Saintpaulia - African Violets

African violets, Saintpaulia were perhaps the first plants that I was fascinated with. There is this picture of me at around four or five holding one and beaming ecstatically. Strangely in the past whenever I tried growing them they only lasted a few weeks before dying either from over watering or lack of watering. Due to this I considered it one of the few plants that I could not grow which is weird since they are supposed to be easy to care for. Although I have heard from some people that many people are unable to keep them alive for longer than their flowering period.

So I have been quite delight that my streak of bad luck with African Violets appears to have ended. I bought one (above) several months ago and after it survived several weeks I bought three more. I was hoping to get more colours because I wanted to be able to show the wide range of colours and shapes of these beautiful plants. Here (below) are the four plants that I got.
Since then two have grown significantly. Last week I transplanted those two into bigger pots and have been contemplating transplanting the other two even though their size does not really justify that. I am also going to see if I can propagate some from leaf cuttings, with the intention of doing a post on that since I have not done any propagation posts for a while.


I still hope to be able to get some more colours eventually. However, I may end up simply asking if I can take some photos since my room is kind of running out of space to put plants, and with fussy plants I have come to the conclusion that once I have found a place that a plant likes I should just leave it where it is happy.

I also find that if there is the likelihood of others interacting with the plants they tend to die or suffer although this is more due to accidental, unconscious actions and even well meaning acts that are detrimental so depending on where I am living that can limit what I can have and where I can place my plants. For example I have been thinking of putting some of my plants in the living-room/kitchen but am waiting for spring when I will be sure that use of the heaters will have ended since the heaters are under the windows and the only suitable place to place the plants, not to mention being out of the way from people accidentally bumping them or stepping on them if I put them on the floor.

Among the colours I'm hoping to find are white, pink and some doubles as well as yellow which I was told does not exist although I have seen yellow cultivars advertised on some sites and collections. That appears to be either new and/or rare.

Thunbergia alata - Black-eyed Susan vine



Thunbergia alata otherwise known in English as Black-eyed Susan is often seen in some parts of the world as a vine that grows on fences or over other plants. It is sometimes considered a weed despite its striking flowers for which it is cultivated and prized for by some gardeners who grow it on trellises or as a green screen for privacy.

The genus Thunbergia is named in honour of the 18th century Swedish botanist Carl Peter Thunberg.

Carnivrous Plants: Pinguicula moranensis

Pinguicula moranensis commonly known as Butterwort is a carnivorous plants which is native to Mexico and Guatemala. It succulent leaves are covered in pednucular (stalked) mucilaginous (sticky) glands which help it to attract and trap arthropods (invertebrate animals with exoskeletons) which it then digests with the sesile (flat) glands. The pednucular glands secrete a sticky substance which appears like droplets of water on the leaf. When an arthropod (mainly insects) touched the pednucular gland it releases more of the sticky substance and when the insect struggles to free itself it triggers other nearby glands to release more until it is encased in it.

The leaf can bend itself slightly through thigmotropism to bring more glands into contact with the prey. Once the prey is entrapped the sesile glands release digestive enzymes which to digest the prey breaking down the digestible parts of its body into liquids which are then reabsorbed by the leaf through cuticular holes leaving only the chitin exoskeleton behind.

The etymology of the genus name Pinguicula comes from the Latin pinguis which mean fat because of the buttery texture of the leaves while the specific name moranensis refers to its type location, Mina de Moran in the Sierra de Pachuca. This is where the three botanists Humbolt, Bonpland and Kunth collected specimens of the plant during an expedition in early 1800s. However, in 1999 a Mexican botanist S. Zamudio collected specimens in the same area and noted that the plants he had collected did not share the original description given by Humbolt, Bonpland and Kunt
Further investigation based on the travels of the earlier expedition led Zamudio to conclude that the plants collected by Humbolt, Bonpland and Kunt were most likely from an area called "El Puente de la Madre de Dios" in the Mexican state of Higaldo. He confirmed this by finding matching specimens of the plants in that area.
So it appears that due to some mix up these plants were misnamed. In the end Zamudio published his findings as a variation of  Pinguicula moranensis under the name Pinguicula moranensis var. neovolcanica.
