Can you suggest some very fragrant lilacs, and a source, for my garden?
Well, common Lilac (Syringa vulgaris) and its varieties/cultivars win for best scent, as they are extremely fragrant. There are many cultivars--2,000 at the Arnold Arboretum. Here is the arboretum's list of lilacs with the highest degree of fragrance:
Syringa ‘Laurentian’ (blue)
S. ‘President Lincoln’ (blue)
S. ‘Adelaide Dunbar’ (purple)
S. ‘President Roosevelt’ (purple)
S. ‘Charles Joly’ (magenta)
S. ‘Ruhm Von Horstenstein’ (magenta)
S. ‘Catinat’ (pink)
S. ‘General Sherman’ (pink)
S. ‘Katherine Havemeyer’ (pink)
S. ‘Vauban’ (pink)
S. ‘Asessippi’ (lilac)
S. ‘Excel’ (lilac)
(Google for images of the above lilacs)
Culture: Best soil is one close to neutral and supplemented with added leaf mold; faded or old flowers should be cut off as soon as flowers fade; lilacs are very resilient plants.
Planting: Best done in early spring or fall.
