The pendulous flower clusters of the South African native greentip Natal lily (Clivia nobilis) glow bright orange. Each stalk bears an umbel of 20 to 60 flowers that fade to pale green tips. When grown from seed, this species takes at least 6 years or more to flower, but each plant can live many decades.

Clivia nobilis was named in 1928 in honor of the Duchess of Northumberland, whose family name was Clive and whose garden at Syon House, just across the river from Kew, was famous at that time.
