The tallest Kniphofia we offer, 'Lady Luck' lends itself well to create dramatic height in a limited footprint. A mid to late season bloomer, this plant produces chartreuse buds that open to white flowers over top of a very large clump of foliage. It's jam-packed with flower spikes, so you know you'll enjoy a prolonged display in summer.Tested for hardiness in our Michigan zone 6, heavy snowfall winters, and could be hardier with winter mulch and protection.
