Standard operating procedures for Northern Lights. According to the website, during June and July, they propagate by splitting plants into single fans and place them into two gallon tree pots. They inventory everything in the fall and list for sale on the website. They normally sale during the fall, winter, and spring...maybe they sold out early this season. May is the month for shipping, but I usually get mine late April. You get the single fan and any additions in the pot. Last year I got all double and some triple fans with my order. All of the plants bloomed within a few weeks. Now that I know their setup, I start checking the site in early November.
I got notification that my plants for this year shipped on Monday, April 22nd, and I should receive them today.
