Flowers begin life nearly white with a yellow eye that ages to a deep pink. In fall, kiwi sized fruits split open to gradually reveal heavy marble sized edible nuts within its chambers. Up to 9kg of sweet edible nuts per tree await the harvest basket. Similar taste to macadamia nuts when toasted. Provides a 35% protein flour.  Its also being considered as an oil source for biodiesel.

How to germinate Xanthoceras sorbifolium seeds:

Fastest, easiest and must successful method is to take a sharp blade and chip the seed coat away from where the seed root lies.  Once exposed, place in warm water for a couple of hours then place chipped seed into a bag containing barely moist fine bark mulch. Place in a warm place (25-28C). We’ve pricked out sprouted seed within a week to grow on under lights.  If you feel the need to, give chipped seed a brief swim in a dilute peroxide solution before starting warm stratification.  Seeds chipped Jan 26 2020 were ready to transplant into growing pots Feb 2 2020.
