Don't
remove the caterpillars: Bronze fennel is a larval host
plant for eastern black swallowtail butterflies. The adult
butterfly visits this perennial to lay its eggs. When
caterpillars hatch, they're sitting right on a nutritious food
source. |

Add
a nectar source nearby: Butterfly bushes and other
flowering perennials provide nectar for the adult
eastern black swallowtail (Papilio polyxenes). |

PLANTING
BRONZE FENNEL in
your garden is like cultivating mist.
The feathery foliage is both fluffy and wispy. It makes a
heavenly backdrop for large, coarse flowers such as black-eyed
Susan or purple coneflower. Bronze fennel is so delicately
soft you'll want to pat it. Grow it and you'll frequently find
yourself identifying it for visitors enchanted by this
perennial's fine, hazy foliage. Glossy, threadlike leaves
start off as smoky purple or bronze plumes before fading to
gray-green. |

SEASONING
Bronze
fennel is an herb, so you can use the leaves, stems, flowers, and
seeds in all sorts of culinary delights. The flavor is often
compared to anise, sometimes to licorice. But don't overlook this
plant if you don't plan to use it in the kitchen you'll
love it in the garden as an ornamental addition. Bronze fennel is at
home mixed into beds of perennials and annuals, so don't relegate it
to the herb garden. In fact, fennel should be planted away from
dill, with which it sometimes cross-pollinates
unfavorably. |
|
The
plant's name refers to bronze color of new growth. Both
gray-green and bronze foliage appears on the same plant. |

SIZE
Bronze
fennel's ultimate size varies in accordance with its growing
conditions. When grown in all-day sun in fertile soil, such as clay
or well-prepared garden soil containing plenty of organic matter,
bronze fennel may become 7 feet tall by summer's end. Regular
watering promotes growth, too. Such size makes the feathery
perennial ideal for filling empty corners, standing behind shorter
perennials, or mixing with other tall plants. When grown in partial
shade or poor soil, bronze fennel may stay as low as 3 feet. Lack of
water may stunt its growth, too, though this plant doesn't demand
constant moisture. Trimming lanky stalks (an optional task) promotes
bushiness. |
|
SEEDLINGS
Bronze
fennel blooms at the top of its stalks. Whether you leave the
blossoms intact or cut them off is up to you. The lacy blooms are
pale yellow and pretty and attract lacewings, a beneficial insect
that eats the bad bugs. The flowers are edible, too, as are the
seeds they produce. But seeds that fall from flowers can yield a
flock of unwanted seedlings. Plantlets are easy to remove from soft
soil in clay, not so easy. Seedlings are more prolific in
sunny beds than in partially shaded areas. Poor soil produces fewer
seedlings as well. Some gardeners clip flowerheads early as a method
of population control. Bronze fennel stops producing leaves when it
blooms, so removal of buds to prevent flowering also encourages
fresh plumes of foliage. |
|
Though
the flowers of black-eyed Susan take center stage in this
composition, the bronze fennel growing as a backdrop behind
the bright blossoms make them show off to their best
advantage. |
