Phlomis fruticosa

Jerusalem sage

9cm pot £4.99 Buy

  • Position: full sun
  • Soil: any fertile, well-drained soil
  • Rate of growth: average
  • Flowering period: June and July
  • Hardiness: borderline hardy (may need winter protection)

    In June and July, distinctive whorls of hooded, golden yellow flowers are strung like beads at intervals above sage-like, aromatic, grey-green leaves. This spreading evergreen shrub forms a neat mound and even after the flowers fade, it retains a dramatic presence in the border, with architectural seedheads that look wonderful among late-flowering perennials and grasses. Thriving in hot, sunny positions, it will cope with drought once established. Try it towards the middle of a sunny mixed or herbaceous border, or as part of a scheme with silver-leaved plants.

  • Garden care: In mid-spring shorten any frost-damaged stems, cutting back to just above a healthy bud. Remove any weak or diseased shoots, cutting cleanly back to the base. Avoid excessive winter wet and offer winter protection in colder parts of the country or when temperatures really drop.

  • Q:

    How do I get it to flower again which it hasn't for years after doing well. I've fed it, coaxed it, pruned and cut it hard back but nothing works. I'm about to dig it out.

      I wonder if there is something overhead that is casting shade as these plants will only flower well if they get lots of sun. Pruning at the wrong time of the year can also prevent flowers forming, so this ideally be tackled in spring. As for feeding, sulphate of potash is the thing to use as this encourages the production of fruit and flowers. It is worth keeping in mind though that Phlomis are not particularly long-lived, so if it is getting plenty of sun and all the other factors have been taken into account, then perhaps it is just time to replace it.
