Desert Museum Palo Verde (Thornless) 20 Seeds (032B)

Description

Desert Museum Palo Verde, Thornless
20 Seeds (032B)
The Desert Museum palo verde is a fast-growing deciduous tree of medium size that develops an upright canopy habit, 20-30 ft. tall, 20-25 ft. wide. In contrast to other types of palo verde, this cultivar has thornless chartreuse-green stems and branches. Vast numbers of lemon-yellow flowers are produced each spring for a dramatic display.
Desert Museum palo verde is becoming the top choice for landscapes and gardens in the Inland Empire due to its fast growth, thornless nature, intense flowering and delicate shade. It is easily pruned into a canopy tree that provides filtered shade and accent value in many settings. It grows best in well-draining soils, and exposed to full sun and heat. Summer water should be deep and infrequent; over-watering can lead to fast growth and weak branching.
The Desert Museum palo verde performs best in Inland Empire gardens mostly with normal winter rainfall. It easily adapts to our warm and dry summertime conditions; only periodic irrigation is recommended. The chart shown below provides a baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed.
Palo Verde Seed Germination
*
Nick the end of each Palo Verde seed with a utility knife. Press the blade against the seed coat until it is deeply incised but not completely punctured. Soak the nicked seeds in warm water overnight to further weaken the hard, impermeable seed coat.
*
Prepare a planting container for each Palo Verde seed. Use 7-inch plastic pots with at least two drainage holes at the base. Fill the pots with a mixture of 2 parts coarse sand, 1 part compost and 1 part perlite. Add water to the mixture until it feels moderately moist in the top 2 inches.
*
Sow one Palo Verde seed in each pot. Make a planting hole that is 1/4 to 1 inch deep. Place the seed inside the hole and cover it with a loose layer of the growing mixture. Spread a 1/4-inch-thick layer of mulch over the surface to help hold moisture in the soil.
*
Place the pots inside a lightly shaded cold frame. Warm the pots to around 70 degrees Fahrenheit using a germination mat. Check the moisture level in the growing mixture each morning. Add water whenever it feels barely damp in the top 1/2 inch.
*
Watch for the first seedlings in approximately one to two weeks. Remove the germination mat once the seeds sprout. Continue to water whenever the growing mixture dries out in the top 1/2 inch.
