Snapdragon Flower

Snapdragons are a type of flowering plant that comes in many different colours. They are native to the Mediterranean region and can be found growing wild on hillsides and rocky outcrops.

Snapdragons grow beautiful striking flowers that resemble a dragon’s head that literally opens and closes its mouth when squeezed. After these beautiful blooms have faded it’s important to know how to deadhead snapdragons so they don’t go rogue and start trying to take over your garden!

This article will teach you what to do with snapdragons after flowering plus more.

What are Snapdragons?

Snapdragons are actually named Antirrhinum, but they are far more commonly known by their nickname due to their resemblance to the mythical creature the dragon.

Much like many members of the plant world, the family of plants that the snapdragon belongs to is still being debated. They used to belong to the family Scrophulariaceae (same family as the Buddleia) but following DNA research, this has been changed to Plantaginaceae (the plantain family).

How Long do Snapdragons Live?

Although snapdragons are perennials, they are very delicate and do not cope well with extreme cold. This is why in the UK most snapdragons are grown as annuals and planted every year.

In warmer climates with the right growing conditions, snapdragons come back year after year (USDA Zones 7-11).

Do You Deadhead Snapdragons?

To extend the flowering season, it is a good idea to deadhead your snapdragons as soon as the blooms begin to fade. The removal of the flowers, once they are spent, will keep your snapdragon blooming throughout the summer.

Deadheading snapdragons, once the blooms have faded, will also prevent the plant from going to seed which will take up a lot of its energy supplies which could be better spent on new blooms.

Note: If you wish to collect snapdragon seeds, wait until towards the end of the summer and collect the seedpods that are produced after the last blooms have faded.

How to Deadhead Snapdragons

To help keep your snapdragons at their fullest potential, deadheading spent blooms as they have begun to fade will keep the fresh new flowers coming.

You will want to take your clean, sharp pair of secateurs and cut just below the flower stem but above the next set of healthy leaves.

If your snapdragon is looking a little leggy and the stems start growing long without any new flowers sprouting up near them, cut off the stem just above where you see the new growth. This may slow down the production of new flowers, but you will be rewarded with vigorous growth.

Do not be discouraged if during peak summer the blooms do not open immediately, as soon as it cools a bit, they will be back!

How to Collect Snapdragon Seeds

Although snapdragons will bloom throughout the summer, it is best to continue deadheading your snapdragons until towards the end of the summer and collect your seeds from the last blooms of the year.

Once the blooms have faded, the plant will begin seed production and the seed pods will form where the flowers once were.

Collecting the seeds is easy enough to do and great fun for kids – probably because the snapdragon seed pods look like little human skulls.

Once the seed pods are completely dry, you will want to give the seed pods a little shake and if you hear/ feel the seeds rattling around, the seeds are ready to go. If not, leave them to dry for another week or 2 and try again.

Once the seed pods are ready, you can just nip them off between your thumb and forefinger. Once collected, you can store the seeds in a cool dry place in an envelope until you are ready to plant them.

Conclusion

After flowering, deadheading is important to keep your blooms looking blooming marvellous throughout the summer.

Deadheading is easy to do, and once blooms begin to fade, remove them just above the new leaf growth but don’t forget, if you do want to save some seeds for planting next year, wait until the end of the summer and save the seeds from the last blooming flowers of the year. That way, you can enjoy your snapdragons for as long as possible.
