    I can't fault them at

    I can't fault them at all. The plants arrived in 3 days from QLD to Vic in very good condition, even with covid-19 restrictions. All plants are doing very well. Highly recommend this nursery for their prompt response with a personal touch.

    Sweet flag

    Very happy with this plant. Not something you can buying from your local hammerbarn (bluey fans will get this reference). So I’m thrilled to source it from an Australian business. This was my second purchase from Mudbrick, and they did not disappoint.

    I love your herbs and services!

    Thanks for providing the best quality herbs to me. I love the way you pack the herbs (I was worried before I received them). The herbs came in a very good condition and successfully transferred to my own pots. Thanks for the video and all the useful tips on how to grow herbs. My herbs won’t survive without them. I’ve recommended your website to my friends and I will definitely come back soon! BTW, I also love the range you choose. Some of herbs I’ve been looking for a long time and finally found at your place. Cheers!
