WOW! This plant is just glam! They are somewhat late to bloom, but stay in bloom until stem rot catchs up to them. The blooms are so pure white that they look just like an angel! The frills in the center is large in the first few blooms but by the time that the plant is receeding, it get so small that it is almost non-existent. But will grow this plant again!
