Does Feverfew Grow in Arkansas?

Life Cycle Confusion

• Authoritative sources disagree about whether feverfew is a biennial or a perennial. This lack of clarity is probably related to the fact that feverfew is more susceptible to winter-kill during its second year, yet it cannot be strictly biennial because it sometimes survives its second winter and continues to produce flowers. Subtle climatic variations might influence feverfew's longevity, so if you are looking for a long-lived perennial, start with a few plants as an experiment before you an make an extensive planting.

Too Hot, Too Cold

• Feverfew is considered well-adapted only to U.S. Department of Agriculture hardiness zones 5 to 7. This herb is fairly tender in relation to other biennials and perennials. Even in appropriate hardiness zones, it may not survive the winter if unseasonable weather conditions cause it to partially break dormancy during late winter. This can also explain why feverfew is not reliable in climates warmer than USDA zone 7. These mild-winter regions may not be cold enough to drive feverfew into its hardy dormant growing state, so the plant remains susceptible to injury from the severe freezes that occasionally occur in these areas.

Feverfew in Arkansas

• Most of Arkansas falls into USDA zones 8a and 7b. A strip along the northern part of the state is in zone 7a, and a small section of the northeastern corner is in zone 6b. Feverfew is hardy in these zones, so all of Arkansas is warm enough for this herb. The southern half of the state might be too warm, though -- the areas in zone 8 and the warmer parts of zone 7b are questionable because the winters might be inappropriately mild. Feverfew can die back during hot, dry weather, so the summers in these southern regions might also be problematic, especially if you do not plan to irrigate.

Seeds and Soil

• Feverfew is fairly easy to grow from seed, in contrast to many other herbs. Arkansas gardeners can plant seeds directly in the herb garden once soil temperatures are above 60 degrees Fahrenheit; the seeds are small, so stay ahead of the weeds and thin gradually until you have about 12 inches between plants. Soil of average fertility is adequate, but choose a well-drained location because persistently soggy soil can lead to root deterioration. Feverfew tolerates partial shade and full sun; a little shade in the afternoon is preferable in regions with hot summers.
