Manon Floreat I prefer without. Is there another place for the plants to get sufficient light?

Design & Decor By Shelley I prefer without for sure.

movenready properties, LLC Definitely without!

AMN No houseplants or cut flowers in the window. It does nothing for the appearance of the home's exterior.

In addition, I find that homes look much better from the exterior when there are no curtains or sheers running across the windows. Of course, if someone's home is very exposed to the street or the residents have privacy concerns, going sans coverings is not an option.

Interiors International, Inc. Without!

onthefence I don't mind them - as long as it's one GINORMOUS well kept plant - a real statement piece. Small groupings of anything (including plants) in a front window aren't attractive to me.

Show to Sell, LLC No. Dated look. Better plain.

Aegean-Designing Whims I agree with no plants....but might suggest shutters or white wood blinds depending on your interior. I also agree that sheers look a bit dated and blinds or shutters would at least add some horizontal dimension.
Winter isn't the time to plant, but what about adding "matching" bushes on either side of the window when the season changes?

victorianbungalowranch I disagree! I used to live in Germany and there it is very important there to keep the windows looking nice from the street, so plants in front of lace curtains is very common there, along with displays of knicknacks, seasonal decorations, and whatever else strikes the owner's fancy. I miss these little touches that bring some color in winter and some individuality to rows of similar homes.

I say if you have window sills wide enough for nice plants, use them. A few more and more variation in size and height might be nice, and maybe a bit of something sculptural.

So what is wrong with old fashioned and "dated" anyway? Sure beats cold, lifeless and boring.
