Dirr describes Broadmoor thus:
"A dwarf, low-spreading, staminate form which looks like a neat form of var.
TAMARISCIFOLIA when young, but the plant tends to build up at the center
with age, the main branches are strong and horizontally spreading; the
branchlets short and reaching upwards; the sprays very short, occurring
mainly on the upper side of the branches; the foliage is a soft grayish
green and is resistant to juniper blight; this clone as well as 'Arcadia'
and 'Skandia' were selected from many thousands of seedlings raised by D.
Hill Nursery Co., Dundee, IL from seed imported from near Saint Petersburg,
Russia in 1933; all have proved resistant to juniper blight; Zone 4; will
grow 2 to 3' high and 10' wide or more..." Staminate describes an imperfect
flower with only functional stamens, male.

That is a very good description of the ones we have, except for the berries.

I found out it's even difficult to ID an Iris Cohen. There are three "clones"
by that name on AOL, and two of them are social workers. ;-)
