"Acanthus mollis, commonly known as bear's breeches or oyster plant, is a herbaceous perennial plant with an underground rhizome in the genus Acanthus. It is regarded as an invasive species in some jurisdictions.

Acanthus mollis is entomophilous and it is pollinated only by bees or bumble bees large enough to force their way between the upper sepal and the lower, so that they can reach the nectar at the bottom of the tube. The fruit is an ovoid capsule containing two to four large black seeds. The dispersal of seeds is by the wind (anemochory).

These plants are usually propagated from tubers and tend to form large, localized clumps which can survive for several decades and look statuesque when well-grown, but its suitability as a garden plant is lessened on account of its invasive nature (new plants are produced readily both from seed and portions of root) and its susceptibility to powdery mildew and attacks from snails."

This plant struggles for me. It emerges late and is highly susceptible to slug damage. Just when I think I have lost it (again), it throws up some rather ratty looking foliage and I try to pamper it to a nice looking plant. I have never gotten a bloom from it. I've seen some gorgeous photos of it, but sadly, I think this is just not a good choice for my Pacific NW climate.

Plant came up this spring after being smothered by English ivy. But the neighbors cut down two large oak trees, removing the shade. The amount of sun was killing it! So I transplanted it into my shady woodland part of my garden.
