Does anybody know about how fast (increase in size, to maturity) the following nepenthes grow:
N. lowii x truncata (does this increase in size as fast as truncata, or more like lowii?)
N. ephippiata (how long until I start to see uppers on a 9" plant?)
N. burbidgeae (if I have a 10" plant, how long til it starts to make really big lower pitchers, and starts vining?)
Your probably wondering why I'm asking all this, but I'll tell later [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img] . Thanks.
Hmmm, difficult questions, grasshopper.
Lowii x truncata I've found slow, but admittedly I am in the middle of winter here. It grows at much the same pace as my lowii.
Ephippiata, somewhat like lowii, can produce uppers quite suddenly once mature. A plant of the size you mentioned might be a year or two away from produing uppers. It is a slightly faster grower than lowii.
Sibuyanensis I've found a steady grower, it won't break any records, but will plod along quite happily in the rights conditions. Mine took about 3 years from a 5" plant to flower.
Burbidgeae is a funny one. It has bursts. It will grow at a glacial pace for a while, then have a sudden burst where it will produce much larger leaves, then plod on for a while etc. As a rosette plant it will generally be slow, but when it starts to climb, it can be remarkably rapid.
