There is only one member of the Hacquetia genus and it is a hardy perennial with the scientific name of Hacquetia epipactis.
It grows from about 5 to 10 cm (2 to 4 inches) in height, making it ideal for use in the rock garden.
Hacquetia flowers at the death of winter through the beginning of spring.
It carries a yellow flower, and unusually, this will appear before the leaves do.

Hacquetia seeds should be sown fresh in the autumn on the soil surface. They can grow in both shady and sunny areas of the garden, and prefer soil that is moist yet has good drainage.
You can start to grow Hacquetia plants indoors first, but this requires a little work. The seeds should be imbibed in moist soil, put in a black bin bag and refrigerated for 3 weeks. The seeds should then be sown in flats and kept at about 13 degrees Centigrade. Germination can take anything from one to six months.
Once you have grown some Hacquetia plants they can be put into the garden before the last frost of spring at a spacing of about 25 cm.
