Ferruginous Clerodendrum: An Uncommon Tree for Adventurous Gardeners
If you’re looking for something truly different in your landscape, the ferruginous clerodendrum (Clerodendrum trichotomum var. ferrugineum) might catch your eye. This unusual tree brings an exotic flair to gardens, though it comes with some important considerations that every gardener should know before planting.
What is Ferruginous Clerodendrum?
Ferruginous clerodendrum is a perennial, woody tree that typically grows over 13-16 feet tall, though environmental conditions can sometimes result in shorter, multi-stemmed growth forms. As its name suggests, this variety likely features rust-colored or reddish-brown characteristics that distinguish it from other clerodendrum species.
Where Does It Grow?
Originally from outside North America, this non-native species has established itself in several southeastern and mid-Atlantic states. You’ll find ferruginous clerodendrum growing wild in Florida, Georgia, Louisiana, North Carolina, and Pennsylvania, where it reproduces on its own without human intervention.
Should You Plant It?
Here’s where things get interesting – and a bit complicated. While ferruginous clerodendrum isn’t currently listed as invasive or noxious, its ability to reproduce spontaneously in the wild means it’s worth approaching with caution. This tree can be a conversation starter in your garden, but responsible gardeners might want to consider native alternatives first.
Native Alternatives to Consider
Before committing to ferruginous clerodendrum, consider these beautiful native trees that offer similar exotic appeal:
- Flowering dogwood (Cornus florida) for stunning seasonal interest
- Redbud (Cercis canadensis) for early spring color
- Serviceberry (Amelanchier species) for wildlife value and edible fruits
- American hornbeam (Carpinus caroliniana) for unique bark and fall color
Growing Ferruginous Clerodendrum
If you decide to grow this unusual tree, keep in mind that specific growing information for this particular variety is limited. Since detailed care requirements aren’t well-documented, you’ll need to experiment and observe how it responds in your specific location.
As with most trees, providing well-draining soil and appropriate space for its mature size will be important. Monitor its growth carefully and be prepared to manage any unwanted spreading, given its tendency to naturalize.
The Bottom Line
Ferruginous clerodendrum represents one of those garden mysteries – a plant that’s established itself in American landscapes but remains relatively unknown to most gardeners. While it might appeal to collectors of unusual plants, most gardeners will find greater satisfaction (and contribute more to local ecosystems) by choosing native species that support local wildlife and require less guesswork when it comes to care.
If you’re drawn to this tree’s exotic nature, consider it carefully and always prioritize native plants that will thrive in your area while supporting the birds, butterflies, and beneficial insects that call your region home.
