These are some of the happiest little flowers, opening just as the summer season begins. Called ‘sundrops’ by some, for obvious reasons, and ‘evening primrose’ by others, for the way they open mostly at dawn or dusk, and Oenothera by a plant-loving nerd like myself, they are, no matter what you call them, bright and cheery harbingers of the sunny season.
They can also colonize a patch of the garden quite quickly, perhaps too quickly if you have strict boundaries. Personally, I like a tough little cookie, especially when it brightens a summer morning.
