(November 2016) Pogona is a genus of reptiles containing eight lizard species, which are often known by the common name bearded dragons. The name bearded dragon refers to the beard of the lizard, the underside of the throat which turns black if they are stressed or see a potential rival.
Desert willow (Chilopsis linearis), with its delicate, pale green leaves and large, fragrant flowers, loses its leaves in winter. A North American native, desert willow grows wild in the southwestern United States and Mexico. It commonly grows in desert areas that flood seasonally, like stream beds and low canyon areas.
Oaks regenerate from acorns and stump sprouts. They do not produce many seeds compared to other tree species. Acorns decompose quickly if they become wet. White, swamp white and bur oak acorns begin to develop in the fall after they drop from the tree. Northern red, black and northern pin oak acorns begin to develop during the spring after they drop from the tree. Oaks can survive in low light when they first begin to grow, but they need more sunlight as they grow larger.
