Seedbox (Ludwigia alternifolia)

Plant name:
Seedbox (Ludwigia alternifolia)

Seedbox is a raingarden plant that provides good texture when planted with red and blue Lobelias and sedges.

This plant has excellent fall color and winter interest.

It grows about 2-feet tall and 3-feet wide.

It will self-seed but does not crowd out other plants in my experience.

Why I chose this plant:
I plant seedbox because of the seed head. It is a tiny box with a small hole for the dust-like seeds to sprinkle out of. The seed heads will persist through the winter and look very cute with their snow caps. Also, it provides structure for a raingarden to keep the soil covered. The red fall color is amazing.

I see many tiny bees visiting the yellow flowers in June and July. The humming birds will use it as a perch when they are visiting the cardinal flower.

Seedbox grows best in raingardens and swales. It likes to have moist soil but not standing water. Plant it in full sun for best fall color.

Where to view this plant:
You can see seedbox at Shaw Nature Reserve in the raingarden demonstration. 

Missouri Botanical Garden 

Where to purchase:
Seedbox is for sale at most native plant retailers.

  1. Thanks for introducing me to a new species. Can you bring seeds to the November exchange?😉

  2. Besa, I have them in my yard this year, grown from seeds you brought to the seed exchange in November last year. They flowered even though they are only about 6 inches tall. thanks!

  3. Seedbox has been one of my favorites especially shaking the seeds from the box. Thanks for the great photos showing its growth cycle.

  4. Thanks for this info…I’m just getting started on our rain garden in Bowling Green…and I will plant it🌱
