They could be naturally trailing ones. You can buy bushier varieties, and they're very easy to grow from seed.

Cheers i will look to buy some of the bushier variety.

Remember they are annuals so wait until next year to buy and sow. The ones you have will doubtless self seed and reappear.

Many thanks
Graham.

The none trailing ones do remain quite compact though and do not scramble at all. I haven't seen an in between variety but if anybody knows of one please tell! You'll probably find that the ones you have now will self seed anyway even if you pick up every fallen seed you can find.

Why don't you just pinch out the growing tip of your trailing nasturtiums, Boyce, and that way they'll still trail but will bush out more. Just let some of the seeds fall to the ground and then, like Steragram says, they'll grow in the spring and you can transplant them. Don't leave ALL the flowers to set seed though, as this will weaken the plants ability to flower....Annie

Gosh Annie, I didn't know anything would do that - I just leave mine to get on with it and they go wild.
