Couldn't help the corny post title.
Plants never cease to amaze me, they create such interest and wonder.

| Here, fasciated growth has formed on a tip of this Lilac (Syringa vulgaris) stem. You can see lateral buds trying to form, but are squeezed and hardened. |
To define: Fasciation is an abnormal condition of plant tissue growth that happens on the apical meristem (tip growth) of the plant. It generally creates a flattened portion of tissue, looking like concentrated stems all fused together in a clump. I've seen it happen with flowers, fruit and sometimes the root.

Interestingly enough, some offshoots of this sort of growth have created new cultivars - like Fasciated Willow, used widely in the floral industry.
I've seen fasciation on very few deciduous shrubs - mainly willows. Never yet seen on lilac as this one.
Cause: genetic, bacterial, viral, fungal, hormonal and of course, environmental. That's my guess in this situation. This lilac is flanked by a salted walkway and roadway in the winter. Quite exposed to prevailing winds. However, I may be wrong.
Quite fascinating.
