Similar to its close relative - the Madder of the Continent (botanical name, Rubia tinctorum), the yellow bedstraw too yields a red dye. Although this plant is cultivated with a view to obtain the dye from its roots, the venture is not very profitable, as the roots of this clambering plant are very small.

However, the dye obtained from the yellow bedstraw roots was used in the Hebrides or the Western Islands to tint woollen materials red. It was found that the roots of the plant did not yield an equal percentage of dye as the Madder and, hence, people never cultivated yellow bedstraw very extensively. In fact, under common conditions, the crops were found to be very small to yield profits.

The conditions necessary for cultivating yellow bedstraw are similar to those needed to grow Madder. In order to thrive well, this plant requires a deep, light and rich loamy soil. In addition, it is necessary to trench the land properly and manure it before planting the herb.

Yellow bedstraw propagates by means of its running roots. Alternately, the plant can also be propagated by its seeds, a method sometimes used to cultivate Madder.

Apart from the yellow bedstraw, many other species of the genus Galium also have roots that have the aptitude to yield red or yellow dye, but none of these species have been practically tried so far. This is primarily owing to the fact that their yield is very small for successful commercial cultivation as dye yielding plants.
