Abstract:
Some of the most unusual and fascinating plants in the plant kingdom include cacti and succulents.
Cacti can have opulent forms, spines, and occasionally fragrant huge decorative flowers.
Succulents have the ability to grow in attractive shapes and bear fragrant flowers on long-lasting inflorescences.
In addition to their potential as aesthetic plants, cacti and succulents are frequently drought, heat, and/or cold hardy and can have low nutritional needs.
When combined, cacti and succulents form a collection of plants that have the potential to be used as decorative potted, bedding, or landscape plants.
Three years ago, we started a project to assess the potential of understudied species from these two plant families as novel attractive crops.
Early research centered on figuring out what triggers flowering and evaluating each species’ potential as a new decorative potted, bedding, and/or landscape plant.
Over 75 cactus species from six genera have had their flowering needs established thus far.
With succulents, we have concentrated on figuring out how to make already recognized aesthetic crops flower (typically because of plant/leaf morphology). In addition to flower induction research, we created standards for evaluating each plant group’s beauty potential.
Additional testing was done to create production protocols, and the results will be discussed.
This study is an illustration of a case study that shows what experiments might be taken into account before starting work on a new group of species that have the potential to be commercialized as ornaments.
The most promising species, upcoming tests, breeding requirements, and planned collections will all be covered.
Cacti are what kind of plants?
Cacti are a good option if you want to give your plant collection a bit more variety. Fearful of jagged spines? Not to worry. Some varieties of cactus plants are completely spineless. Additionally, a lot of cacti have interesting characteristics like white hairs, yellow flowers, or wacky shapes. Cacti grow slowly and require little upkeep, which is even better. Cactus plants don’t require a lot of repotting, pruning, feeding, or watering.
Cactus plants are frequently confused with other succulents. Cacti are succulents with chlorophyll-containing woody or herbaceous stalks. The fleshy stems serve as a water reservoir and a photosynthesising organ for the plant. Cactus plants, in contrast to other succulents, have areoles on the outside of the stems that resemble cushions. Cacti typically have spines. The modified leaves that make up cactus spines shield the plant from predation by animals and provide shade for the plant’s surface.
If given the relatively straightforward care instructions they require, cacti make excellent landscape specimens and indoor plants. This calls for soil that drains effectively, low to moderate moisture, full sun outside or brilliant inside light, and desert cactus plants. The requirements of jungle cacti are slightly different, and they do well under lower light levels. We go over everything mentioned above next! Discover which of these 13 varieties of cactus plants would be the greatest fit for your house by reading on.
What distinguishes cacti from other decorative plants?
Opuntias (subfamily Opuntioideae) and “cactoids,” two groupings of “core cacti,” make up the majority of the 1,500–1,800 species of cacti (subfamily Cactoideae). The majority of these two groups’ members are unmistakably cactus. They have squishy succulent stems, which are important photosynthesis-producing organs. They lack, have tiny, or have temporary leaves. They produce blooms with ovaries that are submerged deeply into a fleshy receptacle under the sepals and petals (the part of the stem from which the flower parts grow). All cacti feature areoles, which are short, highly specialized branches with incredibly short internodes that produce blooms, spines, and regular shoots. [10]
Only two groupings of cacti remain: the relatively smaller Maihuenia and the three tree-like taxa Leuenbergeria, Pereskia, and Rhodocactus (all originally included in Pereskia). Since these two groups differ significantly from other cacti[10], they must frequently be excluded from general descriptions of cacti. The species of the first three genera resemble other tropical forest trees on the surface. When fully grown, they feature long-lasting leaves that serve as the primary source of photosynthesis, along with woody stems that may be covered in bark. Their blooms may have areoles that produce additional leaves and superior ovaries, which are located above the sites where the sepals and petals attach. The two varieties of Maihuenia have pronounced succulent leaves and succulent stems but not photosynthetic ones. [10]
Growth habit
Cacti have a wide range of development behaviors that are challenging to categorize into distinct, straightforward groups.
Cacti can resemble trees (are arborescent), which means they usually have a single, more-or-less woody trunk that is topped by a number of branches. The branches of the genera Leuenbergeria, Pereskia, and Rhodocactus are covered in leaves, making it difficult to identify the species of these genera as cacti. As with Pachycereus pringlei or the larger opuntias, most other cacti have branches that are more like regular cacti, devoid of leaves and bark and coated in spines. Some cacti, like larger specimens of Echinocactus platyacanthus, can grow to be tree-sized without having any branches. When many stems emerge from the ground or from branches that are very low to the ground, as in the case of Stenocereus thurberi, a cactus is often referred to as being shrubby. [11]
Columnar is a good word to describe smaller cacti. They are made up of upright, cylinder-shaped stems that may or may not branch, with no obvious distinction between the trunk and branches. It is challenging to draw a line between columnar forms and forms that resemble trees or shrubs. For instance, Cephalocereus senilis has smaller, younger specimens that appear columnar, and older, larger specimens may resemble trees. The “columns” might occasionally be horizontal rather than vertical. Stenocereus eruca can therefore be characterized as columnar while having stems that grow parallel to the ground and root at regular intervals. [11]
Cacti with even smaller stems could be referred as as globular (or globose). Unlike columnar cactus, they have stems that are shorter and more formed like balls. Globular cacti can grow alone, like Ferocactus latispinus, or their stems can group together to form enormous mounds. A cluster’s stems may all or some of them share a root. [11]
Other cacti look very distinct from one another. Some plants develop as forest climbers and epiphytes in tropical areas. Their stems often lack spines and are flattened, resembling practically leaves in form. Large climbing cactus are common; one Hylocereus specimen measured 100 meters (330 feet) from root to farthest stem. When growing in trees high above the ground, epiphytic cacti like the Rhipsalis or Schlumbergera species frequently hang downward and group together in dense groups. [11]
Is a succulent a decorative plant?
Succulent plants, sometimes referred to as succulents in botany, are plants having thickened, fleshy, and engorged portions that typically serve to retain water in arid regions or soil conditions. Due to the fact that it frequently can only be used as an accurate characteristic at the single species level, it is a feature that is not used scientifically for the definition of the majority of plant families and genera. The Latin word sucus, which means “liquid” or “sap,” is where the word succulent originates. [1] Water can be stored by succulent plants in a variety of parts, including the leaves and stems. Some succulent organs can contain up to 9095 percent water. [2] Since roots are sometimes included in definitions, geophytes that endure adverse conditions by dying back to underground storage organs may be referred to as succulents. The term “succulent” is occasionally employed in horticultural contexts in a way that excludes species that botanists would classify as succulents, such as cacti. Because of their eye-catching and distinctive appearance, as well as their propensity to flourish with only a small amount of care, succulents are frequently grown as ornamental plants.
There are several succulent species found within many plant groups (more than 25 plant families).
[3] The majority of species are succulents in some families, including Aizoaceae, Cactaceae, and Crassulaceae. These water-preserving plants frequently live in deserts and other hot, dry climates as their homes. Succulents are well-suited to surviving in an ecosystem with restricted water sources because they can grow well on scarce water sources like mist and dew.
A cactus is it a shrub or a tree?
The cactus species are part of a family that includes over 127 plant genera and over 1700 different species of cacti. The moon cactus is an example of a species of these cacti that can also sprout flowers or that already have blooms on their tops.
Cacti aren’t actually trees, even though they have stems that resemble trees. It is obvious that cactus plants are different from trees since their stems are flexible rather than woody. A cactus cannot be regarded as a tree because the smaller cacti are also rather little and lack even a fraction of a tree’s height. Succulent plants include cacti. There are several succulents, including cacti. The simple method to tell if something is a cactus is to look at its spines. Although cacti can produce flowers, this does not qualify them as blooming plants. There are more than a thousand different species of cactus, and each one is unique from the others. However, a plant can only be called a cactus plant if it possesses a precise set of characteristics. A succulent’s skin surface is different if it contains a stem, which can store water, making it impossible for these plants to lose water. The plant’s spines are another factor in the argument over whether it is a cactus. Although certain cacti are also referred to as flowering plants, their physical characteristics differ from those of other cacti.
Do cacti grow indoors?
Despite being recognized for their love of sunlight, many cacti grow well as houseplants. For some unusual decor, place one on your windowsill or in your living area. The ideal houseplant, indoor cacti typically require less light and are smaller in stature.
Bunny Ears Cactus (Opuntia microdasys)
The bunny ears cactus gets its name from its look and is native to Mexico. Its two pads are designed like bunny ears. They should be handled carefully since they have glochids or brown prickles on them. The bunny ears cactus is the ideal indoor plant because it may reach heights of two to three feet. If given enough light, it will blossom with white flowers and bear purple fruits in the summer.
Chin Cactus (Gymnocalycium)
Gymnocalycium is a kind of cactus native to South America and is frequently referred to as the “chin cactus.” Greek for “naked kalyx,” its name alludes to the flower buds’ lack of hair or spines. Some chin cactus like shade, while others do better in sunlight, depending on the kind.
Saguaro Cactus (Carnegiea gigantea)
Although it grows slowly, the Saguaro cactus can reach a height of forty feet. This indicates that you can use it as an indoor plant for a number of years before relocating it outside. It has the traditional cactus appearance thanks to its barrel-shaped body. This plant, which is a native of the Sonoran Desert, needs a lot of sunshine. Place the plant in direct sunlight if it is being maintained indoors.
Old Lady Cactus (Mammillaria hahniana)
The mammillaria family, which comprises 250 species, includes the old lady cactus as a subspecies of pincushion cactus. It is renowned for its halo of small pink or purple flowers that bloom in the spring and possesses hairs and spines. A sandy potting mix should be used to plant the old lady cactus, and it should receive water every other week.
Star Cactus (Astrophytum asteria)
The star cactus, also known as sea urchin or sand dollar cactus, can be recognized by its circular body that is divided into eight slices. It has small white spots and white hairs all over it. It produces a yellow blossom in the spring. The star cactus is the perfect indoor plant because its diameter only reaches two to six inches.
Easter Cactus (Hatiora gaertneri)
Easter cactus, a native of Brazil, blooms in late winter or early spring. White, orange, and lavender are just a few of its bloom colors. The plant has a distinctive shape because of the way its spines are piled on top of one another.
Christmas Cactus (Schlumbergera bridgesii)
The Christmas cactus, which is frequently mistaken for the Thanksgiving cactus, blooms in the dead of winter. It boasts vivid red blossoms and is frequently given as a Christmas gift. The Christmas cactus thrives in average indoor settings. Don’t overwater plants because it will make their roots rot. Although this plant can thrive in low light conditions, its blossoms benefit from additional light.
Moon Cactus (Gymnocalycium mihanovichii)
The moon cactus, also referred to as the chin cactus, varies in size, shape, and color. The hibotan cactus is a well-known cultivar. Its South American origins can be traced to its vivid red, pink, yellow, and orange hues. On window sills that receive some light, these little plants flourish.
A cactus is a plant, not a flower.
Numerous kinds of blooming plants with succulent (water-storing) stems belong to the family Cactaceae. Cacti are unique among all other plants due to the existence of an organ called the areole. Flowers, new branches, and spines emerge from areoles. Spines come in a variety of shapes and sizes; some are delicate and feathery to shield the plant from harsh sunlight, while others are strong and spiky to provide protection. The spines on cacti restrict animals from getting to their water supply, even though they may be one of the few sources of water in arid areas. Cacti have a waxy covering called a cuticle that serves as a barrier against water loss. They also use stomata, which open at night instead of during the day like other plants do, to conserve water. The plant’s stomata are tiny pores that allow carbon dioxide to enter for photosynthesis.
The size of cacti varies according on the species. Blossfeldia liliputana, a South American plant with a mature diameter of less than an inch (2.5 centimeters), may be the smallest cacti species. The Mexican enormous cardon, which is almost 60 feet tall, is the tallest cactus (18 meters).
The majority of cacti genera originated in the Americas and can be found from Canada to Chile. They are now widespread around the world, particularly in Australia, South Africa, and nations in the Mediterranean.
Some people mistakenly believe that cacti are only found in the desert, yet many species, like the prickly pear cactus, may be found in a variety of settings.
Cacti are seed-producing blooming plants. They are able to bloom every year, but when it rains a lot, they will produce a lot of flowers. Different flowers have different looks and smells to draw different pollinators, like insects and bats. Cacti grow slowly and have a long lifespan. Saguaro cacti, for instance, can survive for up to 175 years. Between the ages of 75 and 100, they do not develop their first arms.
Populations of cacti are generally stable. However, some species are diminishing as a result of being taken out of the wild and planted on xeriscaped lawns as decorative plants (landscaped areas that require little or no irrigation).
Most cacti have root systems that stretch out near the ground to absorb as much precipitation as they can. Some species can survive several years of drought because they are adept at storing water.
