I thought many Parodia were lumped into Notocactus. No? I don't think Howard's plant is Notocactus roseoluteus. Its flowers are larger, with not so pointy petals & the pokeys stick straight out (rather than hug the plant). Blooms are lighter pink as well. Here's a photo of a friend's plant: Notocactus uebelmannianus blooms change color as they open. The blooms on Howard's plant are larger opened than mine ever were. But I believe that is what you have. I had 2 similar plants. The blooms never fully opened on the 1 seen below when I took pix. The other I missed seeing blooms altogether! :( I believe Parodia werneri is a synonym for Notocactus uebelmannianus, as is Parodia crassigibba.

Very nice! Always good to get great flowers from a tiny little seed.

Wow. Beautiful flowers. And looks like the one next to it is starting to flower too. Great job! Sadly though I know nothing about blooms and seeding 'cause none of my cacti have ever flowered, except the Mammillaria, but that doesn't count seeing as how I bought it in bloom.

sherrih: Remember that you must keep them moist, they don't have the succulence of adult plants. They might do better in a more humid environment (but various fungal disorders find this beneficial too). Would a 5oz drinking cup be big enough to start 25 seeds? Forgot that one ... Yes, I think so, for 25 seeds I use pots about 6-7 cm in diameter unless it is big seeds like Opuntia. It should have drainage holes, which is unusual in drinking cups (at least where I live). Do not forget to shade them if you put them in strong light (even behind a window), they are easily overheated. Perhaps I should stress that I have a slightly unorthodox approach to seed raising: I start them in a mix of cat litter (fired diatomaceous earth) and pumice. To decrease growth of harmful fungi and bacteria I first add water, heat the medium in a microwave oven and let it cool down. I fill the pots, and add some coarse sand, at least on the surface, if the pores between the particles are too wide. Then I sow the seeds, soak the growing medium with Chinosol solution and let the excess water drain away. The pots are put in translucent boxes with ventilation holes, and the boxes are placed in my propagator. The lights are on during day only. I keep them in this relatively humid environment until the seedlings are big enough for the next step (about 2-3 months old). This is a difficult period, I must watch them carefully for outbreaks of diseases, and I add more Chinosol now and then. Then I transfer them to tiny (2-4 cm) pots, 1-3 plants per pot, with a more normal cactus soil - this can be difficult to do without killing them. It is not the common way to do this, most growers sow in a more nutrient-rich medium and let them sit in the original pot as long as they can. My approach works better for me, I lose fewer seedlings due to root rot and mold now. There is also the Fleischer ("baggie") method, which gives very good results for many growers, but I have never tried it. When I first tried sowing cacti I lost about 95% of the seedlings. Now 95% of them survive, it is all about finding a method that suits you.
