Daylily (Hemerocallis 'Whooperee')

I have plants that trace back to Whooperee lines and they are good plants.
Quite rust-resistant.

Whooperee has been in my garden for 14 years and is a nice landscape plant. It only gets 24 inches high and I have never seen rust on it.

It blooms here in southern Indiana around mid-June through the first week of July. The scapes are sturdy with 2-way branching, but only gets about 6-8 buds.

At one time I had two clumps of it (pay no mind to all the maple tree helicopters on the rocks, lol!). I like that Whooperee stands above the foliage, but I now prefer blooms a little more above the foliage than this.


Sometimes the blooms take on a different look with the white on the outside. This is when I see some of Whooperee's children come through (Key to My Heart, Mama's Cherry Pie)


And sometimes the sun/heat just fades it to a light pink:

I have had 'Whooperee' almost three years now, and it did very well here last year and looks like it should do very well this year. Beautiful blooms good rust resistance here in my garden.

Here is a photo I just snapped of how it looks today.

Great picture of your clump of Whooperee, Larry. What does your branching and bud count look like? I'm having a little trouble seeing that in the pic.

@blue23rose,
I'll check tomorrow and report back.

@blue23rose,
Well, after looking at my 'Whooperee' I think it is too early to give a bud count and branching on it, but it is already doing better than it did last year(I showed a weird branching of only two) with a low bud count under 10. The branching is at least three this year and with the bracts showing placed in three places on the scape it looks like it could possibly be much improved this year. Hope the bud count is also, but I will report back later in the year on it when I can tell better exactly how it performed. The scapes are also already taller than they were last year. So it is looking good.

Thanks for checking, Larry. I only have one clump now and I know it needs to be divided. When I actually looked at all of my pictures of it over the years and saw how low the bud count was, I was surprised.

I have been out of town for a few days. I took these photos before I left but did not have time to post them.
'Whooperee': First blooms of the season on this plant and I Love the how they look.

Very nice, Larry! That first picture shows how clean looking Whooperee's blooms are. I don't remember ever seeing a blotchy bloom.

I have grown this one for three seasons. In this third season, it has fully settled in and been a fabulous plant for an evergreen in my area. It is at registered height and bud count is an amazing 18 on 2 way branching. Bloom is over a long period and always consistent in every way. I will keep this one

I crossed it with one of my 2-year-old seedlings with tall scapes, which is also rust-resistant. Pretty amazed at how strong the 25 seedlings from this cross are. I didn't really focus on that cross but these young seedlings demand my respect. I was going to leave them in solo cups until Nov 1 when I move them to the bed. But I have to enlarge the containers because the roots are pretty aggressive.

I obtained two small fans of Whooperee from Amador in the fall of 2021. I wanted it for its reputation as a rust-resistant plant.

I planted it in a great location in full sun in a new bed I had dug next to my garden shed. All the daylilies in that bed seem to love it, and Whooperee was no exception, quickly greening up and thriving. The next spring it presented me with its first bloom, and I was delighted with it:

It was so bright it was like a beacon I could see across the yard, and it was one of my first daylilies to bloom. It's been early for me both years, blooming in April. Its second season, 2023, it also rebloomed for me.

Also in its second season, Whooperee reached its registered height. It has shown a little rust at the end of the season, but that is all--good rust-resistant performance for this zone. It seems to be a slow increaser, increasing by one fan in two seasons. The blooms are a lovely brilliant red--though they fade by the afternoon in the direct sun. Looking at the pictures I've posted here, I can see that thin white edge Vickie referred to above. I had not noticed this previously.

Recently I posted in the "5 Favorite Reds" thread. Whooperee did not make the cut. I have reds that have clumped up, have been better bloomers, and don't fade in the sun. But I will keep Whooperee. It's a pretty, rust-resistant plant with a nice height, brilliant color, and a long bloom period that starts early. It deserves to stay in my garden.
