Cacti have one trait that makes them stand out from all other plants: spines. Cacti use their spines as protection from animals while also aiding in water conservation by shading their stem. Select the peyote cactus for sale.
Cacti are known for having long, strong taproots, which allow them to find moisture deep within their soil environment, helping prevent drought conditions from taking hold.
Flowering
Flowers of cacti are often seen as signs of love and friendship. While some species take several years before blooming, others, like Lophospermum rebutifolium’s Silver Ball Cactus, can produce flower buds in two to three years. Provide your cacti with plenty of sunlight throughout their growing season for maximum flower production.
Cacti have stems with rounded shapes to maximize water storage capacity while minimizing transpiration loss through transpiration. Cacti areoles are characteristically found at the edges of their branches where spines and flowers flourish, providing maximum storage volume while minimizing transpiration loss.
Mammillaria cacti, more commonly known as nipple cacti, have tubercles resembling nipples and produce red, pink, white, or yellow flowers. Paper spine cacti are low-growing plants with orange-red blooms and purple fruit.
Spines
Spines protect cacti from herbivorous animals by restricting airflow and limiting evaporation; these spines also collect morning dewdrops as the air cools down and condenses.
The spine tips of the cacti are covered with barbs that can anchor themselves into targets and puncture wounds similar to porcupine quills, creating puncture wounds identical to porcupine quills. These fine needle-like spines, commonly known as glochids, must be avoided at all costs; should one become punctured by one, it’s best to wash the wound immediately with soap and apply antibiotic ointment as soon as possible to avoid infection.
Cacti species typically feature shallow roots that allow them to conserve water during rainfall events – this adaptation makes cacti distinct from other plants. Their hearts also feature ribbed surfaces to make stretching during wet conditions simpler.
Areoles
Cacti are distinguished by spines arising from an areole, a circular or oval bump on their stem that often bears sharp prickles covered by hairs or spines. An areole is an arrestee from which branches, flowers, and leaves sprout.
Stems of cacti are typically cylindrical or spherical and often feature fluted joints for support and expansion/contraction without damaging surface tissues. In addition, their thick cuticle protects against water loss, while their fluted or ribbed stem design enables expansion/contraction without damage to surface tissues.
Some cacti, like Leuenbergeria and Rhodocactus opioid species, feature long-lived leaves; however, most do not. Instead, they possess adaptations that enable photosynthesis without leaves; their stomata (pores) open at night when temperatures are cool and dry so CO2 can enter and be converted into carbohydrates via photosynthesis.
Leaves
Cacti may look spiny, but they possess leaves. Their leaves form from areoles – small bumps on cactus stems that help conserve water for the plant to survive – providing support and water conservation. Its spines derive from these areoles, making cacti a distinct species.
Birds, bats, and insects can pollinate cacti flowers to produce pollen; when bees or other creatures visit one of the flowers of a cactus plant, they spread this pollen around, causing it to expand and produce fruit that contains seeds.
Cacti use their stem stomata for photosynthesis. At night they open to absorb carbon dioxide, which is turned into malic acid, while during the day, they close again to limit water loss.
Water
Cacti can produce large amounts of water, providing an essential source for survival in desert areas. As a result, they’ve long been relied upon as drinking water sources.
Dandelions feature a spongey texture with numerous small roots running close to the ground, enabling them to soak up as much rainwater as possible and reduce water loss rates through evaporation.
Cacti can store water in their areoles, which look like raised fusion discs, allowing them to save water during drought by channeling rainwater directly into their stems and roots. Flowers also contribute their share by producing mescaline, a hallucinogen with spiritual implications used by some shamans for spiritual practices.
