The details that matter
Everything that ships
- Black locust seeds (100)
- Autumn olive seeds (50)
- Siberian pea shrub seeds (75)
- Alder seeds (100)
- Germination & planting guide
Honest note: black locust in particular spreads by root suckers and can colonize aggressively. Plant it where you want a thicket, not next to a tidy bed — it is a feature or a headache depending on placement.
Questions, answered
Why do seeds need scarification?
These hard-coated tree seeds will not germinate until the coat is nicked or cold-treated. The guide gives exact steps per species.
Is autumn olive invasive where I live?
It can be in some regions. Check your state noxious-weed list before planting — the guide flags this.

Why we grow it this way
Build fertility into the system
Nitrogen-fixing trees are the quiet infrastructure of agroforestry — plant them among your crop trees and they pull nitrogen from the air and feed the whole guild. This collection gives you four species (black locust, autumn olive, Siberian pea shrub, and alder) and over 325 seeds, enough to establish real fertility corridors.
Each species comes with the scarification and stratification steps it needs, plus a density guide for alley cropping and silvopasture.
What growers say
Great fertility starter
Good germination after following the stratification steps. The pea shrubs are already fixing nitrogen visibly around my fruit trees.
Read the invasive note
Seeds sprouted well. Glad the guide flagged autumn olive — I swapped it for more alder for my region. Sensible collection otherwise.
