Ground Not For Thy Daily Bread

Ground not for thy daily bread,
Leave me in my scented bed,
Ignore me not, lest I doth wither,
My name I leave you to consider.

A flower. The soil they grow in is not used for food, like wheat to make bread, but for their smell. A neglected flower will wither.

Shortest Word With All the Vowels

What is the shortest word in the English language to contain all of the vowels?

Sequoia, eulogia or miaoued are all good options, but there’s an even shorter (and more obscure) word with all the vowels and not a single consonant: Iouea. It’s not the kind of word you’d use at the dinner table, but it’s listed in the Wikipedia dictionary as a genus of Cretaceous fossil sponges.

If you got really tricky and tried to find a word that contained the letters in the phrase ‘all of the vowels’, you probably found, like I did, that there isn’t one. But it was still worth checking.
