Description: Parodia gibbulosoidesSN|5810]]SN|5819]] Brandt (= Parodia gibbulosaSN|25271]]SN|5810]] Ritter ) is a low-growing cactus species forming cushions to 40 cm wide. It is similar to Parodia formosaSN|5810]]SN|25271]] but flowers are smaller and numerous 5 or more borne together. The stems are densely covered by short clusters of spines and the crown of the plant is completely shrouded in a thick short white wool.
Notes: Parodia gibbulosaSN|5819]]SN|5810]] was a provisional name used by Ritter in 1958, but even if the plants was widespread in cultivation it remained undescribed. Meanwhile Brandt validly published "P. gibbulosoides" in 1971. At last nine years later Ritter published the description of its “P. gibbulosa”, but it was already too late and this name is universally recognized as a synonym.
Stem: Spherical to shortly cylindrical 30 to 70 mm tall, 4-6 cm in diameter, pale to dark green, green.
Ribs: Completely divided into round, closely packaged tubercles only 4-7 mm wide which are arranged in 25 or more spiralling rows.
Areoles: 1.5-2 mm wide, with white wool in particularly young areoles.
Radial spines: 8-9(-11) straight, radiating, needle-like, 3-6 mm long, whitish at the tips often brownish or reddish, 1-3 upper ones darker and sometimes up to 10(-15) mm long, often longer than central spines and very like to them.
Central spines: One, erect, russet, 2-5 mm long.
Flowers: Small, 5 or more borne together, usually about 10-18 mm wide (sometime up to 30 mm), yellow; pericarpel 2 mm wide, greenish-yellow, receptacle about 10 mm long, 4 mm wide, light yellow, with yellowish scales and whitish wool. Bristles either completely absent or rare, very fine, 6 mm long, whitish or browish and only in the upper scales. Inner petals pale yellow, about 6 mm long. Filaments 2 mm wide. Style and stigma pale yellow.
Fruits: Only 2-3.5 mm wide, tan, with whitish wool.
Blooming season: Spring-Summer.
Seeds: 0.3 mm long, 0.2 mm wide, shiny, smooth with a very small strophiole.

Read More... Cultivation and Propagation: Parodia gibbulosoidesSN|5819]]SN|5819]] is an easy to grow tropical cactus, more cold tolerant than most and less fussy regarding soil conditions.
Growth rate: It is a relatively rapidly growing and easily flowering species that will make clumps given the best conditions.
Soils: It likes very porous standard cactus mix soil.
Repotting: Use pot with good drainage.
Watering: Water regularly in summer, but do not overwater (Rot prone), keep dry in winter.
Fertilization: Feed with a high potassium fertilizer in summer.
Hardiness: Reputedly sensitive to frost, but less so if kept on the dry side prior to, and during, cold weather (hardy to -5° C for short periods). However warmth throughout the year will increase the grower's success (8-12°C during rest season).
Exposition: Outside bright but partially filtered sunlight or afternoon shade, inside it needs bright light, and some direct sun. Subject to sunburn if exposed to direct sun for too long. Tends to bronze in strong light, which encourages flowering and heavy wool and spine production.
Uses: It is an excellent plant for container growing. It always looks good and stays small. It look fine in a cold greenhouse and frame or outdoor in a rockery.
Pests & diseases: It may be attractive to a variety of insects, but plants in good condition should be nearly pest-free, particularly if they are grown in a mineral potting-mix, with good exposure and ventilation. Nonetheless, there are several pests to watch for:
- Red spiders: Red spiders may be effectively rubbed up by watering the plants from above.
- Mealy bugs: Mealy bugs occasionally develop aerial into the new growth among the wool with disfiguring results, but the worst types develop underground on the roots and are invisible except by their effects.
- Scales: Scales are rarely a problem.
- Rot: Rot is only a minor problem with cacti if the plants are watered and “aired” correctly. If they are not, fungicides won't help all that much.
Propagation: Direct sow after last frost. Seeds germinate in 7-14 days at 21-27° C in spring, remove the glass cover gradually as the plants develops and keep ventilated, no full sun for young plants!
