Giant or Gigantic?

One of the hogweeds at the far end of the garden is huge, much taller then our usual plants and way above my head, but I'm almost certain that it's just a gigantic normal one,  encouraged by the abundant water it's had. I wanted to get it backlit by the late afternoon sun but it was difficult to frame it without pointing the lens directly at the sun. This is the slightly later, but preferable, attempt - even later would have been better still, but a pesky cloud cut off my light source.
