This might be a silly question, but are you sure it is a real plant?
It looks vaguely like a mother-in-law's tongue (Sansevieria) with some sort of yellow sleeving to dress it up.
What happens in the pot - real soil and roots?
Are those leaves/stems completely round, or are they just tightly curved, sort of rolled-up?
What is that yellow top like - hard/soft??, powdery?, sticky?, can you peel it back?
Fred, do you recognize it?
There doesn't look like there is enough soil in the pot to support something like that.
Where did you get them?
Does it do any else? Has it flowered?
What length are the shoots?
Possible fungus ? (Clutching at straws here...)
Since the leaves are completely round, it is Sansevieria cylindrica, or it is purporting to be.
There is no natural explanation for the yellow tips. It is nothing to do with flowers or fruit; that happens nearer soil level (photo). Here's a nice series of photos showing the growth stages (though it happens to miss the flowers themselves) - http://forums.gardenweb.com/forums/load/sansevieria/msg1015282124832.html?11
And here's one of many sites advertising artificial Sansevieria
That site does't include photos, but many other 'artifical plant' sites, do, eg. Ikea
What you have is the yellow variant of what the vendor calls 'Sansevieria cylindrica spaghetti VELVET TOUCHZ® YELLOW'
That is a natural plant that has been artificially 'enhanced'. The same company also does them with other colour tips. The same sort of thing is done on many small cacti - where artificial flowers are pinned to the plants to make them more attractive/saleable.
