In The Garden: Even more plants from aster family.

I am very grateful to everybody with ID help in previous posts, but looks, like I still have problems to identify my collection of aster family plants

1.Is this Coreopsis or Cosmos, or maybe none of these. If one of these, can you tell me why one and not another

#1 - Coreopsis (something like C. grandiflora or C. lanceolata). Cosmos sulphureus is the only cosmos species one can confuse a Coreopsis with, but the former one has much longer disc corollas (and of course there are other morphological differences too).

#2 - Helichrysum marginatum

#4 - Erigeron compositus

 

Agree with these three, thank you

 

# 5 Leucanthemopsis alpina ssp ?

 

all attractive to butterflies....

 

agree, thank you
