Description

Rare and unusual, Romneya coulteri (also known as the Californian Tree Poppy) produces voluminous, crepe-paper white poppies with golden-yellow centres. Widley admired for its blooms, it begins flowering in early July and goes on until the autumn producing some of the largest flowers in the poppy family – up to 15cm (6in) in width.

With its divided, grey-green leaves this native of dry coastal Californian scrubland is hardy and will die down in winter, and although slow to get established, it’s vigorous once it’s happy.

An excellent specimen plant for a sunny mixed border, Romneya is fully deserving of its coveted RHS Award of Garden Merit, and you can be sure that this is a proven garden performer - you can therefore plant this in the garden with confidence, for stunning displays for many years to come.

Supplied as an established plant in a 9cm pot, ready to plant out. Growing to a height of 2.5m & width of 1.5m.

Top Tips
Californian Tree Poppies dislike transplanting but once established can spread, so choose your planting position carefully
Care Information

Planting Advice for your Romneya coulteri (Californian Tree Poppy):

  • Best in full sun in fertile, well-drained soil against a warm, sunny wall protected from cold winds.
  • 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 once 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 then refill the hole with the earth removed (backfilling).
  • Firm in the soil with your heel, avoiding the root ball and water well.
  • Mulch around the base of the plant with a collar, compost, gravel, bark etc.

Aftercare advice for Californian Tree Poppy:

  • Keep plants well-watered while they establish.
  • Use plant supports later in the flowering season.
  • Provide a deep, dry mulch in the winter months for protection. 

Pruning Advice for Romneya Californian Tree Poppy:

  • Cut back flower stems close to the base in March.
Delivery Information

Most orders are sent on a fully-tracked courier service with Yodel. To avoid perishable items being stuck at depots and deteriorating, no signature is required, and our courier is asked to leave your order in a safe place on your property.

We'll send a tracking link when we dispatch your order, so you know when its due to arrive. Please note, once delivered we cannot be held responsible for loss or theft from your property. If you have any specific delivery instructions, please let us know - there's an option to enter a short message for the courier at the checkout.

Smaller, lighter, single-item orders may be sent through the post with Royal Mail - in which case no tracking is available.

Our experienced nursery team will always send your plants nursery fresh in the perfect condition to thrive when you plant them, so although most plants are very tough and will not be affected by all but the most extreme frosts or heatwaves, we avoid dispatching the most perishable plants if extreme weather is forecast, or over Bank Holiday weekends.

Please note, we cannot guarantee delivery on a certain day or time. Delivery to outlying postcode areas may take 1-2 days longer, dependent on your location.
