Cuttings rooted on H2O. Took 2 months to develop roots of 2 to 5 cm. These are Eurphorbia resinifera but also other Euphorbia species root well in water. Ideal temperature is around 20 degrees Celcius (=68 F). Just started an experiment with 2 Lophocereus species. Keep you updated.
The reason for this experiment is that there is an overseas demand for this rooted plant material and as it’s a regulation that no soil particle is allowed to leave the country.. (etc. etc.). At this stage we are rooting a few hundred Euphorbia cuttings (diverse species) in water.
We are no scientists (just make use of them) but we like to experiment and prefer to choose for the most unlikable things. Sometimes we succeed, sometimes not but when you never try you will never know.

Most beautiful in Winter because the impressive caudex is uncovered by leaves of this Southern African caudiciform with a diametre of up to 35 cm. Locally it is also named ‘Bobbejaansgif’ (Afrikaans for baboon’s poison) for its high content of toxic sap (cyanogenic compounds). The genius Adenia (21 species) belongs to the family of the Passifloraceae. The specie A. fruticosa was first described in 1926 by Joseph Burtt Davy. The Adenias fruticosa and glauca are the best known species and grown relatively easy provided the right environment. It’s also suitable for cultivation in a container and is drougth tolerant but likes some extra water in Summer when in leaf. Hardiness: Zone 10a to 11 with minimum temperatur of minus 1 degree Celcius (30F). Well drained gritty loamy soil. Do not fertilise!!! The plant in the picture is grown from seed (2004) and resisted this year 5 months of no rainfall here at The Green Cathedral of South Africa.
Every now and than we shoot in the garden; not with a shotgun but with a digital camera. Here 5 pics; one shows a part of the garden (totalling 11,000sqm and over 2500 different succulent plants outdoor); one showing an elephants foot (Dioscera elephantipes); one with a fruiting Pilosocereus lanuginosus; the fourth is a Adenium arabicum with flowers AND seedpods and the last is an overview of our retail nursery. It’s not all succulent here in The Green Cathedral of South Africa but that’s for you to find out; preferable on the spot where you can feel, touch, smell, hear and see.
