Orchis coriophora is a BULB growing to 0.3 m (1ft). It is hardy to zone (UK) 5. It is in flower from April to June. The species is hermaphrodite (has both male and female organs) and is pollinated by Flies, beetles. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers moist soil.
Although many mealybugs may crawl down the stalk of an orchid to feed near the roots, soil dwelling mealybugs are usually members of the genus Rhizoecus. These tiny, segmented insects are covered in a white, waxy coating and may lack eyes, depending on the species.
Generally temperatures between 50° and 80° F (10° to 27° C) are ideal for orchids; but occasional brief periods of temperatures above 100 F (38 C) or drops even into the 30s (0 C) will not harm most orchids as long as no frost forms on the leaves. Cold injury includes damage from temperatures above and below freezing.
