Geoblasta is a monotypic genus from South America, found in Brasil, Argentina and Uruguay. It has recently been discovered that flowers are pollinated via pseudo-copulation 1) by male Campsomeris bistrimacula wasps. Each plant bears one flower - a trait which seems to have a large correlation to this mechanism of pollination. The flowers shows close affinity with the genus Chloraea.

Geoblasta is quite an easy species in culture, requiring a compost with good drainage (sand) which is kept moist. The soil in their natural habitat contains a lot of rocks and grit. Plants prefer a sunny position, they don't respond well to a shady position or low temperatures.2). Use a soil with a lot of organic material, stones, charcoal, pine bark and sand.

The flowers open in the mid-morning and partially closed before sunset. The potted and unpollinated flowers remained open during 5 days, while those in the wild closed immediately after pollination. In the El Palmar site, the flowering of single plants and the one blooming episodes occurred between 11 and 20 October from 1999 to 2003. In Tandil site blooming occurred between 10 and 20 November in the years 1997 and 2004.
