If it is just the seed leaves then no need to worry,it`s great when you can get a plant to be ready for it`s final home and still have the seed leaves-but that is mostly cosmetic.
I sell hundreds of plants a year-and one tip,if the seed leaves are there when you buy you know it was well grown,but the opposite is not true- a perfectly good plant may have lost them.
Sorry- does that sound silly?
