'Where summer is winter' refers to the fact that we get our bad weather in the summer. Winter is mild but summer is blistering. Also, in the wild, many plants go dormant in the summer.
Daylilies in the lawn refers to daylilies in flowerbeds adjacent to the grass. DH gets a little too aggressive with the lawnmower and can't tell the difference between daylilies and grass.
I used to have some daylilies in a shallow section of the pond but they eventually died out.
The 5-year old plants are semi dormant now but I'll try to remember to take a picture when they start growing again.
