Matucana aurantiaca 'pallarensis'

Matucana pallarensis is a form of wide spread M.aurantiaca, a large growing Matucana. This plant I have is about 6in/15cm in diameter and has started becoming short-cylindrical. It blooms sporadically year around, responding to cooler spells in the summer and warmer days in winter.

Oroya borchersii

Oroya borchersii is a high mountain plant from Peru where it grows at altitudes above 4000m. Oroyas are straightforward in culture, but do not like high temperatures much. Cooler springs would result in more reliable flowering.
This plant developed buds in early fall, responding to the end of summer cool down.

Sulcorebutia steinbachii

Sulcorebutia steinbachii is a variable species, both in spines and flower color. Many Sulcorebutia names are actually treated as forms of that species. Relatively small flowers pink or red or yellow - are easily produced.

Ferocactus emoryi ssp. rectispinus

Ferocactus rectispinus is known for its fierce spines, longest of all Ferocacti - up to 25cm/10in long. The plant in picture has a size of a soccer ball.

Cleistocactus winteri

Cleistocactus winteri AKA Hildewintera aureispina is a common hanging basket plant, favored for it's golden stems. Nice orange flowers is a great bonus. Wide open flower was the reason this species was not recognized as CLeistocactus, but in all it is a very close relative and should be included into this genus
The plant in picture grows in Stanford Arizona Garden, planted in the ground.

Eriosyce subgibbosa

Eriosyce subgibbosa JA126 is in bloom again. The seedlings getting bigger, larger pot is long overdue.
