What is the difference between a sedum roof and a wildflower roof?

Sedum and wildflower roof trays both share similar characteristics, in that they are aesthetically pleasing and provide several environmental benefits including reduced stormwater runoff and improved air quality.

However, there are some differences that will impact your decision.

As sedum is a succulent plant and drought resistant, there is minimal maintenance after installation, saving you a lot of time and money in the long run. 

Alternatively, whilst wildflower trays require more maintenance including watering and weeding, the wide range of flowers makes up for it as it creates a biodiverse environment where wildlife can thrive.

Ultimately, the biggest difference is aesthetics and maintenance. If you are after an extra splash of colour then a sedum and wildflower tray would be your best option.
