Blue Asters

I'm looking for blue (not purple) small, daisy size blue asters but can't seem to find any anywhere.  Looking online I can't tell the size as all pics are magnified.  I just want some the size of small common daisies.  Can anyone help me?

    Check out Aster Little Carlow the flowers are about 2cm across. 
  • Aster x frikartii 'Monch' is worth a look.

  • Look up Felicia amelloides aka Aster amelloides aka Aster coelestis aka "Blue Marguerite".

    A trowel in the hand is worth a thousand lost under a bush.

    Aster Little Carlow-
    It's planted at the back of the border, but flopped forward - as it usually does.

    If you want smallish annuals to grow fresh each year, maybe Swan River daisies (Brachsycombe). I have a mix of blues and whites this year, grown from a 25p pack of seeds from Wilko, but you can probably find single colours if you hunt around and maybe pay a tad more.

    I suspect you want a really clear blue, and not the purples that are described as blue.  As shown above, all the asters described as blue are really purple.  For real blue(but theses are not asters), I like the old fashioned Centaurea montana, and Salvia patens which looks like blue velvet.
  • Catananches have daisy flowers in a good mid blue too.
  • Thanks for all your kind replies.  It looks as if the Aster Little Carlow is what I'm looking for as in Pete 8's picture.  

    Regards to all.

    A good choice, but they do need some support as they get to about 4ft or so and rain and gusty winds soon cause them to collapse - but they still look good.
    Very easy to divide the plants to increase stock too.

    Hi @curiousfox.c and welcome to our forum discussions.
    Not technically an aster, but in the same family I would suggest a plant which seems to fit the bill. Kalimeris incisa ‘Blue Star’. I discovered and planted 4 specimens last autumn, which have nicely developed and even self-seeded. Average clump in my garden is about 20cm high x 25 to 30cm wide. Flowers look like smallish aster flowers, between 2 and 2.5 cm wide. Colour is violet-blue, so maybe not pure blue enough for you. More about this neat little plant on my garden site at
