A Crested seedling in flower , this is one of the rarest and priced crested cacti,
sought after by collectors but rarely on the trade.

 

Description: The standard T. alonsoi is a small geophytic solitary cactus with a large tap-root, and only the apical part of the stem exposed at soil level. The crested form here described is one of the rarest and priced crested cacti,
sought after by collectors but rarely on the trade.
Ribs: Arranged in tubercles, these are 15 mm long and 13 mm wide at the base, slightly angular, upper side keeled, however concave at the base, clearly keeled on the underside, arranged in spirals,  from grey-green to glaucous in colour.
Areoles:  At first with reddish brown wool, later becoming grey.
Spines 3-5, up to 20 mm long, flattened, cardboard-like, grey with dark tip, irregularly bent inwards, frequently weathered, not piercing.
Flowers: Cherry red to pink-magenta, with more intensely coloured mid-stripe 20-30 mm in diameter, 25-35 mm long, standing above the tubercles by about 10 mm, with approximately 22 inner (teptals), scale like perianth segments, more intensely red with pale edge. Pistil 15 mm long, white, standing above the stamens by around 2-4 mm, with 6 white, 1.5-2 (-2.5) mm-long stigma lobes.
Blooming season: From March to October, mainly between April and June.

 

Cultivation: Robust species to cultivate. It requires full sun and careful watering to keep the plant compact and low. It has a tap root, and watering it properly is often difficult, because it tends to crack open or rot, if over-watered.

Propagation: by vegetative propagation grafting (usually) or stem cuttings.
