wiki: "A biennial plant is a flowering plant that takes two 
years to complete its biological lifecycle"
"An annual plant is a plant that completes its life cycle, 
from germination to the production of seed, within one year, 
and then dies."
daijs def again "一年生植物のうち、秋に発芽して冬を越し、翌春に開花・結実
して枯死する草本"
We also settled on having both "biennial plant" and "inter 
annual" for the 越年草 entry based on the daijs def: 「越年生植
物」に同じ。二年草のことをいう場合もある。"
the daijr definition for 越年生植物 however also includes: 
"... 二年生植物。二年草。越年草。"

then there's this:
"Monocarpic plants that require vernalization to flower thus 
typically require two seasons to complete the life cycle and 
are usually classified as biennials or winter annuals. The 
term biennial is often used for plants that have an obligate 
requirement for cold exposure to flower, and the term winter 
annual is often used for plants with a quantitative cold 
requirement"

  Comments:
I think "winter annual" should be in there as well, but I'm 
not sure any longer it should be two separate senses (as 越年草 
now is)

Koj: "秋播き麦のように年を越して花を開き実を結ぶこと。二年生。"
Eijiro, Kagaku, Igaku all say "biennial".
Biennial: "a plant having a life cycle that normally takes two seasons from germination to death to complete; flowering biennials usually bloom and fruit in the second season" (Wordnet)
  Comments:
I think it's "biennial".
