I received this last spring as tiny little fans accompanied by a refund check due to their fragile condition. I didn't keep the check and the fans grew well. With an unusually mild winter, they haven't been tested for what would be a normal or colder than normal winter yet.
It was the first daylily to bloom this year. In fact, the three scapes were nearly finished blooming before anything began blooming. The blooms had trouble opening in the cool temperatures and probably half of the blooms were blotchy. That may have been due to an aphid infestation (and maybe thrips too) that was difficult to get under control.
It currently has a rebloom scape, so it may be among the last daylilies to bloom as well as the first. Guess that will test the blooms ability to withstand high heat and lots of sun. It's timing for bloom may not have been the best this year. The foliage is holding up well in the heat so far. Many daylilies are settling into a kind of heat dormancy with many outer fan leaves drying up, but 'Tusk' is still actively growing. Here's a photo of 'Tusk' today with the rebloom scape. Growing for another season or two will likely give more accurate info on how it grows in north central Texas.
