They are a good choice for someone who does n’t have a quite a little of clock time to prune and maintain flush . They are stunning consider in their natural habitat .
Adaptation to the Desert Climate
Desert plant are able to endure blistering , ironical environments because they have adapt over time . big leafage have give path to few leaves , or spines . A bombastic surface area on a leaf permit more water to evaporate from the works . With few leave of absence , photosynthesis must occur in the radical . Many stanch hold pee and some cactus variety will " splosh " if gently rocked , due to the water they hold .
Many plants utilise spines for defense because they are very tardily - maturate . With few or no leave-taking , the photosynthesis process is much slower . Waxy finishing and hair help insulate the industrial plant and make H2O loss slow . The hairsbreadth enfold the plant in a microlayer of humid air .
Large underground tooth root systems can spread for large distance or develop directly down to access ground water if it is usable . Many desert plants can inject toxic chemicals into the soil to obliterate their competitors ' roots . Sturdy , extensive ascendant systems permit desert plant to maximize the available pelting water .
Cactus
Cactus are probably the first desert plant life that come to mind . There are more than 2,000 varieties of cactus , and they change greatly in size and shape . Some , like saguaro , grow 40 feet or taller . Many , but not all , have backbone . flower cactus are especially attractive against the stark , barren landscape of a tropic desert .
Holiday cactus , of which the Christmas cactus is in all likelihood most intimate , are unusual in that they do not produce on the ground in thier natural setting . Instead , they grow in the genitalia of larger trees in semitropic rain forest .
Wildflowers

Until 1952 , this chemical substance was used as a cardiac stimulant . Never pick or handle any part of a desert wildflower unless you are well - versed in plant identification .
Trees & Shrubs
The Joshua tree is one of the well - known desert tree diagram . This member of the yucca family grow only in the Mojave Desert . Joshua Tree grow in dry soil on slope and plains and often constitute orchard . Shrubs and trees in tropical comeuppance are evergreen and drouth resistant . Creosote bush and sage brush are sturdy shrub that grow in abundance .
Grasses
Perhaps the easily - known symbol of the Old West is the Russian tumbleweed . This grass , which looks like a assemblage of dead limbs , can become as big as a Volkswagen . Many multitude are surprised to study that new tumbleweeds produce bantam blooms . As Amaranthus graecizans roll , they disperse seeds – a typical plant has around 250,000 . In many areas , this is consider a weed and address with herbicide .
