Protea "Pink Ice" flowering in my garden

When I moved to Robertson I was aware that the rich red basalt soils here are good for growing Protea plants and their relatives, such as the native Waratahs. The reason I knew this is that the plants I was intending to grow here, Peonies, grow really well in Monbulk, in the Dandenong Ranges (Victoria). Monbulk is famous for its rich red basalt soil - just as is Robertson (in NSW). Monbulk is home to Australia's largest specialist Protea propagation nursery "Proteaflora".

So, naturally, as I was establishing my garden here, I planted some of the members of the Protea tribe - Leucadendrons, Proteas, Banksias and Waratahs, and Grevilleas. This was largely an experiment, to see how they would grow, for some, especially the Grevilleas, are said to be very fussy about soil, preferring poor, low-nutrient soils. But most have done very well indeed. Some have exceeded all expectations, notably the Banksia "Giant Candles" which has had to be beheaded several times already to prevent it outgrowing its roots, and suffering wind damage.

The reason for the "caveat" about the soil is that very few members of the Proteaceae tribe grow here naturally - but members of this tribe of plants are very common just a few kilometres from here on the sandstone plateau below the Robertson range. It seems the reason is that the local rainforest plants survived so well, prior to European settlement and clearing of the land that the native Proteaceae never got a chance to "invade" the basalt. There are only two exceptions to this principle that I know of - a Helicia (of which there is but a single specimen left, apparently), and the tall rainforest tree Stenocarpus salignus.

One of these plants which has done particularly nicely, and grows only at a moderate rate, has turned out to be the popular hybrid Protea "Pink Ice". I bought my specimen Protea "Pink Ice" from Wariapendi Nursery at Colo Vale, NSW (near Mittagong), one of many nursery outlets for"Proteaflora" plants in NSW.

Here are the results:

A bud just starting to develop.
The black marks on the outer sheathing bracts are distinctive
from a related plant, Protea neriifolia, whjich is one of the parent plants to "Pink Ice".Here is the next stage of development of the bud.
It is very elongated overall, and narrow in the tip.
There are many black fibres in the tip of the bud, at this stage.
As the flower opens, the top broadens out.
Suddenly the profile of the flower changes, just as it opens.
It is almost "square cut" at the top, with masses of silvery fibres.
Here is a top view of the flower.
You can see what I mean about the silvery fibres.
This flower has not yet opened fully, but I would have to say that
this is my personal favourite stage of development of the flower.

There is one further stage of development, which is yet to occur. So I will show the fully opened flower shortly (when it opens). The flower becomes chalice-shaped.
