'Snow on the Mountain' or 'Mountain Snow' or 'Ghost Weed' (yoo-FOR-bee-uh: mar-jen-AY-tuh) Euphorbiaceae:
Ornamental green and white flowering bracts produced in mid to late summer and fall. This species in an upright growing annual, growing from 2 to 4 feet tall. Nice for cutting material, but some people are sensitive to the sap, the sap is an eye irritant and often is transferred from the hands to the eyes, so wash hands after handling any broken parts of the plant that are leaking sap. A good, long lasting cut flower - if the cut ends are seared or dipped in boiling water. Grow in full sun to partial shade, in a well-draining soil; though tolerant of some wet conditions. Best look in nitrogen poor soils, rich soil produce lush foliage that tends to flop and less flowering. Can be grown in large pots too. Needs three months of growth and long days for best color display.
Plants do not like root disturbance, so it’s best to sow the seeds in place of growth or use deep plugs.
Native to Minnesota to Colorado and Texas. Sow outdoors in situ. Germination in less than two weeks at 68-78ºF, but sometimes can be prolonged over many weeks. Seeds have a hard seed coat, might be helpful to drop the seeds in a cup of hot water and allow to soak for 12 hours before sowing.
