Larkspur Flowers are irregularly shaped and bloom in a loose, vertical grouping along the upper end of the plant's main stalk. Larkspur is actually a very complex flower consisting of both petals and sepals. Larkspur grows to their full potential in climates with cool, moist summers. Larkspur, with tall spikes, makes excellent Cut flowers. Two varieties of Larkspur are ideal as cut flowers - Consolida ambigua and Consolida Orientalis. Larkspur flowers tend to be fragile and relatively short-lived in the vase (under 7 days), making production for local markets more lucrative.
