No matter you’re a gardener who is looking forward to learning the names of plants and flowers or you just want to teach your kids about the different types of plants on the planet, this list is definitely for both. Without further ado, let’s take a look at the names of plants that start with the letter O.
Oak Mistletoe (Phoradendron Leucarpum)
Mistletoe grows in more than 1,000 different species all over the world. They are all broadleaf evergreen parasite plants. They grow in loose, twiggy balls and adhere to the branches of other trees and shrubs using a root-like structure that is named a haustorium that takes nutrients and moisture from the host plant. If you don’t require mistletoe for a joyous Christmas harvest, you shouldn’t grow it. The mistletoe balls often have an offensive appearance rather than being decorative, and their development patterns may be detrimental, occasionally dying or severely disfiguring trees.
Finding berries from an established plant and carefully rubbing them into the bark of a suitable tree in late fall or early winter is the ideal method for planting mistletoe. Numerous species of mistletoe have a gradual growth and it can also take some time to mature.
Oakleaf Hydrangea (Hydrangea Quercifolia)
A flowering deciduous shrub known as an oakleaf hydrangea (Hydrangea quercifolia) has huge clusters of blooms on robust branches and unusual leaves with lobes resembling those of an oak tree (the Latin word for “oakleaf” is “quercifolia”). The long-lasting flower panicles of this shrub, which start out white and progressively become purplish pink, are highly sought after. This multi-stemmed shrub, which typically grows 4 to 8 feet tall, sucker spreads and has an erect, rounded growth style.
Oakleaf hydrangea grows well as a specimen plant, as a foundation plant, in mass plantings in shrub borders, and in open forest gardens. These plants’ large leaves give them a rough roughness that contrasts with plants with finer features.
The leathery leaves of the fall foliage turn a beautiful shade of purple, orange-bronze, or even scarlet red. These exfoliating branches even provide winter texture and color.
October Glory Maple (Acer Rubrum October Glory)
The red maple tree, a cultivar, is a native of North America, and October Glory is one of its cultivars. It is grown primarily for its stunning reddish-orange to scarlet fall leaves. However, it makes a striking specimen plant for all three seasons of the year thanks to its dense, spherical canopy and glossy, green leaves in the spring and summer. Due to its pollution tolerance, this medium-sized shade tree is a superb option for full to partial sun urban street growth. A low-maintenance plant, this cold-hardy tree also adapts to a wide range of soils, including nutrient-poor soils.
October Glory maple can handle some shade, but it will probably have better fall color if it is grown in full sunlight. However, when you move further south in its range, it will be beneficial due to the afternoon shade.
Okra (Abelmoschus Esculentus)
For its tasty seed pods, okra is grown. In landscapes, it is also grown annually for its lovely blossoms.
In its native dry tropical climates, the okra plant is a perennial plant with an erect, branching growth style. Okra grows large; the adult plant can be between 6 and 8 feet tall. The flowers have reddish centers and are typically yellow or white. The elongated seed pods that develop after the flowers bloom are collected as the okra fruit. The up to 7-inch-long seed pods are filled with white seeds that form a pentagonal-shaped chambered structure. The seed pods can be used in a variety of ways in the kitchen; their sticky mucilage makes them particularly beneficial for thickening soups.
Old Man (Artemisia Abrotanum)
The Artemisia genus has thousands of species. And one of the oldest and most extensively grown is the fern-like southernwood (Artemisia abrotanum). This herbaceous perennial forms a tiny, bushy mound with upright branches that resembles a shrub. Its foliage ranges from gray-green to green and has a nice, lemony, camphor-like scent. Historically used as an air freshener, southernwood is now frequently utilized as a powerful all-natural insect repellent. In addition, it is frequently grown in orchards to ward off ants and fruit tree insects. Small and not particularly decorative, its blooms are. Southernwood grows quickly and does best when planted in the spring.
Countries That Start With The Letter PSouthernwood is a popular addition to herb gardens and containers and makes a wonderful choice for growing as a low hedge or border. It requires virtually little upkeep and may flourish in arid, infertile soils where other plants struggle to survive.
Oleander (Nerium Oleander)
Nerium oleander, sometimes known as oleander, is a tiny, single- or multi-trunked tree that naturally develops as a mounded and round shrub. When planted in groups or borders, the oleander plant’s dense, leathery, dark green foliage serves as a privacy screen. Pink blooms are typically delicately formed, showy, and fragrant, while some kinds also produce orange, red, yellow, or white flowers. The 1- to 3-inch flowers have a particularly long blooming season and are visible from spring to summer, as well as occasionally in early fall and all year round in warmer locations.
Look for an oleander bush that is one to two years old with a sturdy, straight center stem when you are out shopping. They grow quickly and have thick many stems, making them ideal for a living screen or hedge.
One Seed Juniper (Juniperus Monosperma)
You will be surrounded by dark shrubby conifers as you move through the parched mountainous terrain of the Southwest United States. Little shade is provided by the greyish-brown bark on their trunks during the intense heat. You most likely discovered Juniperus monosperma, also known as the one-seed juniper. You can’t see it, because the majority of the plant is underground. The surface growth of this juniper tree is slow, but when it reaches maturity, its taproot shoots down up to 200 feet.

Onion (Allium Cepa)
Allium cepa, a biennial bulb, is related to garlic (Allium sativum), shallots (Allium ascalonicum), and chives (Allium schoenoprasum). As they grow from a bulb, which is essentially a modified leaf structure with multiple layers, onions feature hollow, tubular, blue-green leaves. From the bulb’s base, a thin network of roots protrudes; as the plant grows, the bulb may partially emerge above ground.
Onions grow moderately quickly and should be planted in the spring. They can be grown from seeds, transplants (seedlings that have recently sprouted), or sets (tiny onion bulbs that are about to start growing in their second and final year). Because of their chemical composition, onions are poisonous to pets, so be cautious.
When the earth thaws and the temperature is still over 28 degrees Fahrenheit in the spring, plant onions. The optimum locations include neutral pH, loose soil, and ample sunshine. To give the developing plants the freedom to spread, space onion rows at least 1 foot apart and leave at least 6 inches between each plant.
