FAQs

Does this plant need full sun?

Yes, 'Blue Hobbit' performs best and develops its signature blue color in full, direct sunlight.

Can I grow this in a pot?

Absolutely. Use a well-draining potting mix and ensure the container has sufficient drainage holes.

How often should I water it?

Water frequently during the first year of establishment. Once established, it is highly drought tolerant and rarely needs extra water.

Will bees visit this plant?

Yes, it is highly valued by pollinators and is an excellent choice for a bee-friendly garden.

When should I cut it back?

Prune back the spent flower stems in late autumn or wait until early spring before new growth appears.

Are these flowers good for drying?

Yes, they are excellent for dried arrangements. Harvest them when the color is intense and hang them upside down to dry.

Troubleshooting

Plant growth is stunted or wilting in winter

The soil is likely too wet. Ensure the site has excellent drainage and avoid planting in low-lying areas where water pools.

Lack of vibrant blue color

This is often caused by insufficient sunlight. Move the plant to a location with full, direct sun exposure.

Root rot

Remove the plant, check for mushy roots, and replant in a spot with significantly better drainage, adding grit to the soil mixture.

Setup, Compatibility & Care

Planting

Choose a site that receives at least 6-8 hours of direct sunlight per day. If your soil is heavy clay, mix in horticultural grit or sand to improve drainage. Dig a hole twice the width of the 1L pot and ensure the top of the root ball is level with the surrounding soil surface.

Ongoing Care

  • Watering: Water regularly during the first growing season until established. Once established, only supplement during extreme, prolonged heat waves.
  • Feeding: Generally does not require heavy fertilizing. A light dressing of organic compost in early spring is sufficient.
  • Pruning: Cut back spent flower stems in late autumn or early spring to tidy the plant and encourage fresh basal growth.
  • Compatibility: Pairs effectively with other sun-loving, drought-tolerant plants such as Lavender, Salvia, or Sedum.
