This is the UK native Common Spotted which grows in neutral to alkaline soils which are often damp. Can be grow in grassland, the garden or a pot. It is the dactylorhiza most likely to self seed in a garden provided the conditions are right. It is a good beginners orchid as it will usually bulk up fairly quickly.
The price for all the dactylorhizas is for ONE mature tuber that should flower next year.
Tubers are normally sent out when the plant is dormant. In this case usually between OCTOBER and MARCH.
