Topic: verbena bonariensis

My verbena has new shoots sprouting off last year's growth already. I was planning to cut all the old growth back to ground level when it was getting a bit warmer. But now - am I going to have to leave the old growth?

Confused.  ???

Remove last years flowering stems, vut back to ground level.

Leave the new shoots, these will flower this year.

They should be hardy down to about minus 5.

Mine are doing the same and have been in the garden for about 5 years now, self seed all over the place as well.

I like Vebena Bs. Have loads grown from seed a couple of years ago. Strangely though never yet had any self sown ones come up  ???

Hi Aquilegia

My verbena B is growing like weeds!  I cut it back every year to the ground and it self seeds everywhere (Garden Cadet, I've got plenty of seed if you want to throw some around).

I think this year I will get rid of the lot and try something less invasive.

Thanks loz but I have plenty of seed (in packets sent free from various sources  ;D)

I am sure there are plenty of seeds from my plants , lurking in thr soil ready to germinate in spring  :)

It is not invasive if you use the hoe, I am waiting for my first invasion to take over a little used corner.  It is my second season in the new garden and have left them in along with some crocosmia lucifer. I might put some white anemones in as well and show the flag.

Try the verbena rigida which is a lot shorter and grow it amongst some ceneraria and cut the yellow flowers off, the grey and blue go together really well and the neighbours are really amazed at your new 'variety'.
