Buy Smyrnium perfoliatum perfoliate alexanders: Useful for illuminating partial shade

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun to partial shade
  • Soil: moderately fertile, moist but well-drained soil
  • Rate of growth: average
  • Flowering Period: May to June
  • Hardiness: fully hardy but short-lived

    An attractive addition to the woodland edge or mixed border, this upright biennial will put on a showy display in late spring and early summer. Its stout stems are clothed in leaves, which are green and feather-like towards the base, but sulphur yellow, and with a simpler shape nearer the top. Its tiny flowers are produced in rounded clusters, which are a similar colour to the uppermost leaves. It makes a very handsome foil for rich plums and purples and also looks great when cut and added to a vase.

  • Garden care: Cut back to just above ground level in autumn. A generous self-seeder if happy in its spot, it will soon form a generous swathe. For this reason, it is currently illegal to plant, or cause it to grow, in the wild.

Plant up summer containers

After the last frost date, plant up containers with tender flowering bedding and reliable foliage plants. Line terracotta pots with polythene, taking care not to cover the planting holes, to reduce water loss through the porous sides of the pot.
