#1 quite possibly Lobelia siphilitica - Great blue Lobelia.

#2 Gnaphalium or Pseudognaphalium - Cudweed sp. I believe.

Wow thanks! After looking them up I think you are right in both. They must be from a seed packet mix that was scattered a year ago and never germinated til now.

You are welcome! After the Lobelia blooms it will produce plenty of seeds. Unless you want many plants deadhead most of the stems. I like these but they can get out of hand.
