Understanding Calendula Officinalis

Pot marigold or Calendula Officinalis stands out as an attractive plant, with bright yellow or orange flowers, offering numerous health benefits.

Several varieties of calendula exist for planting, each possessing distinct characteristics. 'Pacific Beauty Mix' is known for blossoming in multiple shades of orange, whereas 'Alpha' attracts with large, vibrant flowers. Uniquely, 'Pink Surprise' flaunts an unusual pink color.

Historical Uses

Throughout history, Calendula officinalis has been used therapeutically in many cultures. This striking flower, known for its bright orange-yellow petals, has an extensive legacy of medicinal applications across various cultures and centuries.

It was highly esteemed in ancient Egypt for its rejuvenating properties. Meanwhile, in medieval Europe, skin diseases, digestive complaints, and fever were often treated with this herb. Not only valued for its medicinal uses, Calendula also held high cultural significance. In religious and ceremonial events, particularly in Christianity, Calendula flowers were often utilized in festivals honoring the Virgin Mary.

Due to its robustness and ease of cultivation, it became a staple in apothecary gardens. From there, folk medicine and domestic remedies incorporated the plant. Widespread topical application on wounds and skin irritations was common, and ingestion via teas or soups for internal ailments was also prevalent.

Health Benefits

This vibrant flower, aside from being aesthetically pleasing, contains potent medicinal properties contributing to overall wellness.

Its benefits include anti-inflammatory properties. Skin irritation, wounds, or digestive inflammation can be soothed by using or consuming calendula. Traditionally, this flower has been useful in healing wounds along with treating skin infections and rashes, owing to its antiseptic properties.

Calendula also supports oral health thanks to its antibacterial properties. Fighting against gingivitis and plaque build-up becomes easier with calendula, making it a helpful supplement to oral hygiene routines.

Immune system stimulation is another attribute of calendula, which increases the body's resistance against infections. Its antioxidant properties play a crucial role in preventing chronic diseases, which contributes to longevity.

It also helps relieve gastrointestinal disorders by soothing the stomach lining and reducing discomfort from ulcers or gastritis.

Preparing The Soil

Slightly acidic to neutral in pH (approximately between 6.0 to 7.2), suits Calendula best.

To enhance fertility, enrich the soil by adding organic matter such as compost or well-aged manure. This not only supplies nutrients but also helps maintain soil structure, promoting plant growth. Organic amendments also improve the water-holding capacity of soil, addressing the hydration needs of plants.

Planting and Growing Calendula

After preparing the soil, growing it comes next. You can sow these plant seeds directly into the soil or start them in indoor pots. Plant them 1/4" deep with a distance of approximately 6" between each seed. Under favourable conditions, expect germination within two weeks. Full sun to partial shade is their preferred light condition.

Watering techniques play a crucial role in the growth of these plants. Moist but not overly saturated soil is ideal, as excess water can cause root rot. During dry periods, deep watering once a week is recommended.

It grows in about 50-60 days. With correct watering techniques and efficient pest control, you can enjoy the vibrant, sun-like blooms of this plant throughout the growing season.
