Here we go again.
I wrote "In the vase are yellow flowers" and DL marked me wrong for omitting "there." Please, please......."there is/are" is optional in natural, normal English. "There" is more common in spoken dialog, but still not required. "Is/are," in these constructions, without "there," is perfectly good, common English.
@Erik355794 - In Russian, things either stand or lie down depending on whether they're vertical or horizontal. Something like books can go both ways (if they're lying down on the cover then they're lying down). I suppose flowers could also be lying, but then they wouldn't be in an upright vase.
