Pollination & Production

Plan the partners before planting the tree.

Pollination reference

For fruiting plants, compatible bloom timing and nearby partners can matter as much as the cultivar itself.

Variety Selection

The cultivar can matter as much as the species.

These references help narrow the large number of named varieties to options better aligned with Zone 7A conditions, disease pressure and useful harvest windows.

Zone 7A Recommended Varieties

Caragana (species)Lorbergii (weeping form)

These are recommendations carried in the Organix Zone 7A reference database. They are not automatically the same as a cultivar personally proven by Organix on every site; site conditions and availability still matter.

Plant performance varies with microclimate, soil, drainage, water, maintenance and cultivar. Organix uses the library to narrow good candidates, then makes final selections around the actual site.

Edible and medicinal tags describe traditional or practical plant uses in the landscape and are not medical advice. Always verify identification, preparation and individual suitability before consuming a plant.
