If I could only have one daylily, this would be it!

One of my first daylilies and still my favorite. The color is bright but not brazen. The smell from a large patch of these is so wonderful. Not something you find often in the newer cultivars.

What a classy older daylily! Still one of my favorites.

I enjoy this oldie and it is hardy here.

Positive Ishtar64 On Jun 20, 2006, Ishtar64 from Cedartown, GA wrote:

Tough as nails, Hyperion can live through droughts, rains and neglect. The flowers are a bright, light yellow, the foliage is fairly dark. The scent is pleasant. This one's highly recommended!

This is a classic daylily. Nice fragrance, but I have to stick my nose in the flower in order to enjoy.

Classic 'oldie' but 'goodie'; nice soft fragrance; great garden daylily!

An oldie but definitely a goodie!

This was my 1st daylily and still my favorite. Love the clear yellow blooms.

HYPERION persists here in west central Florida, zone 9b. It has only managed to bloom once, but that was enough to make me love it, grin. I've grown it since '96, and moved it when I moved the rest of the collection. I actually have an older daylily cultivar, but it is much newer (to me) and has not bloomed yet.

Deliciously scented, with flowers on tall stems near nose level, and reliable. I have newer varieties but friends still ask for divisions of this old favorite!

Mead FB (1924) 40" tall, Fragrant
