I'm hoping to propagate Alder from hardwood cuttings. Do you know if
this is possible? Thanks in advance.

Just saying "Alder" leaves a lot of possibilities...

However the success rate for several of them looks pretty
good. For some into try looking he

"European and Red Alder" are listed. If you look through the
corresponding page they have this to say about European:

===
Vegetative Reproduction- European alder commonly sprouts
from the stump after cutting, and live branches can be
layered successfully. Root suckers are rare (60). In coastal
southern Sweden, alders live to maximum age of 100 years but
frequently produce basal sprouts and form multi-stemmed
stumps following death of the original stem (18).

Air-layering of alder shoots has been 89 to 100 percent
successful (84). The rooting ability of greenwood cuttings
of European alder seedlings less than 4 years old was found
to be generally high; over an 18- to 20-month period, 100 to
200 cuttings were successfully rooted from each ortet (25).

Alnus glutinosa can be readily propagated by in vitro tissue
culture. Plantlets of several clones were rooted within 3
weeks, subsequently transferred to soil mix, and maintained
in good physiological state for as long as 4 years (90).
