Pink surprise

Today I visited my nan and decided to look around her garden. My nan is a big gardener and her garden is always full of flowers (some which she has owned for 15 years!) The last time I saw her garden these flowers had not appeared, but now they are wrapped around an arch over her garden path! I have no idea what these flowers are, but I snapped them as they are a distinct bright pink. I edited this image on my phone to blur out the background and sharpen the picture. :)
