A single head reaches up to \u003cstrong\u003e15 cm\u003c\/strong\u003e in height and \u003cstrong\u003e5–7.5 cm\u003c\/strong\u003e in diameter. It is distinguished by a rare ability among cacti to divide its apex into two: a single sphere develops into a pair of twin heads resembling an owl's gaze. Hence the trade name “Owl’s Eyes”.\u003c\/p\u003e\u003ch3 style=\"font-size:14pt;\"\u003e\u003cstrong\u003eGrowth and development characteristics\u003c\/strong\u003e\u003c\/h3\u003e\u003cp style=\"font-size:12pt;\"\u003eThe stems are spherical to shortly cylindrical, bluish or dark green, and slightly broader at the top. The tubercles are pyramid-shaped and arranged spirally in \u003cstrong\u003e13–21\u003c\/strong\u003e rows. Each areole produces \u003cstrong\u003e3–5\u003c\/strong\u003e radial spines and no central spines; the lower ones may reach \u003cstrong\u003e25 mm\u003c\/strong\u003e, and in some specimens even \u003cstrong\u003emore than 5 cm\u003c\/strong\u003e. Young spines are cream-coloured with brownish tips, becoming chalk white with age. White, woolly tomentum forms between the tubercles, while damaged tissue exudes milky sap. Further divisions of the apex lead to the formation of clumps that may reach \u003cstrong\u003e50 cm\u003c\/strong\u003e or more in width after \u003cstrong\u003e12–15 years\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3 style=\"font-size:14pt;\"\u003e\u003cstrong\u003eFlowering and fruiting\u003c\/strong\u003e\u003c\/h3\u003e\u003cp style=\"font-size:12pt;\"\u003eFlowers appear in spring and summer, forming a ring just below the top of the head on growth from the previous season. They are funnel-shaped, approximately \u003cstrong\u003e18–25 mm\u003c\/strong\u003e long, creamy white with a reddish-brown central stripe on the petals. After flowering, elongated, club-shaped fruits develop in an intense red colour, containing small brown seeds. The red fruits among the white spines provide additional ornamental value.\u003c\/p\u003e\u003ch3 style=\"font-size:14pt;\"\u003e\u003cstrong\u003eOrigin and natural habitat\u003c\/strong\u003e\u003c\/h3\u003e\u003cp style=\"font-size:12pt;\"\u003eThe subspecies occurs in Oaxaca, around Nejapa and the Totolapan River valley, at an altitude of \u003cstrong\u003e850–1650 m above sea level\u003c\/strong\u003e. It grows in dry tropical deciduous forests and xerophilous scrublands, where the rainy season alternates with a long dry season. According to Plants of the World Online (Kew), the taxon is treated as a synonym of the broadly circumscribed species \u003cstrong style=\"color:#656B39;\"\u003eMammillaria karwinskiana\u003c\/strong\u003e, which has Least Concern (LC) status on the IUCN Red List.\u003c\/p\u003e\u003ch3 style=\"font-size:14pt;\"\u003e\u003cstrong\u003eGrowing requirements\u003c\/strong\u003e\u003c\/h3\u003e\u003cp style=\"font-size:12pt;\"\u003eThe plant needs as much light as possible - ideally \u003cstrong\u003eat least 4 hours\u003c\/strong\u003e of direct sunlight per day - to maintain its compact habit and white spination. The substrate should be very well drained and mineral-based: ready-made cactus soil with the addition of perlite, pumice or grit. The cactus is not frost-hardy; with completely dry soil, it can briefly tolerate approximately \u003cstrong\u003e-4°C\u003c\/strong\u003e, corresponding to \u003cstrong\u003eUSDA zone 9b\u003c\/strong\u003e. In Poland and central Europe, it is grown in a pot and can be placed on a sunny balcony in summer.\u003c\/p\u003e\u003cp style=\"font-size:12pt;\"\u003eDuring the growing season, water thoroughly, but only after the substrate has dried out completely; excess moisture can cause root rot. In winter, it requires a cool (approximately \u003cstrong\u003e7–12°C\u003c\/strong\u003e), bright and dry rest period, which encourages subsequent flowering. From spring until the end of summer, cactus and succulent fertiliser may be applied; fertilisation should be stopped in winter. Fast-growing clumps should be repotted every \u003cstrong\u003e2–3 years\u003c\/strong\u003e into a slightly larger pot.\u003c\/p\u003e\u003ch3 style=\"font-size:14pt;\"\u003e\u003cstrong\u003eOrnamental uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp style=\"font-size:12pt;\"\u003e\u003cstrong style=\"color:#656B39;\"\u003eMammillaria karwinskiana subsp. nejapensis\u003c\/strong\u003e is an attractive plant for windowsills, greenhouses and cactus collections. Its branching heads, white tomentum and long spines look striking in shallow bowls and arrangements with other succulents. Its ease of cultivation makes it well suited to beginners, and over time it forms an impressive multi-headed clump.\u003c\/p\u003e","brand":"mr.seed","offers":[{"title":"10","offer_id":54314062119240,"sku":"2943","price":6.9,"currency_code":"PLN","in_stock":true},{"title":"50","offer_id":54314062152008,"sku":"2944","price":33.0,"currency_code":"PLN","in_stock":true},{"title":"100","offer_id":54314062184776,"sku":"2945","price":59.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0939\/2649\/0440\/files\/Nasiona-Kaktusa-Mammillaria-karwinskiana-subsp.-nejapensis-1.webp?v=1792059879","url":"https:\/\/www.mrseed.eu\/en\/products\/nasiona-kaktusa-mammillaria-karwinskiana-subsp-nejapensis","provider":"mr.seed","version":"1.0","type":"link"}
