Calendula officinalis aka Calendula

Taxonomy

Calendula officinalis, also known as the pot marigold, common marigold, ruddles, Mary's gold, or Scotch marigold, is a flowering plant in the daisy family Asteraceae. Its exact origin is uncertain, as it has a long history of cultivation and may have originated from southern Europe or be of garden origin. This hardy annual variety produces bi-colour blooms ranging from gold to pale orange, which contrast beautifully against its dark green foliage. While it is often grown as an annual flower, Calendula officinalis is a short-lived perennial in warmer climates. It is not to be confused with the common marigold (Tagetes spp.), but both belong to the Asteracea family and share a daisy-like appearance. The plant's Latin specific epithet, officinalis, refers to its medicinal and herbal uses. The name "pot marigold" originates from the gold flowers traditionally used in cooking during the festivals of the Virgin Mary, combining the names "Mary" and "gold" to form "marigold."

How to care for Calendula

Difficulty

If you're looking for a plant that offers a moderate level of challenge, Calendula is a great choice to test your gardening skills.

Water

Calendula should be watered regularly, allowing the soil to dry out between waterings.

Soil

Calendula loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Calendula requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Garden Marigold is always in the right place to thrive.
