Best Way for Collecting Snapdragon Seeds!

Snapdragon plants have beautiful and vibrant flowers resembling a dragon’s snout but morph into spooky little skulls when they wither and are ready to spew seeds.

For collecting the Snapdragon seeds, wait for the flowers to turn into dried seed pods in late summer. Shake the seed pods to hear any rattling sound, and gently tap them on a sheet of paper to collect them.

Snapdragon seeds are available in every nursery, but if you wish to grow a Snapdragon family every season, read on to learn about the seed collection.

Pollination and Seed Setting in Snapdragons

Snapdragons take about 2-3 months to flower, starting from germination.

They love the cool climate of spring and fall to bloom, but flowering can slow down during mid-summer.

Although the flowering becomes slow during this time, the remaining blooms lure pollinators like bumblebees.

However, if your garden is falling short on pollinators or you want to create hybrids, pollinate Snapdragons manually.

  • Collect the yellow, sticky, and bright pollens from the donating flower using q-tips and scrape it in wax paper.
  • Carefully open a closed bud from another plant by unfolding the petals.
  • Remove the anthers using sharp tweezers to expose the stigma.
  • Take the pollens on a fine-tip paintbrush and rub them over the stigma of the receiving flower.
  • Cover the recently pollinated flower using a mesh bag.
  • About 5-6 weeks after pollination, the petals will fall and unveil a green fruit, pod, or capsule.

  • Green pods present towards the lower end of the plant turn yellow-brown first.
  • Changes in color like this take place slowly in the pods hanging on the upper parts of the plant.
  • Pods dry off, and three holes are formed at the top.

One of the best ways to store the skull Snapdragon plant seeds is to leave them in the pods until sowing. This is the best way to avoid any mess.

But for collecting Snapdragon seeds all at once, dry the pods on a tray for 4 days. Later, you can follow these easy steps.
