As I wrote earlier for BULBS: My Hippeastrelia is a cross between the hexaploid form of Sprekelia and a tetraploid hippeastrum cultivar. A "cross' with hippeastrum again only did give me the hippeastrelia again, a case of apomixis. However a cross with the hexaploid sprekelia did give me genuine intermediates. All was checked by measuring nuclear DNA content So if you send me a seedling of your batch I can check it for you and you don't have to wait for flowers.
