Blue heliotrope identification
Blue heliotrope is a perennial herb typically growing to about 60 cm in height. The plant has a large, well-developed root system. The leaves are lanceolate (tapering to a point) in shape, and can grow to 2–9 cm in length and 0.4–2.5 cm wide. They are a dull-green colour and are covered in short hairs.
Blue heliotrope has flowers that are arranged in a caterpillar-like formation, featuring 0–7 branches depending on the size of the plant. The flowers themselves sit in two parallel rows along small branches, with petals 5.5–8 mm in length. The flowers are purple to blue in colour, and can be found on the plant for most of the year, apart from in winter in more southern areas.
