Fennel, Common fennel or sweet fennel, is a tall-growing perennial that lacks hardiness to survive winters in northern areas. It is most often grown as an annual and can reach a height of 3 to 5 feet. It should be seeded in place in full sun on rows 3 feet apart with plants 10 to 12 inches apart. All the parts of this plant may be used. Harvest the stems before the flowers bloom and the leaves when flowers start to bloom.
Seeds turn brown when ripe and can be dried for later use.
Marjoram produces an attractive bushy plant which grows 1 to 2 feet tall and can be used in borders or as a container plant. It produces small leaves which are light green on top and a gray color beneath. In all areas, except extreme southern locations, it should be grown as an annual although it is actually a perennial. Start seed indoors and set transplant out after the last killing frost. This herb is grown for its leaves which should be harvested just before the plant blooms for full flavor.
