Stelis glomerosa 'Lucille'

Stelis glomerosa (the name "glomerosa" refers to the ball-shaped flowers), is from Ecuador and belongs to a huge genus of plants whose flowers are often very similar and very small and undistinguished.  This species is different in having larger flowers with a very distinctive shape.  My plant is 5 cm tall, but seems to be getting larger.  It tends to ramble and produce new growths that come from the top of the previous growths, making it impossible to contain in a pot.  The flower spikes reach 10-15 cm and the flowers are slighting more than .5 cm in size.
