    My shrub is about five years old now, and loaded with flowers. It does have a wonderful fragrance, bloom lasts a number of weeks. I've seen multiple Humming birds around it many evenings, butterflies as well. The form (so far) is wide and spreading, so give it room. This year I have a ton of seedlings underneath. it may be best to keep it mulched and only have spring bulbs underneath, so you can easily keep up with seedlings and suckers. After flowers it has beautiful purple and pink berry clusters. Leaves emerge late in spring, don't panic when it is bare as many other things leaf out.
    It's now November, and this is mobbed by bluebirds! They must be eating the berries.

    I adore this shrub at least as much as the hummers do! That said, I STRONGLY advise planting it in the middle of a grassy area that you'll mow around, in order to keep the root suckers in check. Mine is maybe 12 feet tall, with 3 main trunks that are 2 1/2 - 3 inches in diameter. It's sending out shoots at least a dozen feet from the parent plant. Lots of shoots. I tend to ignore them for a year or two (they aren't really in the way) and then dig them up to share... Just loosen the dirt and pull, then pot up until they grow a nice rootball.

    Absolutely adore this shrub (more like a tree, though, size-wise). Its wafting lily-like scent fills the yard from July through Sept...sometimes early October. The hummingbirds and butterflies love the blooms. It does send up some suckers, but they're easy to recognize and can be pulled up with minimum effort if done so when young.

    The Royal Horticultural Society (RHS) gave its prestigious Award of Garden Merit (AGM) to Clerodendrum trichotomum var. fargesii, which is botanically synonymous with Clerodendrum trichotomum.

    'Fargesii' is apparently a bit more cold hardy, and has a somewhat more compact growing habit, so may be worth seeking out for cold climate gardens.
