A petite cactus with a pure, elegant air: its white, wax-coated body is topped with fluffy, cottony tufts, and it blooms with delicate white flowers. Although its slender spines are mostly white, their tips are black, creating a striking accent—which seems to be the origin of the name 'Kokusoumaru'. Overall, it gives off the vibe of a 'white holy knight wielding a spear black only at the tip.'
Growth is slow, and even when fully mature, it only reaches about 7 cm; it rarely forms clusters, so you can expect it to keep its charming appearance for a long time (even though it stays small, that's the finished plant—so please understand the somewhat higher price).
Scientifically, it's classified under the genus Turbinicarpus, but it is still often called by its old genus name, Gymnocactus. It resembles other former Gymnocactus species like G. beguinii , G. knuthianus , and G. saueri , but with its white skin and fluffy fuzz, it also shares a horticultural kinship with Lophophora. The reading 'kokusoumaru' is the most common way to pronounce its name.

@TokyoAA831 このサボテン『ギムノカクタス 黒槍丸』の名前で入手したんですが、黒槍丸の花って基本は白花みたいなんですよね。個体差なのか、突然変異のレアものなのか、ラベル違いなのか。
@shiTOpa222 黒槍丸は刺が長いものばかりと思っていましたが、画像検索したら短いのもあるみたいですね。この時期でも開花は凄いです。昔ビーレッキー持ってましたがこれもよく咲きました。ギムノカクタスは多花性のが多いですね。
@meloformous いえいえ、忘れたら何度でも質問してください! 1,2枚目はエキノカクタスの太平丸と翠平丸、 3枚目はコピのschulziana、 4枚目はギムノカクタスの黒槍丸っす! みんな鮮やかでみずみずしい刺出してて良き〜
