Brugmansia sanguinea
Scarlet angel's trumpet, scarlet datura (Datura sanguinea)
It is an open, evergreen shrub or tree with bright green, wavy-margined leaves and long, tubular, orange-red, yellow-veined flowers from late spring to autumn
This plant is native to regions of subtropical South America, commonly grown in gardens. They occasionally escape, probably in plant clippings, as they are not thought to produce seeds in NZ.
The alkaloids hyoscyamine, hyoscine and atropine are found in all parts of the plant, especially the seeds.
Cattle, sheep, horses, buffalo, goats, pigs
Reddening of the skin (human), dilatation of the pupils, nausea, drowsiness, agitation, rapid and irregular heartbeat, hallucinations (human), highly abnormal behaviour. In horses, polydipsia, polyuria, and diarrhoea have been noted, while impaired vision and intermittent muscle spasms have been noted in ponies.
Convulsions, coma, and death
Haemorrhages of liver, kidney, and heart; congested blood vessels in the lungs; presence of plant material in stomach
History
Symptomatic care; anticholinesterases in serious cases
Good if leaves/flowers are ingested, as these have an extremely bitter taste that would deter further ingestion; seeds are highly toxic with poor prognosis.
Plant removal from paddocks
