Yesterday I started this year’s first batch of seed. I’m usally sowing my cactus seeds at the beginning of March, but I’ve been otherwise occupied so I had to start a bit later than usual. 30 seeds each of the following species were sown:
- Lophophora williamsii (SB 418; Presidio County, Texas)
- Pelecyphora aselliformis (MMR 111.1; El Pedernal, San Luis Potosí, Mexico)

I’ve been looking for L. williamsii originating from the Trans-Pecos region of Texas for a while, so I was pretty exited to find the SB418 seeds from Presidio County, Texas. I’m looking forward to see how these plants develop (and also bought a batch of these seeds to start in my coldhouse).

Pelecyphora aselliformis is a first for me. I’ve always wanted to grow this distinctive species but for some reason never got around to it until now.
The seeds were started as described in the post on growing cactus from seeds and are bought from Jan Martin Jecminek.
Most of the seeds I’m growing this year have been selected for their (alleged;-) cold hardiness and will be sown later in my unheated greenhouse.
Update - April 12, 2008
Prompted by Patrick's comment I decided to include more detailed information on how the germination progresses. 5 days after sowing the seeds one Lophophora and 8 Pelecyphora seedlings had germinated (L=1/P=8). After 6 days the numbers were L=6/P=14, after 7 days L=13/P=17, and today (day 8) L=15/P=20. This means that after 8 days the germination rates for the Lophophora and Pelecyphora seeds are respectively 50% and 67%.
Update - April 25, 2008
April 19 the germination numbers were L=16/P=24, on April 22 the Lophophora germination count had risen to 19, and today April 25 the counts still are L=19/P=24. So after approximately 3 weeks the germination rates for the Lophophora and Pelecyphora seeds are respectively 63% and 80%. It should be mentioned that one of the Lophophora seedlings died off but is still included in the germination count (as it actually started growing but didn't make it from there).
