Thorow-wax, Hacquetia: Cultivation & Garden Use

The Hacquetia genus consists of a single member, Hacquetia epipactis, which is commonly known as Thorow-wax, though it's often simply referred to as Hacquetia. Do not confuse with Sanicula epipactis, the Sanicle or Wood Sanicle.

It grows from about 5 to 10 cm (2 to 4 inches) in height, making it ideal for use in the rock garden.

How to Grow Hacquetia Plants in the Garden

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 (55°F). Germination can take anything from one to six months.

Once you have grown some Hacquetia plant seedlings, they can be put out into the garden before the last frost of spring. Use a a spacing of about 25 cm (10 inches).

Caring for Hacquetia

If you require more Hacquetia plants, then they can be divided in the spring time.

Spring is also a good time to supply mulch to the Hacquetia plant to help keep the roots cool in the summer.
