Geraniums are the foundation of the summer garden and offer continuous colour in beds or containers from late April until fall. These low-maintenance sun-lovers are actually members of the Pelargonium family (genuine geraniums are a separate group of perennial plants), and they come in an almost infinite variety of colours, shapes, and sizes. Here are some things to check for at your neighbourhood garden centre.
Zonal geraniums are probably already something you’re familiar with. The name “zonal” comes from the dark, zone-like patterns of bronze, purple, or dark green that are present on the surface of the leaves and that become darker as the foliage matures. Zonal geraniums are the most popular kind. The upright-standing zonal geraniums are available in a range of hues, including white, red, crimson, burgundy, peach, salmon, and bi-color. The hardy, sturdy plants known as zonal geraniums prefer a little bit of dryness. Your plants may suffer in hot, humid weather. You must remove the flower heads as they wilt in order to preserve them in prime condition.
Avoid buying zonal geraniums with yellow foliage or any that have lost their lower leaves, according to purchasing advice.
Variegated geraniums are prized for both their vividly coloured leaves and their vibrant flowers, and they look beautiful in containers both by themselves and when combined with other annual bloomers. Variegated forms of zonal geranium have an upright structure and can reach heights of two to three feet. Even when they are not in bloom, these plants are gorgeous. The majority have tricolour or bicolor leaves. The following are some traditional variegated options to look for:
Shopping advice: Look for short, stocky plants when buying variegated geraniums. Avoid plants that are tall and lanky or that have a lot of crinkly, dried-out leaves at the base of the plant. Don’t be concerned if you don’t see as many blooms on the plants in the store or in your yard because most variegated-leaf geraniums don’t bloom as lavishly as their cousins.
It might be challenging for a novice gardener to distinguish between a zonal and seed geranium. In spite of the fact that they resemble each other quite a bit, seed geraniums can usually be distinguished by their method of sale. Although seed geraniums are typically sold in bigger groups or flats and are less expensive than zonal geraniums, zonal geraniums are typically sold in individual pots. Heavy bloomers, seed geraniums are the best choice if you want to cover a whole bed or landscaping with plants. These low-maintenance annuals produce single flowers in a variety of hues and are often shorter and more compact than zonals.
Shopping advice: Look for stocky plants with brilliant green leaves when buying seed geraniums. Severely desiccated plants with shrivelled leaves and stems should be avoided.
For hanging baskets, window boxes, or tall, vertical pots where the plants’ attractive foliage can trail over the edge like a waterfall of blooms, ivy geraniums are unbeatable. The term “ivy geranium” refers to the plant’s trailing habit and ivy-like leaves. Ivy geraniums grow swiftly once they are established and can spread several feet in any direction. Ivy geraniums come in a variety of sizes; smaller, denser versions are sometimes referred to as balcony geraniums. Red, pink, white, salmon, burgundy, lavender, and bi-color are among the available hues. Remove the flowers when they wilt and feed your plants every few weeks with an all-purpose liquid fertiliser to keep them blooming consistently.
Ivy geranium shopping advice: Look for compact, thick plants with lots of bloom buds.
Don’t be intimidated by this geranium group’s intimidating moniker. The offspring of upright zonal geraniums crossed with several types of common ivy are simply known as interspecific hybrid geraniums. The outcome is a plant with the best qualities of both parents: continuous flowering, a dense mounded or somewhat trailing habit, and resistance to heat and drought. The interspecific geranium species Calliope and Caliente are both well-known.
Shopping advice: When looking for these gorgeous plants, seek for foliage that is lush and dark and that is crowned with showy flowers in hues like red, coral, pink, lavender, and orange.
To experience a scented geranium leaf’s strong fragrance, just lightly brush or rub it. There is a wide variety of smells and leaf forms available in scented geraniums. Lemon, lime, rose, orange, mint, and cedar are among the common fragrances of geraniums. Sadly, the claims that one type, “Cintronella,” may keep mosquitoes away are unfounded. Throughout the summer, scented geraniums produce tiny pink or white flowers.
Shopping advice: Before making a purchase of fragrant geraniums, read the plant label. Choose plants that will match your space because some species stay small and compact while others can reach heights and widths of 3 feet. Additionally, before buying, massage the leaves to make sure you like the aroma.
Because Martha Washington geraniums’ jewel-like blossoms are so eye-catching, you may frequently find the plants in florist stores in addition to your neighbourhood garden centre. These elegant plants, sometimes known as regal geraniums, produce a canopy of flowers that are bi-colored pink, lavender, white, and burgundy. The Martha Washington kinds of geranium prefer colder, wetter climes rather than bright, sunny weather. It might be challenging to get the plants to bloom again once the initial batch of blossoms fade. Although they make wonderful gifts, their performance in the garden may not last long.
Shopping advice: When buying Martha Washington geraniums, consider plants that are just beginning to bloom and look for vibrant green leaves. Steer clear of plants with blossoms that are already fading.
Height/Spread:
Depending on the type, they range from 5 to 8 inches in height for dwarf cultivars to 2 to 4 feet tall and wide for ivy varieties.
Exposure:
Most plants thrive in full sun. While zonals can handle moderate shade, regal types do prefer some partial shade. Some afternoon protection should be offered in excessively hot areas.
Bloom time:
Geraniums are prized for having a lengthy blooming period that can extend into the fall and begins in the spring. Plants may also bloom in the winter or the early spring if temperatures are kept above 45 to 50 degrees.
Color:

- Avoid watering from above. Fungal illnesses will become less likely as a result.
- They may tolerate slight frosts in cool temperate regions. After each flowering cycle, lightly trim the plant to promote further blooms.
- When flowering is finished in the fall, harder pruning (one to two thirds of the plant) can be done.

Pelargonium with Ivy Leaf Pelargonium with trailing growth, fragrant, ivy-shaped leaves, and tiny blooms. Excellent for use as a ground cover in hot, dry locations and in containers.
Aromatic Geraniums More so than their blooms, scented geraniums are grown for their leaves. Their leaves have a tiny furrow at the edge, which sets them apart from regular Geranium varieties and gives them a ruffled appearance. To release the oils and make a pleasant perfumed area in the garden, crush the leaves. Rose (P. graveolens), Apple (P. ordoratissimum), Peppermint (P. tomentosum), and even Lemon are among the many diverse smells and variations that can be found (P. citronellum). Some of them are even edible, so read the labels carefully before eating.
Pelargonium Zonal (P. hororum) This cultivar not only features attractive blooms, but also unusually shaped leaves. These set themselves apart from the other kinds by having zones or leaf outlines. These zones produce a distinctive feature plant for the garden or pots and can be simple (just two colour forms) or complicated (three or more colour forms).
