Also known as: Holy Hay

Soft, elegant and full of movement, Sainfoin is a true standout in any wildflower or meadow-style planting.

Its delicate spikes of pink, veined flowers rise above fern-like foliage, creating a light, airy display that gently sways in the breeze. Flowering from late spring into summer, it’s a magnet for bees and other pollinators.

Beyond its beauty, Sainfoin is also incredibly beneficial for the soil. As a nitrogen-fixing plant, it helps improve soil fertility naturally - making it a fantastic choice for both ornamental and productive spaces.

Traditionally grown as a forage crop, it’s now gaining popularity in gardens for its drought tolerance, wildlife value and soft, romantic look.

A Simple, Natural Method

For an easy, natural approach, sow seeds directly onto prepared soil.

Clear weeds and debris, lightly rake the surface, and broadcast seeds evenly. Gently press or rake them in to ensure good seed-to-soil contact.

This works particularly well for larger areas and wildflower meadows.

For Best Results

Sainfoin prefers less competition, so a bit of preparation goes a long way:

Remove weeds thoroughly

Avoid overly rich or heavy soils

Sow onto a free-draining surface

Lightly firm seeds into place

It performs best in poorer soils where more aggressive plants won’t outcompete it.
