For a number of years I've only grown HG Cephs. However, in the past two years (or so), I decided to add some genetic diversity and acquired several other plants. Since most of these plants are in the same conditions (under lights in back basement room - temps currently in low 50's*F and are flowering size (or close)) - I thought it might be interesting to try to compare a few of them.
First up is the "German Giant" - not flowering size and also not in the back basement room. It's still in the basement - just not in the colder back room. So far, an unremarkable clone ...
Next up is one of my favorites - I received it labeled as "Squat". It has proven to be a very vigorous grower with some interesting coloration (that I'm not really able to capture in a camera). The 1st pic shows the clump of pitchers with the top two having nectar covering their peristomes** & the second shows the general shape of a pitcher:
This next pic is the primary reason for my post. When I wander into that cramped nasty little room every week to water these guys, I thought I noticed a significant difference in the size & shape of the teeth of the peristome (there's also multiple other differences - like under-lid design, mid-rib width, colors, etc - but the differences in the teeth grabbed me). The pitchers are a bit different in size but not by a lot. I'll be interested to see if these differences remain ... ("Squat" on left & 'Hummer's Giant' on right):
Here's a comparison of a "Czech Giant" (left) and a full grown seedling from a selfed HG Ceph. These plants were potted into the same size pot with the same media mix over a year ago and have remained side-by-side since (outside for summer & winter under lights). In addition to the obvious color differences, the Czech plant has kept all it's pitchers while the seedgrown plant has done the 'winter thing' and mostly moved to non-carnivorous leaves. The SG plant has also retained the robust peristome teeth and wide mid-rib from it's parents (while the Czech plant has neither).
For anyone who is doubting the viability of the Ceph seeds in the ICPS seedbank this fall - pic from yesterday (as mentioned in another thread, this pot will likely find it's way into the NASC auction):
** I'm assuming that I can call the pitcher-rim area on a Ceph - the peristome - like a Nep. If not, you still get the idea ...
