Hi Ken and List, Yes, I to have observed that yellow Veltaheimia bracteata are very reluctant to set seed, unless they have been hand pollinated. The easiest way is to do this is to use a small paintbrush, insert it into each flower and give it a little twirl, so that it can collect and deposit some pollen. Be sure to use a different brush for your pink Veltheimias! <G> It is a strange thing how plants can coordinate their flowering, take Neomarica caerulea for example, with few exceptions every single flower on all my plants open on exactly the same day! And to a lesser extent, the flowering of Ken's Yellow Veltheimia last month, mine plants, on the other side of the world, are just about to start flowering in a few weeks time! Kind regards, Pieter
