Details

The False Indigo Blue has purple-blue colored flowers that bloom in 12" long racemes on flower stalks above attractive blue, gray-green foliage. The ornamental charcoal pods can also be used in dry arrangements, too. This plant was once used for making dye and is natural to mesic/gravel prairies, rocky river banks and woodlands. This native plant will also attract birds to your garden. Mature size is around 3-5 ft tall. Hardiness zone 3.

Planting & Care for False Indigo Blue

Preparation

  • Easily grown in average, dry to medium, well-drained soil in full sun to part shade.
  • Best in full sun. Tolerates drought and poor soils.
  • This plant is effective in the landscape when used for borders, cottage gardens, prairies, meadows and native plant gardens. Can also be effective in naturalized settings. It looks best as a specimen or in small groups in gardens.

Opening Plant Material

  • Containers - Completely saturate all container plants by putting in a larger container of water until stops bubbling, then remove. You’re now ready to plant.
  • Scroll down to an orange rectangular box and click on “Handling & Plant Guidelines” for illustration on planting each of these types.

Planting containers

  • Plant in March, May – November.
  • Slide plant from pot by tapping on the bottom of the pot.
  • With shovel or knife trim bottom 2" off of the root ball for plants in plastic containers.
  • Rotate the plant to the proper position. Never lift or move plants by the tops.
  • Place the root ball in the hole.
  • Notice where the base of the trunk flairs out from the tree. This is called the root flair. This root flair should show when the tree is planted. If necessary, add soil under the ball so the root flair is exposed.
  • Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer.
  • Backfill the hole with soil, making sure the top of the root ball is visible and slightly higher than the soil around it.
  • Firm the soil around the plant. Water well to settle soil around the root ball.

Pruning - After Planting

  • Containers - Although it is not essential for containers to be pruned after planting, a light pruning for shape, to remove any broken branches from shipping, or to thin out a heavily branched plant will help in the transplanting process and in the appearance of your new planting.

Pruning - Through-out the Season

  • Trimming or shearing foliage after bloom helps maintain rounded plant appearance and obviates a possible need for staking, but eliminates the developing seed pods which are so attractive.

Watering - After Planting

  • Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
  • Beyond the 6 week establishment period, water once per week, unless rains occur.
  • Stick your finger into the soil around 3” to check soil moisture.

Watering - Through-out the Season

  • After the first season, plants should only be watered during extended periods without rain.
  • How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it is dry, give it a good soaking with the hose end (no nozzle) watering the soil only, not the leaves.
  • Stick your finger into the soil around 3” to check soil moisture.
