How to say "blueberry" in Japanese

• ブルーベリー
  nounThe direct katakana borrowing of 'blueberry', covering the fruit itself; in contexts like desserts, jam, or fruit picking, this is the word to use.
  享子きょうこの見みえないところにブルーベリージャムを隠かくしてね。↗

  Please hide the blueberry jam where Takako can't see it.
• ミルティーユ
  nounA less common loanword, from French, listed for both 'blueberry' and 'bilberry'; it is seldom the word you want for the ordinary fruit, for which ブルーベリー is the direct term.
• せいようすのき
  nounReally the botanical name of the European bilberry (Vaccinium myrtillus), usually written in kana alone; it names the plant rather than the fruit as food, so it is not the everyday word for 'blueberry'.

Choose 「ブルーベリー」 for the fruit in everyday contexts; 「ミルティーユ」 is a less common loanword that also covers bilberry; 「せいようすのき」 is the botanical name of the European bilberry plant rather than a word for the fruit.
