I prefer ones which release their fragrance into the air rather than needing to be bruised first, so my favourite is probably night stock, Brompton stock, hyacinth, strongly scented roses and Jasmine, which can't be beaten on a warm June evening. Wisteria, though (we have a large one here, beneath my balcony) produces quite a strong fragrance when its all in flower.

Viburmum 'Dawn' and Mahonia xmedia 'Charity' both have alovely sweet perfume early in the year are two of my favorites

Nice question! I would love to know more fragrant plants, but meanwhile I love Philadelphus, Stock, Prosthantera (mint), hyacinth and Daphne bholua. Oh, and Sarcococca in small doses, and Jasmine and Honeysuckle.

Any of the Daphnes, crocus, lilies, irises... loads in fact

Night scented stock, night scented phlox, Brugmansia and honeysuckle on a warm evening. Also love deep blue petunias for their heavy scent.

One to try if you can get it is night flowering jasmine or Cestrum nocturnum. Needs protection but if you have a conservatory, they are just awesome.

Pansies, wallflowers and polyanthus take a lot of beating on a warm spring sunny day and i just love the peppery smell of cyclamen.

Loads of scents to treasure here, many thanks.

I had forgotten honeysuckle and wisteria for some strange reason - both of these grow on either side of our kitchen door!

I particularly like the scents on the air on a warm summer's evening.

Pansies have a fragrance too - when I used to buy several trays of them in autumn for bedding, the scent in the car on the way home would be overpowering. Not noticeable outside too much though.

Yes Bamboo, I have noticed their lovely fragrance too, also at the garden centre itself when I walked past rows of trays of them!
I actually have great difficulty in waliking past rather than stopping to buy some!!

I like honeysuckle best of all, on a summer evening. Lily of the Valley and my old-fashioned soft Jacobite rose and Viburnum bodnantense are others I really like. Oh and Philadelphus.
Scent is such a personal preference, but the thing I find interesting is the fact that a particular plant scent can immediately and powerfully trigger a memory.

My all-time favourite is not a strong one, but skimmia flowers have the most delicious, old-fashioned fragrance. Paperwhite narcissi smell so clean and fresh, honeysuckle is very heady, hyacinths are wonderful, wisteria is heaven in a breath. Chrysanthemums are the very essence of autumn, but the smell of tomato plants in a greenhouse when you have been nipping out the side shoots is my childhood encapsulated.

I,d forgotton Philadelphus Ojibway.......the one that smells like bubblegum, single white flower with darker centre, maybe Belle etoile?

That's the one, Pamg! Like Gattina, that scent plunges me straight back to being a child.

The exquisite scent of Sweet Peas or Viburnum 'Mohawk' is superb but the best scent of all is the smell given off by the soil as it warms up on a sunny day in spring giving the promise and expectation of what is to come.

I like the yellow primroses - the only colour of the cultivated ones that seem to be scented. They smell like the wild ones but perhaps a little stronger.
Wild bluebells, honeysuckle, narcissi and yes skimmia too, which I noticed today as I came down the path. Too many to list really. Freshly cut grass is good too. And the mushroomy smell of woods in autumn, and the smell of warm moorland....

Marks and Spencer used to do a room spray called "Cut Grass", which was really very close to the real thing - I loved it, but, sadly, as always when I find something I like, they discontinued it! Yes, Steragram, may I copy you and add cut grass to my list, too?

Sweet rocket and the tall white nicotiana sylvestris and the rose 'Compassion'. Oh, and lilac!

Hello all. Long time since I added a comment but couldn't resist adding freesia, choisya and nemesia to the list.

Scents from childhood for me - Cosmos, a very particular smell rather than scent, and the smell of a blackcurrant bush as you pinched the blackcurrants when no one was looking!

I'd forgotten sweet rocket . . . and none of us thought of Sweet Peas!!

Lemsly Aser is another great scent that fills the room.

Reading down this list again, just realised I have a huge smile on my face. Thank you for so much pleasure everyone!

It's a good one, isn't it Stera . . . loads of ideas for us all. I've never known a question go on for so long!

Btw, what is Lemsly Aser, Myron??

I am so glad that I happened to ask you all about scented plants as your answers have been wonderful to read.

I too love sweet peas - how could I have forgotten those in my own list?

We have just bought a skimmia because bees are supposed to like its scent too!

Yes, Myron, what is Lemsly Aser? We are all waiting to hear!

I just re-read your original question, Wildrose, and it has prompted me to add another two scents - wild acacia flowers and broom. In about a month or two, all the way down the back road to the nearest town, the mountainside is lined with big, white-blossomed acacias and broom bushes - scents of the Mediterranean. Not particularly sweet, but very atmospheric and heady.
