Matucana haynei

This is a large plant, about 15 inches tall. Every couple weeks it produces a flash of flowers like that, 30 to 50 blooms each time.

Echinocereus mojavensis 'inermis'

The 'unarmed' E. mojavensis comes from around four corners area,  Paradox mountains is one of the spots, and to me it feels like the right name for this plant home. It is very sculptural to my taste, and also fairly slow.

Rebutia pygmaea

Very variable species, mainly by flower color, it is one of the all time favorites. Small plants are forming clumps in culture, and often 15 cm / 6 in in diameter or more. This form has relatively large orange flowers.

Echinocereus coccineus hybrid

White-flowered E. coccineus hybrid, another picture from another season. The plant gets larger, and the flowering is more spectacular with every year.

Echinocereus mojavensis

This is a form of Echinocereus mojavensis from northern Arizona. It has somewhat darker flowers with pinkish tint in them, very noticeable when you see them next to the California plants that have more of orange in color.

Echinocereus nivosus

Long awaited flower of E. nivosus here. In literature this species is described as hard to flower. Here is a seedling of about 3 inches tall flowering for the first time. Apparently, all they need is plenty of sun. Not a big surprise when you talk about Echinocereus.

Lobivia formosa kieslingii

IDing this plant was a challenge for me, and even after it finally reached the flowering size I could not quite get it.This is a form of well-known Soechrensia, but it flowers not from the apex as you would expect, but from the base like other 'regular' Lobivias. Flower size and shape is identical to other Soechrensias.

Soecherncia is the original generic name for those plants, now lumped to  Lobivia or even larger genus Echinopsis. This is high-altitude plants, getting fairly large in time.
