Make Borax Crystal Flowers

Why make borax crystal flowers?  Well, do you love the look of freshly cut flowers sitting in a vase?  I do.  But I never buy them because of my cursed black thumb.  While most people's cut flowers last for weeks, mine always start turning brown and wilting within a day or two.

Boo, black thumb!   

Last week our craft store had a sale on fake flowers.  I was so tempted to buy them, but they looked kinda cheesy and screamed, "I'm fake and I attract dust."

But I ended up getting the flowers anyway, because I wanted to make something pretty with them.  Here's what I came up with:  Crystal Flowers 

Make Crystal Flowers!

Yes.  My fake flowers are covered with real crystals... that I grew from Borax.  Lovely, aren't they?

Materials to make Borax Crystal Flowers

  • Borax
  • Water
  • Fake flowers
  • Pencils
  • String
  • Tape
  • Spoons
  • Containers
  • Paper Towels 


1.  Remove any leaves from your fake flowers.

2.  Tie the flower stems to your pencils using string.  Dangle your flower heads into your containers.  Make sure that the flower heads don't touch anything else (like the container's bottom or side, or other flowers.)  Adjust the placement of your flowers and string lengths as necessary.  Then, remove the flowers from the plastic containers.   (You don't want them to touch anything else because you don't want your crystal flowers attaching to other things.)

3.  Boil your water.  Pour it into your empty container.  Then, dissolve spoonfuls of Borax one at a time until the Borax no longer dissolves.  Then, place your flowers into your container and let them sit there for a couple of hours.

  • If your pencils keep rolling, use tape to keep them still.
  • You may have some undissolved Borax on the bottom of your container.  That's totally fine.

4.  After a couple of hours, pull the flowers out and see how crystallized they've become.  When you have enough crystals to your liking, set the flowers to dry standing up.

  • If you're having trouble removing the crystal growth from the bottom or sides of the container, simply pour boiling water into the container again to dissolve the crystals.

Enjoy your lovely and sparkly (fake) flowers!

  1. I did this. Very pretty. Just would've liked some measurements.So I would know how much Borax to use

    1. Good point. The next time I try this out I'll see how much I used. But honestly I just kept pouring it in until it didn't dissolve anymore.

  5. In the event that you need something a smaller seriously testing I have consistently adored orchids. I have tracked down that these flowers flourish in the washroom. They love the steam structure your shower. rose teddy

  6. It is said you never have a second chance to make a first impression. You should therefore take your time when choosing the appropriate gift. Fruit flower baskets are used by many as gifts. Flori cluj

  7. After reading the comments others have left in regards to your beautiful project, I feel compelled to share my thoughts about the measurements not being given. I would think it would be difficult to give exact measurements for the flowers since you do not know the amount of water needed for the size of the vessel used or the number of flowers being crystalized per container. I believe it is most helpful to suggest adding the borax a spoonful at a time until the borax no longer dissolves (as you suggested in your instructions above) to be more beneficial. Just this week I helped my grand daughter do a Science project of creating egg geodes & pipe cleaner crystals so I have a little experience in this matter. The flowers you have shown here are beautiful & I will definitely have to try my hand at making some. Thank you so much for sharing your experiment with us!!
