Summer of love

These past few days, I've noticed the flowers in bloom. All the rich hues of red, pink, yellow, orange and violet. Especially if you travel along the ECP, there is this type of plant that flowers really magnificiently. When it's in bloom, nothing can stop the array of colours. It's a pretty common plant here in Singapore. You can find it most often at the sides of the overhead bridges. The sad thing is I don't know it's name. It has got very thin branches with thorns. The leaves are light green, almost heart shape. The flowers are pretty fragile and can be crushed easily. Not forgetting the lilies. Wait..... Are there even lilies planted at the side of the roads here ???
