HOW TO PLANT HIBISCUS SEEDS


The hardy perennial hibiscus, also called rose mallow or swamp rose, adds the beauty of a tropical hibiscus to the garden, but can withstand cold winter temperatures that kill the actual tropical varieties. Here’s how to grow hardy hibiscus in your garden!

PLANTING

  • Plants can be purchased from nurseries or started from seed.
  • Seeds can be sown indoor 12 weeks before the last spring frost. 
  • Soak seeds in warm water for one hour before sowing.
  • Seeds can also be sown outdoors after the last expected frost date.
  • Plant the hibiscus where it is not exposed to strong winds to avoid breakage of the long stems.
  • Space plants 2 to 3 feet apart.
  • Mature plants can be divided in the spring
