Ugh, it's way too slow at the moment, but my favorite Nepenthes in my possession is my N. burbidgeae. I love the red stripes on the cream peristome, the blocky splotches inside the pitchers, and the purplish tinge that sometimes outline certain features of the pitchers, and I'm surprised to be able to see all that with such distinctness in a plant barely ten inches across, with about 2.5 inch pitchers. Hopefully it will speed up as things get cooler in the next few months, but for now, it's holding up quite nicely sitting on my windowsill.
