The only problem with Bidenâs history lesson is that the âman with steel in his spineâ he referred to should have been George W. Bush, not Barack Obama. Lest we forget, it was Bush rather than Obama who initiated the government rescue of the auto companies.
* The Pilosocereus cactus is native to Brazil and can grow up to 20ft in height. * The giant Saguaro cactus is the world's tallest, growing up to 67ft high, weighing six tonnes and can live for 250 years. I takes 50 years to produce its first flower.
Many cacti have roots that spread out widely, but only penetrate a short distance into the soil. In one case, a young saguaro only 12 cm (4.7 in) tall had a root system with a diameter of 2 m (7 ft), but no more than 10 cm (4 in) deep. Cacti can also form new roots quickly when rain falls after a drought.ereskia (which is close to the ancestral species from which all cacti evolved) does have long-lasting leaves, which are, however, thickened and succulent in many species. Other species of cactus with long-lasting leaves, such as the opuntioid Pereskiopsis, also have succulent leaves.
