Gardening in alkaline soil can be challenging, but choosing the right plants ensures a thriving outdoor plant box. Alkaline soil, with a pH above 7, limits nutrient availability, so selecting pH-tolerant species is key. Here are the best plants for your alkaline soil garden:

1. Lavender – Thrives in well-drained, alkaline soil and adds fragrance and color.

2. Yarrow – Drought-resistant and perfect for sunny spots with high pH.

3. Boxwood – A hardy shrub that tolerates alkaline conditions and adds structure.

4. Sedum – Low-maintenance succulents that flourish in alkaline, rocky soils.

5. Lilac – Produces vibrant blooms and adapts well to alkaline environments.

For optimal growth, amend soil with organic matter and monitor pH levels. With these plants, your outdoor plant box will flourish, even in alkaline conditions!
