Daylily (Hemerocallis 'Key to My Heart')

Key to My Heart is slow to increase here in southern NH. Other than slow to increase, it's a fantastic daylily with beautiful bloom.

I grew KEY TO MY HEART for many years. I loved this plant. It increased well in my Zone 5 garden. I decided to get rid of it, because the outer petals would frequently "canoe". I wanted the blooms to lay flat and they would not. I would manipulate the bloom to be wide open to only find the outer edges to curl up. I suspect that the petals were not as thick at the edges and thus they curled. I loved the color and the hardiness. I would still grow it not for the canoeing.

I still grow KTMH it grows well here, the coloring is lovely. I do agree with David about the canoeing which is a flaw IMHO. Perhaps this is not an issue in more southern climates.

Hi,

I just received KTMH as a bonus plant and was adding it to my plant list today when I saw this thread! I was hoping to see what others thought of it as it's definitely a pretty one.

I wouldn't care for canoeing either so I hope it lays flat in 7b.

Thanks!

Here's a duplicate thread:

The thread "Daylily of the Day: Key to My Heart" in Plants of the Day forum

I received a large DF of Key to My Heart from Keast Daylilies in September of 2021.

I love this plant. I bought it for its excellent rust resistance score, which it has earned here. The foliage is always healthy-looking, and the blooms are uniform and perfect. I have not seen the canoeing complained of above. I love the color--a deep rose with pink edge. It has a similar look to Roses in Snow, which I also grew, but which did not do well here.

Key to My Heart is very photogenic. It blooms in mid to late April and into May here. It has reached is registered height.

The plant is a slow increaser, like its parent Whooperee, which I also grow. I counted three fans on Key to My Heart this morning before writing this review. It has not yet rebloomed for me either. I am hoping it will with some alfalfa pellets and fertilizer.

It produced one proliferation in its first season here, but none this last season. As it settles in, I am hoping for improved performance, but the plant will always stay in my garden.

This is one of the most vigorous daylilies I grow. It multiplies rather quickly in Zone 9, has heavy substance, and makes proliferations. A win, win.
