Answer:
I am partially baked. I am not completely lit. I am a portion of the moon. I am lesser than full wit. I am a divider of the hour. I am not a total lie. I am a sibling through one parent.
I am all around yet to me you are half blind. Sunlight makes me invisible and difficult to find.
I am long and slim works in light. Has but one eye and an awful bite.
rub me and a genie might appear
I have a name written on me, but it isnβt my name. Men plant me, but I never grow. They look at me and see their future, rotting in my bloom.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
