Catnip grows well in moist soil and spreads by rhizomes under the ground surface. (Considered a weed in North America).. It can be invasive, like most mints. Plant in full sun or part shade as a container plant or allow it to fill in areas of the garden where nothing else seems to grow. Winter hardy in zones 7-10. Blooms purple-blue or white flowers mid-summer.
Nepeta is a genus of about 250 species in the Mint family. Catnip and/ or Catmint are both known for their aromatic plant oils that a percentage of domestic cats seem to get excited about.
Not considered a culinary herb. Grown more for an ornamental in the garden.
Science has found that Catnip oil, through distillation, is a repellent against mosquitoes, cockroaches, termites and possibly other insects. It's effectiveness is rather weak when rubbed on human skin though.
