I would like to grow these from seed and would like to know if plants will flower in the first year. Any suggestions about other tall, airy perennials  that easy grow form seed would be much appreciated.

    I've found it takes a few years before they flower from seed.
    I have several that have been in my garden for many years and seedlings appear most years.
    The 1st year they get to about 1ft with maybe a tiny flower spike.
    2nd year they get to about 3 ft with a small spike
    3rd year they're around 6ft with a good flowering spike

    One of my favourite plants- there's a seedling at the bottom right of the pic just beside the plant. It's about 1ft tall

    Verbena bonariensis is easy and will flower in the first year.

    Thank you Pete. The Thalictrum in your garden is stunning. I think it's an exquisite flower. 

    I have one mature plant which I picked up in an end of season sale. I would love a few more. However, they are expensive. But growing from seed will require patience...

    Thank you for your reply Alan. I have Verbena Bonariensis and want a similar airy companion plant with it.

    When I last grew then from seed they flowered the second year.

    Wow! that's good to know. I might buy some seeds then after all. Thank you. Do you have any advice?

    Pete's planting is always an inspiration.  @Pete.8  - is that a Hydrangea paniculata in white?

    Thanks Fire - I'm not much of a planner, I see something I like and buy it then work out where there's a space for it :)
    It's a Vanille Fraise, I've got a few around the garden - lovely plants

    I put in a Hydrangea Magical Moonlight (paniculata) last year, next door, and it's doing so well. So lovely.

    WOW those flower spikes are huge @Fire and I love the hint of lime too.
    I'm going to have to try and find another space! :)
