Sclerocactus from seed

January 09, 2005
Today I sowed my first Sclerocactus seed. I'd ordered some S. whipplei (SB472; Navajo Co, Az) and S. parviflorus (SB592; Torrey) seed without realizing they allegedly are very difficult to grow from seed.

I'm following Steven Brack's basic germination tips and his detailed instructions for Pediocactus, Sclerocactus and Toumeya. The seed are grown in a cold house and hopefully the freezing/thawing cycles in Denmark are sufficient for it to germinate.


  1. I sowed Sclerocactus uncinatus ssp. wrightii without any special treatment whatsoever. Seems to be a real slow grower, though.

  2. S. uncinatus is an easy grower. Those from the mountain regions of Utah and Colorado are the real stump.

  3. I have to admit that I haven't attempted to start any Sclerocactus from seed since I made this post. There seems to be general agreement, though, that S. uncinatus is a "goer" so I might try that next spring ;-)

    By the way, I didn't have any luck with the seeds I sowed back in '05.
