Commercial Floriculture

Floral Development

• The elongation of the stem bearing the spadix begins about one month after expansion of the subtending leaf.
• This is subtending by a showy leaf-like structure called a spathe.
• The cycle of the leaf and flower emergence varies with the season.
• 3 to 8 flowers per plant per year can be expected.
• The Anthurium flower is a spadix or inflorescence spike, cylindrical in shape, bearing up to 250-300 inconspicuous bisexual flowers arranged in a series of spirals.
• The spadix and spathe are borne on a leafless stem or peduncle.
• Commercial flower harvesting takes place when approximately three quarters of the stigmas along the spadix have become receptive.
