it certainly does although it does sometimes lose all it's leaves if there is a very harsh winter but when that happens it seems to flower more profusely the following year. it appears to be a very popular tree in the village of rhu i've counted around 30 almost as popular as laburnum.
Is the wikipedia entry accurate in that it doesn't tolerate phosphorous ??
As far as I know some members of the Proteaceae family live on low/poor phosphorus sites that may explain the Wiki reference. The soil where it grows is very probably quite acid that causes the element to be leached out of the soil very rapidly in nature.
