These seeds are from Parkinsonia aculeata, also known as Jerusalem Thorn, Mexican Palo Verde, and Horse Bean. This tree likes to live in full sun where it can grow to 30 feet high and blossoms from late Spring until early Summer. The bright yellow blossoms are very fragrant, so they attract a wide variety of birds, bees, and butterflies. The pulp inside the seedpods is sweet and delicious. The leaves and seedpods can be used as animal feed, and the wood is used in carpentry, to make charcoal, and burned as fuel. This is a larval host plant for the Clenchs Greenstreak butterfly, and the Ofatulena luminosa, and Dot-lined Angle moths. USDA Hardiness Zones 8b to 11.
