White Margined Japanese Anise. I found this most unique variegated Japanese anise in a rare-plant nursery in Japan with pewter colored leaves sporting irregular white margins. And it is amazingly vigorous considering the amount of variegation. As with all cultivars of this species, it flowers here in late March to early April with star-like white flowers, similar to the species, but not quite as large. Site it in filtered sun in a soil with good drainage and uniform moisture. Any where an Azalea is happy, this species will do well. We have had no deer or rabbit related problems with it as with most species in the genus Illicium. Like other Japanese Anise, the seedpods are poisonous.
