Romneya species are half hardy perennials that range from 90 cm to 1.8 m in height.
They have a woody nature, and bloom with flowers reminiscent of poppies in the summer and early autumn.
Some of the common names for Romneya include Matilija poppy and California Tree poppy.

Matilija poppy and other Romneya plants prefer to grow in warm climates. The poppy seeds should be sown at a depth of 6 mm following the last spring frost. They like to grow in sunny areas and likes an average dry soil.
If starting off indoors then sow seeds in peat pots about two months before the last spring frost is expected. They should take about a month to germinate at 12 to 15 degrees centigrade.
Once growing, transfer the poppies outdoors at a spacing of 60 to 90 cm (smaller species) to 1.5 M apart (larger varieties).
Once growing it takes a bit of work to look after Romneya plants. They are very easy to grow but difficult to control. It is necessary to prune at the roots to stop Romneya members from spreading. If you require more plants then propagate from the root suckers.
