As a comment about Daylily (Hemerocallis 'Thanks Two Friends')
A comment that is on one of the photos but that bears repeating is that this cultivar has very unusual stamens! The stamens (that hold the anthers, or pollen), are actually attached to the petals!
This may make it more difficult to use as a pollen parent since you can't just pluck the stamen to dab on other plants. I don't know whether the pollen is actually fertile or not, but if you attempt to pollinate with this, you'll need to either rip a whole petal off (to which a stamen is attached) or use something else (like a Q-tip) to collect the pollen for dabbing.
Edited to add: This was my first blooming daylily (by far) in my garden for 2016. I've had 5 blooms on it for the early 2016 season and they have all been beautiful. Holds up VERY well, even after rain or long hot days. In 2015 (first year in my garden), it was a tough pod parent--although it did take multiple pods from a very particular pollen parent which it seemed to prefer over others (Starman's Quest)--and an average pollen parent.
