Marjoram grows easily from seed and spreads rapidly - I throw loads away each year. I don't suppose you live near enough to me for me to pass some on to you?
Catmint is, as it's name implies, loved by cats. Whist my cat was alive I had to put a little mesh fence around mine as she would eat the new shoots down to ground level - indeed I first grew it from seed and planted out young plants to create a patch. I couldn't understand how one or two plants simply disappeared each day....until I found my feline culprit. Later she would sleep on top of the plant! Having said that it was pretty hardy and I love the scent when you brush past it whilst weeding.
I have put sea holly seeds in 10 days ago and have about 20 coming up. On the packet it states warm for 2weeks then to put them in the fridge for 2 weeks then back in the warmth and then another 2 weeks chill. ..as they have sprouted and I have got more than enough do I have to go through this chill/ heat cycle?
wuw tanglefoot, you will be busy, i am doing the same thing this year on increasing the amount of flowers i have - tho i have a tiny garden, i have gone and bought over 300 various bulbs for my 2 layered planter, so will hopefully have plenty of bees and butterflies, and sill hopfully be able to supply them with nectar all they way into december .
i'm trying to go for natives where i can, the patch of ground (car space) at the back will be for raspberries, blackberries, grapes, gooseberries, at their base will be foxgloves (native purple as well as white with purple spots) forget-me-nots, marigolds, wild seed mixes as well as being allowed to grow wild with grasses just having a path to each bed for me to walk on I look forwards to hearing how all you're flowers get on, i'm sure you're going to have alot of success
Nobody has mentioned Lavatera, the shrub. Mine was covered with bees and hoverflies last summer as were the geums. My garden is filled with bee and butterfly friendly plants, it's a wonderful sight, I had to get help to count the butterflies last year. Coreopsis is good for hoverflies as well.
If you want the Viper's Bugloss lots of Wildflower sites have seeds but I think the Echium Blue Bedder is more attractive, easy to find from any garden centre or seed site, flowers all summer, and the bees love it. A pretty blue--although I had one white plant pop up last year. It also self-sows. I collected seeds from last year and hope they work for this year. I direct sow them and they always come up.
i pretty much ONLY buy plants that the bees will love, and as a result i see/hear one in my garden every few minutes!! your list is great!!
for EARLY spring flowering (FEB-MAY) i def recommend Cowslip (my profile pic) & Lungwort (Pulmonaria - available in various colours and good in shade, see below pic), and for summer Cerinthe Major aka Honeywort - full of nectar as the name implies and it looks cool

I love encouraging bees and got most of the above in the garden.. cosmos is a big favourite with the big fat bumble bees too

Tanglefoot Twitch, the pollinators will indeed love your Vipers Bugloss I've grown it for them and they were on it all the time.
