We had a very pretty display of antirrhinums in our polytunnel this year, grown from seed imported with some soil previously in one of our outside beds. Lovely crimson with a yellow flash.
Out on the plot Verbena comes up like mustard and cress, as does golden feverfew, dill, flat leaved parsley and bronze fennel, plus calendula and cornflowers, mullein, echium and candytuft. They look delightful together too, and the insects adore them.. love these "Gifts from God" that appear like this and give so much pleasure
(Hoping the Cerinthes join the part for next Spring too
)
