As a comment about Daylily (Hemerocallis 'Gentle Shepherd')
As a semi-evergreen, Gentle Shepherd is not particularly happy in my garden. It seems to bloom every other year and has not increased much. The flowers are a creamy white. The scapes are short for me and the bud count has been very low. Overall I have been disappointed in this plant. It is in a large raised bed where it gets lots of midday sun. I was recently told by a hybridizer that GS is not a good plant for my area. I'm inclined to agree.
