How many flowers /spikes per lupin, delphinium, echinacea?

AstroAstro Posts: 357
I have grown some lupins from seed and bought some potted plants, what I don't know and can't seem to find the answer to is how many flower spikes each plant produces?  Like is it one or multiple?

 I assume multiple but would prefer to know early so I plan to buy more if necessary. I also wondered the same for delphinium and echinacea. Thanks

    I couldn't tell you how many (this likely depends on various factors), but it is multiple. I wondered exactly the same thing last year, and was pleasantly surprised!

    Here is a pic from my lupin border from last year. This is 5 plants that all went in around early May, and this was probably as many blooms at one time as I got - but they kept coming for a while as individual flowers finished:

    depends on size, age, soil, water

    Wow very nice , those five plants filled the space well. This is good to know as I bought in one's and twos of different colours and they otherwise might have looked bitty. The ones from seed I'm not even counting on being ready this year. 

    Thanks for the information.

    Lupins can get a few-



    That was last June, had only been planted the previous Autumn. It's already bigger than that this April so hopeful of even more this year.

    Remember to cut the spent flowers off and you can get a second flush of flowers. That one ended up flowering right into late August for me, was well chuffed. Sun all day and dry soil.

    I haven't grown Delphiniums but they should be cut right down to the ground after flowering AFAIK to get a second flush.
  • My garden soil is very poor in spite of adding compost etc and it is difficult to get many plants to grow well.  Those that do grow well do very well and I have great results with Lupins.  They seem to be at their best in the second year and tend to peter out after about 3-4 years.  I always have young plants grown from seeds to replace them.  You will love the plants in full bloom - they can be spectacular!

    Nice, Dirty Harry, was that just the one plant? Looked happy long may it continue.  

    Christine it's good that although your soil isn't 'perfect' you've had great success with lupins. I will look forward to seeing how mine turn out 😊
