What Our Clients Say About Our Planters
These Manhattan Troughs are a cut above the rest, there’s no doubt. They’re sturdy and stylish, and light, light, light…until you fill them with your desired plantings. Mine are now home to happy bamboo which is growing healthily on my busy, street-side balcony. Thanks for great service too. Highly recommended.
Sophia Elliott – ROZELLE NSW 2039
We purchased 9 large Milano Trough Planters through Sigma – great service, wonderful product, good delivery and sound advice by Nick for our project. Our troughs have been placed on the first floor so we wanted to make sure that we have a quality product. Thanks for your assistance Nick – great.
Nic Hunter – Noosaville QLD 4566
We are beyond thrilled with our new Florence concrete cube.
We have planted a drooping Lilly Pilly and it is the centerpiece of our pergola area!
Thanks for the great service Sigma 🤗
