The European heliotrope (Heliotropium europaeum) belongs to Boraginaceae (the Borage family). It is an annual herb that is native to Europe, Asia, and North Africa, but it is widely naturalized elsewhere, such as in Australia and North America. This herb grows on roadside and it can reach 40-60 cm in height. The leaves are ovate, gray-green, and covered with soft hairs. The white, yellow-throated flowers bloom in two rows on either side of the cyme, throughout year but mainly summer and fall. The fruit is a bumpy nutlet. This plant contains pyrrolizidine alkaloids and is poisonous.
