My obsession with fasciation began with a monster-sized Rosario bulb from Buggy Crazy. As soon as it sprouted, right away I noticed that something was different, it wasn't a neat point of leaves as most sprouts are. As it got bigger and greened up, with so many leaves it look 'hairy'. There were 2 fasciated stems with a normal one on the right.
Here are some pics as Rosario progressed
I've had several more since then
What these all have in common is that they were healthy, mature bulbs and all had been planted or transplanted the year before. However, this year one clump in particular had every single stem fasciate ~ a clump that has been in place for several years and had previously given me the most beautiful, ribbon-worthy stems.
This calls into question another factor; a phytoplasma in the family that causes aster yellows, onion yellows and witch's broom. It is not clear if this is transmitted by sucking insects such as aphids, or if it is a transient in the soil. The clump shown here displayed several examples; flattened, twisted and split stems. We'll see next year how these lilies fair and may give us some indication as to the state of its condition.
Fasciation expresses itself in a variety of ways, such as ribbon, bifurcated (2-way split) and stellate (split into 3 or more stems), respectively.
