I am reporting the sighting of three A. tuberosa. They are about 4" tall at this point on May 20.

This sighting is in my native WI perennial garden that was established in 2011. I planted 5 A. incarnata, and 6 A.tuberosa. About May 8, the A. incarnata were visible. Around May 20 I could only find 3 of the 6 A. tuberosa. By May 29, I found all of the A. tuberosa. I selected the date of the 20th since I could find half of the A. tuberosa. Today, on the 29th, the A.incarnata are about 16" in height, and the A. tuberosa are 5" at the maximum. There are yellow aphids on the A. incarnaata, but not on the A. tuberosa. My garden setting is about 1/2 mile from the Native WI Prairie setting (a south-facing site) that reported a 1st sighting of milkweed on May 8th.
