I was surprised when daylilies showed up on the schedule a second time, when there are so many other plants to cover. I know they are popular, a big portion of the database, etc... But I am not sure they need to be covered every year. Especially if there is to be a structure to article topics. It could get repetitive having plants repeat each year, and the article topics repeat as well. For instance, there are a few ways to divide a daylily, like, use a knife or use a screwdriver, or cut with shovel, or rip apart with your hands... But it is still the same principal of get the thing out of the ground and into pieces and then replant. Without following a structure for articles, it allows for topics that might not be covered otherwise. This is for plants that would repeat weeks. I don't think I put into words what I meant very well...
I like the idea of hosta having their own week, separate from shade gardening.
I think one thing to consider is how much it takes to put on a "week" and if ATP has enough people to write articles, and enough forum moderators to manage getting the information together for Trish to go for twice a month. I started asking people about articles, etc for daylily week months ago. You need to consider when the type of plant blooms, or gets divided etc, so your writers have a chance to get pictures to go with their articles.
