Greetings from Mike44 in Berkshire UK.

I am new to Cactus cultivation and became interested after purchasing some seeds for the Grandchildren.
Not yet knowing which are easy for beginners I started with some mixed seed collections am now faced with the
task of identifying them but waiting for them to become larger before attempting that exercise. I have a small number
of mature specimens, mostly mammillaria from local garden centre and a few others from commercial sellers.

Once the cactus bug bites its very difficult to stop adding just one more plant!
Welcome and enjoy.
