FLOWERING TURBNICARPUS MIX PACKAGE OF 20 SEEDS of different variety of Turbinicarpus, the picture is only to give an idea of the plants used to collect seeds but I have a lot more not showing in this picture, this is a MIX and will shipping as mix not independent labeled by species, the seeds were took this season, We have a lot of extremely rare cactus if you want something rare let me know and I will listing for you. Questions? feel free to email me. These cactus grow mostly on limestone soil, at altitudes between 300 and 3300 meters above sea level. Turbinicarpus are usually confined to specific habitats, generally hostile for the majority of plants, mostly in very drained rocky areas, composed of limestone, sandstone, schist (neutral or alkaline), or in very acidic and humiferous underwood, or in gypsum veins, sometimes so pure that is almost white. In particular, Turbinicarpus strictu sensu are adapted to extreme niches: more than 80% of the species grow in rock cracks or among the pebbles beneath them, where enough dust accumulated to enable root development. It would seem almost impossible that plants so small could survive in such an environment, however in those species that inhabit dry and exposed areas, the root is very thick, becoming a taproot and acting like an anchor on the slopes but, more important, as a water storage for the dry periods, capable of significantly retracting into the ground so that the stem is less exposed to the sun; the spines are often changed to adopt a very papery structure, capable of absorbing good quantities of water. Furthermore, the general look is extremely mimetic, thanks to the epidermis colour and the interlacing spines, guaranteeing a certain protection from eventual herbivores.
