Lophophora seedling pictures

One month ago I sowed most of my Lophophora seed for this season and thought I would post some pictures of the minuscule seedlings, only a couple of weeks old.

I again bought seeds originating from the L. williamsii population in El Oso, Coahuila as I'm fascinated with the plants described in the booklet The genus Lophophora – Kaktusy Special 2, 2005 - allegedly this variety forms massive clusters with individual heads measuring up to 15 cm in diameter. The two seedlings in the center front of the above photo have grown from the same seed.

For a long time I have wanted to grow the Lophophora decipiens offered in the Mesa Garden seed catalog – the plants are alluringly described as “powdery grey”. I have started L. decipiens seeds from Mesa Garden once before but ended up killing off most of the seedlings – to be on the safe side I ordered 100 seeds this time and are going to start them in several, separate batches ;-)

I'm growing increasingly enchanted with Lophophora fricii but don't really have any mature specimens of this interesting species (except one plant that is almost of flowering size). To amend this I'm starting batches of Lophophora fricii from seed on a regular basis.

The L. williamsii plants from Presidio County, Texas represent the northernmost form of L. williamsii, also known as Lophophora williamsii var. echinata, and is a self-evident candidate for growing in the coldhouse.

Lophophora diffusa swelling with water, time-lapse video

I'm keeping my plants completely dry during their winter dormancy and consequently they are rather flaccid come spring. The following time-lapse video shows a couple of my larger Lophophora diffusa plants growing turgid after having their first drink of water in several months.

It seems like the movie couldn't be embedded - you can watch it at http://www.youtube.com/v/4aszzRMRPs0&hl=en&fs=1

In a fit of thoughtlessness I also watered the Bowiea volubilis visible in the background. This plant also started to expand generating visual “noise” that makes it harder to see exactly what moves when and where. To amend this mistake I inserted the white markers that act as fixpoints showing how much the cactus will have expanded by the time the video ends.

The pictures used for the time-lapse video were taken over a period of 88 hours starting March 6, 2009 in the afternoon through March 10 in the morning. A picture was taken every 15 minuttes giving a total of 352 photos; these are played back at 24 frames per second resulting in a video lasting slightly less than 15 seconds. Another piece of technical trivia is that each second of the time-lapse video corresponds to 6 hours real-time.

The pictures used for the high-definition (1280x720) version of the video above were cropped to obtain the 16:9 aspect ratio. A time-lapse video based on the uncropped and unmanipulated photos (without white markers) is shown below.

The swelling of the plants is not as evident as I had hoped for so I might try doing another “swelling with water” time-lapse video again next year – this time starring some of the plants from my coldhouse (as they are drought dormant for a longer time than my windowsill grown plants). Also the flickering, caused by the shifting light conditions during the day, is a bit disturbing. If I do a video like this again I'll see if I can avoid ambient light completely.

The Barcelona Cactus Garden – Jardins de Mossèn Costa i Llobera

As mentioned in the previous post I recently spent some time in Barcelona, Spain.

I had been looking especially forward to visiting the cactus garden, Jardins de Mossèn Costa i Llobera, located on the steep slopes of Mount Montjuïc that face the Mediterranean Sea and overlooked by the Montjuïc Castle (its hard to beat a location like that!), but when we arrived at the garden it was closed. We checked various signs and posters that all claimed that the garden should have opened a couple of hours prior to our arrival but all gates were locked. While I was standing sulking and disgruntled my entrepreneurial girlfriend had scanned the area and located a hole in the fence and through we went;-)

It was a great experience wandering around the deserted garden – at first we lurked about, halfway expecting to be thrown out any minute, but nothing happened and soon we just enjoyed this calm and secluded cactus haven located so close to the hustle and bustle of the city.

We never found an explanation for why the park was closed. Most of the park looked well tended for and ready to receive visitors but some of the more remote areas of the park had entered into a state of “lush decay” and a few foot paths were even blocked by plants.

Later, when visiting Montjuïc Castle, I noticed a jogger crossing the cactus garden down below and leaving it through a different hole in the fence. Maybe the holes are an unofficial way of keeping a closed park open ;-)

If you're in Barcelona the park is definitely worth a visit – if you can find a way in ;-)

The video above shows a panoramic view of the central bed of the Barcelona Cactus Garden, Jardins de Mossèn Costa i Llobera. The bed features a group of massive Echinocactus grusonii (Golden Barrel Cactus) in the foreground - I have seen these described elsewhere as "clusters of round cactus that resemble a colony of alien eggs just about to hatch" ;-)

The Botanical Garden of Barcelona – El Jardí Botànic de Barcelona

I spent the last week of April vacationing in Barcelona, Spain and of course had to visit the botanical garden (even though I later had to spend hours and hours shopping and browsing shoe stores to be granted indulgence for spending a day among plants on Mount Montjuïc ;-)

The botanical garden of Barcelona was opened on April 18, 1999 so most of the plants are still quite young – the garden is worth a visit today but has the potential to become an absolutely amazing garden in a generation or two when the plants mature. The main focus is on plants from the Mediterranean climate regions (the homoclimatic zones of California, Chile, the Mediterranean basin, South Africa, and Southern Australia) so cacti are not predominant.

Still you can find lots of interesting succulents like the stand of Beschorneria yuccoides (Mexican Lily, Red-hot poker), a stemless plant with an impressive bright red inflorescence ranging from 1 to 1.8 meter long.

Speaking of fantastic inflorescences I also have to mention the Furcraea bedinghausii that flowered during our visit.

The garden is situated next to the stadium, Estadi Olímpic de Montjuïc, that generates a lot of noise when a game is on. It was a slightly weird experience when the peaceful garden suddenly buzzed with the singing and shouting from the stadium.

Actually two botanical gardens are located on Montjuïc. The construction work done in relation with the Olympic facilities built in 1986 seriously affected the stability of the Historic Botanical Garden and it was decided to build a new one (the one we visited). We tried to locate the historic garden, without luck (it was said to be located on the opposite side of the stadium from the new garden, but we couldn't locate it with certainty... we found what looked like an old park on some extremely steep slopes, though).

You can read more about the Botanical Garden of Barcelona at their website. If in Barcelona, make sure to also visit the Cactus Garden, Jardins de Mossèn Costa i Llobera.
