Calendula

Calendulas give a splash of sunshine in the garden and as cut flowers they bring some sunshine into the house.

Calendula officinalis indicates by the second part of it’s name (officinalis) that it is also a very important herb. Nowadays, pot marigold, garden marigold, English Marigold and Scotch Marigold are most commonly known as Calendula which helps to distinguish it from the African and French marigolds, (tagetes genus) now commonly called marigolds. Calendula officinalis is grown for its beautiful flowers, edible petals and the many medicinal uses of its flowers, stems, and leaves.

The calendula is a member of the Asteraceae or daisy family. It is native to the Mediterranean through to the Macaronesia region and some areas of the Middle East.

Although sometimes classed as a warm weather plant they dislike the extreme heat of our summers so it is better in the Southeast corner of Queensland to plant them at the end of summer. To grow Calendulas prepare a well drained garden bed with lots of organic material in full sun (they will grow in partial shade but prefer the full sun). If your garden bed is not suitable they will grow well in pots and other containers. It is a very easy plant to grow, sow seeds directly into the garden beds or if you prefer into a seed tray. Extra seedlings can be planted around the garden wherever there is a space to be filled as they will attract many beneficial insects to your garden.

Mulch plants to stop weeds and conserve moisture in the soil and in very dry weather give them some water. They will grow about 40 – 45cm high and as wide and flowers can range in colour from lemon to bright orange and even a red colour and have an almost spicy aroma. As with most flowering plants the more flowers you remove the more flowers the plant will produce but leave a few flowers to go to seed, keep some seeds for next year even though they will self seed.

Aphids like the succulent calendula but can easily be treated with a soap spray. Snails, slugs and thrips can at times cause a few problems. In rainy, hot and humid weather they can also suffer with some mildew but treat with milk or sulphur spray.

Calendula flowers can be used as cut flowers to beautify your home, alternately the petals can be used in the kitchen. The simplest way is to add them to your favourite salad or add to your stir fry, cakes, puddings, stews, rice or even soup. Did you know calendula was once known as ‘poor mans saffron’ or that an extract from them is feed to hens to make their egg yolks golden. Calendula is also used to colour butter and cheese and to flavour confectionery, soft drinks and many baked products.
