Lion's ear (wild dagga)
Leonotis leonurus
Leonotis leonurus, the lion's ear or wild dagga, is a fast-growing, soft-woody evergreen shrub in the mint family (Lamiaceae) native to South Africa, reaching about 4.9 to 9.8 feet tall with square stems carrying tiered whorls of brilliant orange, tubular two-lipped flowers. In the garden it works as a striking late-season focal shrub or large border plant for hot, dry, full-sun positions and pairs naturally with other South African and Mediterranean-climate planting. It is frost-tender - RHS rates it H2, meaning it tolerates cool conditions down to about 34 to 41°F but is killed by hard freezes - so outside roughly USDA zone 9b–11 it is grown in containers, as a cut-back tender perennial, or under glass. Note that the dried leaves are mildly psychoactive (containing leonurine and labdane diterpenes) and the plant is regulated in some countries, and high-dose animal studies have shown organ toxicity, so it should not be treated as a food or casually ingested. It can also naturalize and become weedy in frost-free Mediterranean climates such as parts of California, Hawaii and Australia.

In its native South African range the orange tubular flowers are primarily bird-pollinated - sunbirds (white-bellied, black, olive, collared and others) are drawn to the curved tubes - with honeybees and butterflies as secondary visitors.
