Hi everyone! Though I've looked after most of these cacti for a number of years, it has only just dawned on me that I have no idea what type of cacti I have. The websites I've looked at have left me a bit confused, so your help in identifying them would be very much appreciated. The images are ordered by age, youngest to oldest from left to right. The parent cactus of the youngest ones (first image) was tiny when I got it and was out of soil and not watered for a number of years. When it was eventually planted it grew very quickly and spawned all of the other babies you can see in the same pot within a few months. Cheers! Simon
