The dark purplish-bronze, finely textured, licorice scented foliage makes a beautiful addition to the perennial border or the butterfly garden. Mix Bronze Fennel with yellow and chartreuse foliaged and flowering plants for a great combination. The foliage and stems are utilized by the Eastern Black Swallowtail, Baird's Swallowtail, and Anise Swallowtail as a caterpillar host plant. For optimum health and vigor plant Bronze Fennel in a full to mostly sunny site, in a well-drained, fertile soil. It can be grown as a reliable perennial in gardens and landscapes as well as in containers, either as a specimen plant or in mixed company.

If your Fennel starts to bolt, a.k.a send up flower spikes, remove them to help extend the life of your plants and keep them looking great throughout the growing season.

Grows To: 24-30''H x 30-48''W

This is the average expected mature height by width in feet or inches. Feet are represented by a single quote and inches by a double quote. Parentheses are used to indicate that the plant can potentially reach that dimension, although the sizes outside of the parentheses tend to be more typical. Under poor growing conditions plants may be slightly to significantly smaller, whereas excellent growing conditions can produce larger more vigorous plants.


USDA Cold Hardiness Zones: 4,5,6,7,8,9

USDA Cold Hardiness Zones were established to give gardeners, horticulturists, farmers, nurseries, and landscape architects a universal way to describe where a plant will survive with regard to average winter lows for a region. And these are averages, here in zone 8B ('A' represents the colder half of a zone and 'B' represents the warmer half of the zone and they are separated by about 5oF) we have seen single digits but that is the exception but should be noted by the daring gardener. Each zone is separated by 10oF and the map was updated in 2012. We will continue to use the 2012 map, as the 2023 version is unrealistic. Our zones do not always agree but we try to use our own experience as to what can be depended on to return or have known reputable gardens and or horticulturists to reliably grow that plant in zones that are usually colder but sometimes warmer than what other resources have available. For more on stretching your cold hardiness zones see the ""Growing on the Edge Growing Guide". If you do not know your zone you can find it by clicking on the "USDA Cold Hardiness Zones" link here or above.


Outdoor Light: Full sun, Mostly sunny, Part shade, Part sun

  • Full Sun - 8 hours or more of direct sunlight;
  • Mostly Sunny - about 6 hours of direct sunlight;
  • Partial Shade or Part Shade - about 4 hours of direct sunlight;
  • Partial Sun - about 2-4 hours of direct sunlight;
  • AM Sun or Morning Sun or Cool Sunlight - cool sunlight like early in the day, like in an eastern exposure, or very late in the day but normally in the shade during the heat of the day;
  • Light Shade or Bright Shade - bright indirect sunlight for much of the day;
  • Filtered Shade - may receive some amount of direct moving sunlight like through trees but usually not for any extended period especially during the heat of the day;
  • Shade or Deep Shade - no or very little direct sunlight, especially not during the heat of the day.


Do you know the many benefits of a proper organic mulch? Click here to learn more.

A breathable organic mulch is not only aesthetically pleasing (looks nice) but can:

  • Help to improve soil organic matter as it breaks down.
  • Provide shade for the soil to help reduce moisture loss and prevent weed seed germination.
  • Provide soil microbes, mycorrhizae (beneficial fungi), earthworms,and even nematode predators the necessary organic matter and ecosystem to thrive while their actions aid in improving soil tilth and or friability (think of this as the ease with which roots are able to penetrate the soil).
  • Provide insulation to protect the crowns of tender perennials and die-back perennials giving gardeners up to an extra half a zone of winter warmth allowing us to grow that which we normally could not.
  • Provide soil temperature moderation preventing premature soil warming in winter and providing a cooler root zone in summer.
  • So which mulch is our favorite? Our preferred mulch is Longleaf Pine Straw which has: a natural weed preventative for the first year after it is applied; it is sustainably harvested; and it provides protection from soil erosion and doesn't float away, and yet is still both insulative and breathable; while Longleaf Pine Straw appears to last the longest in the garden and landscape in our opinion as compared to Loblolly.
