Micki,

No, not any time soon, I'm afraid. If you grow it outside it will stand a greater chance of getting tall (and mature enough to flower sooner) - pick a spot that's warm and sunny, if you can. If the pot rests on concrete (which gets warmed by the sun), so much the better. You'll want to gradually increase sunlight on this plant until it's full sun, a process that takes about two weeks. Luckily, it should go out soon / now for you, if temps are consistently in the 10C range at night and warm during the day.

Hi cactusmcharris, thank you for your response.

Unfortunately, I do not have a garden anymore :( Just two large south facing windows, which is great on a sunny day, although not a reliable source in the north of England!

I did have them in the greenhouse for the last few summers, in my old garden, and they loved it, so it does worry me now that they'll never mature to flower.

Would artificial light help to stimulate maturity and flowering? As I am considering investing in/making a sunlight top up chamber, for the darker weather, but would be restricted to 250w power.

Again, thanks for your help :)
