I still find these beautiful viola Floral Powers popping up unexpectedly - one of my better results with seeds. I first planted these two years ago. I see they are described as perennial and although I have them self-seeding I wouldn't call them perennial.
I love pansies (and violas) and find them not too difficult to grow from seed BUT the colours all seem to be the same - all I seem to get are reddish and yellow. Last year I had the same and these are from packets of mixed colour "Swiss Giants". Most of my nigella flowers are boring white (pic to follow) so I'm beginning to think the seed suppliers are filling out the mixtures with the most boring colours. I'm going to try some single colour selections of pansies next time.
Some things do seem very difficult to grow from seed so I'm grateful for the odd easy packet of seeds such as these marigolds that came free with my seed order. It's reassuring I can grow *something* from seed. As usual with just about every pot in my garden, something has self-seeded itself in it, in this case aquilegia.
