The answer is not plant but "plants"! Many fragrances that smell wonderful to humans are highly repellent to ticks. Rosemary, citronella, lemongrass, cedar, rose geranium have all been shown to keep ticks away.
However, the best way to repel ticks is preparation, preparation, preparation with a strong natural repellent! Before you head for the outdoors make sure that you examine the ingredients and concentration of elements that repel ticks. If it is not a chemical like Deet or Permithrin, spray it on your clothing and skin around the foot and hand cuffs and neck where ticks can enter.
