Early Bulam Korean Summer Squash Seeds – ‘Avocado Squash’, Ready 8 Days After Flowering

Korea’s Prized Summer Squash — Better Than Zucchini, Say Its Fans

Early Bulam is a beloved Korean summer squash nicknamed the “avocado squash” for its oval shape and smooth, glossy light-green skin. Its flesh is tender and mild — similar to zucchini but richer and more flavorful, according to loyal growers who refuse to go back. Ripe fruits measure about 4" in diameter and 5–6" in length, weighing around 14 oz. The real wow factor: fruits are ready to harvest in as little as 8 days after flowering, making it one of the fastest-producing summer squashes you can grow. Suitable for greenhouse and open field growing.
