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.|
|Here's another unusual growth on the same shrub.|
|Comparison to a normal apical stem tip.|
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.
