Here you can see the whole plant. What looks like the pedicel here is really a very long hypanthium (this is why it's called "stemless evening primrose"). The capsules therefore develop at ground level. Note how the sepals are fused and are flared to one side of the flower. Habit--the leaves are so low, the plant tolerates mowing very well (though the inflorescences probably don't).
