Thelocactus being a synonym for Hamatocactus and Thelomastus is a genus in the cactus family, Cactaceae. Members of the genus are native to the arid lands of Central and Northern Mexico. Thelocactus species are globe-shaped, short and cylindrical. They are small cacti, although there are one or two species which, while only about 15 cm high, can be 25 cm in diameter; for example, Thelocactus nidulans. Thelocactus species are generally solitary, but some varieties will cluster in groups. Thelocactus species grow in the wild in central and North Mexico but also on the other (northern) side of the Rio Grande, in Texas. Species can be distinguished by where they grow, whether in mountainous stony/rocky places or grassy territory with clay soil. Thelocactus species are generally easy to cultivate. Soils should be composed of equal proportions of sand and humus.            Water them normally from spring to autumn. In winter, keep most species at a minimum temperature of 8°C. They can survive at lower temperatures but the roots must then be kept dry. The dark brown or black seeds can be relatively large for the size of cactus and they germinate readily. They are well suited for growing in pots and rockeries. Reproduction is nearly always from seed, since the plant rarely produces plantlets. Thelocactus setispinus commonly known as Fish Hook Cactus, Hedgehog or Miniature Barrel Cactus is a globe-shaped to short cylindrical cactus about 8 to 12cm wide and up to 16cm tall. The 12 to 15 radial spines are needle-shaped, bright, brown or white and up to 4cm long. The 1 to 3 central spines are longer and stronger, straight and curved like a hook at the tip. The flowers are orange or dark yellow with a red center. This cactus blooms in summer. The red fruits are round or elliptical, a little scaly, about 8 to 10mm. 

Parodia is a genus of flowering plants in the cactus family Cactaceae. The genus is named after the Argentine botanist Lorenzo Raimundo Parodi who lived from 1895 to 1966. Flowers in all species arise from fuzzy buds, typically with bristles, at the apex. Flowers are cup-shaped and point straight up. They are easy to grow, have intriguing stems and spines and flower easily with brightly-coloured flowers. This fact in combination with their relatively small size, ensure that nearly all cactus growers will have some representative of this group. While advanced hobbyists may grow many of the various species and subspecies.           The genus has about 50 species, many of which have been transferred from Eriocactus, Notocactus and Wigginsia. They are native to the uplands of Argentina, Peru, Bolivia, Brazil, Colombia and Uruguay and range from small globose plants to 1 meter tall columnar cacti. All are deeply ribbed and spiny, with single flowers at or near the crown. Some species produce offsets at the base and most are free flowering, with stunning blooms throughout the year. These cacti are perfect for rockeries, where they will give your garden splashes of colour or as pot plants on a sunny windowsill. Either way you are assured of many years of joy. Parodia magnifica, formerly known as Notocactus magnificus and commonly known as Balloon Cactus originates from Rio Grande do Sul, Brazil. It is a cactus growing to 7–15 cm tall by 45 cm broad, with heavily ribbed, spherical to columnar, spiny and hairy stems, bearing pale yellow flowers in summer. The habitat where this plant comes from can become very cold during the winter nights. Often it will fall to just above freezing without harming the plants as it is also very dry. Therefore, if you live in a frost prone area, keep this plant dry during winter. It has gained the Royal Horticultural Society's Award of Garden Merit.

Parodia leninghausii is a species of South American cactus commonly found as a houseplant. Common names include Lemon Ball, Golden Ball and Yellow Tower cactus. Botanist Karl Moritz Schumann named it after Wilhelm Lenninghaus (1845-1918), a native of North Rhine-Westphalia who, in the 1880s, left his hometown of Ennepetal and emigrated to Porto Alegre, Brazil, where he became Guillermo Lenninghaus, and collected cacti for the German grower Haage. Parodia leninghausii is native to the Rio Grande do Sul province in the south of Brazil. In those regions, winter nights are cold, with a light freeze. These cacti survive in these conditions because they are quite dry at that time.
