Technically a Pelargonium, geraniums are hugely popular in gardens. They are very easy to grow, so are great for beginning and expert gardeners alike. In warmer climates, geraniums are perennials, but in much of the country, they are treated as annuals.


They bloom from spring to frost. There are three types of geraniums: zonal, ivy and scented. The zonal geraniums are the most familiar. They have flower clusters which rise above soft, velvety leaves. The flowers come in colors of red, white, pink, violet and rose.


This variety will generally grow twelve to eighteen inches tall. Ivy geraniums have branches that stretch out and droop, making them perfect for containers. The foliage is glossy and smooth. The ivy variety flowers come in pink, lavender, red and white.


The scented geraniums are more grown for the fragrance than the flowers. Gently crush the foliage in your hands to release the scent. The fragrance can range from rose, to chocolate, to mint! These geraniums are best planted in containers where you can reach out and rub the foliage.

Reader comment: I never realized that snapdragons were difficult to grow from seed. I planted seeds this spring and now my snapdragons (First Ladies) are moving right along and they look absolutely FABULOUS!! The colors look as though they are antique. I have marigolds also. I mixed about five different colors all together (bare-root) and I just go out each day and deadhead those that are discolored and they just keep blooming. Just keep them watered and plant them where they will get full sun each day. Although, you do have to be patient waiting for snapdragons to peek their heads through…Cissy
