Verbena bonariensis

| How long does verbena bonariensis take to germinate? I seem to be having a disaster with mine this year.
I planted some seed in February, but not a single one came up. I used seed that I harvested in January, so perhaps it had become a bit mouldy on the plant over the winter. It looked OK though.
Two weeks ago, I started again with seed from a packet, but nothing has germinated yet. Am I being a bit impatient?
I grew this plant about five years ago, but I dont remember having any trouble then.

| I have a feeling that verbena seed germinates better in the dark. Also your plants from last year should grow again if they were'nt frosted too badly in the winter. |

| If you're in SE England, you should find that the seeds will have germinated in the soil about the plants. They do here in North Lincolnshire. For my established plants, I cut them down to about an inch above the soil about January time and they are now shooting again. This is after being covered in snow for a week and several hard frosts. I've wondered if the good drainage of our sandy soil has helped them to survive, since the roots won't have been waterlogged over the winter. |

| Have patience. I did the same a couple of years ago. Then I saw that cold stratification for 2 weeks helps, so I put the tray in the fridge for 10 days. It still did not germinate so I put it on one side to throw out. A week later I went back to throw it out and every single seed had germinated, there must have been a 150% germination rate! I love the plant, and once established you keep finding seedlings everywhere, but all very welcome. They are supposed to be short lived but all my original plants are still going. I tried to grow Verbena Hastata the next year and the same thing happened, but I did not persist and chucked it all away as I had too many plants of all types by that stage. |

| Peter did you expect it to germinate in the fridge? A lot of plants like a cold damp period but then germinate when temperatures are raised, which is what you obviously did. A few plants , such as Allium christophii will germinate on damp towel in the actual fridge. |

| Hi Geoff No I did not actually expect it to germinate in the fridge, I left out the fact that it was 2 weeks or so later with no signs of germination that I gave up hope. Only to find my honed skill of procrastination triumphed yet again. But I was interrested in you comments on Allium Christophii. Again I put them in the fridge but nothing happened. As they were my own seeds, not purchased, I probably chucked them away too quickly. If I had paid good money I would have persisted for longer. I shall try again. |

| The instructions that came with my RHS seeds said that Verbena needs 2 weeks cold stratification, then move them somewhere warmer and wait...and wait! They were the one batch of seeds I didn't actually try because by the time I got around to it last year's verbenas were putting on great growth so I thought I'd see what they did for a second year. They also said that the Rudbekia needed cold stratifying, but they came up fine without (I forgot!). Echinacea has been my big no-show this year, 0% germination...dunno what I did wrong :( Alcina |

PeterLS i have just blooked up Allium Christophii in Norm Deno's book and it says dry storage4 at 70 kills the seed so best sown fresh and germinates AT 40 so that is why it germinates in the fridge. Norm Deno's books are very useful. using that I was able to get aquliegia fragrans to germinate - it needs light. |

| Does it take from cuttings? |
RE: Verbena bonariensis

this is a great plant! & one plant planted in a sunny spot (especially with gravel around) should give u all the plants u will ever need as it self-seeds prolifically. i'm hoping the beautiful hastata roseas will do the same for me next year... |
RE: Verbena bonariensis

This self seeds with enthusiasm in the gravel drive at the side of the flower beds. So I just transplant from there with no trouble. It does not self seed in the flower beds though. I am not sure if that is a good thing or a bad thing. 'a 150% germination rate!' Is this a genuine miracle? Or do we just not do maths around here? ;-) |
