**1. Planting Location:**
- Choose a well-drained planting location with full sun to partial shade. Scabiosa generally prefers full sunlight, but it can tolerate some shade.

**2. Soil:**
- Provide well-draining soil with a neutral to slightly alkaline pH. Sandy loam or loamy soil is ideal. Improve heavy or clayey soils by incorporating organic matter.

**3. Planting Time:**
- Plant Scabiosa caucasica 'Perfection Blue' in the spring or fall. This will allow the plant to establish itself before extreme temperatures.

**4. Planting Method:**
- Dig a hole that is slightly larger than the root ball of the plant.

- Backfill the hole with soil, tamp it down gently, and water thoroughly.

**5. Watering:**
- Keep the soil consistently moist, especially during the establishment period. Once established, Scabiosa is moderately drought-tolerant, but regular watering during dry spells is recommended.

**9. Support:**
- While Scabiosa generally doesn't require staking, if the plants become leggy or flop, you can provide support or consider pinching back the tips to promote a more compact form.

**10. Division:**
- Divide overcrowded clumps every few years to rejuvenate the plants. This is typically done in early spring or fall.

**11. Pests and Diseases:**
- Keep an eye out for pests like aphids and spider mites. Treat infestations with insecticidal soap. Good air circulation can help prevent fungal diseases.

**12. Winter Care:**
