Hey Alex,
just to give you the best advice possible:
I’m wondering if you have done you homework about Paph. sanderianum?! Do you know where it comes from, or how it grows in its natural habitat? What do you know about the history of that particular species? Don’t get me wrong, I can understand that you want one!!! I’m wondering if you know what Paph. sanderianum really means, and: what it means to some of the breeders involved in its history or culture. To understand and know about the things surrounding sanderinanum is part of the key to grow it successfully. To want a reasonably priced plant is a legitimate thing to ask for, but for someone starting with multiflorals it is equally important to have done their homework. If you don’t, you’ll not be successful with this species. How long it will take a 11 inch plant to start flowering depends on you, and your skill and set-up. There is no number to that question. It can take 2 years or it can be 8, or maybe it dies on the way. Tell you what: Why don’t you consider the primary-hybrids involving sanderinanum!? There’s stuff to be found that’s equally rewarding to grow like Angel Hair, or Prince Edward of York. You can pick up FS (Flowering Size) plants for the fraction of the price of a sanderinanum, and once you have flowered these plants, kept them alive, and learnt what it takes… come back to sanderianum. In the alternative talk to Sam or Jerry or Robert, and they will sort you out. There is more to Paph. sanderinanum than you might think. To get it right the first time and to save you time and money consider this advice, and you’ll have avoided mistakes that many of us have made (including myself)….
