Typically, this flower will reseed on its own. You can encourage reseeding by avoiding deadheading, planting the original plants in a sheltered location and laying down a bit of protection in the fall, such as straw or a bit of mulch.

Pink Madagascar Periwinkles

I live in New Hampshire. Can I bring my hanging plant indoors (before frost kills it)?

Yes, this plant is often kept as a houseplant and should do well indoors. Cut down on watering, since plants typically use less water indoors. Also be aware that this is a poisonous plant, so it should be kept away from children and pets.

How far apart do I plant periwinkle plants? Do they need sand in the soil?

They aren't very picky. I wouldn't plant them too close together, as they will quickly spread and fill out an area. Maybe start a foot apart from each other. Be sure not to establish these where you will not want them in the future. They can be tricky to get rid of once you get them established.
