Becareful for seeds ads from China, Hongkong, Twaiwan, etc; Actually, they're from North Vietnam! Take a deep look from those sellers' profile. Ebay Vietnamese sellers are very cunning and always lying about those seeds. You probably never get what you seen on ads!!! For example. Dwarf Washington Navel Organge seeds.
Dwarf Washington Navel Oranges are seedless and sold grafted to a rootstock. Therefore, the ads are totally cheating and bogus!!!
