Big Smile is an outstanding daylily! The color is gorgeous, the flower is huge and the plant habit is stellar! It blooms almost continuously and multiplies quickly.

Okay it did not start well but I am giving it a chance. Beautiful plant but too tender for my area unless started clump style not one bareroot. Three small bareroot attempts died in the past three years and finally I got one half of a plant to survive in a very sheltered area. It is doing quite well, blooms, and I even divided a piece off for a trade and it survived the winter. When it gets bigger will see if it will grow in not so sheltered a spot. Beautiful Edgings on the otherhand looks similar and does wonderfully in the wooden raised beds..

What a gorgeous daylily this is! Stunning big flowers with such delicate pastel coloring. This is only the second year I have the plant and it's getting several blooms a day on it. Even the first bloom had a perfect shape and lovely coloring. Highly recommended.

Bought "Big Smile" thru the Internet, and the plant sent was quite small. It didn't bloom at all this past summer, but I'm hoping for better things next season.

Just acquired 2 fans summer 2003. Bloomed once. Now October, have had temperatures in 40s at night. Just discovered another bloom scape. Now in 3rd summer (2005), this lily has not stopped making bloom scapes 2-3 at a time continuously. Great multiplier, clump has more than tripled in size.

I purchased this daylily from Parks Seeds last year and this year I have two stalks of flower buds on it. They are a beautiful flower and I look forward to it getting bigger and giving off more flowers as the years go by.
