Ferula communis, the giant fennel, is a species of flowering plant in the carrot family Apiaceae. It is somewhat related to common fennel, which belongs to another genus, Foeniculum, also in the family Apiaceae.
Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
To enhance foliage, remove flowering stems as soon as they appear or after blooming if seed is not required
However, culinary uses of this species are not always safe and poisoning may occur. In Sardinia two different chemotypes of Ferula communis have been identified: poisonous (especially to animals like sheep, goats, cattle, and horses) and non-poisonous.
