Drosera indica is found in Africa, Australia, India (the
name indica is derived from India). The plant is naturally found
along ephemeral creeks on sandy soil and in seasonal swamps. Forms vary mostly in plant
and flower color. Plants can be green or red, and flowers may be
either white, pink, or orange. Drosera hartmeyerorum is like a red plant,
pink flowered D. indica. The only difference is found in the "runway lights" on D. hartmeyerorum. Both species have
the same culture requirements.
Drosera indica is an annual which means under normal circumstances
within one growing season it will grow quickly, bloom, set seed
and die. In nature the seeds sprout with the onset of the summer
rainy season. It requires very warm and bright conditions to do
well. The plants bloom and then die in the fall as the ground dries
Drosera indica unlike most sundews does not seem to do
well in the regular sopping wet peat mix. A soil mix of mostly
or even complete sand works best. Some people have told of success
using an airy mix of peat and perlite. Sow the seeds on the surface
and put the pot in a very warm and bright location. I put pots
with seeds in a sunny windowsill or close to florescent lights.
A temperature about 25°C (80°F) works best. This sundew prefers
drier soil. You can allow the pots to go dry between waterings.
The seedlings may be a little slow growing at first but they are
definitely faster than most Drosera species.
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 rehydrated in water or milk and placed on the
dewy leaves—don't feed a plant that isn't dewy. Use the leftover
milk on your butterworts.
Drosera indica never reproduces from root or leaf cuttings.
You may prolong its life by cutting the top off and re-rooting.
This does not always produce a healthy plant. It is best to start
over again from seed. The plant is a strict annual and will die
after setting seed. When you grow them you should always be thinking
about getting enough seeds to make sure you will have the plants
again next year.
