Calendula (Calendula officinalis), also known as Pot Marigold, is a great plant for many gardens.
Whether you are an experienced gardener, or a true beginner, calendula are easy to grow. In fact, they are great low-maintenance plants – that quite frankly thrive on neglect.
As we will discuss in this article, there are a great many reasons to grow them. They not only cheer up your outside spaces with their sunny color.
They also have a range of practical uses in your garden, in your kitchen and around your home.
How To Grow Calendula
Calendula are perennial, though in most areas where they are grown are treated as annual or biennial plants. They will not generally survive hard frosts.
They form bold heads of vivid orange flowers that are daisy-like in form on fast-growing plants of bushy habit.
Gardeners sometimes sow calendula seeds indoors a few weeks before the last frost date in their area (though grow lights may be required).
You can then plant them out once the weather warms.
Alternatively, you can direct sow them in the garden after all risk of frost has passed in spring. In warmer climes, seeds can also be direct sown in fall for winter colour.
It is also popular, however, to choose to buy calendula as bedding plants.
You can then place these bedding plants to grow on in containers or in-ground growing areas.
Once you have some calendula in your garden, it will tend to self-seed readily if grown in the right conditions. This means that if calendula is provided with the appropriate environment, it will generally persist there for years with little effort from the gardener.
Though not usually truly perennial, therefore, it can sometimes find a home in a perennial polyculture growing area.
Where to Place Calendula
Calendula is generally considered as an ornamental plant, and placed in a flower bed or border, or in containers.
But it can also find a role in other parts of the garden – for example, as a companion plant to fruits or vegetables, or on the sunny fringes of a forest garden.
Though it is a stalwart of the typical informal, cottage-style garden, it can also fit in with a range of other garden design styles.
Calendula will do best in a sunny or lightly shaded position.
It will do well in any well-drained soil, though a good loam is ideal. But it will tolerate a range of different soil types and a pH anywhere between 4.5 and 8.3.
Interestingly, these plants will actually flower most prolifically when grown in a low-nutrient setting, with lower soil fertility.
Caring for Calendula
When grown in a suitable location, calendula will require little care. The plants will bloom from June right through to November and sometimes even beyond in certain areas.
Deadhead your calendula regularly (perhaps also harvesting some calendula flowers). You should then be treated to blooms over a long period.
Pinch out growing tips to keep the plants bushy and prevent the formation of too much straggly growth.
Take care not to over-water and avoid fertilizers or other measures that will add too many nutrients to the soil around your plants.
Remember, when caring for calendula, that less is more.
10 Reasons To Grow Calendula in Your Garden
There are a great many reasons to begin growing calendula in your garden. You’ll find ten of the top reasons to grow these useful and attractive flowers below:
1. To Attract Beneficial Wildlife
Calendula are well known as an excellent plant for a wildlife garden. Their vibrant flowers attract bees, other pollinators, and a wide range of other insects.
Since they bloom for such a long time, they provide as consistent source of nectar and pollen throughout a big chunk of the year.
In addition to attracting pollinators, calendula also serves as a food source for a number of lepidoptera species, and so will draw moths and butterflies to your garden.
By helping to increase biodiversity, growing calendula can make it easier for you to garden organically. Growing this useful plant can aid in creating a thriving and resilient garden ecosystem.
2. As a Companion Plant For Your Fruits and Veggies
Of course, attracting beneficial wildlife is not only good for the garden ecosystem as a whole, but the wildlife itself.
By bringing in beneficial wildlife, calendula is also a great companion plant.
It helps the fruits and vegetables you grow by attracting pollinators. It also helps by attracting predatory insects like ladybugs, lacewings and hoverflies that help keep pest numbers down.
What is more, these plants also repel whitefly from tomatoes, and act as a trap crop to lure aphids away from other crops.
What is more, calendula can also aid other plants when used as a living mulch or cover crop. It has thick, fibrous roots and grows in thick patches and so can cover and protect the soil.
It can be used either between other crops or during gaps in crop rotation.
3. For a Long-Lasting Display of Blooms
One of the goals in an ornamental garden is year round visual interest.
Since calendula blooms over such a long period of time, it can be a great plant to help you meet this goal. The bright and cheerful flowers can really brighten up the garden over the summer and fall.
The long flowering period is not just good for the wildlife which enjoys the garden. It is great for human inhabitants too.
4. To Speed Up Composting
Interestingly, calendula can be used as part of a herbal mix which acts as a compost activator.
The Quick return composting system was introduced by Maye E. Bruce in 1935. It involves using six common herbs in honey as a compost activator.
The six herbs commonly used are nettle, dandelion, chamomile, yarrow, valerian and oak bark. However, calendula is often suggested as an alternative for use in a compost activator.
Compost activators speed up the composting process and make it easier and quicker to return nutrients to the garden system.
5. For Cut Flower Displays
You don’t just have to enjoy calendula flowers in your garden. You can also cut the blooms and use them in fresh flower displays inside your home.
In India, calendula flowers are sacred and are used to decorate the statues of Hindu deities for hundreds of years.
But whatever your religious persuasion, the flowers can be hugely decorative, and can be used for numerous floral arrangements – in vases or garlanded, or in a range of other ways.
They are great for bringing warm, sunny tones into your home.
6. For Herbal Medicine
Calendula also have a long history of use in herbal medicine. The plant has a range of beneficial properties.
It is anti-inflammatory and antiseptic, which can be used to soothe and heal skin, and cleanses and detoxifies when taken internally.
You can use the flowers fresh or dried in a wide range of herbal preparations and domestic remedies.
7. To Make a Natural Dye
The flowers can also be boiled to make a natural yellow dye. The dye can have culinary applications, as an alternative to saffron for coloring food.
It was traditionally used to add color to butters and cheeses.
The dye can also add golden tints to hair, and can also be used, alone or with the addition of a mordant to set the dye, to color natural fabrics.
8. To Help Determine What Weather is To Come
When you spend a lot of time in the garden, it can be useful to observe natural signs.
A number of plants can give cues that suggest a weather change is on the way. Calendula is one of those plants.
Interestingly, the blooms will often close up in humid conditions, and in certain areas, can give an indication that wet weather could be coming.
Taken along with other observations, this can help gardeners to predict what weather is on its way.
9. To Use in Your Kitchen
Calendula is not only used to color food but also to impart flavor. The leaves are rich in vitamins and minerals, similar to the dandelion, and can be eaten raw.
Most commonly, however, the petals are the part of the plant that is used for culinary purposes. They are used fresh, or dried.
When dried, they have a more concentrated flavor. A few examples of the culinary uses of this flower can be found in the recipes section, below.
10. To Make Cleaning and Cosmetic Products
Perhaps the most useful thing about calendula from a human perspective is the plants potential as an ingredient for cleaning and cosmetic products.
