I sowed some seeds of Alpine Aster, but had to move the soil (with the seeds within)
to another place since a bug (probably a very young black slug) was gobbling down
the other seedlings. A few plants have now sprouted, but I have no idea if they are
asters. Can anyone describe me a seedling, please? (Unfortunately I cannot send
a picture, but the seedlings have long, thin cotyledons slightly widening at the end).
