             Three (more) first-timers                     Trevor Wray       

I wrote an article for NN on three plants that flowered for the first time way back in 1991. Obviously since then there have been many more though mostly of the kind that would not cause great excitement here. After all, when you buy a plant of the Rebutia group you expect it to flower every Spring. A Mammillaria that didn’t perform would be out on its ear!

Opuntia articulata 'diademata

The first of this group is a plant I have labelled as Opuntia diademata and before I could write about this I had a problem. When I reached for my CITES checklist the species wasn’t listed. How could I check the spelling and see if this was a currently accepted name? Same in the New Lexicon. Strange, very strange…

Luckily I have been a contributor to Bradleya for the last 25 years (happy birthday!) and luckily Roy Mottram and Richard Crook wrote an Index of all the names that were vaguely connected with Opuntia. Not the most exciting read (unless you have insomnia) but a useful reference. I reached for the C to D episode of 1996. ”See articulata diademata”.

I reached for the A to Bs of 1995. It seems Lemaire described Opuntia diademata in 1838, then reclassified it as a Tephrocactus in 1868, (when the ending changed to ‘–us’). This was a name with some history; I should never look again at that plant without great respect! Backeberg changed it to a variety of T. articulatus in 1953. Then Kiesling referred the plant to Opuntia articulata var. oligacantha and at least the articulata was in the CITES checklist. I will naturally keep the label O. diademata on my plant.

So, back to flowers. I acquired Opuntia diademata as a single joint a dozen years ago. I was aware that it was of the Tephrocactus persuasion so wasn’t expecting flowers. These days I know that many of this kind flower as regularly as my Rebutias. The joint filled out and after a bit, each year it grew just one new one on top. Looking decided wobbly I placed some canes to support the stem. Then in July it flowered from the second from top joint. It was a complete surprise, the bud had developed round the far side. I never got to see the flower fully open, (working days and dismal weather), so the picture is the best I can do. Looks like a Tephrocactus articulatus flower? Oh, all right. Bad news was that moving the plant for the photographic record snapped the stem near the base, good news is I will be able to propagate this novelty from cuttings.

Oreocereus trollii

My second contender is a plant of Oreocereus trollii I have had for over thirty years. It is a nice clone with lots of wool and stout red nails poking out. Years ago the central head was looking rather tired and I cut it out to grow on three offsets. A fourth offset was rooted and potted separately. Neither of these plants have flowered before. I was amazed when I saw there were three buds at the apex of one of the stems and followed the development with some interest. 

Oreocereus trollii

Over a few days I was able to take some reasonable pictures. All cacti eventually reach a size or maturity to flower but whether this is a one-off due to last year’s exceptional weather or I will have a repeat performance every year, only time will tell. 

My problem as I write this is our annual show is a fortnight away and should I remove the spent flowers from the plant? Or leave them there to proudly say, ‘I did it, I flowered an Oreocereus at last!

My final offering is very different from the previous and not just because it is one of the other succulents. Echeveria nodulosa is a common plant that is easy to grow but only recently acquired here. It came, un-named, at a stall in the ‘Garden Open Day’ scheme and was a quid for charity well spent. It wasn’t worth two quid because it was crawling with mealies. A squirt of Imidacloprid, (Provado to you), between the eyes soon dealt with that! I thought it would have some merit as a summer patio plant with the Mexican Sedums.

Echeveria nodulosa

I noticed the early development of flowers and watched the stem extend. Some Echeverias have attractive flowers but I wasn’t sure what I was going to see with this one. Well, as a spectacle it was a bit of a disappointment but a close look at the individual flowers show that they are rather fancy. After a look at Walther’s ‘Echeverias’ an even closer look at the flowers with a hand-lens showed that, yes, they were minutely papillose (posh word for having nipple-like growths). In fact all parts of this species have papillae. Having snapped the pictures I snapped the flower stems off. OK… they are OK, but not that OK. Nodulosa ought to concentrate on growing some more of those really attractive leaves.

 

P.S. The problem of the spent flowers on my Oreocereus solved itself; shortly a fruit developed so I could hardly pull that off.

Echeveria 'Frank Reinhelt          Trevor Wray

Echeveria lindsayana X agavoides I first met Echeveria ‘Frank Reinhelt’ at a Birmingham Show and I was impressed. It was a single-headed, green plant suffused through with red and obviously had a lot to do with Echeveria agavoides. Shortly after I bought a plant named Echeveria agavoides x lindsayana which had to be the same hybrid. Both parents are attractive species and the mix had the same red coloration I admired.

E. ‘Frank Reinhelt’ was introduced as ISI 1467 in 1984. The official parents of the cross were then given as E. agavoides var. prolifera and E. colorata (the present ‘correct’ name for E. lindsayana.) From the internet I learnt that E. ‘Frank Reinhelt’ was awarded an Award of Merit by the RHS in 1993 along with several other species and cultivars. Frank Reinhelt himself was an Echeveria hybridiser of Capitola, California who also introduced ‘Black Prince’. There is an attractive Graptopetalum ‘Frank Reinhelt’ as well.

E. ‘Frank Reinhelt’ is not a common plant around our parts. It does not branch quickly and when I tried a few leaves they rotted while I looked at them. Many Echeverias will grow from the detached leaves on the flowering stem so I will try these. Meanwhile I was pleased to see some plants for sale at B&Q just before last Christmas. Like mine they had the intense red that develops especially in autumn and winter, though these were even better. What extra light intensity could they manage in Holland? (Or China?) But then I looked again, it wasn’t quite the ‘plastic cactus’ or the ‘Helichrysum flowers’, but the red colour we admire had been sprayed on. This was a fraud! Will the customer who buys a red Christmas decoration discard it in the New Year when new growth on a windowsill is apple-green? Will the Trading Standards people pounce? I don’t know, but properly grown Echeveria ‘Frank Reinhelt’ is a delight.
