Idk what constitutes many and non manly anymore. I guess growing plants and gardening type stuff is not "manly"? I have a lot of amaryllis flowers that bloom every year. I have 4 that I raised from seeds from my very first one. They bloomed a year ago. It takes 3 years of growth minimum before the bloom. They have some huge flowers. I have like 12 different ones now. 4 varieties. The first one is a pure red and I saved it. My mom got it as a gift for Xmas and after it bloomed she just threw the bulb out. I found it and repotted it. It bloomed on valentine's day. I call it my plant GF.
We also have moonflowers that grow all around our house. The local bees love them and I like going out in the evenings mid to late summer when they are all open cause they smell amazing.
I also like fermenting foods. Idk if that's considered not manly or anything but I like it and it's fun to me.
