Euphorbia polychroma (Cushion Spurge) by Patrick Standish.
Spurge can be grown straight outdoors by sowing the seeds at a depth of 3 mm after the last frost of spring.
They should be sown in either a sunny or partially shaded part of the garden, they prefer a poor soil (ph 6 to 7) that can be moist.
If you prefer to start perennial Euphorbia plant species indoors first then they should be prepared about 7 or 8 weeks before they are due to be put in the garden following the last frost of spring.
The seeds should be pretreated by placing in a refrigerator for one week, then imbibing in warm water for about two hours.
The Spurge seeds should then be planted into peat pots. It will take about two to four weeks for the spurge seeds to germinate at 18 to 20 degrees centigrade.
Once the Euphorbia is growing, more plants can be had by taking cuttings once flowering has occurred or through collecting more seed. Perennial Euphorbia plants should be watered regular while it is growing.
