About Linaria aeruginea
Linaria aeruginea, commonly known as 'Roadside toadflax', is a charming annual or short-lived perennial native to the Mediterranean region. It displays small, two-lipped flowers in shades ranging from yellow to purple, often with darker veins and a distinctive spur. Its compact habit and abundant flowering make it ideal for rock gardens, sunny borders, or as a filler plant in naturalistic garden settings.
Native range

Care tips
It thrives in full sun for optimal flowering. Moderate watering is required, allowing the soil to dry out slightly between waterings, and it tolerates dry periods once established. The substrate should be well-drained, preferably sandy or stony. A common mistake is overwatering, which can lead to root rot.
