Hello all, So I started a colony of Darlingtonia "Mountain form" seeds a while back, and decided to make a thread about one of them in particular, since I finally have the first mature leaf forming! A picture below of when I first found it: As it grows out, I'll post more pics, but it's amazing just how different these mature leaves look even when just starting to grow out... ~hcarlton
Im curious how old were these plants when the photos were taken? The plants look nice and healthy. Are they growing in live sphagnum? I have some seedlings started and have learned that they seem to be very very slow growers.
They are rather slow growers, these plants were well over a year old at the time the photos were taken and are now approaching 2 years without a lot of size increase. There is live sphagnum on the soil surface, but the main soil is dead LFS and perlite.
The cobras I started are obviously not in optimal growing conditions when compared to yours. Mine are much smaller really never change in size.
I just placed some more seed in the fridge to be stratified for sowing in October. Will have to try something different but not sure what exactly. Mine were planted in a mix containing too much peat therefore the soil is not too breathable. This will have to be changed for the next batch to be planted. Im not sure what to do about the light levels and watering. What do you do for light and watering?
My seeds were started under some fluorescent lighting which turned the plants a fairly deep red early on so this could indicate lighting being too intense and may have stunned the growth somewhat. For watering mine sat in a shallow tray of water most of the time.
Did you sow your seeds on the top layer of live sphagnum or was it added later after the seeds sprouted? What temperature are they kept around? Do you use artificial lighting? Tell me more please as those are very nice looking plants!
Deep reds mean your plants are getting very good lighting. Remember, they experience full sun in the wild. Mine are under actually rather dim artificial lighting right now, I hope to move them to somewhere brighter eventually, and I hand water from the top every other day. The pot has holes all around the side, so they're always aerated too. As for the sphagnum, I neither added it nor were the seeds planted in it. It sprouted on its own sometime after the plants germinated.
