I have always just thought of the yellow pond plant as a marsh marigold. It grows in my garden borders also as my garden is a swamp for 9 months of the year!
The pink blossom is a weeping ornamental cherry that my mum and dad brought for me when I first left home in about 1994. It has moved around with me and is now permanently planted in our woodland garden. This year it is smothered in blossom and if this warm spell keeps up, the tree is going to look AMAZING by Sunday!
Then there is a rogue hyacinth....don't know where she came from ! I have 4 more to plant up there from bulbs that I brought cheap from the garden centre for indoor flowering.
Beside that is my fruiting cherry...not sure of the type, it is a bright red sweet cherry - a cheapo from Woolies a couple of years back.
The white shrub I can never remember the name of....I always think of it as the bridal plant as it gets covered in little white flowers and the branches are quite floppy in habit so it 'weeps'. Smells like cats pee if you ask me!
Then last but by no means least, one of my fave early flowers, the Dicentra, or bleeding heart. I have a white one also but she is much later to flower.
