Tetra Mix Snapdragons are perennials that are often grown as annuals.
In zones with cold winters, these Snapdragons grow as an annual or short-lived perennial. They are moderately frost tolerant, but will die off in the fall as temperatures drop.

No, snapdragons are not poisonous.
The plant, flowers, and seeds are all non-toxic. These unique flowers are a great addition to a children's garden, and are safe to have around young kids and pets.

It is possible to grow Snapdragons indoors, but they are much better suited for being grown outdoors. Snapdragon seeds will perform best when started indoors 6-8 weeks before the last frost, then transplanted outdoors in full sun before buds form.

After the snapdragon’s flowers have withered, small green seed pods form. Allow these pods to mature, dry and turn brown. Once the seeds rattle inside the pod when shaken, they are ready to harvest. Crush the pods and shake out the seeds into a bag to dry. When the seeds are dried out, store them in a cool dry place to plant again another season.
