Back about 1970 in Great Falls, MT, I brought home a discarded lilac twig, and shoved it into the ground. It got no extra watering or special care, but still grew into a nice bush that bloomed every year. The bush is still there!

Lilacs are a common hedge here in Montana. In fac I plan to put in a hedge of lilac -- probably just use sticks from the existing bush.

It was fun to experiment making it to bloom in fall for the second time in a year (the first time is always in spring) with bone meal and proper pruning.

I live in zone 6 here in Ontario and it is very interesting to see my one year old seedling stay evergreen through cold winter here!! Wow, that is hardy!

Here in El Paso, the lilac does rather poorly unless grown in moist soil. It does very well at higher elevation in the nearby New Mexico pine forests. I have tried various types of lilacs here and they will dry up and die completely quite rapidly if they aren't watered constantly. They also fail to thrive in the way one would expect a lilac to perform. I have a lilac at death's door in my backyard that we brought down from Wyoming, where the weather isn't too dissimilar part of the year to the weather here, i.e. hot and dry, but it has simply clung to life for many years and this year, with only 3" of rain through September, it looks like it is finally going to cash in. Perhaps lilacs would do better down by the river, but not in areas once covered desert, which includes most of this... read more

There is a lilac tree growing in my back yard that has been there since my father was a child. It was about 15 feet tall until we trimmed it back. A nasty ice storm had messed it up back in December 2008 and it needed a good trim to grow back into a nice shape. It flowers every spring with white flowers. I like it very much as purple lilacs are far more common than white.

I planted some new pink lilacs nearby but they were chewed down by rabbits. I decided to place a cage around them this year and I have been rewarded with about 2 feet of growth.

I have more of a question than a comment, though like most others commenting on this flower I love and miss it after growing up in CT with lilacs blooming all around the yard to now living in Florida and occasionally seeing lilac if I make it to Ct early enough in the spring. My friend brought me a couple of lilac bushes back from NC where a man was selling them and stated they came from TN, I have yet to plant them (having received them 2 days ago) I am almost afraid but so much want them growing in my yard here in Florida. Any comment about it being possible? If so any suggestions on best place to plant them, perhaps under the shade of palm trees so the wicked summer sun wont burn them??? Thanks for any info.

Yes, my lilac suffers from powdery mildew after it has flowered. I haven't attempted any remedy, figuring the old gal hasn't changed her habits much despite it. Almost completely bare by November, and planted in front of an evergreen laurel hedge, it is a favorite hangout of the wintering backyard birds.


On Jun 4, 2008, Malus2006 from Coon Rapids, MN (Zone 4a) wrote:

They have very nice fragrance - they tend to be more often planted in the North part of the Eastern United States - from personal observation - there are a somewhat invisible line somewhere from southern Missouri through Kentucky and then curves north to southern Pennsylvanica where lilacs are more common north of that line while Crape Myrtle are more common south of that line. Out west, it becomes more fuzzy - mainly confined to the Northern Rockies Mountains with islands further down then a narrow belt in Oregon and Washington State.

The main negative factor is that they are very vulnerable to powdery mildrew - a white fuzz often develops on their leaves by mid summer and it is lethal to some young suckerlings that grows beneath the mature plants but not for those who gro... read more

we bought two of these 3 years ago in the fall. the first year, only one bush put two clusters of blooms, the next year, i transplanted them, and none bloomed, i was really bumbed:( but this spring, they are puting out many new clusters of flowers, and on one, 1 foot by 1 foot bush, i counted over 30 clusters of flowers! I cant wait to see what it looks like in full bloom!

While many seem to enjoy this scent. Many of us are very allergic to lilacs. They not do not smell good to us but can cause lots of problems. I just want to suggest planting a crepe myrtle instead of a lilac. They are much prettier, bloom all summer, 9 months in my area. They come in many colors including all the purples. Since they don't smell they won't potentially make you and others sick.


On May 23, 2007, Opoetree from Oak View, CA wrote:

We have had about a dozen lilacs growning around our property for the past twenty years. This past spring they bloomed exceptionally well and the scent was heavenly. I was able to pick large bouquets and combine the lilacs with bunches of yellow roses...quite a showy combination! I always think of Louis May Alcott's UNDER THE LILACS story when I see lilacs. Such a totally attractive plant...visually and sensually.

I got a few shovels of purple lilac root starts 2 years ago from our neighbor's overgrown Lilac. Now we have a dozen Lilac bushes growing in clumps along our fence line. I'd like to add yellow, red, blue, pink, white & the traditional lilac to the property. How could one have too many lilac shrubs? They are a no maintenance plant except you may find it beneficial to dig up new root starts every other year or so to stop the plant from spreading too much.

One of my most fond memories as a child was the
oh-so-sweet smell of Lilac coming from the neighbor's
home next door.

Though I was later transplanted from New York to
New Mexico, around the map and finally landing in
Oklahoma, I knew I would have a Lilac of my own one day.

Cutting to the chase, you have to water your Lilac or
it won't make it. Silly me, I plunked a Lilac out in the
middle of the side yard and waited. And waited. But
at the time I didn't realize how important it was to water
in and keep your young plants watered. All throughout
the year, not just the 'growing' season, as all year is a
growing season for some things.

This year, my Lilac looks better than ever.... read more

I was told that lilacs probably wouldn't do well in KY but my 2 year old bush (started from a sprout brought down from NH) is now about 5' high and has several buds that hopefully will blossom later this spring.


On Jan 15, 2006, Gabrielle from (Zone 5a) wrote:

There's nothing like the scent of lilacs! Make sure and do any pruning as the blooms fade or just after, or else you cut the next year's blooms off. To rejuvenate old bushes, cut back a third of the oldest wood to the ground each year. Don't cut all of the short growth back unless you want all of your blooms up high. My information says that it is hardy in zones 3-8 and that it is okay in partial sun. Stratification aids germination of seeds. Blooms April-May in my garden.

I have very fond and fragrant memories of lilacs from my childhood in Central Indiana. However, I have never heard of dividing the rootball to propagate; I have heard of separating rooted shoots, when one to two feet tall, from the mother plant's roots and of rooting etiolated (blanched by mounding soil or mulch around the shoot) shoots from the roots. New colors, cultivars, can be obtained from seeds.

This plant does very well here, providing the buds don't get froze by a late frost. I grew up in a house surrounded on three sides of the lot by lilac hedges, 100' long on each side. My mom still lives there and the lilacs still bloom profusely (weather permitting ) with virtually no care. They get out of hand on the drive-way side of the property and have to be severely cut back every couple of years inorder to get out of the car on the driver's side. The other sides of the lot haven't been trimmed in years and could probably use it ( we moved there in '63, and the bushes had been there since ~40's-50'ish). Many of the stems have tree-like proportions, but a good trimming would undoubtably bring many more blooms. As it is, in a good year, the fragrance is enough to give you a headache! B... read more

Great fragrance. Shoots sprout up nearby and can sometimes be successfully moved. These also grow wild here in Rochester, NY.

This tree was here when we moved in. It was in tree form just needed pruning round the skirt of it. Flowers mostly on the top now, but lots of them with lots of fragrance. I can smell it in my bedroom window. It is about 8-9 feet tall, it gets partial sun and we have only just pruned it. We didn't know what it was when we moved in, as it was summer time, and we saw its first bloom this spring, short bloom. So now that we know what it is we pruned it and will feed it for I think the first time it ever got fed. Greta color lilac and great glossy green leaves. Zone 6 - NE

Received as a very small offshoot from "wild" lilacs in Illinois, after five years it is eight feet tasll and blooms nicely here in Los Angeles, California. Full sun, well drained slightly alkaline soil, regularly fed and wateed. Suckers heavily. Too short a bloom period in late spring. Lovely aroma. Good cut flower.

Lilac is one of the most notable fragrances grown in the common garden. A single sprig can scent an entire room.

A suckering shrub, it can be trained into a tree form if desired. Most cultivars require cold to flower, southern gardeners whose winters are mild may have better success with other species.
