There are an estimated 391,000 plants on the planet earth, more than you could see or memorize in a lifetime. Many of these have rich histories of study and classification, with scientists, botanists, and green-fingered people around the world spending their lives researching and growing them.

  1. Primrose
  2. Prickly Pear Cactus
  3. Parsley
  4. Poppy
  5. Prairie Willow
  6. Pansy
  7. Petunia

With many plants come many names – so we’ve decided to make a list of different plants that start with the letter ‘P’. We’ve also included a short FAQ section to answer some of your most common questions.

Primrose 

This is probably one of the most popular and well-known plants that start with the letter P. Its Latin name is ‘Primula Vulgaris’ – named so because they are some of the first to appear once spring arrives. It is native to many parts of the world, including Europe, northwest Africa, and parts of Asia. 

It’s worth noting that there are different varieties of primrose, including the evening primrose, round-headed Himalayan Primrose, Drumstick Primrose, and many more. Though many of them look different, the main thing that distinguishes them from other plants is the time in which they flower, and the bright color of their flowers. 

Primroses are an easy to care for, a gorgeous addition to your home and garden. 

Prickly Pear Cactus

Prickly pear cactus scientific name

For the next plant on our list, we’re taking you to the desert. The prickly pear cactus is an alien and unique plant that is native to the Americas but has been introduced to other areas of the world since humans first discovered them. Its Latin name is Optunia, named after the Ancient Greek city ‘Opus.’ 

There are hundreds of different species of Optunia, but the most common features are thick green pads with detachable spines and bright colored, rounded flowers which can be pink, orange, or yellow.

Texas prickly pear cactus

Like most desert plants, Prickly Pear Cacti have adapted to live and flourish within the harshest and driest of conditions – the desert areas of Texas are ideal. They have shallow roots which allow them to absorb rainfall more easily, as well as sections of their pad that store water.

If you have the climate for it, Prickly Pear Cacti are a great addition to your front or back garden, or as a cool addition to a landscaping project. 

Parsley 

Parsley, sometimes known as ‘garden parsley,’ is a species of plant that is most often found in the Mediterranean, though it has long been cultivated in wider parts of Europe. It is an extremely common herb used in cuisine all over the world.

There are different kinds of parsley, though the one you’re most likely to be familiar with is Curley leaf parsley because of how easy it is to grow, as well as its distinctive taste. 

Parsley is a light green, flat-leafed plant with long thin stalks that shoot upwards. The easiest way to distinguish parsley leaves from other plants checking to see the shape of their leaves – parsley leaves have sharp, pointed leaves, whilst other similar plants might be rounded. 

Parsley uses

It would be impossible to list all of the different dishes that parsley is used as an ingredient in here, but it is commonly added to sauces, salsas, pestos, and soups. It is a light herb without an overbearing taste, so it is often added to create a small flavor without fear of ruining a dish.

Parsley is a great plant to grow if you’re looking for something that looks pretty but can also be used to cook with. 

Poppy

Poppy juice can be addictive and poisonous
Can I grow poppies in my yard? Opium poppies are illegal, but you can grow Oriental poppy (Papaver orientale).

Poppies are probably best known for their symbolism after the first world war. In 1914, certain fields that had once been the place of terrible battles were repopulated by flowers – the poppy. Since then it has been transformed into a symbol for the fallen after the first world war, included in poems, and used in memorials even to this day. 

Are poppies poisonous?

The poppy is also known as the source of the drug opium, which has been used for centuries as a pain killer and used to create drugs such as morphine and heroin. 

Despite these two very specific and different associations, the poppy is a great addition to your garden because of its strange shape and gorgeous bright red color. Although red is sometimes thought of as the only color that poppies can be, there are several variations of color including orange, yellow, and white. 

Prairie Willow

Prairie willow is a shrub that is known for its emerald green coloring and spikey shape. Shrubs are strong plants that are adapted to grow in volatile environments. It is also known by its Latin name ‘Salix Humilis’ and it is native to certain parts of the United States and Canada. 

Though it’s a much rarer plant than some of the others on this list, it’s worth considering as an addition to your garden because of its gorgeous color and low requirements. Prairie Willows grow well at half-sunlight. 

Pansy

Another beautiful and well-known flower is the Pansy. Pansies are created by the hybridization (crossing different types of flowers) of different species native to Europe and western Asia. Their name ‘pansy’ comes from the french word for ‘thought.’

Typically, pansies are identified by their flowers with large ‘faces’ – which are heart-shaped petals. They vary massively in color, with modern horticulturists developing a multitude of different colors like orange, purple, red, white, yellow, and gold. 

Do pansies like sun or shade?

Pansies grow best with 5-6 hours of daily sunlight, but if they are exposed to full sunlight during the hottest parts of the day, they can be damaged and slow the flowering process.

Do pansies last all year?

If you’re considering planting pansies, it’s important to know that their flowers can last for up to seven or eight months of being kept in the correct conditions. In cool climates, pansies tend to flower from spring to summer, but in hot climates, they can bloom in fall and winter. 

Petunia

Petunia scientific name: petunia
Do petunias need sun or shade? More sun is better, if you want many blooms.

This is the last of the most famous flowers beginning with ‘P’ on this list, but it wouldn’t be complete without the Petunia. The Petunia is another staple in gardens around the world, recognizable for its star-shaped petals and strikingly bright colors.

Types of petunias

When we write ‘Petunia’ we’re not referring to a single flower, but a genus (family) of over 20 species of different flowering plants. This family is of South American origin, adapted to hot temperatures and difficult conditions. 

Most Petunia flowers you’re likely to see in a garden are hybrids, as through the years these flowers have been cultivated and changed to have specific characteristics. Although the most common Petunia colors are red, white, and purple, there are unique variations. Petunia flowers are an important addition to any flower display and have been used for centuries as such.

FAQ

Do Primroses Come Back Every Year?

If primroses are cultivated properly, they are more than likely to come back each year. They are most likely to flower from December through to May, though most commonly in the spring.

Primroses are repeat bloomers, which means providing the conditions are right, they are likely to come back each year. If you would like to ensure that your primroses come back at the same time every year, then you will need to plant them where there is good light. 

Is It Illegal To Grow Red Poppies?

This can vary depending on the country, but in the USA it is illegal to grow Papaver Somnuferum (the species most commonly known as red poppy). This is because unripe seed pods can contain a substance that when dried and cultivated can become opium. That’s not to say that different varieties of poppy can’t be grown legally.

There are many different kinds of poppy with different colors so it can be easy to find one if you’re looking to plant something. Popular types of poppy that you can legally grow include Papaver Orientale, Eschscholzia, and Papver Nudicaule

How Long Do Petunia Flowers Last? 

Petunia flowers generally last between 2 and 3 years. How long they last mostly depends on climate and planting conditions. They are normally annual plants in places that have cold winters because they are not adapted for low temperatures.

In cold climates, petunias are most likely to flower during the summer and will stay until the earliest frosts of autumn. In warmer climates, petunias can last all year round providing they get the correct sunlight and care.
