I have been growing verbena, echinacea and delphiniums from seed. They are in an unheated greenhouse.I am about to go away for 3 weeks and was going to take them to a friend to look after. My question is would I be ok to leave them outside or will they still need protection. Pls see the photos for the size of them. Thanks

Delphiniums Echinacea Verbena



If those Verbena are bonariensis, they'll die over winter outside - keep them in the greenhouse over winter and hopefully they'll make it through.
As for the others, they'd need hardening off before being left outside all the time, and the delphiniums look a little too small to do that with yet.

I would say it depends on the forecast, if it is fairly mild then they should be ok.

Personally, I would gamble and leave them where they are.It's unlikely to be a drought situation now, so protect them from any frost and go and enjoy your hols.

Grannyb, it sounds like the problem is that the friend doesn't have a greenhouse, or access to Pdb's. The Delphiniums will probably have to go indoors in a sunny window, but three weeks is pushing the envelope for keeping D's indoors. I would expect the other two to go outdoors, as long as they are in a sheltered area, and the weather isn't too cold. If the friend can bring them in at night, that's all to the good.

Many thanks for your replies. I will keep the Verbena here and put them outside in a sheltered spot and take the others to my friend. They do have a greenhouse so they should be ok. I also have quite a few cuttings that I am experimenting with and will keep those outside also in a sheltered spot. Not sure how they will go on but I will have the spring to try again.

When you get back from your holiday, pinch the verbenas back to a leaf axle to make them nice and bushey.
