Perfumed flowers to attract bees

[Odsox]

I need some help from gardeners who grow flowers.
I'm trying to grow melons in my greenhouse hydroponically and they are growing very well, especially considering this awful weather we've been having. They are producing masses of female flowers along with male flowers but so far no sign of any swelling into fruit.
I have been pollinating by hand for several weeks but to no avail. What I need to do is attract bees into the greenhouse to do the job properly.
So, what I need is suggestions for an annual bedding plant that is highly perfumed, that is a small compact plant that flowers all summer long. Apparently the plant needs to be a single flower type, not double or multi petalled (RHS) and highly perfumed to attract them to my semi subterranean greenhouse.

Blue, purple, yellow are good colours. Rosemary is a great favourite if you have one in a tub in flower. Calendula (pot marigold which you can eat) or tagetes will help as these do attract pollinators. Lavender if you have one in a tub. Nasturtiums too. All ones that I can vouch for!

Bit late to put in clover now but think of tubs of red clover for next year or even good old white which is also busy on my allotment. My phacelia is full of bees but that's a bit tall for indoors, likewise foxgloves.

One plant that may fit the bill is heliotrope or cherry pie, it flowers all summer long, has a sweet scent and you can also get a dwarf variety, you could interplant it with sweet alyssum which also flowers all summer and can be overwintered and will flower early in the year. I tend to grow phacelia, it really does attract the bees but it does get a bit sprawley in the tunnel

Pot marigold? (Calendula?) they grow so fast you would have a greenhouse full in about two months! Otherwise there is a yellow and white flowered plant a bit like a weed that I can't for the life of me remember the name of - we used to call it the eggplant, but it isn't aubergine. Anyone remember? It grew really fast too.

I think you mean Poached Egg plant, Limnanthes.
Thanks for your suggestions Flo and Bonnie, but what I really need is a plant that is really highly perfumed. My greenhouse is below ground level and not easy for flying insects to get into, which is a real benefit for some insects (root flies) but not for pollinators. I did wonder about Lavender though.
My apricot tree attracts bumble bees wholesale, it has a moderately strong perfume but mainly as it flowers in February it is really the only show in town. In June, July & August it needs a flowering plant with a lot of "pulling power".

Thanks for your suggestion DnD, I've never grown Heliotrope and looking it up it looks like a good candidate.

[diggernotdreamer]

I expect a good garden centre should have some large plugs of heliotrope, they are quite popular

Ah, sorry misread that - yes, smellier the better then. Good luck!

Thought of you this morning as I walked past our lavender hedge...bees all over it!

I'd go with big pots of alyssum. Heavenly honey-like smell.

Funnily enough, we went to Lidl this morning and they had racks of huge lavender plants in 8" pots, so I bought one.
Now transferred to the greenhouse, so we will see ........

[Odsox]

Well it worked
Not the lavender, which I've discovered is only fragrant when you brush the leaves.

tubs of red clover

That's working a treat Flo, but was accidental. I had a trough of strawberries outside since last year and brought it into the greenhouse about a month ago. The strawberries have stopped fruiting now, but huge blooms of red clover have sprung up in the trough and are smothered in bees, even on a gloomy overcast day like today.

I will have to pay attention to companion flower plants next year, not something I know much about so will have to read up on the subject.

There you go, Flo, proof that your suggestion of clover worked.
I now have 6 of them in various stages of growth, but no ripe ones quite yet.

The Lavender was useless.

Hi. I know you're sorted for this year - and very good they look too. I've got sweet peas in my greenhouse. I know they're not the compact plant you were looking for but they don't take up much space if you tie them up the side and they do smell very strongly.

Glad the clover worked for you Thomzo - one of my accidental discoveries over the years. I'll throw you another one - if you grow various herbs for house use (thymes, majoram, in particular) these are also great for bees when they flower. Good in tubs and dual purpose. Perhaps along side the clover you could have a really long season indoors or out.
