Sounds like you have the makings of a lovely garden, Kyla! What a nice variety of seeds! Hope that body of yours holds up, by dinkum, because we want to see the photos once it's all growing!
I think Rudbeckia hirta is a good example of a plant that resists our attempts to categorize it. I've seen it classified as a perennial, a self-seeding biennial, and an annual. I had 'Denver Daisy' in my garden last year and was pleased to see it sprouting again. Aha, I thought--it's definitely a perennial! Well, then it bloomed and imagine my surprise when it was 'Prairie Sun' -- one of 'Denver Daisy's' parent plants! So it had obviously reseeded and reverted to its parent plant. But if it had *looked* the same I would never have known that it wasn't the same plant re-emerging, but its offspring.
