Yes, herbaceous perennials go right down in the winter, and then erupt in the spring to give flowers in the second year,usually. Thompson and Morgan have a list of first year flowering perennials, but you have to get them in early for them to flower the first year. Better to sow around now, and produce a strong plant to overwinter. Sometimes it takes three years. I have Inula  and Michauxia just starting to flower, from plants grown two years ago.

Well, you see FB I don't have much patience and that's where I would get fed up with waiting!

I think I've decided on that Scabius type plant, Sweet Williams and Foxgloves or Lupins, don't want both so I need to decide on one of them.

Thanks all

I'd go for foxgloves, something always eats the lupins

29/05/2014 at 22:07

I'll take a picture tomorrow, provided its not hissing down again.

29/05/2014 at 22:08
Right, that's decided then.....Foxgloves, Scabius type plant and Sweet Williams. I also have Delphiniums, Coreopsis, Geum and one other that I can't remember the name of all in pots....so that's 7 types of perennials altogether plus the ones already in

I'm waiting for some perennial sunflowers to flower from last years plants. (helianthus laetiflorus). Now, what to choose for next year... I think I need some  Campanula pyramidalis,I seem to have lost all mine when I cleared a bed last year.

Penstemons are fairly easy from seed too, but the bigger flowered ones aren't always hardy.

I've googled them Lizzie, they say late summer flowering, now there's something I hadn't thought of, if I want colour all summer I either need plants that produce flowers all summer or some that produce early and some late??

I knew it wouldn't be so easy!

I've grown some Wallflowers from seed this year OL. A mix of yellow,deep red,bronze and a creamy pink.Very easy to grow,tough as old boots and best of all the slugs don't like them,at least not mine anyway.

Annuals flower all summer then die. Perennials have shorter flowering periods and some flower early and some flower late, but they will come up the next year and provide greenery, texture and form in your flower beds. Dead heading keeps many plants going for longer and some plants like certain perennial geraniums and catmint (Nepeta) can be sheared right down and they will re grow and re flower - but not as well as the first time.

I grew monarda didyma  last year and was so pleased that I'm growing some more. Last year's have come up again too! They have lovely exotic flowers and bees love them - I think they are called bee balm too. Dead easy to grow.

It should'nt affect the choices you have made OL but not all perrenials are consistently longlived, often plants listed as perrenials have a life span of only 3-5 yrs

Its worth 'googling' online, there is lots of info there, specialist nurseries will give advice but lots of general GC's list all plants the same, so you may buy a plant thinking it will be a permanent fixture only to find it dies within a couple of years

 Knautia macedonica melton pastels.

 Grown from seed last year. They may only last a year or two , but I can take seed off them later on in the year.

FB ,I sowed seed of Knautia , eryngium and hordeum last August and also in April to see which fared better. I'd say those sown in April ( in a cool polytunnel ) have caught up with those planted last August.

The hordeum jubatum had almost 100% germination and look like they'll flower this year.

I have a Knautia, but it's dark crimson. It's seeded itself, but the original plant is still there after 4 years.

The other perennial you can grow from seed are hardy geraniums . I grew a dozen or so from a packet of mixed geranium seed from plantworld.  One small purple one flowered the first year, most in the secong year, and this little beauty this year.

I like those geraniums fidget, I got some free from GW mag and can't believe how much they have grown.  I would like some different colours though so that's a good idea 

25/06/2014 at 22:26

Another questions - Cineraria, has anyone grown them? They look early pretty but nit sure from the info of they are a houseplant?

03/07/2014 at 21:47

Ooh those Knautia are delicious. They look like Scabiosa to me. That is, the lovely wild lilac ones that are growing in the A500 verges near me! I will look them up
