Drosera dielsiana x nidiformis. This plant is 4cm
across.

Drosera dielsiana x nidiformis is a hybrid between two
Drosera species found in southern Africa. It has also been listed on the
seed bank as D. x snyderi. The small plant makes a good
addition to any terrarium but is difficult to maintain long-term.
Drosera dielsiana x nidiformis isn't very picky about soil.
It grows best in the standard 1:1 peat:sand "CP mix".
The plant is very susceptible to a fungus that causes the plant to turn
all red and loose it's dew. A systemic fungicide such as Clearies 3336
can be effective unless the fungus becomes resistant from spraying too
often. Do not use fungicide on a regular basis as that results in selecting
for resistance. If this happens, use dusting sulfur.
Sow seeds of Drosera dielsiana x nidiformis on the surface
of your medium of choice. Finely chopped live sphagnum moss over CP mix
works very well but the moss can overgrow the plants. Finely chopped dead
sphagnum or sand over CP mix also works well.
What you do next depends on what works best for you. Everyone has their
own preferred routine. I put pots with seeds in plastic zip-lock bags
under but not too close to florescent lights. A temperature between 20C
to 25C (70F to 80F) works best. When the seeds begin to germinate, I remove
the pots from the plastic bags and move the pots to a bright location
slightly drier that gets a little air circulation to help prevent damping
off. The seedlings may be a little slow growing at first. Have patience.
Because it is a hybrid, you may have a some variability in the plants.
Don't go to heroic efforts to save the smaller plants--they will always
be small.
Once the plants are large enough you can try feeding them small insects
or get some dried blood worms at a pet shop. The dried blood worms can
be dipped in water and placed on the dewy leaves--don't feed a plant that
isn't dewy. If the food gets moldy, use less next time. A dab of 70% isopropanol
(rubbing alcohol) from a small paint brush will kill the fungus.
Drosera dielsiana x nidiformis tends to live a year or
so. It should be easily to propagate from root and leaf cuttings. When
it blooms, save the seeds to grow more. If you have lots of seed, send
the extra in to the seed bank.
