Red is my favorite color, and I have a lot of gorgeous red daylilies, some of which have already been mentioned here. My top five are all great performers with excellent rust resistance and fabulous red color.
1. Spacecoast Little Red Ninja
This plant is a monster: tall, sturdy scapes; huge, brilliant red ruffly blooms; fast increaser; highly rust-resistant; very long bloom period
2. Insider Trading
This was #1 until edged out by Spacecoast Little Red Ninja. Tall, fast increaser, gorgeous blooms, never a speck of rust, lots of proliferations
3. Caught Red Handed
This one is a top performer here. Beautiful color, lots of proliferations, well-branched, long bloom period
4. Chicago Apache
This is an older cultivar but is a winner in every respect.
5. Desert Flame
I love this plant, but it does fade a bit in the hot afternoon sun.
I started out by going through my list and including every plant that was rust-resistant and had good red color. I ended up with eight. With regret I cut Passion for Red, Bill Fall, and Whooperee because they were not as good bloomers as the others.
I have other reds I like, too, but they are more rust-prone.
I have some new ones I expect to complete for the top spots next summer: Bukharaa Spice, Kaskel Super Red, War Horse, Mount Doom. We will see! I have a lot to look forward to.
