Mine have just completed their blooming, they are planted in a mixture of:
alphora, sponge rock, charcoal and peat - 40%, 30%, 20% and 10%
respectively. They grow well in that mixture.

Chris,

I have two Cyms in bloom right now. One is a recent purchase and was
potted
in straight spaghnum when I got it. The other (Cym alifolium) I purchased
from Ray last year. It arrived in SH and I've kept it that way. It
rewarded us with two beautiful spikes full of flowers.

I'm a believer.
