Update on this cambria:
The spike in the first pics turned into this long spike. It's getting bigger and bigger and probably I will have lots of flowers.
The looking at the pic one doesn't see the real size of it but it is more than 55 cm (22 in).
In the meanwhile, a week ago I noticed a new one comming out and, yesterday, noticed another one (the smallest in the pic).
With these spikes, I think I will have flowers blooming during a big part of the winter. I always thought there would be a spike per plant. Is it true? Does this means I have more than one in this pot?
