Basic Plant Information
 
Blue False Indigo
  • I am a vascular plant with no woody stems above ground, so I am herbaceous.
  • I do not keep leaves year-round, so I am deciduous.
  • I die back in winter but regrow in spring for many seasons, so I am perennial.
  • I can grow 3 - 4 feet high and 3 - 4 feet wide.

Maintenance Notes
 
  • Dormant in winter.
  • Flowers can be cut for an indoor vase.
  • Pruning or cutting back before winter is optional but not necessary.
  • Trimming or shearing foliage after bloom helps maintain rounded plant appearance.
  • Trimming may eliminate developing seed pods which can be visually pleasing in appearance.
  • Stems break off on their own and blow away, or they can be removed.
 
  • In late fall and into winter the leaves turn silver-gray and the seed pods turn black.
  • When watering, hold hose to base of plant for a count of 5 seconds.  Water should reach all roots.
  • Avoid sprinkling water on the leaves.
  • Requires average amount of water.
Average watering: water two times per week during the summer and once per week during the rest of the year.

Seeds and Rhizomes/ Tubers/ Roots & Shoots
In the fall, stems with seed pods break off at ground level and tumble in the wind to a new location. Over time, plants develop slowly expanding clumps with deep and extensive root systems.
 
 
Plant Life Cycle
Plant Life Cycle:
  • All plants start life as a seed.
  • The seed turns into a sprout when it grows roots.
  • The sprout becomes a seedling as grows a stem and leaves above the ground.
  • After the seedling becomes an adult plant it will grow flowers.

Plant Life Cycle continues:
  • After the flowers finish blooming, each flower turns into a seed.
  • When the seeds fall down to the ground, the plant life cycle starts again.
  • Each seed can become a plant if it has the food, water and space that it needs to grow.
