The Asclepiadaceae family: African succulents with beautiful but… smelly flowers

Although more than twenty years have passed, I still remember my first encounter with an Asclepiadaceae. A few years ago, I approached the world of succulents, and I went to visit a nursery just outside my city. I had been browsing among the succulents for quite a while when the owner of the nursery, an elderly but very chirpy lady, noticed me and my interests in plants, approached me and said: “Do you want to see a succulent plant with beautiful flowers?” I said yes, of course, I wanted to see it, so she took me down a narrow corridor cluttered with plants and pointed to a large succulent in a hanging pot. It had thick fleshy, straight green stems with reddish edges, and from one of these stems hung a big star-shaped flower with elongated, thin tips and shaded yellow petals crossed by tiny dark streaks. “Come closer, sniff how good it smells”, the lady said to me, passing from a restrained smile to an open, fat laugh, as soon as I obeyed and immediately withdrew, disgusted by the smell of rotting flesh that from that flower had entered right into my nose.

Crassula ovata, “Jade Tree” or “Money Plant”: here’s how to grow this beautiful succulent

Commonly known as the “jade tree” due to the bright green color of its fleshy leaves, or the “money plant” due to the roundish/elongated shape of the leaves, Crassula ovata is a very common succulent plant in cultivation. It can also often be observed in apartments, where it grows well thanks to its great adaptability and where it can add an unexpected touch of green thanks to its sapling habit, with thick and robust brown branches. Crassula ovata is certainly a common plant, not at all sophisticated, and simple in its forms; however, it has its own charm and the ease of cultivation makes it a succulent practically within everyone’s reach.

In the following article we see in detail where it comes from, what are the cultivation needs of this succulent, what are its weaknesses and how it can be successfully reproduced even by those who are beginners in the cultivation of succulent plants. (…)

Echinocactus texensis, an in-depth study of the “horse crippler”

The following is an in-depth article on the Echinocactus texensis species that I wrote some time ago and which, with my great pleasure, was published in the Cactus World magazine, published by the British Cactus & Succulents Society (BCSS). My thanks to editor Al Laius for the publication in the prestigious magazine. (…)

Repotting cacti: an experiment with different substrates to understand how potting soil affects growth

The fundamental factors for the growth of a plant are many: from exposure to watering; from fertilizations to temperatures. Among these factors, one of the most important – at least for cacti and succulent plants – is the substrate. The ideal soil for cacti must have at least two properties: it drains well and it dries quickly. (…)

Six identical cacti in three different soils: a cultivation test with Mammillaria hahniana

Here is another test of mine. In the cultivation of cacti, a bit like with many other passions in life, there are two different approaches: a “static” approach, let’s say “contemplative” and “collecting”, and a “dynamic” one, experimental and inspired by an ever greater understanding of these plants. In this second approach (which is the one that has inspired my passion for years) the study of reliable texts, the comparison with other growers and, above all, the experimentation in the field, for example, working on potting media, exposure, cultivation techniques and more, are fundamental. Just growing plants – succulent or not – for years and years, in the same way, never changing the type of soil, exposure or method of cultivation is fine, mind you. Clearly, it’s perfect for those who only appreciate plants from an aesthetic or collecting point of view and have no particular demands. In short, it’s valid for those who are not interested in learning more and are not willing to take risks to improve and better understand the plants themselves.

Instead, the aim of “wild” cultivation is to obtain specimens as robust as possible, and with the same look to those that grow in the habitat (I write about this cultivation’s philosophy here). In addition to the documentation and possibly travel to observe the plants in nature, it is essential to engage in some experiments and be willing to question continuously, even if it could lose some specimens (not the valuable ones, of course).
