I see our misnamed plant now has flowered, so finally we should be able to ID it.

This is in the Daisy (Asteraceae) Family! In fact, it is a Senecio, or possibly the closely related Kleinia. But we don’t know the species or cultivar.

We may choose to call it Senecio “Frosted Lightening” for now, until we come up with a more proper name. Do you have anything to add?
