The 280 species of pelargoniums have asymmetrical blooms with seven stamens. The genera Pelargonium and Monsonia (Sarcocaulon), which have both summer and winter growers, are home to some of the best succulent and caudiciform plants. There are 15 stamens in Monsonia blooms.
The largest species of Geranium, this one has purple woody stems that support an umbrella of glossy green, finely divided leaves that measures 3 feet in diameter. The plant typically dies (goes monocarpic) after flowering every two years, but in damp areas, the huge head of pink flowers with wine-dark centers may appear sooner. The hairs on flower stalks are sticky.
the Madeira Islands’ native species. Needs a Winter that is primarily frost-free, although in their second year, they could be utilized as summer bedding. There is a white cultivar in use.
L’Hritier, Pelargonium, 1789 Name: Pelargos is a Greek word that means “stork” and refers to seed pods that look like storks’ bills.
a sizable genus with 280 species, the bulk of which are indigenous to South Africa. They are common, low-maintenance flowering plants that can be collected by caudiciform plant enthusiasts. They range from non-succulent herbs to shrubby plants with fleshy leaves, stems, and roots or tubers. A few species have spines that protect their stems. Many species have hairy leaves and stems.
The majority of the time, leaves are alternating, palmately lobed or pinnate, and frequently have lengthy petioles. Zones of light or dark patterning may be visible on the leaf surface. The majority of colors are present among the numerous species of the asymmetrical five-petalled blooms.
Although the horticultural commerce mostly concentrates on non-succulent cultivars with a small genetic background representing only a few of the wild species, pelargoniums are significant decorative plants. Numerous hybrids and cultivars are offered in a variety of hues, including white, pink, red, purple, maroon, and variegated petals. Although found in many species, such as P. gibbosum, yellow(ish) flowers represent a more recent development in horticultural cultivars.
Many Pelargonium species, particularly P. graveolens, generate fragrant oils with a variety of flavors, including rose, mint, citrus, apple, and nutmeg. The rose-scented varieties are the most significant in terms of commerce. P. graveolens is extensively grown for its essential oils, which are used to make perfumes.
Succulent A free-draining compost that should be allowed to dry out in between waterings should be used to pot up pelargoniums. Pelargoniums can be multiplied by taking stem cuttings; these cuttings should be made immediately below a leaf joint because this is where the new roots will develop.
Bowker’s pelargonium Harvey 1862 named for Henry Bowker, a soldier and naturalist who collected the plant in the 19th century.
a geophytic succulent plant that develops from a sizable underground tuber and has a mass of pinnate feathery leaves. A group of pale yellow-green blooms held tight to the leaves make up the inflorescence.

1767 Monsonia Linneaeus (Bushman Candles) named after: Lady Anne Monson, Charles II’s great-granddaughter
a collection of upright, woody sub-shrubs with waxy bark, spines, and some degree of stem or root succulence. Sarcocaulon, a previous caudiciform genus, has been included into Monsonia. Some former Sarcocaulons get their popular name because of their waxy bark and resinous exudates, which make them combustible even when the stems are green.
Monsonias require strong sunlight and regular watering to survive because they are native to hot, dry climates. When in active growth, Caudiciform Monsonias should receive very little water, or just a light misting every now and then to prevent dehydration.
Monsonia with spiny stems, North Escarpment, and Nieuwoudtville, RSA. Small pink blossoms on this stem succulent can just be made out in the image. Herbivores in this dry environment are put off by the vicious spines.
The geranium is what kind of plant?
Any of the about 300 species of perennial herbs or shrubs of the family Geraniaceae, which are primarily indigenous to subtropical southern Africa, are geraniums (genus Geranium), also known as cranesbills. The most popular plants for greenhouses and bedding are geraniums. Around 280 species of annual, biennial, and perennial herbaceous plants known as geraniums belong to the closely related genus Pelargonium.
The Pelargonium genus contains cultivated geraniums that range in texture from herbaceous to woody, with thick fleshy leaves that can be spherical, lobed, or deeply cut. The terminal clusters of flowers range in color from white through pinkish hues to deep crimson and violet. Hybrids make up the majority of cultivated species. There are options for ragged or frilled petals, varied colors, and double blooms. Geraniums can also be grown from seed, though they are typically propagated via stem cuttings, from which flowering plants can be generated in four to five months. A line of seed geraniums that are useful for bedding because of their uniform symmetry, lengthened flower stalks, and propensity for quick and tidy flower petal shedding has been developed through breeding and selection.
Can geraniums be grown indoors?
Pelargonium species, which come in pots, make great indoor plants that may be grown all year round. They normally become available in March through June, and if given enough light inside the house, they will bloom continuously. There are several fresh varieties, like vining and hanging basket cultivars. They are available in many different types of containers and at varying stages of development.
Are geraniums sun or shade lovers?
Wish your life had a little more carefree beauty? Plant some geraniums, maybe. Geraniums are beautiful and low-maintenance plants that belong in planters, planting beds, and perennial borders.
Geraniums can be divided into two major groups. Zonal, fancy-leaf, ivy, perfumed, and Martha Washington (or regal) varieties of annual geraniums (Pelargonium species), which often only live for a year, are some examples. Perennial geraniums (Geranium species), which bloom continually from spring to summer, combine striking foliage with attractive blooms that emerge intermittently or continuously.
Where to Plant Geraniums
You must be aware of the type of geraniums you have in order to select the ideal planting location. With the exception of the ivy geranium, which thrives in mild shade, most annual geraniums require a location in full sun. On the other hand, depending on the variety, perennial geraniums can grow in either sunlight or shade. In the country’s southern and western regions, both types profit from shielding from the sun during the warmest time of the day.
What Kind of Soil to Use for Geraniums
Geraniums grow best in healthy, well-draining soil, which is ideal for both perennial and annual geraniums. Improve soil drainage and quality when growing geraniums in planting beds by adding 3 inches of Miracle-Gro Garden Soil for Flowers to the top 6 to 8 inches of native soil. When growing geraniums in pots, Miracle-Gro Potting Mix should be used because it is light and fluffy. For the ideal planting medium, combine garden soil and potting soil in equal portions, or fill raised beds with Miracle-Gro Raised Bed Soil.
How to Plant Geraniums
Starting with young plants, such as the premium geraniums from the Miracle-Gro Brilliant Blooms collection*, is ideal (and simplest). Geraniums, both annual and perennial, benefit from warmth, so postpone planting in the spring until all risk of frost has passed. Once the summer heat subsides in the fall, you can also plant perennial geraniums. Try planting perennial geraniums from late fall to early spring in areas with mild winters.
Geraniums range in height from 4 to 48 inches tall and 6 to 36 inches wide, depending on the variety. For information on the recommended spacing for your type of geranium, consult plant tags. Use a pot that is at least 10 inches across for annual geraniums or at least 12 inches across for perennial geraniums when planting geraniums in pots.
Geraniums should be watered thoroughly after planting, giving the root ball and surrounding soil time to absorb the water.
How to Water Geraniums
Check the soil once a week for annual geraniums, and water when the top inch is dry. During their initial growth season, keep newly planted perennial geraniums in continuously moist soil. With the exception of periods of extreme drought, perennial geraniums can typically thrive on rainfall after they are established.
How to Mulch Geraniums
After planting geraniums, cover the area with a 2- to 3-inch layer of mulch to help keep the soil moist and to prevent weed growth and sun exposure. Use Scotts bagged mulch, chopped leaves, pine straw, or another material that is easily obtainable in your area.
How to Feed Geraniums
Your plants receive an excellent starting dosage of nutrients when you start with rich, nutrient-rich soil. However, you should also feed them frequently all season long for maximum results. Apply Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food to your geraniums a month after planting to give them the extra boost of nutrition they require for magnificent blooms. Make sure you adhere to label directions.
How to Grow Perennial Geraniums
Even in the coldest climates, perennial geraniums don’t require particular care to survive the winter. After the initial flower flush, cutting perennial geraniums back by around one-third can encourage more blooms. Cut stems back as necessary if hardy geraniums like “Rozanne” or “Pink Penny” spread out too quickly and widely. These vining geraniums can have up to two-thirds of their length removed, and the plants will still grow back. To encourage new growth and prevent wilted leaves, prune cranesbill geraniums to 2 to 4 inches height after flowering.
How to Use Geraniums
Annual geraniums are excellent at stealing the show in planters and flowerbeds. Regal geraniums can resist cool weather and form lovely hanging basket plants, making them an obvious choice for planting in the early spring. Ivy geraniums are very stunning. Geraniums with aromatic leaves are strong in containers and form a lovely patio display where the leaves may be stroked and enjoyed.
In gardens with some shade, perennial geraniums add much-needed color and can thrive next to mature trees. While mid-size perennial geraniums go well with lanky shrubs, shorter perennial kinds create beautiful ground covers.
