You are buying 15+ FRESH Confederate Rose, Cotton Rose Double Hibiscus (Hibiscus mutabilis) seeds PLUS planting instructions, including a color photo for seedling id.  
Neither a Rose nor Confederate, this perennial (Hardy to zone 7) Hibiscus is a native of China, but performs wonderfully in the the southern US and can even be grown as a container plant in northern states if brought in during        the winter.  
Confederate Rose has 'mutant" blooms in the fall, meaning the blooms change  color as they age.  Starting  off white, they change to a light pink then dark pink as the day goes on.  You can, at times, have all three colors on your  bush at once which is really an awesome sight!  These will grow to 10" and prefer full sun but will  tolerate part shade.  They  grow in poor, well draining soil but will do best with regular watering.
These can produce blooms the first year  from  seed, but will have best blooms as the bushes get older/larger starting in the 2nd year.
