Dogbane

Plectranthus caninus

Dogbane is a perennial herb from the mint family, which grows to about 15cm high, 30cm when in flower. When crushed, leaves have a very strong aroma, however dogs and cats are said to be able to smell the aroma from intact leaves and be repelled from the plant. This herb is also know as “scaredy cat plant”. This plant prefers full sun to part shade, but may need more shade in very hot areas. If there is too much shade the plant becomes “leggy” with less foliage. It’s frost tender so it needs a warm protected position to protect it from frost and hot sun, it’s not suited to open conditions. Water young plants regularly, and once established older plants will tolerate short dry periods. It flowers in spring and summer. And this plant is also recommended for use as an insect repellent.
