The cactus has been in the family for about 40 years. It flowered for the first time about three years ago. Last year it had 11 flowers, this year it had 59. I've never seen anything like it and would like to know what it is to learn more about it. Picture below.
Very nice! What evr you are doing you are doing it correctly. I do not know what it is, but if I had to guess it would be : some type of echinopsis.
G'day Cliff...it is hard to tell if those flowers are pink or white but it might be E. knippelianus or a hybrid thereof. You must be proud mate!! Ed
