Salix eleagnos 'Angustifolia'
(synonym S. e. ‘Rosmarinifolia’)
eleagnos = like Russian Olive angustifolia = narrow leaf)
This choice shrub or small tree is known as Rosemary Willow as the small narrow leaves are reminiscent of the herb. It's a very attractive, compact large shrub that can grow to 15ft high by 15ft wide. The leaves are 3-6in long and 1/8-1/4in wide; gray at first, but later turn dark green above and dense white woolly hairs beneath. In spring there is a prolific burst of golden catkins on male plants and in fall the leaves turn a dazzling bright yellow. Ours are female plants, although some are yet to bloom. Hardy to USDA Zone 4.
USES: ornamental shrub in borders, by pools or ponds, even large rock gardens and containers.
NB: There is a willow called Salix rosmarinifolia from Eastern Europe that is very different from this willow. It's also very rare in North America, so if you see a plant labelled with the scientific name Salix rosmarinifolia, chances are it's mislabelled and it is really Salix eleagnos or, more likely, the narrow leaf form Salix eleagnos 'Angustifolia'!
Apparently in Finland S. rosmarinifolia is much hardier than what we know as the Rosemary Willow.
It may not be in the USA. If it is, I'd like to know where!
We are looking for a taxonomically verified plant of the species Salix eleagnos,
not the form offered here.
I would appreciate any leads to this
and will swap 10 cuttings of any plant in my list for
10 cuttings of this species--if it’s true to name!!!
Thanks very much!
This unique willow has a delightful feathery appearance and looks like a rosemary on steroids. Too bad it doesn’t have the same bouquet!

A great shrub for all seasons.

Female catkins that are just opening (L Denver Botanic Garden--early April) and those that have been fertilized and starting to show the fluffy hairs that help disperse the seed (R). Mid-May.

I have yet to see a male flower!
These female catkins are on one of my plants. Like many other Salix on my property it flowered freely in 2017 for the first time. I have no explanation unless it was the drought in 2016. Mid-May.
I spied this caterpillar while photographing the flowers at left. It wasn't eating my plant so I let it be. Early September.
The bushes to the right of this children's playhouse are old specimens of the Rosemary Willow on a tiny island. But not as old as the 300 year-old weeping willows behind them at left.
This scene is at Grand Pre in Nova Scotia in August 2016. A historical site well worth the visit.
It explains the horrors of the British and New Englanders who took the land off the Arcadiens.
Then in 1755 they split up families and shipped them to Haiti and Louisiana.
above and left: a shrub at the Chicago Botanic Garden with catkins opening in early April.
They coppice many of their willows regularly as you can see by the stubs left behind.
This keeps the bushes a more manageable size.
at left: One of several young specimens on our property. This one is wind blown in a late September storm. I loved watching the silvery underside of the leaves showing as I peared out of a bedroom window.
