Such a mystery! This amazing plant can create some colour magic but Oh Eucalyptus, why do you tease so! Has it been teasing you too? Eco printing eucalyptus is my fun adventure…

types of euca

All kinds of Euca:

I know… You have wondered if I was still alive! Yes, for sure. I have just been dealing with testing what I already have in the house since shopping is out of the question nowadays. I have very carefully saved and stored any and all eucalyptus that I can find. Do I know the exact name of each specie?! No, there are hundreds!

Getting it in Canada is a challenge. It has been more common lately in wedding arrangements as well so I have also ‘begged’ some brides! (with promise of printed keepsakes) I even bought some live plants that would just not thrive no matter what I did for them!

And thank you! A lovely lady in Australia also ‘snuck’ some through the mail to me! Thank you! Anyways, I am determined! I am not going to let it beat me down.

tools of eco printing

Keep & Rehydrate

Eucalyptus does not need any special storage, just save as is to dry for later use. Once you are eco printing eucalyptus give it a good soak. Some warm or hot water will speed the process. Some eco printers soak for days prior to printing. I only soaked in hot water for about 30 minutes. The fragrance comes right out away…

Eco printing eucalyptus is so mysterious! I have always stared at the euca trying to decipher which one will print red or orange. Is there a way to tell? That seems to be the question. There are some species from the florist with seed pods that also print.

These are some of the collection that I have. I often see that the rounder leaves do print quite red. Another thing to keep in mind is that eucalyptus loves to print on protein fibre; like wool or silk.

On protein fibres you do not necessarily need a mordant when using eucalyptus other than a bit of iron. I like defined prints so I tend to overuse iron. In this case I dipped this wool into a weak iron solution and I used a weak iron blanket that was used before.

Woohoo! I did get some good colour from the large long leaves that came from Australia! A girl from Canada can envy!

However, even though the iron blanket was washed, it did sadly transfer some dark stains to the wool. Correction, any print can be quite beautiful & acceptable as it is design! It all depends what you are striving for. Sometimes very clean and precise is boring, like a predictable fabric print.

Do not despair!

There is some hints of colour here! Yay! I’m not giving up! Sometimes we need to put it away for a bit and look at it with ‘new eyes’ after a while!

Every fabric is different:

Even though it is wool or silk the characteristics of the fibres will make a difference. Some are very fine and close and some are more lofty and fuzzy. Each will affect the outcome. It’s like hair; we all have it but it’s so different on each of us.

This is a up-cycled virgin wool blanket from many years ago. They print well but there are things to keep in mind due to the nature of the weave. The wetness of the fabric will also translate into how distinctly the print shows.

Mirror mirror!

It took me a while to clue in! Every time I’d see amazing printed euca it would be mirrored! Yes, it does act differently than other leaves and will print from both sides; how novel! It gives a lot of options for placement & design. It also means less leaves are needed. Just wait and see what these prints will become!

temperature gun at 184 degrees

Unconventional me:

Yup, I use the microwave to supply my heat. I do not use any metal, have a dedicated unit but I am somewhat limited in respect to size.

I believe that euca likes a long use of pretty high heat, some printers stating as much as 5 hours of simmering or steam! I bring up to desired temperature and then insulate under thick blankets where they hold the heat well until another short ‘zap’. An oven works similarly, turning on the element when the temperature goes down. I aim for just under 200 degrees fahrenheit.

I would say that my prints had plenty of time to release their colour, almost 5 hours of zap&insulate.

Habotai silk is always a good accepter of prints as shown here. The dullness of colour however is from the use of iron I believe. The silk was dipped in what I felt was a weak iron solution. I am an artist, not scientist so I tend to not measure…

leaves being removed

…but wow! I am so happy to see these colours! The large round leaves seem to be the specie that is performing for me! Many factors will affect the print colour other than specie; like time of year and location. So how do you know?! Test! and take notes to try to repeat…

No, there are not heart shaped leaves, but you can cut the leaves! Have fun and don’t put so much pressure on yourself.

pretty prints on wool

Even when they are not all red or orange, there are some wonderful tones that can come from eucalyptus! The added details from the seed pods compliment nicely.

dark prints on wool

Here’s a tip:

Since I tend to get a bit heavy on the use of iron, did you know that you can lighten your prints if they are too dark from the iron? Do you get really ugly dark stained fingers from the iron? A solution of citric acid (teaspoon per bucket or so) will lighten your prints. Do be cautious and watch carefully as you do not want it to get too light. You can dig your stained fingers into a half of a lemon… clean and bright fingers! You’re welcome!

lightened wool more bright

Note how this print did get quite a bit richer in colour since some of the dark has disappeared.

I am I there yet?! Not quite, but that keeps me interested! Is there a perfect answer/recipe? Probably not, as nature always has something up it’s sleeve. Enjoy your prints and enjoy nature.

Check out what these prints ended up becoming! I am so happy that I can spread some ‘Love’…

  1. Barb the prints the eucalyptus made are gorgeous thank you for sharing them. I am surprised that you cannot get sprigs of the plant. I just checked online and Ebay and Etsy have the sprigs for sale and I am sure there are other sources. Is Canada that locked down that you can’t order offline? Ridiculous if so.. See if your local florist has some they cannot use or ask if they can save unusable sprigs for you. They usually clean out their refrigerators once a week. They can also order for you. BTW the heart print with the long Euc leaves on the bottom is absolutely gorgeous. Thank you for sharing all you do with us 🙂

    1. Yes, I have a sweet florist who offered a few sprigs for $20, one did print quite nice so once we are out of lockdown, I’ll pursue some more. Just like it took a while to find my favourite maples…

  2. Hi Barb. I’m in Australia, where eucalyptus leaves abound. I did a workshop with Gumnut Magic on printing euc on cellulose fibres like cotton. Good results can be achieved by soaking leaves in a bucket of water for at least 6 weeks ( I’ve had some soaking for 6 months!). Using well scoured stretch knit cotton jersey also helps as it wraps well, making good contact as it stretches and grips slightly. Would love to have sent you some photos but couldn’t copy & paste into this text box arrangement. We dipped the wetted fabric into a weak iron water before laying out the leaves with thin twigs & small nuts attached. Boiled for about 90 mins. I used stretch cotton and a stretch cotton/hemp with good results.

    1. That sounds like it was loads of fun! I paid a florist to order some euca and I had to take whatever spcie came, no choices. $40 for a few branches is quite steep, and they did not yield any red. I had some soaking so much that it went moldy. This was just a few first tests, and I’m sure not my last. I have been making friends with florists and even offering a trade. Maybe it’s just not for a gal from Canada… besides I get amazing maples! Thanks for the help!

  3. Hi Barb
    usually the silvery leaved eucalypts give the best orange coloured prints. They print much better on wool and silk (protein fibres) More difficult on cellulose. You will have to tannin dip and mordant carefully and probably steam for longer on cellulose fibres but the colour will probably not be so intense. This has to do with the structure of the fibres. Protein fibres have “scales” which allow the dye to penetrate more easily whereas cellulose is a more rigid structure so the tannin and mordant is needed to increase the ability to get a reasonable print. Hope this helps

  4. Thank you for all the information you share. I print with mainly eucalyptus and have access to many varieties. I have found that some need vinegar in water dip before placing on fabric to bring out colour also any that print red on wool and silk , may not do so on cellulose fibres all part of the interesting game of eco printing

    1. Yes, I have heard discussions on that as well. I believe India Flint (the queen of Eco printing) did say it wasn’t needed. But as far as I’m concerned rules are made to be broken… Someone also said to use an alkali pre-dip 🤷🏻‍♀️

  5. Your work is beautiful Barbara! Thank you for clear directions. Your experiments have helped me with my printing. I don’t use a microwave but I admire your results.

    Happy Printing!

  6. I have been wanting to try your microwave method and was all set to give it a try this weekend when I got your email on Friday. The grocery store near me stocks various eucalyptus so every few weeks I buy a few bunches (3 for $12) and rehydrate when needed. Yesterday I did a couple pieces of silk and wool that I dipped in iron and got nice prints – mostly browns but a little orange on the wool. When I steam I usually get a lot of orange but I don’t usually use iron. Will have to do some more trials. Thanks for your generous sharing of varied crafts. Now I have to make mittens with all the sweaters I’ve been collecting.

    1. I tend to be a bit heavy on the use of iron… I like defined prints. I am not quite familiar with the euca yet and do want to experiment more. It just seemed wrong not to use any iron. Too much of other life gets in the way of printing… More to come; I am so stubborn and will get what I want from the euca. Haha.

  7. Hi Barb, I have also started to experiement with eucalyptus and, like you, I can’t find a local natural source so I have been using leaves that I purchased on line. I found a seller on Etsy who sells the leaves for making tea and she kindly agreed to send me some whole leaves – the very long variety – and I was so delighted that I got good strong oranges from them when I used them on wool. I used a weak PAS solution as a mordant. On silk I got yellows and lighter oranges without the use of any mordant at all. In both instances I soaked the leaves for about 10 minutes before using them and steamed for around 4 hours.. I also experimented using broken up leaves – I crushed them into small pieces and just sprinked them over a piece of cotton that I had mordanted using iron. I loved the abstract pattern that resulted – some of the pieces printed bluey-grey and some a dark reddish brown. (as you say the leaves print from both sides so this hotch-potch method worked well).
    I love your work and am in awe of your artistic talent and skill.

    1. You have me intrigued as I have a shop that sells pretty well every odd spice and oddities and have seen the full long euca leaves sold in packages for tea. I am going to test them again. Fingers crossed, and I will try the wool. I have a pretty good collection of wool blankets! Thanks for the info; much appreciated!

  8. I stumbled into my version of “eco printing” while isolated in the north woods of Wisconsin, USA, before it was all the rage. Since then, I have studied other’s approaches and tutorials. I have been repeatedly impressed by your work, generosity in sharing, and humble curiosity. Thank you for everything you do, share, and for being you. I hope to meet you sometime. Best wishes!💫 @moonpearpress
