Q: Twice in the last few days I’ve seen the hibiscus shrub (or its blossoms) referred to in the plural as “roses of Sharon.” I would have thought it more correct to say “rose of Sharons.” Is there a rule for such plurals?
A: The usual rule for pluralizing a compound term that’s split into parts, with or without hyphens, is to put the plural ending on the most important part, as in “attorneys-at-law,” “brigadier generals,” and “mothers-in-law.”
The compound common names of plants are usually treated the same way, especially when the key element is a noun at the end: “African violets,” “fringed bleeding hearts,” “morning glories,” “northern blue flags,” “pussy willows,” “trumpet vines,” and “Virginia creepers.”
However, things get fuzzy when the important term is elsewhere in the compound, especially if it’s being used loosely. A “lily of the valley,” for example, isn’t really a lily, nor is a “rose of Sharon” a rose. The terms “lily” and “rose” are being used figuratively in the sense of “flower.”
Similarly, the “Johnny” of “Johnny jump up” refers to a violet, while the “Jack” of “Jack in the pulpit” is a flower-hooded spike. And “forget-me-not” doesn’t even have a key word. It originated as an English translation of the Old French expression “ne m’oubliez mye.”
We haven’t found any special rules for pluralizing such horticultural compounds. And the online standard dictionaries aren’t much help—only a few include plurals for these compounds—and the entries are inconsistent.
Merriam-Webster, for example, includes both “Jack-in the-pulpits” and “Jacks-in-the-pulpit” as standard. American Heritage has “Jack-in-the-pulpits” and “Johnny-jump-ups.” M-W, AH, Collins, and Dictionary.com list “lilies of the valley” as plural. None of the dictionaries have a plural for “rose of Sharon.”
A search of garden websites indicates that some gardeners make the key word plural (“roses of Sharon”), others pluralize the last word (“rose of Sharons”), and still others add a plural noun at the end (“rose of Sharon bushes”).
A search of the iWeb corpus, a database that contains 14 billion words from 22 million web pages, came up with these results: “rose of Sharons,” 30; “roses of Sharon,” 19; “rose of Sharon bushes,” 43; “rose of Sharon plants,” 19; “rose of Sharon trees,” 16; and “rose of Sharon shrubs,” 15.
With no lexical guide and usage up in the air, pick whichever one sounds best to your ears. We’ve planted a few over the years, and “rose of Sharons” sounds more natural to us than “roses of Sharon” or “rose of Sharon bushes.”
As we’ve said, the rose of Sharon isn’t a rose. In fact, the common name may refer to several different plants, including Hypericum calycinum, a flowering shrub native to southeast Asia and southwest Europe, and Hibiscus syriacus, a flowering shrub native to east Asia.
Although the common name has biblical roots, none of the plants now called “rose of Sharon” are likely to have grown in ancient Israel.
In the Song of Songs (or Song of Solomon) 2:1, the maiden who is one of the two main speakers refers to herself in Hebrew as חבצלת השרון, or havatzelet hasharon. Havatzelet is a flower that has been variously identified as a crocus, lily, daffodil, or tulip. Hasharon is the plain of Sharon along the Mediterranean coast of Israel.
Early English versions of the Old Testament translate havatzelet as “flower.” The Wycliffe Bible of 1384, for example, renders havatzelet hasharon as “flour of the feeld” while the Coverdale Bible of 1535 has it as “floure of the feelde.” It was translated similarly in earlier Greek and Latin versions of the bible: ἄνθος τοῦ πεδίου (anthos tou pediou, flower of the field) in the Septuagint, and flos campi (flower of the field) in the Vulgate.
The Geneva Bible of 1560 was the first English bible to translate havatzelet as “rose”: “I am the rose of the fielde.” The Oxford English Dictionary says “it is not clear why the Geneva Bible uses this particular translation, rather than the generic flower of earlier English versions.”
The first OED example for “rose of Sharon” is from An Exposition Vppon the Booke of the Canticles (1585), by the Puritan clergyman Thomas Wilcox: “I Am the rose of Sharon.” (The Canticles is another name for the Song of Songs.) The King James Version of 1611 uses the same wording as Wilcox.
