Another Byron Martin hybrid thats part of the Angels Series, Angels Lemon Zest has outdone itself with bold yellow blooms that flare outward and easily reach 6 wide. When its upright growth reaches 4-5 tall, buttery yellow flowers appear in profusion and nearly cover the entire plant. Given proper growing conditions, it can bloom intermittently from spring through fall. It has an intoxicating nighttime fragrance that adds to its appeal.
