- Life cycle
The life cycle of Foeniculum vulgare var. azoricum 'Rondo', commonly known as Florence fennel or finocchio, starts with seed germination, typically in the spring when soil temperatures rise above 50°F (10°C). Seedlings emerge and establish a rosette of feathery, licorice-flavored leaves. Once the plant is established, it begins vegetative growth, developing a thick, bulb-like stem base that's harvested for culinary use. During the reproductive stage, usually in the second year, Florence fennel sends up a flower stalk topped with umbrella-like yellow flower clusters, which are followed by the formation of small brown seeds. Seeds mature and, if not harvested, drop to the ground, potentially giving rise to new plants. The plant is biennial, although it's usually grown as an annual crop for the bulbous stem, and completes this life cycle within two growing seasons.
- Propogation
Propogation time
Spring-early summer
Fennel, particularly the Foeniculum vulgare var. azoricum 'Rondo', is most popularly propagated through seeds. Sowing can be done in late winter to early spring, as fennel seeds require a period of cold to break dormancy. Typically, seeds are scattered directly into the garden where the plants are to grow, since fennel has a taproot system that can be damaged by transplanting. The seeds should be sown shallowly, about an eighth of an inch (or roughly 3 millimeters) deep, and spaced a few inches apart to allow space for the mature plants. Germination usually occurs within 1-2 weeks with proper soil moisture and temperatures around 65 to 70 degrees Fahrenheit (18 to 21 degrees Celsius), after which time the seedlings can be thinned to stand 12 to 18 inches (30 to 46 centimeters) apart.
