Indigofera spicata

Forssk.

Fabaceae


Indigofera hendecaphylla and Indigofera spicata Forssk., used to be considered as the same species and were then united under Indigofera spicata. They are now considered to be different species. The literature is therefore confusing, and references to toxicity most probably refer to Indigofera hendecaphylla[

The plant is harvested from the wild for local use as a medicine and source of materials. Indigo, of which this species is a minor source, has a very long history of use as a dye. Because of its fascinating deep blue colour, its great colour fastness to light and the wide range of colours obtained by combining it with other natural dyes, it has been called 'the king of dyes' and no other dye plants have had such a prominent place in as many civilizations as this genus. This species was at one time cultivated for this purpose but, with the advent of synthetic dyes, demand for the plant dropped dramatically[

Known Hazards

Reports of toxicity for this species are often confused with the closely related Indigofera hendecaphylla. It is likely that Indigofera hendecaphylla is the more toxic of the two, but this is not clear. Below are the reports on toxicity for the two species.
Some strains of this species have leaves and seeds that are highly hepatotoxic[

The leaves of Indigofera hendecaphylla, possibly only of tetraploid forms originally from Sri Lanka, contain per 100 g dry matter 0.1 - 0.5 g indospicine (2,7-diamino-7-amino-heptanoic acid) while the seeds contain 0.1 - 2 g. Indospicine is a specific antagonist of arginine, interfering with its synthesis and incorporation into proteins and with the synthesis of DNA. Indospicine is highly toxic to chicken, rabbits, pigs, goats, sheep, cattle and horses. In small doses it causes loss of vitality and abortion in cattle and goats. Indospicine is especially dangerous to horses, which relish plants containing it and eat them preferentially[

Propagation

Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[

Cuttings of about 20cm long are planted in situ at a spacing of 60 cm x 60 cm with 5 cuttings per hole. Plants produced from cuttings usually remain very low and cover rarely exceeds 12cm in height. A fair cover can be established in 4 - 6 months and a continuous, even cover in a year from planting[
