This is one of my favorite Missouri native wildflowers. It is Celandine Poppy (Stylophorum dyphylum). It has been battered
by the heavy winds and cold for several days. It can take it - even the freeze forecast for tonight.
What I like about it is that it has been blooming for several weeks and will continue to bloom formally months - probably into June. It is draught and deer resistant and grows in partial shade. It is a perennial and once a stand of it is established it will return each year and when the bloom is over the green remains until the frost.
