Add Some Snap to Your Garden with Snapdragons!
Snapdragons are easy-to-grow, hardy annual flowers that grow well for most people. Snapdragons get their name from their flowers that “talk” when the flower’s corolla tube is squeezed. Kids cannot resist snapping snapdragon flowers.
How to Grow Snapdragon Flowers
Snapdragons need full sun (six to eight hours) and moist, well-drained soil. Plants tolerate acid or alkaline soils. They do not flower well in the shade.
Snapdragons bloom best during cool weather when the temperatures range between 40 F and 80 F. Keep snapdragon plants well-hydrated and as cool as possible to extend the blooming season as long as possible into the summer.
Fertilize snapdragon plants with a time released fertilizer (like Osmocote) or use a water-soluble fertilizer (like Miracle Grow). Plants grown in well-amended garden soil need less fertilizer. Too much fertilizer makes tall varieties floppy. 
Can Snapdragons Grow in Pots or Containers?

Snapdragon Height and Plan Form
Snapdragon plants are upright in form. Flowers are formed on the upper part of the flower spike. After the main flower spike flowers, shorter side branches continue to grow more blossoms. Cut off old flowers to encourage new blooms. Flower color ranges from reds, pinks, yellows, white and maroon and lavender, but not true blue or purple.
Grow Snapdragons from Seed
Snapdragons are easy to grow from seed. Sow seeds indoors in high-quality seed starting mix. It can take up to 3 weeks for the seeds to germinate.  Snapdragon seeds need light to germinate. Sprinkle seeds on the soil surface and lightly press into the seed starting media to ensure good contact with the soil. Start six to eight weeks before you plan to transplant the seedlings into the garden. Use fresh seed because germination rates fall rapidly with age.
