A night bloomer that wafts year round in z10
Zaluzianskya capensis "Midnight Candy" closes during bright daylight into a wipe and purple striped ball about 1/4" in diameter. It opens on dim days, or at twilight, revealing white petals, and releasing a very strong and distinctive fragrance of cake batter. It is a perennial in my zone => and blooms nonstop. It has been in bloom for over two years, and just slows down when it is setting seed.
It is in a fragrant night planter box with Nicotiana x sandarae 'Perfume Deep Purple' and Mirabilis bicolor. The smell of Zaluzianskya capensis overwhelms the other two.
