What is a good plant to put along front walk with only 2 foot between?

box wood shrubs would look nice with small annual flowers

Succulents would look great along a path and will not grow to big and wild.

If the area gets lots of sun, you might consider mini roses. They do not get too big and are very big on blooms. Also, peonies, variegated bushes, or even small ever green bushes. If there is not much sun you might consider variegated hostas. I have grown them with great success in small areas that are shady. Hope this helps Sal. Here is a photo of a couple kinds of variegated hostas.

2ft between what? where do you live(weather conditions)? is it shade or sun? too many questions for good answer
