My collection

I’ve always been a bit of a collector, and in my childhood I went through everything from stamps, coins, bottle tops, bullets, to rocks and shells and everything in between. I was an avid collector of all these things, but it wasn’t until I discovered cacti that I finally landed on one single hobby (though I’m certainly not averse to collecting the odd rock or fossil!). I started collecting cacti when I was around 7 years old, helped along by a plant loving father.

I grew up in Kristiansand, Norway, and as it happens the local natural museum and botanical garden keeps one of the largest public succulent plant collections in Norway. We would often go there and look at the cacti and other succulents when I was little, and these trips certainly inspired me to keep collecting. Of particular note they keep a magnificent specimen of Echinocactus grusonii that is at least 350 years old.

My collection began as a number of random species without any Latin descriptions, bought partly from local flower shops and partly grown from seed mixes bought at the same stores. A sprinkling of plants from the above mentioned museum were the only ones with proper names. At that time it was all about buying whatever I could get my hands on (which my father would fund). In no time at all our glass veranda was filled up with cacti on the window sills and in wooden beds my father made that took up most of the floor space.

But, as so often happens to those who fall to that succulent spell, available space has a tendency to run out. And the immediate answer is, of course, never to adjust the collection to one’s available space, but to increase the available space so that one may increase one’s collection. And so on and so forth. We (I and my plants) were lucky enough to live in a big house with a big yard, so when I was 9 years old in 1992 I got my first greenhouse. At this point my father was very much invested in the hobby himself which was definitely a good thing since he is quite knowledgeable about most sorts of plants (and had infinitely more money than me).

We began sowing seeds in earnest which we harvested from our own plants. The flowers were far too tempting not to pollinate, preferably with as many other flowers as possible (never mind about hybridising). It was great fun to sow about a thousand Rebutia sp. or Gymnocalycium baldianum seeds – they all germinated so very willingly! We also bought seed from the local botanical garden and from the Nordic Cactus and Succulent Society. Some of these plants are still alive and well.

The greenhouse soon became a size too small at around 4 m2, and only a couple of years later, in 1995, I got my second greenhouse. A size up at close to 6 m2, it was all a twelve year old boy could wish for. At this point the collection grew steadily with plants bought from various nurseries in Europe and from seed bought from Europe and the US.

In the back: Leuchtenbergia principis.
The first one on the left in the front I’m not sure about. I think it may be Echinocereus subinermis.
Following this one: Astrophytum capricorne, Thelocactus bicolor var. schwarzii,
Hamatocactus sinuatus, Astrophytum myriostigma

Sometimes we went on holiday to our cabin in the mountains but the cacti didn’t schedule their flowering accordingly.
Naturally the only option was to bring some of them along!

Acanthocalycium thionanthum var. glaucum, Acanthocalycium thionanthum var. brevispinum, and probably Hamatocactus hamatacanthus in the back (1996).
(Note the insects exploring the new and exotic flowers.)

In my late teens I began finding less and less time for the plants on account of school and parties and all the things teenagers usually like to do. Then I left my home town to go to university and for many years I would only visit my plants a few times a year. When I finished university and got my first real job (in Oslo) I suddenly found I had an acute need to fill up the windowsill with cacti. Apparently my lack of regular close contact with the plants had left me very much dissatisfied with the state of things, and a cactus-filled windowsill simply wasn’t enough. So when my wife and I bought our first apartment a year ago, I immediately saw the potential in our spare bedroom and annexed it.

This bedroom has now become more or less the third greenhouse (if you discount the mini greenhouse on the balcony…). Light and heat is provided by two 400 W HID bulbs. All the plants are grown from seed sown over the past 14 months, and already many of them have flowered. I am continually amazed at how quickly it is possible to grow some of these plants when given more or less optimum conditions year round.

In fact, they grow so quickly that I’m dangerously close to running out of space…!

And on that note I will end this rather long entry. The next one will be about the hundreds of tiny squatters in the spare bedroom (or so I imagine my wife sees them).

First entry

Welcome to my blog about cacti and other succulents. My wife has finally managed to convince me to start a blog about my passion, and hopefully I’ll manage to update it regularly.

Though I certainly find many succulents fascinating and pretty, my main interest is cacti. Cacti are succulents too, of course, though for simplicity’s sake most people just call cacti cacti, and the rest of the world’s succulents are relegated to being called, well, succulents. At least, that’s how you’ll see it written on books and journals: e.g. “Cacti and other Succulents”, “Cacti and Succulent Journal” or, indeed, in the title of this blog. It’s only when one wishes to be a bit more specific that one might refer to groups of succulents as e.g. mesembs or euphorbias. Throughout this blog, then, whenever I mention succulents, I’ll usually be referring to succulents other than cacti.

Living rocks, the name of this blog, is the common name for several genera of succulent plants, though two genera in particular often go by that name. Those two genera are Ariocarpus and Lithops. The former is a genus belonging to the cacti family (Cactaceae), while the latter is a succulent belonging to the mesemb family (Aizoaceae). The former is found in Mexico and Texas, while the latter is found in South Africa, Namibia and Botswana. There is also another living creature that goes by this moniker, Pyura chilensis, but as it belongs to the kingdom Animalia it will not feature here. (I encourage everyone to google the creature, though! Who needs sci-fi when you can find creatures like this right here on Earth?).

Ariocarpus is my favorite genus of cacti, and Lithops is one of my favorite “other” succulent genera. Thus, the name of the blog seemed very fitting. So while this blog will mainly deal with cacti, I will definitely be writing about succulents too (and maybe one or two non-succulent plants as well).

In addition to writing about my cacti and succulents and about my own experiences growing them, I will also write about various topics from soil composition and watering, to additives and fertilisers, to literature on succulents and more. If there is any particular topic you’d like me to write about be sure to let me know.

This will be it for my first post. As I have just started out on this project, the blog is naturally a bit barren, but I hope to remedy this over the coming weeks.
