This is my very first picture of U. sp. “Hermanus” flower. A few weeks ago I asked you what should I do to see its flowers, and shortly after I noticed a few flower stalks emerging from above stolons.
On that occasion I enclose also picture of the whole plant. As you can see the stolons (above soil level) are very long, some have about 3 cm (notice nice red coloration of their tips). I keep it on windowsill of south-west window. The pot stay constantly in 1 cm water.
I’m not sure what factor make it flower, but maybe temperature is the clue. In winter my plant had average about 15 C. I also think that “Hermanus” needs lots, lots of light. Production of flower stalk and then opening of the flower bud was extremely slow, maybe due to very rainy weather we had here for the past three weeks. When the first “Hermaus” stalk was half its size, my U. parthenopipes started to form the one on its own and guess who flowered first.
