If you mean Physalis, they're not bulbs, they're roots.

Brill, i just brought some, put only had a bag of soil, with what looked like 4 very thin sticks in it, was that thr roots?

Yep!

Brill,Thankyou very much, Bamboo.

Easy to grow, just like tomatoes.
However you need to grow at least two as they need to cross polinate.

Thanks stjohn, do i need to start them indoors first.

I wouldn't, I'd pot them up and either place in a cold frame outside or against a wall of the house in a very sheltered spot, where you can keep an eye on them - once grown, plant out later (but be careful where you put them, the roots can be pretty invasive)

ok, thankyou very much:-)
