Ceropegia sp. ‘Tanzania, 10 km W of Arusha’

Ceropegia sp. ‘Tanzania, 10 km W of Arusha’

This is not my plant, I was asked to identify it – but unfortunately I can’t.

It may be identical with my Ceropegia sp. ‘Babati’.

The sixth new addition in 2011

The sixth new addition in 2011

Today I received two plants (Ceropegia arabica var. arabica and Ceropegia zeyheri) from Mr. R. from Germany.

They are in an extremely healthy condition, having unbelievable strong roots, so I needed to use the largest pots I could find.

Anyway, they’re doing fine, and I hope to see the first flowers soon, maybe already this year. 😛

A mysteryious plant – Ceropegia radicans ssp. smithii

A mysteryious plant – Ceropegia radicans ssp. smithii

It was always an irrevocably fact to me that this form is nothing but an naturally occuring hybrid of Ceropegia radicans and Ceropegia sandersonii, as both species are well known to hybridize readily with each other in cultivation – and in fact there are several such forms to be found under a clutter of names.

It was ….

There are many botanists who accept this plant as a subspecies (or variety) of Ceropegia radicans.

According to the original description the two subspecies of Ceropegia radicans are neither geographically nor ecologically isolated, that means, both occur in the same region, and even share the same habitat (the valley of the Kwelega River in the East London District of South Africa’s Eastern Cape Province).

They are said to differ from each other by the shape of the flower, whose lobes form a cage-like (in the ssp. smithii) resp. a narrowly pyramidal structure (in the ssp. radicans).


In the year 1911, P. Roth reported in “Die Gartenwelt” the first (documented) artificially produced hybrid of two Ceropegia species.:

“Eine künstliche Kreuzung, C. sandersonii, befruchtet mit Pollen von C. radicans, hatte jedoch Erfolg. Dies ist die erste erfolgreiche beabsichtigte Kreuzung bei Ceropegien.”


“An artificial crossing, C. sandersonii, pollinated with pollen of C. radicans, yet was successful. This is the first successful intended crossing among Ceropegias.”

There are many such hybrids to be found in the trade today, some go by names like “Apollo”, “Jupiter” or “Mars”, and they mostly are very similar to Ceropegia sandersonii, or even much more so to the plant that we now want to call Ceropegia radicans ssp. smithii, respectively.


Whatever now the truth may be – the plant shown on the photograph goes back to material that was collected (around 1985) in the wild!

The photograph shows a plant that can be traced back to collections made by P. V. Bruyns himself – this is its ‘field number’: PVB 2162, Blue Water Police Station, Kwelegha River, E. London, RSA.

The fifth new addition in 2011

The fifth new addition in 2011

I know, I deserve to be kicked in my ass … but I was in ‘that’ nursery again ….

The newest additions to my collection are named as Ceropegia linearis ssp. debilis (I will talk about this particular plant later) Ceropegia inornata (of which I already have two plants – so I have no idea why I bought another one :-() and Ceropegia radicans.

Ceropegia arnottiana – a new species from Thailand in the German trade

Ceropegia arnottiana – a new species from Thailand in the German trade

Remember the (possibly) new species from Thailand, which appeared in the German trade?

Well, this is its flower, a very impressive one.

But still the question remains – which species is this?

Well, according to the website of Apodagis it may be Ceropegia arnottiana.

This is now identified as Ceropegia arnottiana.
