Florida. I see the reviews and they are really nice, but does anyone know how they do in 94
degree weather with a lot of humidity in summer? I live in zone 9 b.

Check on line with Krull-Smith landscaping in Apopka Florida. Frank Smith is the Florida daylilly guru.

I suspect 'Jolyene Nichole' would be OK since it was hybridized in a warm climate (I have it here in Zone 4 too, incidentally). I don't know about Early Bird Cardinal (which is really the registered cultivar 'Endless Heart') since it is hybridized by Apps. You could try asking on the Daylily Forum here on NGA.

I'll request the question be transferred there since there are Florida NGA members who specialize in daylilies.

We have similar weather here in southeast Alabama, and Jolyene Nichole performs very well here.

Since both cultivars are evergreen, they should do fine for you.

There is but a miniscule amount of dormant cultivars that will live for you for past one season.

I live in 9b and the best advice I can give you is ... Don't waste your money or garden space unless you want to treat dormant daylilies as annuals. Even some semi-evergreens carry too much dormancy to survive.

Most evergreens should do fine in your area.

Frank Smith got out of daylilies almost as fast as he got into them. He sold the daylily business to Pete Harry 7 or 8 years ago. If it's orchid-related, Frank Smith/Krull-Smith is the go-to place. Daylilies...not so much.

I am in zone 5 so my experience with the warmer climate is kaput. Both plant does well here in my garden.
Endless Heart is a faster increaser here. Endless Heart also reblooms here consistently. JN occasionally put up rebloom scapes. EH has taller scapes. More above the foliage. Welcome to the daylily forum.
BB Code:

The Lambertsons are your neighbors, as is Jamie Gossard and his spacecoast buyout, so you can grow some pretty nice daylilies there.
