Zone 8B enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

• Grows to 4-5 feet tall — plant toward back of borders
• Flowers attract cats similarly to catnip — protect if needed
• Roots are harvested in fall of the second year for maximum potency
• Attracts earthworms to the surrounding soil — excellent for soil health
• Self-seeds freely; deadhead to control spread

Companion Planting

Avoid planting near: Too-close planting where it will shade shorter crops
