Calendula officinalis L. is the correct and accepted scientific name for this species of Calendula. It was first described by Carl von Linnaeus in Species Plantarum in 1753.

According to Plants of the World Online, the Calendula genus is currently in the Asteraceae Family and was formerly placed in the Compositae family. This website doesn’t say how many species are currently in the Calendula genus, but the 2013 version of The Plant list named 12 accepted species, 12 accepted infraspecific names, a total of 174 synonyms and 31 unresolved names. The Wikipedia lists 13 species and 13 infraspecific names.

There are currently 1,639 accepted genres in the Asteraceae family. It was named and described by Bedřich (Friedrich) Všemír (Wssemjr) von Berchtold and Jan Svatopluk (Swatopluk) Presl in O Prirozenosti Rostlin in 1820.

According to the 2013 version of The Plant List, there were 1,911 genera in the Compositae family which consisted of 36,701 accepted species and infraspecific names. The Compositae family was named and described by Paul Dietrich Giseke in Praelectiones in Ordines Naturales Plantarum in 1792.

I wonder what family Carl von Linnaeus placed the Calendula in when he named it in 1753?

There are many cultivars available and you can buy seeds just about anywhere seeds are sold. I bought my seeds of ‘Pacific Beauty Mixed’ from Baker Creek in the spring of 2012. I was hoping for a variety, but when they flowered they were all yellow.

USEFUL INFORMATION:
Family: Asteraceae
Type: Annual/ Perennial?
Origin: Unknown
Zones: 2-11
Size: 12-24” tall
Light: Full sun to part shade
Soil: Average, well-drained soil
Water: Average water needs
Propagation: From seed

Some information says Calendula officinalis is an annual, some a herbaceous perennial. Some people also say that self-seeding annuals are perennials, which may likely be the case with this species. Since I planted my seeds in the spring of 2012 and moved from Mississippi in February 2013, I don’t know if any returned that spring or not. I do know the Calendula fizzled completely out when the temperatures rose in the summer.

They like full sun but will not last when it gets too hot. As plants decline, you can cut them back and possibly have new growth and more flowers in the fall. Plants grown in to much shade will become straggly and not flower well. Flowers should be deadheaded to encourage repeat bloom.

There are many cultivars I would like to try because photos, as you know, are worth a thousand words. Photos and descriptions from seed companies can sometimes be deceiving and when you buy a mix you never know what you will get.

I would like to hear from you if you have any comments, questions or suggestions.
