I got a surprise for first year bloom was awesome. It bloomed a good part of the summer. Lovely tall daylily. Hardy too.

Indeed a stunner in the summer sun. It truly does
seem to glow in the daylight!

A healthy, durable and strong cultivar. Can't be beat
for strong root systems. A two year old plant in a pot
in the ground not only burst through the plastic pot, but
the clump was virtually indestructile. Tough cookie,
beautiful flower!

While my clump seems a little short, its vigor and good looks are extrordinary.

What an eye-catching, attractive daylily. Height, vivid coloring, multiple blooms. Everyone asks about this one.

Luminiscent tangerine - what a stand out in the garden - super hardy, repeat bloomer, holds up well to very cold winters followed by very hot summers here in NE. Very tall, grows to almost four feet. Stunning in the back of the border.
