Oh wow, only 5 ?
it'd have to be:
paeonies - only just getting into them, as I normally like small flowers, but these great blousey ones are just great. I've gone from having none to now having 6 ready to plant out.
hellebores, amongst the ones I have, one is lime green and I love it !
snakes head frittilaries - I had to leave the ones I had at my last house, as I couldn't find the bulbs in the ground, should explain, I stripped my garden of plants and brought them ALL with me
erm, next I guess would be an old type rose, taking me back to my childhood, I have a lemon coloured one in the garden (that I brought with me) and it actually smells of lemons, wonderful,
and finally, I think it would have to be lavendar, as my Mum and Dad had a massive lavendar bush in the front garden when I was a child, and I don't think you can beat the relaxing calming smell of it.
and as everyone else seems to be sneakingly adding others, can I add double snowdrops and aqualegias ? I had a lovely pink and white grannies bonnet one, and a lime green one which have disappeared over the years, but now I have purple ones, white and purple ones, and my red and yellow one has gone all red and raspberry this year ?? confused.dot.com and also the garden I've inherited since moving in December has just thrown up a lovely fussy flowered aqualegia which I reckon must be called raspberry ripple. My signature picture is of it in its infancy, as I loved the lime green of it, but now it's all raspberry ripple, pink, green, and white.
