A plugin or a theme for Wordpress to create a free online database for seeds and plants.

Hello! i’m looking for a plugin or a theme to create a free online database. I’ve found many themes in the Directory category of Wordpress but it’s all for cars business, rents and restaurants.

I want to create a free database for seeds and plants, where users can browse the database and find a seed/plant, where to find it and so on. I don’t need any map. Who can suggest me a theme or a plugin to do this?

thank you!
