Avoid heavy, wet soils.

Deadhead to encourage additional blooms.

Divide clumps every few years to maintain vigor.

🌼 Yellow flax is especially beautiful when planted in masses, along pathways, or combined with other sun-loving perennials for a bright, natural look.

If you'd like, I can also suggest companion plants that pair well with yellow flax.
