Here's mine.
It is really a challenge........ after lots of consideration - without looking things up in magazines and on the web - I decided that something to ad structure would be more important than beautiful flowers (which I really wouldn't want to be without either)
1. Salix integra 'Hakuro Nishiki' (dappled willow).
It is a small shrub, the young leaves variegated green, white and pink. You can create a small tree working with one year old rods:
A willow can be utilized in many ways using living or dried rods. Hedges, fences, baskets, plant supports, furniture, shelter to name a few. You can also ad some sprigs to alcohol for a nice bitter - which by the way also cures aches and pains as willow contain salicylic acid.
2. Calamagrostis x acutiflora 'Karl Foerster' (feather reed grass). There are so many beautiful grasses - very difficult to pick out one - but blooming fairly early with fantastic colours and the plant's shape and beauty in winter made me pick this one. I bought one plant 4 years ago and today I have about 25 of them simply by dividing the plant every year. Now I'll let it rest to develop larger beautiful clumps.
3. Hydrangea paniculata 'Limelight'. Had to be a hydrangea and this is the one that I know the best, but there are so many gorgeous ones - I really like the blue and purple mopheads and the lacey ones, and how about the oak leafs (but unfortunately they are not as easy-going in my garden climate). The big, long lasting flower heads on 'Limelight' start out a pale lime green and the colour change on the flowers as they mature into deep pink/burgundy and look beautiful until winter.
Sorry, I didn't have any photos from the garden of number 2 and 3, but you can find them on many great websites. My favorite for information and links is: http://www.flower-gardening-made-easy.com/ Yvonne Cunnington's site has beautiful photos and great garden info. and if you are not familiar with her blog, check that out too.
