A Quick Word of Caution: Don’t Get Confused!
It’s easy to mix up the Lilac (*Syringa*) with the Butterfly Bush (*Buddleja*), but they aren’t actually related, despite the similar look and name. Another common mix-up involves the Black Elderberry (*Sambucus nigra*). You might wonder why I’m mentioning elderberry here—well, in some regions (especially in Northern Europe), elderberry is actually referred to as “lilac.”
You’ve probably heard of “lilac berry tea” or “lilac flower syrup” and wondered, “Wait, I thought lilacs were toxic?” Here’s the deal: those treats are actually made from Black Elderberry, which is perfectly safe to eat when prepared correctly. So, please don’t go picking actual lilac flowers to brew a tea! Any “lilac tea” you see in a store is definitely elderberry. Just a reminder: not only are lilac flowers toxic, but the berries, leaves, and bark are as well.
