Calendula officinalis L. is the correct and accepted scientific name for this species of Calendula. The genus and species were named and described as such by Carl von Linnaeus in Species Plantarum in 1753.
Plants of the World Online by Kew lists 12 species in the Calendula genus (as of 10-18-21 when this page was last updated). It is a member of the plant family Asteraceae with 1,677 genera. Those numbers could change as updates are made on POWO. The number of genera fluctuates quite often.
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.
Type: Annual/ Perennial?

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 too 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.
