Adam, Have you tried your hand on Clivia seeds? The variegated ones are very expensive and seed is cheap if ordered from China on EBay. Maybe a $ a seed. For a plant worth hundreds of dallars. Check it out. Stush
Does it have a Caudix forming yet? May want to remove the buds to give the strengh to the main plant. Or at least soon after they bloom. Anywhy, nice going.

You grew your A. polyphylla from seed? I've been wanting that but they are usually rather pricey for the full size plant. Where did you get your seeds?
