They come in popular white, pink, creamy yellow and lavender colors, but pink ones are available in both seeds and seedlings. They are difficult to start from seed, so it's best to choose those started in six-packs. Can be used as borders or background plants.
Snapdragons prefer cool weather, but grow in sunny spots through summer.
They are good for cut flowers. These fragrant flowers are most striking in pink, white and lavender. They are mostly marketed as mixed varieties, but you can find the long-flowering varieties in seedlings of one color only. Stocks thrive in cold weather, but do just fine in sunny summer gardens. Some shade and plenty of water help them along.
