Product Information

A Forsythia with year-round interest, this sought-after garden gem will give you the benefit of three seasons of beautiful colour.

In spring, the bare branches become smothered in a profusion of golden-yellow flowers, and these are followed in summer by dark green leaves that glow with bright silver veining. Then in winter, after the leaves have fallen, its deep purple branches take centre stage.

More shade tolerant than other varieties, this deciduous shrub will bring impact and interest to your garden from months on end - truly amazing.

Easy to grow and compact enough for a large pot, anyone can bring this fabulous plant into their garden, and you can be sure that your friends and neighbours will not have one!

Supplied as an established plan in a 9cm pot, ready to be potted on or planted out.

Care Information

Planting Advice for your Forsythia collection:

  • Best in a sunny position protected from hard frost which can damage fresh shoots.
  • Dig a planting hole 3 x wider than the roots of the shrub you're planting and mix some well-rotted compost or manure with the soil from the hole and use this to re-fill one the shrub is in place.
  • We've found that a square hole is better than a round one as the new roots, once they reach the edges tend to grow in a circle round the circumference of the hole whereas when they reach the corners of a square hole, they find it easier to grow through.
  • Before planting soak container-grown shrubs thoroughly and allow to drain.
  • Remove the plant from its pot and tease out a few of the roots.
  • Add Mycorrhizal fungi to the roots when planting to help plants establish quicker.
  • Place your shrub in the hole at the same level at the pot and refill the hole with the earth removed (backfilling).
  • Firm in the soil with your heel, avoiding the root ball and then water well.
  • Mulch around the base of the plant with a collar, compost, gravel, bark etc.
  • If you’re planting into pots, place some old rocks, stones or gravel in the bottom of the pot for drainage and ballast.
  • Use the best compost you can buy and some sand or grit for drainage.


 

Aftercare advice for forsythia:

  • Plants enjoy regular watering and don't like to dry out. It's especially important to keep plants well-watered while they establish, especially if planted up in a pot.
  • Feed twice a year - in spring and summer - while in full growth.
  • Mulch plants every winter - our straw mulch is ideal


 

Pruning Advice for your forsythia:

  • Prune after flowering in spring, to remove any misplaced or damaged branches.
  • After pruning, mulch with a 5-7cm (2-3in) layer of well-rotted compost or manure.
