How long have you owned the plant? Have you changed the growing conditions? What is your watering routine?

I always found it strange that John Hummer failed to mention the wide mid rib as a defining character in the cultivar description.

The ISHS states 'The ICRA should try to ensure that the registrant is prompted into giving an account of characteristics that are likely to be diagnostic. Descriptive information recorded will vary greatly between some denomination classes.' Personally, I don't think the the cultivar registration of Hummer's Giant is particularly descriptive and I do not believe it to be sufficient to allow differentiation of the clone.

Some years ago I received a HG from a UK growers, who had been growing it for many years and I believe that it was distributed throughout Europe as HG, but it has a different picther shape than those I have seen in the US. As I mentioned before, there may have been more than one clone distributed by John Hummer as HG and I also think that there are a lot of mislabelled ones out there too.

I'm not sure that anyone knows what the true Hummer's Giant looks like, as the cultivar description does not describe the shape. In addition, it suggests that John Hummer may have distributed more than one clone with the same name. The cultivar description can be found here: http://www.carnivorousplants.org/cpn/Species/v29n4p116_122.html#hummers Here you can find pictures of what people have called Hummer's Giant, but you will see that there are some variances: https://cpphotofinder.com/cephalotus-hummers-giant-2011.html @dimitar might be able to help with identification, as he

To be honest, the cultivar description for Hummer's Giant is dreadful and I don't think anyone could say with confidence that they have the plant described in the description.

In my experience, it is not a good addition to Cephalotus mix. You would be better to use perlite. The only CP I use vermiculite on is Mexican pinguicula.

Good light and cool conditions seem to be conducive to colouration. The best colouration I've seen is on plants in the cooler months. If you take a look on my website linked below, you will find a couple of clones with really deep colouration. These were growing in a climate which is very hot in the summer but gets cool in the winter.

That's a very good growth rate. I think that the production of leaves may be seasonal. I grow many of my Cephalotus under fluorescent lighting and don't get many leaves, but the ones grown on windowsills get more. The ones under fluorescent lights get the same daylight hours throughout the year and the lights produce heat, but the windowsill ones get seasonal variances. Personally, I wouldn't be concerned about the lack of leaves, as the plant looks healthy and to be growing well.

I've tried top dressing of gravel and the moss came through. Im now trying a much deeper top dressing using granite gravel and so far it is moss free.

There are certainly a lot of named clones out there that are not worthy of naming.

You and I share the same likes for that. Apart from my location plants, most of my ceph collection has been reduced to those with unusual pitcher shapes or sizes.

Hi @Bidde, I like the pitcher shape.

@Bidde, is that Squat?

I presume the one you have seen is the one that creates a rosette of leaves? If so, then it is not to my taste, however it is unusual and would qualify for cultivar status.
