This is my mid-late, late, and late late list. I have several others that say they are late but it's the first year for them so several bloomed much earlier than they would normally. Most of these are either still blooming or are just starting for me now.

Ginny - What is your very latest to bloom? That's a nice list you have compiled.

I looked at last year's pics and
Woman at the Well
Autumn Jewel
Going Bananas
Were blooming in October

When I Dream
Big Smile
Genesta
Sultans Expression

were still blooming in September

Those were my absolute latest. Some were on reblooms. There were more in late August but I'd have to look.

GIVE ME EIGHT started sometime the last week of June, which would make it about a Mid Late here. (I don't always record the exact FFO and LFO dates, but I DO mark an "X" for bloom during roughly quarter periods of the month: 1st-7th, 8th-15th, 16th-23rd, 24th-end.)

FROM THIS MOMENT ON is somewhere in the Late to Very Late bucket (it is registered as a Very Late), but I don't have enough of a track record (only 2 years?) to say which (plus it is growing in terrible conditions - shade, not enough water). This year FFO was somewhere in the 3rd quarter of July (16th or after).

Poly that is a nice late one. Blooming in your zone starting in July is very late indeed.

Moving into the late season here in zone 7, on August 10 I have the following plants blooming with buds to go

AL'S PEACH TOWER
LAST BLAST
CLEVER ENDINGS
PARTY EVERY DAY
YADA YADA YELLA
SNEAKY GIRLS (rebloom)
WEBSTER GIRLS (rebloom)
MEAN GREEN (rebloom)
CELEBRATING WOMEN (rebloom)
and many of my own seedlings under evaluation

plus from other hybridizers
WELDING THE TITANIC (Bremer) a bud building sib to FIRE FOUNTAIN
HAROLD STEEN (rebloom)
and my very favorite....(pictured)
CAROLINA CARNIVAL (Santa Lucia)
It has a LOT of buds to go and has such bright color on these cooler mornings. I think it is the best of the "CARNIVAL" series because the colors are so clean. The petals are pastel orange.

Gorgeous Judy and love the list

Carolina Carnival is very nice! Nice list of lates

Daylily (Hemerocallis 'Autumn Blaze') Go out with a blaze!
This plant is like a lit torch and very prolific and late.

Ones that have sent up scapes late and haven't bloomed yet:
Bluebird Butterfly - I didn't think it was going to bloom this year, but it sent up a scape last week. Much later than last year.
Oceanside
Moses in the Bulrushes

Also, I am seeing rebloom this year on some that haven't rebloomed before. I can only think it is the heat causing it. At least something good from our unusual heat,
Rebloom on:
French Tudor
Barbara Mitchell
Linda Sierra
Siloam Art Work

Blooming today with more buds on deck:

Carol you were right We have the same plants blooming.

Genesta
The only two that is left to bloom is the mamoth Genesta clump and After Awhile Crocodile

Mike,
I first heard of Genesta from you, so thank you for that great lead. Now I hope to learn what bud building is by watching it happen on Genesta.

Same here. Thanks Mike

Today was the last bloom that is not rebloom. 'Cheetah Wheelies', who is a resident in a kiddie pool under the oak trees.
