Hi

I'm a total novice, but decided to grow some seeds 2 years ago. Some were
ok, others didn't appear at all, but one was a complete success. It was
Thompson & Morgans Achillea millefolium Summer Pastels. You simply couldn't
go wrong. Every single seed germinated and flourished and they have made a
lovely bright spot in the corner of the garden.

I'm now having another look at seeds and want more like this. Totally easy
to grow, the sort you can't kill. Don't care if they spread like wildfire -
so much the better. I like cottage style, with really soft pink blue and
white, and lots of soft green. Is there anything like nasturtiums, but not
bright yellow or orange?

Not in the least like nasturiums, but:
Love-in-a-mist Nigella damascena - pale blue, lacy foliage, flower
appearing in the middle of a lacy haze, followed by big round seed pods
Clarkia - spikes of double white or pink flowers
Alchemilla mollis - big soft green leaves, tiny lime green flowers in
clusters - if it like your soil it will take over ;-)
Nicotiana - tiny seed, scatter it on seed tray, plant out the many
thousands of plants by the clump when they get to about 2 inches high -
best (IMO) have white flowers with strong fragrance in evening
Night scented stock - pale mauve, not much to look at, but again lovely
evening scent.

Shirley poppies for scattering in abundance on bare soil

Perennials to look for (you can buy plants or seeds)
Centranthus ruber - red valerian - available in pink or white. Comes up
every year with fresh green leaves and big heads of tiny pink or white
flowers - self seeds well
Lychnis coronaria alba - downy grey leaves, spikes of white flowers the
size of a 1p piece
Hardy geraniums - buy the odd plant to start with as they're not quite
foolproof from seed.

Chiltern Seeds are a very good source of seeds, and also do some nice
mixtures. Don't worry about things not coming up - I've been growing
things for 40 years, and still have spectacular failures.
