During the summer (which was rather succesful for me, houseplant-wise) I grew my Euphorbia plants outside. One, which is tall and has leaves coming out of its stems, flowered and two of the several flowers became fertilized. Now, they're maturing in my sunroom. What do I do now? Is it possible to sow the seeds when they become ready? Do Euphorbia have high mortality rates with seeds? I'll try to post some pics in a couple weeks.
