Cream Gentian has unique, glossy leaves and cream to light green flowers that are nearly closed at the tips. Blooming occurs in late summer and lasts a month to a month and a half. Flowers are pollinated almost exclusively by bumblebees. Although its color ... and stature can cause it to get a bit lost in a crowded prairie, it can be a great specimen plant in the garden. Prefers consistent moisture and cooler temperatures, and the leaves can become bleached or even scorched during the hot, dry summer months.
