Germination Information
Pre-treatment: Scarification of the hard outer seed coat using hand pruners or sandpaper, followed by a 24-hour soak to confirm penetration of the seed coat. Discard any seeds that float as this indicates insect infestation.
Establishment: Seeds should be collected from sources where other Parkinsonia species are not found to avoid cross-pollination. Collection should occur from mid-June to mid-July, as soon as seed pod and seed are dry but before they fall to the ground.
