Frequently Asked Questions

Why was iplantz started?

Iplantz started so that people in warm climate countries can access information on useful tropical and subtropical plants, including where they grow best. The reasoning is that the more knowledgeable we are about useful plants and where they grow, the better equipped we are when selecting plants for food, medicine and materials. Not only to feed, clothe, house and heal us but also to create economic opportunity.

What types of plants does the website feature?

The iplantz website features trees, shrubs and herbs that are useful to humans in some way, whether as food, medicine, material or in providing a service. And that will also thrive in warm climates, be it tropical, subtropical or Mediterranean.

Why are only some countries and towns featured on the website?

There are a couple of reasons for this. The main reason is the focus of the iplantz website on plants for tropical, subtropical and Mediterranean climates. As a result, only countries and towns within these climate regions are featured. Another reason is the lack of climate data for some towns, resulting in their omission. There are currently 3,532 towns in the database. If you would like to recommend a town to include on the website, please use the contact form to let us know.

How accurate is the Google Maps information showing where a plant will grow?

Where a tree or plant species will grow and be productive is generally determined by the type of climate, fertility of the soil and how well it drains. Of these variables, iplantz has reasonable access only to climate data, including the air temperature, rainfall and length of the dry season. 


Climate data stored for a tree or plant species, representing the climate it thrives in, is automatically cross-referenced against the climate of all towns in the database, and where there is a match, the town is published to Google Maps. There is no consideration given to soil fertility or soil drainage at the town level.  

What type of climate data does iplantz use to publish on Google Maps where a tree or plant will grow?

The climate variables used to determine whether a particular tree or plant species is a match for a town and will grow and be reasonably productive there include:


Air temperature

Annual high temperature

Annual low temperature

Low of the coldest month

Absolute low
Low of the warmest month
High of the warmest month

Rainfall
Annual rainfall
Length of the dry season (months)
Rainfall pattern (Humid tropical, Savanna dry winter, Savanna dry summer, Subtropical dry winter, Subtropical dry summer, Uniform and Arid (Dry)).

How can I become more involved with the work that iplantz is doing?

Signing up on the website allows you to upload photos of plants (and their uses) that can then be shared with the iplantz community.
