Siberian Pea Shrub
Caragana arborescens
Family Fabaceae

Where winter hits forty below and summer forgets to rain, Siberian Pea Shrub keeps its promises: yellow pea blossoms humming with bees each spring, then pods of protein that chickens treat like payday. It is the homestead shrub for climates that break everything else.
Planted as a windbreak or fertility hedge, it quietly fixes nitrogen for the fruit trees downwind while asking nothing back — zone 2 hardy, drought-proof, ten to fifteen feet of dependable structure. Check your region's invasive list, then give the tough corner of the farm its match.

What each band means
- Bloom — flowers open — pollinators working, frost on blossoms is the danger.
- Prune — shape it now — cuts heal cleanly and structure is visible.
- Harvest — picking time — check ripeness every few days.
These are the species' typical months — expect them a few weeks earlier in warm zones and later in cold ones. Watch the plant, not just the calendar.
