Posts Tagged ‘Fronds’

We all know ferns and we all know bracken. But how can we tell the difference between the two? Easy, says Dave our woodland tree and plant specialist.  Just compare the pinnate.

The pinnate is the feather-like leafy bit that comes out of the stem. Ferns are bi-pinnate, which means that the leaflets divide twice to produce the easily recognised fronds. Bracken, on the other hand, is tri-pinnate. This means that the leaflets divide three times, giving each frond its own tiny frondlets – like a little green comb.

See if you can tell which is which in the photograph below. The answer’s at the bottom.
