Hello, My Oma has had these three plants for years. I also have part of the second one. It is more than 100 years old! I have no educated idea what these plants are, but my guess is the first one- grape ivy, second- maybe a hoya? and no idea on the cactus- not my thing. I have looked through the books I own as well as on the Internet without any luck. I just cannot figure them out! Also on the first plant how could I propagate it? It appears to have a woody stem so would I just root in water or soil? Or should I try air layering? (Which I have only read about.) Thank you much and I love the forum. P.S. From what I've seen from archive identifications, you guys are lightning fast. So I'll start the clock........now! LOL
