Whether you're planting in a backyard, a balcony pot, or a food forest in the making, this library is here to help you find species that align with your space, goals, and growing conditions.
Every article follows a structured format that includes:
-
A Quick Reference Box for at-a-glance information

Notes on Health Benefits, Toxicity and Soil Health
All entries are based on personal experience right here on our off-grid homestead in rural Portugal. I’m tracking the success and struggles of each plant to create a resource that’s as transparent and practical as it is inspiring. I will add photos as we grow, and community comments and tips are always welcome.
Whether you're looking for drought-tolerant perennials, fruit trees for specific USDA Hardiness Zones, or nitrogen-fixing understory plants for a food forest, the Plant Library is designed to grow with you.
