Experiment

The cottages I clean on a Saturday has a vase of fresh flowers every week. I’ve just brought home the old flowers 
Stocks, sweet William ( I think ) , roses and a yellow feathery thing ( no idea). I was going to try to take cuttings. What’s the chances?

   

It’s only the roses that are looking really sorry for them selves.

Look for little side shoots - I sometimes buy cheap pinks just for those. Might work with the Sweet Williams.
Cut off the rose flowers and poke the stems into a pot of compost - done that too.

You may be lucky - try to get them to provide easy to propagate flowers in future.

It was the roses I wanted to try more than anything. I’ve already got sweet William, voles & slugs like stocks to much . But obviously as they’re here I’ll give them a try.

Great minds.

I've often looked at bought cut flowers and wondered the same. The ones that interest me are mainly the chrysanths and the carnations/pinks in the bunches I buy. Anyone who has had any joy propagating from cut flowers, I would be grateful for your input.

I rarely buy cut flowers, only yellow stickered ones and I'm selective with those. I usually have to explain to someone, why I'm buying a bunch of flowers with dead heads, and they look at me strangely when I say that I want to grow them!!

In a similar vein, I had some lily bulbs bought me and when planting them out, there was quite a meaty looking scale off one of the bulbs. I left it in the bag it came in with the moist compost. A small bulbil soon developed and other bits thickened up. When 2 leaves got to be about an inch long, I potted it up. I've just repotted it as the roots were at the bottom of the pot. There seems to be about 6 separate bulbs developing now.
