In Love with Japanese Irises
Japanese iris petal variations
Singles have three falls (large hanging petals). Each fall has a triangular yellow "signal" in the center of the flower and three "styles" (small, upright petals) in the center.
Doubles grow with six falls, each with yellow signals, and three, four or six very prominent styles. The color contrast, number or form of the petals and styles can make one bloom appear merely pretty and the next one look spectacular. Pictured is 'Crested Surf', a double with six petals.
Multi-petals grow with more than six petals, usually nine to 12, each with signals and multiple styles.
