Culture
Water
The Blue Star plant has moderate water requirements and thrives in well-drained soils. While it is relatively tolerant of drought conditions once established, it benefits from regular watering during dry spells, especially in the peak of summer. However, it is crucial to avoid waterlogged conditions, as excessive moisture can lead to root rot and other issues.
Sunlight
In terms of sunlight, the Blue Star plant prefers full sun to partial shade. It tends to bloom more prolifically in full sun, but it can also adapt to growing in areas with dappled shade, particularly in hotter climates.
Fertilizer
One of the remarkable traits of the Blue Star plant is its minimal fertilizer requirements. This low-maintenance perennial does not necessitate heavy feeding, and an application of a balanced, slow-release fertilizer in spring should suffice to support healthy growth and flowering.
Soil

Pruning
After the flowering period, typically in late spring to early summer, it is beneficial to prune the Blue Star plant to maintain its shape and encourage a more compact growth habit. Simply trim back the stems to promote a bushier form and prevent the plant from becoming leggy.

- Sow the seeds in a well-draining seed-starting mix and lightly cover them with the growing medium.
- Keep the soil consistently moist until germination occurs, which typically takes several weeks.
- Propagation by Division:
- Divide established clumps in early spring before new growth emerges or in the fall once the plant has finished flowering.
- Use a sharp, clean tool to divide the clumps into sections, ensuring that each division has both roots and shoots.
- Replant the divisions at the same depth as the parent plant and water thoroughly.
