms, pure glowing color and simple prettiness. I planted it due to its promise of fragrance and I was not disappointed. It probably had the strongest fragrance of any daylily I have smelled to date--pure, sweet lily of the valley mixed with honeysuckle.
While I might not ever use it in hybridizing, I would keep a clump of it around just to enjoy the fragrance on a warm summer evening.
