Viola Flowering period ?

I have some Violas in a small strawberry planter , just starting to flower nicely now . Normally I discard my pansies and violas in May when I am planting up my containers . But how long would February planted violas bloom for ? Would they flower through until October, with regular dead heading ?
I used to buy a lovely trailing Viola called Friolina® which bloomed all summer , I can't seem to find it for sale these days.

TIA

 

Violas usually flower for quite a long time....varieties differ. Dead-heading prolongs flowering. When it's clear floweriing is less prolific I cut all flowers and foliage back hard, feed, water and expect flowers again a few weeks later. However, I also use this time to split my plants, pot up and plant out again when it has recovered.

 

HarryS just checked it out and Unwins sell this viola.

 

I think they would continue to flower right through Harry will regular dead heading i understand they like cooler conditions so with our summers the way they are there shouldn't be a problem....i've had them flower right through before
i'm sure i've seen Friolina mail order from Unwins.....

 

They self-seed easily in my garden and can flower till late autumn if I dead-head them. But they do develop powdery mildew from August onwards, as a result most of them get discarded by September. Yet new seedlings emerge continuously until frost arrives.

PS: as they self-seed they come in all kinds of colours and sizes, very colourful.

 

Thanks all , I'll leave the Violas in the strawberry planter all summer and see how it goes . The spot I use for this only gets the sun until 12 , and I am an avid deadheader , find it quite pleasant not a chore ! So now only time will tell - watch this space next October
