Oh dear, plants stir up such strong emotions! Here goes- I dislike impatiens, begonias, pampas grass, chrysanthemums, crocosmia. I'm sure they have their place but not in my garden. But love dahlias as my gran had them in her small garden. Pansies, roses, heliotrope as they smell wonderful and who can resist the fragrance of lilac or hyacinths. I love foliage plants, too - heuchera being my favourite at the moment. I could go on...!
