Oxalis pocockiae bulbils

Hi Nhu

These bulbils will grow and eventially brown and become dislodged from the 
mother plants, usually when the leaves die down.

The are very light, and can be blown by the wind, or carried away by water.

If kept cool or in shade for the summer, most will grow next year. Some 
might even flower the first year, but most will flower only the second.

Other species that do this often is O. inaequalis (will post a pic to the 
wiki later, with up to 400 bulbils per plant), and I've seen it on some 
clones of O obtusa (rarely).

Unfortunately this is a characteristic that should carry a warning when 
these plants are distributed - these bulbils can escape, and greatly 
increases the weed potential of the particular species or form.
