Name plants that are perennial and spill over built in planter boxes

i live in central pa. some friends built planter boxes on back and sides of my home. they have some height, so i don't break my back to plant or water. i'd like suggestions on perennials that will spill over the sides and add interest to the wooden boxes even in jan. and feb.

    There are no winter perennials that will spill over or survive your zone.Try using cutting from pines and add berries.
  • Geraniums.

    Perennials will go dormant in the winter and my not survive the winter freeze in a planter. You can try juniper which does not go dormant but it does not flower.

      thanks, lynanne3, i'll take a look at juniper. if all else fails, i'll try to get the lady at my old house to share. i'm aware that jan/feb don't allow much to thrive. i know ivy will. and a creeping speedwell lookalike looks dead, but comes back year after year. thanks again.

    thanks janet, so i guess, it's ivy or ivy hybrids?

    there's a perennial that looks like "creeping speedwell", except that the flowers are yellow. i grew it for decades at my old house. i didn't take any w me; now i can't find it. is there anyone out there who knows of this perennial ground cover?
