Well, from planting over 400+ new daylilies this year, and every single one of them was planted in the same compost/manure/peat soil mix, there are definitely plants that just take a bit to get going. I had a few plants put on foliage and even try to bloom with only being in the ground a few weeks. I had a few that I thought just straight up died, but a few weeks later new growth came marching from the ground.
And I even had a few that did, just straight up die. (lost 4 out of 400, I think I did OK)
Heat, water, fertilizer all come into play also. Everyone has a different method, but I did read a few research papers that indicated that best growth was seen when Hem's where planted in 1-1-1 manure. So I did mix a decent amount of dehydrated manure in with my other amendments., since my base soil is useless red clay.
