Lilacs are a lovely and beautiful plant, however they have a short and disappointing blooming season. There are some plants for your garden that can help fill the gaps caused by this. Some choices of companion plants for lilacs include spring-flowering bulbs, flowering shrubs, small trees, as well as some lightweight vines.
Key Takeaways:
- When it comes to companion planting with lilacs, spring-flowering bulbs are among the top choices for many gardeners.
- Bulb plants like daffodils, tulips, grape hyacinth and peonies multiply and naturalize
- Pick shrubs that blossom at different times so that you can have several months of lilacs instead of only several weeks.
“For more adventurous companion planting with lilacs, allow your lilac tree to serve as a trellis for light vines. If you plant a lightweight vine like clematis, it can scale your lilac without hurting it. The great advantage is that clematis blooms after a spring-flowering lilac is already done.”
