fennel (Foeniculum vulgare)
Fennel is a recurring problem along Taroona's foreshore. It is a tall, multi-stemmed plant, with soft, fine, feathery foliage. Its most distinctive feature is its strong aniseed-scent. Left to its own devices, it will gradually takeover coastal areas.
Dispersal: Its seeds are numerous, spread by animals, in water, and in garden waste.
Control: This weed will keep re-sprouting if you are not very thorough with removal. For small plants, dig out the tap root. For large plants, cut and paint as close to the ground as possible. Seedheads should be bagged and removed. Smaller plants can be left to rot on-site.
