Utricularia cornuta

Description

Utricularia cornuta is a very cool, delicate, carnivorous plant, almost invisible until the large, yellow and fragrant flowers (1-6), snapdragon-like, appear on brown stalks in somewhere in June-July (depending on the location).
They are very conspicuous, especially considering the lack of foliage.

The thread-like leaves of bladderworts are equipped with small bladders submerged in shallow water or the wet substrate and are used to catch various invertebrates. Each tiny bladder has a trap door surrounded by trigger hairs.

After the flowers fade, sometimes brown capsules containing very fine seeds are formed. It is even more difficult to spot the plants at this stage; even if they are usually growing in small colonies.

I have seen the Horned bladderwort growing by himself or with other carnivorous species like Drosera linearis, Drosera intermedia, Pinguicula vulgaris. It can be cultivated in the garden in an area with shallow water/a bog, pond margins….

Germination: the seeds are dust like – sow them directly on the surface of moist medium (preferably nutrient free, like peat+sand mix), place the pot in a plastic bag to retain high humidity and provide strong light. Open the bag once in a while and especially after you (hopefully) notice signs of germination.
I cannot find info for this particular species but apparently most Utricularia species do not need a cold period for germination, just surface sowing and light.
