teasels are in flower and will set seed soon, or the goldfinches will eat them. Nature sows most seeds in the summer/autumn. some germinate quickly and grow slowly in mild periods in the winter. some germinate in spring. Some won't germinate until they've had winter. that's the native wildflowers like teasel
A lot of the non native 'bee plants' are not so hardy.
If I was doing something for kids it would probably be something quicker. one of those corn field or annual wildflower mixes so the children can see it through in one season.
verbena is great but lots of people on the forum were having trouble germinating it this year and echinacea is a perennial that may not flower til the second year. I'd sow them but with something more reliable to back them up.
