Adenanthos sericeus is called woolly bush, an appropriately named shrub for its fine needles that cover it like a soft, woolly coat. Native to Australia, this bush is a pretty addition to many gardens and is hardy down to 25 degrees Fahrenheit (-4 degrees Celsius). With some basic adenanthos information and the right climate conditions, you can grow this easy and attractive shrub.
water well until established, but ensure that drainage is good as Adenanthos do not like damp conditions, however it does not like long dry summers either.
A few different thoughts on this, tip pruning can be carried out to maintain a bushy habit and this is best carried out in spring after flowering. Damaged foliage can be trimmed back at any time.
Cold hardy to about 20-25° F although tip damage has been noted around 24° F in a central California nursery.
