Sweet Alyssum. If you haven't grown it, it is a lovely little plant. It can easily spread a foot wide and anywhere from 3 to 8 inches tall depending on the variety. It likes the sun, but will tolerate some shade. It also is very drought tolerant as well. And it smells ... heavenly. It comes in shades of white, pink, and lavender. And the biggest plus for me? Nothing eats it! Not deer, slugs, groundhogs, or squirrels.
Calendula. Also known as Pot Marigold, it is a pretty flower with bright yellow or orange petals. It tolerates full sun to shade and grows 1 to 3 feet in height. Its petals can be added to soups, stews, and salads giving the dishes a slightly spicy taste.
Petunias? Yes, Petunias. They love to bask in the sun, but also do well in partial shade. They won't survive hard freezes, but are considered cold tolerant to temperatures hovering around 39 degrees. They come in a variety of types and sizes.
Snapdragons. They love sun, but do their best when temperatures are cooler. The come in an array of colors and sizes. I happen to love the dwarf varieties. Keep them well watered and pinched back and they will continue to bloom right into Summer.
HAPPY SPRING GARDENING FROM THE POCONOS!
