Pincushion Cactus
Q.

Will Calocephalus grow outdoors in Ireland as it is a South Australian plant.

Zone E91EW95 | MaryJo added on March 19, 2019 | Answered

Currently I am using it as an indoor plant for flower arranging. When I purchased it the foliage was pale green and then turned silver as though dead. I purchased three further plants two of which went the same way. The third is continuing to produce new shoots. I use for miniature flower arranging as the plant material remains turgid out of water.

It will only survive down to 33F (1.1C) or so. If it goes below that in your part of the world, then you won't be able to grown them outdoors, however a container grown specimen might be possible.It also needs to remain very dry, as they are not tolerant of moist soils.
