Have you been feeding them a lot. lots of foliage is often caused by feeding. stop feeding etc and hopefully the plant will 'think it needs to set seed' and so will flower for you.

I agree with Sbg, a lot of plants are ruined by over feeding, if you plant in multi-purpose there is usually enough nutrients for 6 to 8 weeks of growth, john innes longer than this, take no notice of the manufacturers of the likes of miracle grow, they just want to sell their products, Derek.
