Re: Tales of extreme hardiness
This is my first Echinocereus triglochidiatus, purchased in 1984 in 6 cm pot, now in 30 cm pan. Triglochidiatus is not that fast growing in comparison with E. coccineus.

Re: Tales of extreme hardiness
Another very hardy Echinocereus is Ecer. triglochidiatus ssp. triglochidiatus. Here in Bohemia I never experienced any damage with this subspecies. The first picture is a robust ecotype orriginally from Tularosa Basin in NM. However now they are only slightly larger than normal triglochidiatus. The ...

Re: Mineral based compost
Based on my experience on habitats in Argentina and Chile, I can say that most of cacti grow much faster in habitats than in our pots. There are exceptions in extremely dry regions, say in Chile on coast north of La Serena or in Argentina in the desert of San Juan province. Certainly, cacti which ar...

Re: Mineral based compost
I have several Esc. hesterii for some 15 years and they are ok in fine sand with just a little bit of loam. Esc. hesterii is very frost hardy if dry, mines were many times bellow -20°C.

Re: Taxonony Eriosyce calderana/ E. talt. ssp. pygmaea
The book of Buining´s pictures looks great. Is it still available? Regarding Pyrrho. taltalensis, I believe Wendelin Maechler that it is plant with pink almost closed flower flowering in winter. I must say I have never seen such a plant. That is why I am rather reseved to put summer flowering plants...

Re: Tales of extreme hardiness
One of the hardiest echinocerei is Echinocereus inermis (E. triglochidiatus ssp. mojavensis fa. inermis). These are F1 from seeds sold by Horst Kuenzler in late 1960-ies. The seedlings were rather prone to damping off in the greenhouses but our chairman managed to graft two seedlings on Eriocereus j...

Re: Taxonony Eriosyce calderana/ E. talt. ssp. pygmaea
These are from seeds which I collected the next day at Punta Achurra, north of Chanaral. The Pyrrhocacti (5 in total) grew on gray volcanic rock while there were mumerous Copiapoa serpentisulcata on wheathered granite. I have identified them as Pyrrhocactus intermedius but I may be wrong so other su...

Re: Taxonony Eriosyce calderana/ E. talt. ssp. pygmaea
These are seedlings from seeds that I have collected just accross Panamericana from the beach of Balneario Portofino. Nice to confirm my opinion that they are P. pulchellus. The head which bore the fruit was about half the current size of the seedlings.

Re: Welcome back Trichocereus and Lobivia!
I made many attempts to cross polinate my only flowering Trichocereus pachanoi with Tr. huascha, Tr. grandiflorus and Soehrensia bruchii. All but one attempt failed completely. Fruit was formed on Tr. pachanoi polinated with a giant type of T. grandiflorus from western slope of Sierra de Ambato. The...

Re: Pterocactus
Thanks for explanation, here in CZ we understand that caudex can be even a thickened root. You are right, thickened roots once planted exposed stop growing.
