Finnochio (bulbing fennel and sometimes erroneously refered to as Anise) is listed in the vegetable section. Contrary to what you may have read, Fennel and Dill DO NOT cross pollinate. Pollination across genera is very rare. Cross pollination would only affect the offspring/seeds anyway, not the parent plants.
Fennel, Bronze. Foeniculum vulgare
'Rubrum'. Bronze, feathery leaves give this variety an ornamental character. Makes a dramatic garnish. Growth is not as robust as green varieties. A sweet, anise flavored plant, often mistaken in its early growth for dill, a close relative. Leaves, stems, and seeds are used to flavor pasta, meats, fish, and vegetable dishes. These short-lived perennials are hardy to -10°F, and can reach up to 6 feet tall. Space transplants 24 to 30 inches apart. Finnochio (bulbing fennel) is listed in the vegetable section.
Fennel, Green. Foeniculum vulgare
. A sweet, anise flavored plant, often mistaken in its early growth for dill, a close relative. Leaves, stems, and seeds are used to flavor pasta, meats, fish, and vegetable dishes. These short-lived perennials are hardy to -10°F, and can reach up to 6 feet tall. Space transplants 24 to 30 inches apart. Finnochio or bulbing fennel is a different plant entirely.
Feverfew. Tanacetum parthenium
'Tetra White'. Short-lived perennial, hardy to -20°F. An old medicinal plant, revived to combat modern headaches, as a tea. In the garden it delights the senses with beauty and form.

Finocchio. Foeniculum vulgare
'Zefa Fino'. Annual bulbing fennel produces remarkably thick, rounded, heavy bulbs with a refreshing anise flavor. Grow in loose, fertile soil (slow release nutrient pellets work well). When bulbs begins swelling, pull soil over it to keep it white. Harvest before flower stalks form.
Flax, Blue Flowered. Linum perenne
. Perennial, hardy below 0°F. This pretty border perennial created lots of excitement among visitors last year. The long feathery branches produced loads of small pale blue flowers which opened dutifully each morning with the sun, closing as the heat of the day intensifies. As with ordinary flax, seeds contain linseed oil and can be used in baking.
