Found in Shira HaShirim (Song of Songs) chapter 2:1
אֲנִי חֲבַצֶּלֶת הַשָּׁרוֹן, שׁוֹשַׁנַּת הָעֲמָקִים
אֲנִי = I (am)
חֲבַצֶּלֶת = rose or crocus (of)
הַשָּׁרוֹ = Sharon, a plain on the Mediterranean
שׁוֹשַׁנַּת = lily (or lily-like flower) (of)
הָעֲמָקִים = the valleys (plural form)
"I am a rose of Sharon, a lily of the valleys"
There is also an interesting bit in Wiki about "The Rose of Sharon", if you are interested!
