How to Grow Katniss
As mentioned above, katniss should be planted in areas where its roots will be in standing water at least some part of the year. They prefer full sun but will tolerate some shade, but if you grow it in a shady location, the plant will flower less. Once its roots have taken hold, katniss plant needs little other care provided they get sufficiently wet soil occasionally.
Once established, katniss will naturalize in your garden. They spread by either self-seeding or rhizomes. If you wish to keep katniss from spreading too far, be sure to remove the flower stalks as soon as flowering has faded and divide the plant every few years to keep it a manageable size. If you choose to try growing a potentially invasive variety of katniss, consider planting it in a container that can then be submerged into the water or buried in the soil.
You can plant katniss in your garden with either divisions or seeds. Divisions are best planted in spring or early fall. Seeds can be sown in spring or fall. They can be direct seeded to the location you wish for the plant to grow or can be started in a pan that has dirt and standing water.
If you wish to harvest the tubers of the plant, this can be done at any time, though your harvest may be better mid-summer through fall. Katniss tubers can be harvested by simply pulling the plants up from where they are planted. The tubers will float to the surface of the water and can be collected.
Whether you are a fan of the plucky heroine of The Hunger Games or are just looking for a nice plant for your water garden, now that you know a little more about just how easy growing katniss is, you can add it to your garden.
