I've had this plant for 3 years now. It produced a single flower at the top for the first time this past October/November. The flower was white but died off before it fully formed due to a frosty night. It is now three feet tall. And growing shoots at he bottom. The nursery that I bought it from said a lady got it from Vietnam. Please help me identify it.
After further digging I believe you are correct. C. Asiaticum is much more pleasing to my eye. Question for you; the three off shoots that are growing, how long will it take for those to bloom and can i/how do i separate them?
I would wait until Spring before dividing the plant. The basics are the same as with any bulb plant. In your case, remove from the pot, wash away the soil so you can see where the new bulbs are attached. Using a sharp knife, slip it between the Mother bulb and the baby...gently "wiggle" the blade between them to loosen the offset, making sure to keep some root attached to the new bulb. Once separated, I use a tiny bit of Rootone (a rooting hormone with a fungicide added) to lightly coat any nicks in the bulbs...and then replant. Mine are all living in the ground so they get a bit of leaf damage in winter. If I remember correctly, the offsets can bloom the following year, depending on size.
The pics below I took today...you can see the frost damage to the leaves...in the Spring, I will remove the dried and dead portions that offer some protection to the bulbs over winter. I do hope this helps you some.
It's called Cemetery Lilly alot around here in Texas. I've just moved away from one I had for over twenty years. It was so deep in the ground (!) the I could not dig it or any part of the root up. So, I'll be looking for a replacement. Should be easy to find!
