Sow now for a riot of colour in June?
I am holding a large garden party on 15th June and would like my garden to be a riot of colour! I have bought a lot of packets of annual seeds - cosmos, petunia, busy lizzie, marigolds etc, but many of them state to sow March - April for flowers in July. I have tried sowing some cosmos on a windowsill in the hope of getting them to flower earlier, but they have come up really leggy and I don't hold out much hope for them. I have a greenhouse but it is unheated. Am I wasting my time sowing earlier? Are there any seeds I can sow now for flowers in June?

If you can afford it, you’d do better to buy a few trays of plants already in flower, they will have been grown in the best conditions light and heat and so on, but mid June is pushing it for any annuals to be at their best.
I grow annuals to fill in spaces later in the year, cosmos will flower from end of July to October.
Commercial growers provide heat and light to make the seedlings think they are in their natural home and season. People like us can do it if we have the money and time but generally, it's easier to buy plugs or flowering plants.
Lyn, your garden is beautiful.
If you can afford it, buy in trays of bedding Begonias, the whites and pinks go well with roses I find, but not the red... and small pots of Nemesias... they were all in full bloom on 8th June last year.. a modest outlay for a riot of colour... Nemesia 'Easter Bonnet' is really very good, and scented too as you walk past...
Foxgloves, which you can buy early in March as leafy plants in pots will be in full flush, as will Sweet Rocket [Hesperis] and Verbascums.. all can be bought at garden centres in early Spring to flower from mid May onwards... another is Geum… the red 'Blazing Sunset' and yellow 'Lady Stratheden'... a few pots of any of these will help you out … best of luck..
