Can Lilacs Bloom Twice A Year?


Lilacs are beloved flowering shrubs that bring color and beauty to gardens around the world. While they are typically known for their single spring bloom, some varieties have the potential to bloom twice in one year, providing gardeners with an extended season of color and fragrance in their garden! In this article, we will explore the phenomenon of double-blooming lilacs, discuss the different types available, and provide tips on how to care for them so that you can enjoy their flowers for as long as possible!

Why Don’t All Lilacs Bloom Twice A Year?

The primary reason why not all types of lilacs are capable of blooming twice is due to their genetic makeup and life cycle. Most varieties produce flowers on old wood from the previous season, which then dies off after flowering and is replaced by new growth from the current season’s buds. This means that if you prune your lilac too late in the season or don’t prune it at all, you won’t get any flowers because there won’t be any old wood left over from last year’s growth!

Different Types Of Lilacs That Can Bloom Twice A Year

The most popular type of double-blooming lilac is the Bloomerang® variety, which is a re-blooming hybrid that was developed by crossing two European species: Syringa vulgaris ‘Alba’ and Syringa vulgaris ‘Bluebird’.

This variety is known for its abundant clusters of fragrant white flowers that emerge in late spring and then again in early summer before taking a pause until fall when they will bloom again until the first frost!

Benefits And Drawbacks Of Having A Lilac That Blooms Twice A Year

The benefits of having a re-blooming variety are obvious: you get an extended period of beautiful flowers throughout the growing season! However, there are also some drawbacks to consider before purchasing one of these varieties, they tend to produce fewer flowers than traditional single-flowering varieties because they put energy into flowering twice instead, and they may require more maintenance (pruning/fertilizing) than other types due to their increased need for nutrients due to their extra flowering period.

How To Care For A Bloomerang Tree

Caring for a Bloomerang® tree is similar to caring for other types of lilacs but with some slight differences due to its unique needs: it should be planted in well-drained soil with plenty of sunlight (at least six hours per day) and given regular fertilizing throughout its growing season (spring/summer/fall).

Pruning should also be done regularly (at least once every two years) to encourage new growth and keep it looking its best! It’s important to note that this particular variety may require more water than other types so make sure it’s getting enough during dry periods or drought conditions.

Tips For Planting And Pruning Your Tree

When planting your Bloomerang® tree, choose an area with well-draining soil and plenty of sunlight (at least six hours per day). Dig a hole at least twice as wide as the root ball but no deeper than it was originally planted in its nursery container.

Once planted, use stakes or trellises for support if needed, this will help keep it upright even during heavy winds or rainstorms! Pruning should be done regularly (at least once every two years) both before and after flowering, this will help remove any dead or diseased wood while encouraging new growth each season!

Techniques To Ensure Successful Blooms

In order to ensure your Bloomerang® tree blooms successfully each year, there are several techniques you can use: provide regular fertilizing throughout its growing season (spring/summer/fall), water deeply during dry periods or drought conditions, prune regularly (at least once every two years) both before and after flowering, use stakes or trellises if needed for additional support, mulch around your tree’s base with organic material such as grass clippings or composted leaves during fall months – this will help protect its roots from extreme temperatures while providing additional nutrients as well!

Common Mistakes When Caring For A Bloomerang Tree

One common mistake when caring for a Bloomerang® tree is not giving it enough water, without proper hydration during drought periods or dry spells, your trees may not flower properly or at all!

Another mistake is not pruning regularly enough, without regular pruning both before and after flowering your tree won’t have enough space or energy to produce an abundance of blooms each season!

Lastly – make sure you’re using organic mulch such as grass clippings or composted leaves around your tree’s base – this will help protect its roots from extreme temperatures while also providing additional nutrients throughout its growing seasons!


In conclusion, double-flowering varieties like the Bloomerang® can provide gardeners with an extended period of colorful blooms throughout the growing season if cared for properly! With regular fertilizing, watering, pruning and mulching – your trees should provide plenty of beautiful clusters come springtime through falltime each year! So go ahead – give your garden an extra dose of beauty by planting one today – you won’t regret it!
