The Euphorbia obesa FamilyAnother entry category we have in our C&S Society's Annual Plant Show is "Parent/Offspring". In this category you enter seedlings, rooted cuttings, or rooted offsets, and the plant(s) from which they came. My entry this year was a pot of Euphorbia obesa seedlings, and the parent male and female plants that were used to produce the seed. Euphorbia obesa is a dioecious species, which means there are male and females flowers, and they are produced on separate plants. To produce fruit and seed you need both a male and female plant in flower at the same time. Shown below is the female plant on the left (unfortunately not in flower), the male plant on the right (the tall guy), and the seedlings (the kids) in front.
The "other" problem (in addition to having a flowering male and female plant) to producing Euphorbia obesa seed is that the fruit is a regma, a capsule that when ripe explodes and shoots the seeds far and wide. Thus, there has to be some procedure set up that can capture the seed when it is expelled. There are three seeds per each fruit and they are relatively large. The seed germinates easily and this is the only way to produce more plants, since E. obesa rarely, if ever, produces offsets.
