A book of First Class stamps approved pharmacy Cast an airy veil with Molinia caerulea subsp. arundinacea 'Transparent’, which provides a mist of darkish beads. Tall molinias always have subsp. arundinacae in their title, but they vary greatly in form and are often wrongly named. Use a specialist nursery (see box). If you can’t find 'Transparent’, grow Molinia 'Karl Foerster’ instead. Also make use of the upright Calamagrostis x acutiflora 'Karl Foerster’, its stems rise like a rocket heading to Mars.
