Grow-A-Long Greater Quaking Grass (Briza maxima)

I found this grass did well from an Autumn sowing, the seeds germinate easily, growing strongly over winter, producing bigger plants earlier than seeds Spring started.

Officially this grass has a hardiness rating of H6 (-15°c), however, I have found this plant can suffer cold shock (foliage bleaching) if plants are exposed to extreme temperature swings following planting out.

For this reason, I have reduced the official hardiness rating for the purposes of the Grow-A-Long, to H4 (-5°c).

The hardness of plants is reduced by keeping them too warm in the greenhouse.

Give plants a good long hardening off period in late winter and be ready with horticultural fleece, a cloche or cold frame after planting if the weather is extremely cold.

You can of course plant in pots and initially locate them in a sheltered spot.
