Taxonomy

The generic epithet commemorates Gaspar Melchor de Jovellanos.[6]

This species is believed to have diverged from its New Zealand counterparts approximately 4.1Mya. It then diverged from Jovellana punctata about 1.0Mya.[7]

Etymology

The name "violacea" means "violet" which is referring to the violet-coloured flowers of this species.[8]

Description

This species is a semi-evergreen, upright shrub with oval, lobed leaves that occur on red stems.[4][5]

It can reach heights between 1.5 – 2.5m and 0.5 – 1m across.[4]

This plant produces pale violet, bell-shaped flowers with dark purple spots. This species flowers in summer.[4][8]

Cultivation

This plant can be propagated with cuttings in summer.[4]

It should be grown in loamy, well-drained, soil while under full, direct sunlight. It can be grown in both slightly acidic or alkaline soils. During the winter, it should be sheltered because even though this species is somewhat hardy, it is not tolerant of below-freezing temperatures.[4][5][8]

It is also said to grow well in conjunction with Jovellana punctata.[5]

It has gained the Award of Garden Merit (AGM) by the Royal Horticultural Society.[9]

Uses

This plant is mainly used for ornamental purposes.[9]

Distribution

This species is native to the Biobío region of Chile. It is also found in New Zealand.[9][7]
