These adorable astrophytum seedlings are now 3 months old. Not all of them grow at the same pace. This one seedling is miles ahead of its brothers and sisters.
These seed grown 3,5 years old Mammillaria plumosa are now bigger than my hand. They’re currently staying in a 15 cm pot, but it won’t be long before they need an even bigger pot. This is the fastest growing cactus I have ever grown from seeds. There are actually two plants in there. The big bulb on the second picture (top right near the white string hanging from the wall) is the brother of the big mass that turned out to be the faster growing seedling.
I wonder how big this plant is going to get.
I found these seed packets with Stapelia gigantea and Selenicereus grandiflorus a month ago and decided to give it a try. I don’t think the Stapelia seeds will germinate, because I couldn’t keep the seeds from being overtaken by black mold, even after a good hydrogen peroxide soak. The Selenicereus grandiflorus are doing okay right now. A month after germination, a couple of them have grown these little spikes and they’re adorable!
Selenicereus grandiflorus are known for their huge, beautiful flowers, but the plants themselves can be kind of bland. This is why I love cacti, though. They can blend in with the background, sometimes even be downright ugly for years, but when they finally decide to bloom, they’re magnificent. Even if the flower only lasts for one day.
Look how adorable my little CO x OR hybrids are today! They’re like little fluffy stars.
I recently took them out of the little greenhouse, I kept them in. Some of the old seed shells started to grow some sort of white fungus, which would have killed the nearby seedlings very quickly if I hadn’t removed the top of the greenhouse. Astrophytum seedlings are notorious for dying from damping off, so maybe it was about time I introduced them to lower humidity.
Right now I keep the soil from drying out by watering a couple of times a week. They’re still under grow lights and probably will be until next spring. They’re still way too small to experience the late summer sun.
I’ve been waiting for my Hildewintera colademononis to bloom since 2017 when I bought them as small unrooted cuttings. When I bought them, each of the cuttings were no larger than a pinky.
I really like this cactus, probably even more than most of my other cacti. I’m just a really big fan of hanging plants, especially when they don’t have to be grown indoors to thrive.
This Hildewintera loves whatever you throw at it. It loves a good amount of water in summer and also to be kept completely dry in winter. It does stretch if it’s placed in less than ideal lighting and it can burn if given too much direct sun. The placement I chose for it on my balcony seems to be perfect, with direct afternoon sun and indirect light the rest of the day in summer. In winter, when the sun hangs lower in the sky, it gets (weak) direct light all day.
Little fuzzy ribs are starting to form and the spines already went from white and transparent to dark brown. I remember my Astrophytum myriostigma seedlings being less hairy than these CO x OR seedlings are right now. I think this means that the coahuilense genes are present and the cross pollination was a success!
Look how massive my seed grown Astrophytum myriostigma is now! I’m such a proud plant mom. This is the biggest of the three plants and it seems to grow at a much faster pace than its siblings.
I don’t have too much to say about this one. It’s just perfect in every way!
My Astrophytum CO x OR seedlings are very much still alive. Most of the seedlings have now developed little fluffy haircuts and short, white spines. The grow lights are doing their job keeping the seedlings from etiolating. I may have placed them a little bit too close to the lights because some of them are a tiny bit too red or brown. I’ve lost exactly 0 seedlings so far, so I think the lighting situation is going to be okay.
Maybe it was the new pot or maybe it happened because I started to fertilize. But the Sulcorebutia rauschii exploded with growth in spring and especially here in summer.
I love this one because of its color and because they grow in big clusters, filling out the entire pot in no time. A couple of years ago I saw one in a garden center labeled as “rare cactus”. The cluster was just about the size of mine and it cost DKK 300 ($40). I bought mine as a mini-plant with only one head for DKK 25 ($3) in 2017. I’m glad I didn’t buy it back when I first saw it.
There’s fluff on the CO x OR seedlings already after 2 weeks, and also tiny transparent spines. It’s nice to see them grow this fast without any casualties. They probably inherited the hardiness of the Astrophytum ornatum.
