from suite101: Easy to grow, herbs are a great addition to any space. Some, however, will try to take over the garden bed.
Most herbs are compact and need minimal space. But there are some that, if left to themselves, will attempt to take over the garden.
An annual plant is one that only lasts for one growing season. Many herbs are annual and will need to be replanted each year. These include basil, chamomile and dill, although dill is very good at re-seeding itself. Annual herbs won’t grow too large, so they can be safely planted in appropriate locations without fear that they will attempt to smother their plant neighbors.
