Romneya coulteri
(Californian Tree Poppy, Matilija Poppies)

Romneya coulteri is a wonderful, choice perennial, that is tough to get going from our point of view here on the nursery as it can be a bit fussy in the propagation stage.
 
Once established, as our pot plants are, it grows strongly and vigorously and produces a lovely mass of silver grey-green foliage which is delicate and attractive just on its on with divided, lobed leaves and glaucous stems which creates a mass of foliage with a really quite attractive colour.
 
In mid summer large, tissue paper like, crinkled petals appear creating wonderful, large, pure white flowers with a yellow center that has a feint, sweet fragrance. The flowers are produced on mass through summer, these flowers resemble poppy flowers and are huge, sometimes being as large as 20cm across.

William Robinson - "The fairest plant that ever came to our land from that country of flowers, California."
 
Graham Stuart Thomas "The huge white poppies, with a great mass of dark yellow stamens, are silky and crinkled, gracious and lovely."
 
A really choice plant to add to the garden that will work best in full sun, prefers a drier soil rather than moist or wet and will tolerate a poorer soil too, can grow to a height of 1.5m with a spread of 1.5m after a few years.
 
When you receive your plant and get ready to plant it DO NOT break the the root up and tease out the roots, this plant does not like root disturbance and it will find its own way once planted, there is no need to tease the root ball. They are tricky to divide so take care if you attempt this once established.
