The database is working very well and I encourage all permaculture designers to try it out. Especially the spreadsheet download. Let me know if you would like free access for a time to try it out.
The Natural Capital™ Plant Database is a repository of plant information for ecological design. Our partner designers have combined the best sources of plant research and documentation in order to provide the highest integrity for a wide variety of users. Whether you are a first-time gardener or an experienced permaculture designer, we hope you find the information you need to take your knowledge of plants and ecological systems to the next level. We use citations from multiple sources and provide detail on plant characteristics, tolerances and behaviors, ecological functions, human uses, concerns, and plant associates.
The Natural Capital™ Plant Database provides a variety of design tools from searching for plants based on selected criteria to creating ecological analogs. Downloadable query spreadsheets are formatted on most of the screens with all the information needed for sorting and refining plant choices.
The success of carefully designed plant systems is fairly predictable, but plants vary in size and growth rates based on numerous environmental factors. Check with local growers, nurseries, and institutions for the best species, cultivars, and management practices for your area. Source your plant materials locally or from growers at the same latitude, zone, and climate.
Comments and links to new sources for plant data are always appreciated.
