I have grown them in the past in a large pot (but then, I grow nearly everything n pots so that doesn't say much really!), I used a mixture of JI2 and general purpose compost, gave them a reasonaby sheltered spot, they do come from the tropics, and they flowered fine for me. If you did chose to do them in a pot, you may be able to keep them over for a second year, but I did not take mine inside so they did not survive. Lots of very pretty papery petalled flowers, varied colours - nice.
I've never kept the tubers, they're so quick and easy from seed and produce plenty of seeds so I keep them going like that. Less trouble to store seeds than tubers. Sorry Swedboy, not answered your question on when to plant. I'd get them planted, if a frost is forecast you can always cover them with some newspaper, there won't be a long penetrating frost now.
I have just bought a packet 3 tubers of mirabilis perenials please can you advise which way up do i pant them they'r still in bag but look cigar shape. am new to gardenig.
I bought a pack from Poundland last month, I planted them into pots & placed into the conservatory so far 2 of them have new shoots appearing.As for which way up to plant ,I found that 1 end was more rounded than the other so I kept the rounded end up.
I agree Mike, the seed started ones are very quick indeed, large, easy to prick out seedlings and no messing about looking after tubers through the winter.
Never has aphid trouble though
Saved some seeds from last year so I better get sowing. Slightly disapointed that mine didn't smell much. That was my reason for buying them.
Dug one tuber up and left the others behind. Suspect they have drowned now...
Plenty of time to sow, I do mine about now. Except that I forgot to save any last year.
Thebest scent is in the evening as with many plants.
I sowed my mirabilis and they broke the soil in two days they have got to be one of the quickest to germinate I've sown. Does any one know any other plants that germinate fast?
When can you expect the tubers to spring back to life again. The ones I had seems to have survived winter well have been back in the soil two weeks or so but no life from them. I am probably a bit impatient as I am eyeing up the pots for something else if they don't come back to life soon.
(had a littel dig about and the tuber looked fine but no growth.)
