Planted 1 Alba False Dragonhead about 6 years ago and it is located in sun all day long. It does not get water except for what Mother Nature provides and has since self-seeded 2 additional plants approximately 4 feet from the mother plant. Doesn't mind poor soil and no water. Love this plant!! It blooms for an exceedingly long time.

Very showy white flowers. It tolerates getting early morning sun and then none in the afternoon. It needs to be kept moist and wilts easily if the ground gets dry. I'm transplanting a bunch into the full sun, over 9 hours of sun a day, so we'll see what happens. Non invasive here and spreads very gradually. After 4 years the original plants have doubled their size. Very pretty plant
