Gardeners' Notes:

Positive firecracker On Jun 10, 2012, firecracker from Montrose, PA (Zone 4b) wrote:

Clumps rapidly. I've divided and moved it and it just keeps on blooming here in Zone 4 of the north PA hills.

Positive MollyJane On Apr 16, 2010, MollyJane from Ravenna, OH wrote:

The best gold daylily. Long blooming season. No fancy markings, just a giant clump of color which is visible from a great distance. Clumps increase rapidly.

Out of my 30 different daylilies, THIS one is my favorite! SO SHOWY......It's the focal point of my whole front yard. If I could find another performer like this one in another beautiful color, I'd buy it in a minute. Plant is COVERED w/flowers every day and it blooms for such a long time.

This is a great, reliable plant in my zone 5 garden. Grows into huge clumps, with large flowers that are a nice light golden yellow, with good substance. They have a nice long bloom season.

Love Mary Todd. The substance, shape and size and foliage habit is stunning. Get alot of comments from garden visitors on this one. A stately beauty with prolific bloom over a long period. Couldn't be without it.

Good color & substance, very tolerant of wet weather, and flowers fade gracefully. A real winner.

Positive TBGDN On Feb 22, 2006, TBGDN from (Zone 5a) wrote:

Nice big golden yellow flowers on tall stems. Hardy here and grows well.

Once this plant reaches clump strength, there's no stopping it. Though not listed as a rebloomer (to my knowledge) it is one of the first to bloom in my zone 4 garden and just keeps going until late in the season. What a pleasant surprise and pretty bright yellow color.
