Firstly, can I say "Well Done!" on the website. I was thinking of creating a plant database for my own purposes but you have beaten me to it!
I'm learning about Permaculture and one of the core things I want to document is the connections between plants (companion planting, allelopathy, plant guilds for example). Would this be possible on this site? If so, can I help? I have some contacts in the permaculture circles who I'm sure would help us get the data structures right.
It's a lot of work and we're really only getting started now. We're actually redesigning the site and adding in new functionality at the moment including 'gardening companions' and plant guilds would work too but most people don't know what they are ;-). We're going to add them in a bit later this year.
We would like to make the plant profiles more complete but of course it's a huge amount of work and needless to say we don't make any money (not yet anyway). So any help is appreciated.
Fire me an email to mail@plantdatabase.com.au and let me know what you think would be useful?
