About 30 years ago, my Maw Maw had a plant near her front porch, it bloomed only in the late afternoon and throughout the evening. The following morning the blooms either fell off or closed up. Maw Maw told me the plant name was 4 O'clocks because it only bloomed after 4 p.m.
Now 30 years later, I have these sweet plants through out my gardens. They can be intrusive, but baby plants are easily pulled up and transplanted wherever you'd like. When mine get "leggy" I've been know to cut 'em back...then I either immediately root them or scatter the cuttings where I want 'em to grow! Mine are in full sun, partial shade and full shade areas...all do equally well. They appear to be drought tolerant but they bloom and thrive with moderate watering. The flowers will become seeds...to self seed or harvest and scatter where you want them. Notice mine are pink...I've had yellow, red and white as well BUT they did not over winter...pink must be the hardy variety for my Zone 7 gardens.
This photo is from early this morning...notice the blooms are closed...
This photo is from this evening around 6 p.m...now the blooms are opening and oh how sweet they are!
