There is something that warms the heart about Bougainvilleas, especially when in full bloom, and even more so in a sunny day against a white backdrop.
With their bright color and need of hot sunlight, they unerringly bring Keats to mind when he sighed after a Nightingale and called:
O, for a draught of vintage! that hath been cool’d a long age in the deep-delved earth, tasting of Flora and the country green, dance, and Provençal song, and sunburnt mirth!
Exactly what I feel when looking at Bougainvilleas.
