Blue Palo Verde has a beautiful green truck which can photosynthesize! (Parkinsonia florida). These seeds were harvested from my giant Blue Palo Verde tree growing in the Western Sonoran Desert of Arizona. Germination: Soak seeds 1-2 nights in lukewarm water. (Scratching the surface can improve germination). Sow seeds 1/4 deep of a well-draining soil mix & lightly cover. Keep soil warm & moist. Place in a sunny location. You should see them sprout within 1-2 weeks! If trouble germinating, attempt nicking the seeds surface. With over 50 seeds you will have plenty of attempts & enough to start a forest of Blue Palo Verde trees! These trees are very drought tolerant once established. Allow soil to completely dry before watering. Blue Palo Verde 50+ Seeds, Parkinsonia Florida
