The remarkable polycephalic habit of Ferocactus robustusSN|21488]]SN|21488]] is quite unlike that of any other species in the genus. ![]() Fruit must be significantly overripe before harvesting seed clean and dry seeds.Description: Clumping small barrel cactus, that forms powerful colonies of hundreds of branches, reaching over 90-100 cm high and 3(-5) m wide. Propagation: Seeds are the only way of reproducing. Plant in good conditions will start to bloom when reach the diameter of only 12-14 cm. This plants need a period of cool rest in winter to produce flowers abundantly.ĭiseases and pests: Watch for infestations of mealybug, scale insects and spider mite. ![]() It can tolerate moderate shade, and a plant that has been growing in shade should be slowly hardened off before placing it in full sun as the plant will be severely scorched if moved too suddenly from shade into sun.įrost Tolerance: Light frost protection required for safe cultivation, but can tolerate sporadic light frost. Feed with a high potassium fertilizer in summer.Įxposure: Outside they need a bright exposure, full sun or half shade in summer if the location is exceedingly hot or bright, inside needs bright light, and some direct sun. No water should ever be allowed to stand around the roots. A wet cactus in the sun light can cause sun burning which can lead to scars or even fungal infections and death, keep rather dry in winter. Water regularly during the aestival growth cycle (this plant need plenty of water, but do not overwater and let their soil dry out between waterings), and also needs to be avoided wetting the body of this plant while it is in sunlight. After repotting, do not water for a week or more. Fill about a quarter of the pot with broken crocks, gravel, etc. ![]() However, this doesn't necessarily mean they'll need larger containers. Generally, they should be repotted every other year in order to provide fresh soil. If potted, repot them preferably in the spring, if their roots become cramped. They are suited for any rich, well drained soil such us clay, pumice, lava grit, and only a little peat or leaf-mould. Seeds: Conspicuously bur minutely reticulate, elongate-obovoid 1,6-1,8 mm long, hylum basal but oblique.Ĭultivation and Propagation: Ferocactus viridescensSN|13617]]SN|13617]] are winter-growing plant, but adapts well in cultivation to a cool winter resting regime, and quite easy plants thought slow to start. Stigma lobes yellow.įruits: Barrel-like, bright yellow (very rarely reddish) with a pleasant acid taste, 20-35 long and 15-25 mm across, fleshy, skin leathery with about 30 fimbriate-denticulate scales. Perianth-segments oblong, obtuse, sometimes apiculate, more or less serrulate on the margins, greenish yellow or greenish with some pink, sometimes with reddish brown midstripes flower-tube bearing stamens almost to the top of the ovary scales on the ovary orbicular, imbricate. Radial spines: 10-20 per areole, similar to the centrals but smaller 1-2 cm long, spreading irregularly, stiff and straight.įlowers: Infundibuliform 2,5-5 long 3-6 cm on diameter, colour similar inside and out. As younger plant does have colourful spines. ![]() (rarely absent).Ĭentral spines: 4 per areole forming a cross, spreading at about 45° angles, the lower one stronger and more flattened, narrowly elliptic in cross section, straight or slightly curved, conspicuously annulate, principal central spine 30-50 cm long and 2-3(-5) mm broad. Spines: 10-19 per areole, central spines and larger radial spines pink or yellowish, becoming duller by age or turning yellow or horn-coloured, smallest spines per areole slender, sometimes bristle-like, less than 1 mm diam. Ribs:: 13-21, 1-2 cm tall somewhat rounded, obtuse, undulate shallowly notched immediately above each areole.Īreoles: Narrow elliptic to oval 10-20 mm long with brownish tomentum, spine-bearing in the lower part, felted in upper part, flower-bearing and also with several reddish glands, these becoming elongated and spinescent in age. Stems: Pale to deep green, somewhat glossy, erect, mostly depressed-globose or globose (to short cylindric), with little apical pubescence, usually 10-30(-45)cm tall and 10-20(-35) cm in diameter. Description: Ferocactus viridescensSN|13617]]SN|13617]] is a solitary barrel cactus, sometimes wider than tall. ![]()
