Has anyone grown Cardiocrinum giganteum? What a stunner!

I grew this way back in 2006. It bloomed and that was it! My mistake I think was to buy a flowering sized bulb as they are monocarpic (depending upon your source) and so my bulb had no chance to produce offsets (I suspect that the seller had removed all offsets prior to dispatch). Read the PBS page on Cardiocrinum and they say that they're not monocarpic but that the basal plate survives but there was no sign of that happening on mine. Maybe it was poor care on my part but if I try again I'll buy a bulb that is a year or two away from flowering.

@magnolialover or @pardalinum may have thoughts on the above as I'm not even approaching being an expert.

Well worth the effort of growing it in my opinion though. Mine stood near ten foot tall.

I have never grown it though the temptation has been great... I agree that purchasing a bulb a couple of seasons from flowering would be better. Plenty of time to settle in and propagate prior to blooming.

Ed McRae in his book "Lilies" states: "After flowering the main bulb dies, but under good conditions it will have produced a number of offsets that will flower in a few more years". It likes light shade, summer moisture and rich humus soil.

I read somewhere that it produces seeds fairly well.
