How do you propogate calla lily seed?
First, just keep an eye on the flowers. If your calla is happy, then in my experience about half the flowers will self-pollinate and begin to develop. Cross pollination is I’m sure possible, but I don’t know the natural vector for that. Look down into the flower, and you’ll see little kernels forming along the stamen. Wait a couple weeks, and if the flower seems to be fading, and these little kernels have failed to further develop, go ahead and cut off the flower.If they are developing, and you’ll be able to tell, as they grow larger and plumper, and the whole stamen will begin to resemble a small cone, or pineapple shape. Just be patient, it can take up to several months for the cone to mature. Eventually, the cone can get as long two to five inches, and as thick around as an ear of corn. You’ll notice as the cone matures, it’s increasing weight will naturally bend the stem until the cone is resting on the ground. Keep an eye on it, and you’ll see the kernels begin to turn yellow and
