About
Dudleya ingens is a species of perennial succulent plant in the family Crassulaceae commonly known as the rock liveforever or Baja liveforever. A relatively large member of the genus Dudleya, this species has long green succulent leaves, and in April to June is characterized by pale yellow to white pink-tinged flowers topping tall, reddish inflorescences. It has a stem clothed densely with old, leathery leaves, and the inflorescence may be nodding, with the floral branches bearing the flowers tending to unfurl like the fronds of a fern. It is similar in appearance to Dudleya brittonii, but differs in range and chromosome number. This species is endemic to the state of Baja California in Mexico, being found from Santo Tomás to the southern coast of the state.
How to grow it
This species finds suitable use as a rock or container garden plant. It grows well in full sun with well-drained soil and very infrequent summer irrigation. It is cold hardy to 25 °F (−4 °C) and is drought tolerant. The leaves are evergreen, and in spring to early summer the red stems bearing pale yellow to white flowers appear. Leaves may be green or covered with red spots.
Where it grows
Dudleya ingens occurs mostly along the coast and foothills of northwestern Baja California, from the vicinity of Santo Tomás and San Vicente south to Puerto Faro San José. It occurs from the coastal plain to as far inland as the western slope of the Sierra de San Pedro Martir, with the inland form taking on a markedly different appearance, but intermediate plants found between. Plants may vary from locality to locality, near Punta Colonet approaching the appearance of Dudleya brittonii.
