Random flower seedling ID

I thought I would try to figure out the identity of some of my random flower seedlings. Join me if you like and win fabulous prizes!*§^

*Prizes not that fabulous. Mostly kudos and seeds saved from seedlings.
§Prizes not at all contingent on winning and quite definitely contingent on actually growing any of these seedlings into successfully flowering plants.
^Prizes also contingent on you wanting to give me your address and grow my no-longer random varieties.

I'll start with the seedlings that I think I have identified.

Lupin
   

Marigold
   

Zinnia
