Plants to identify

Can anyone help me identify these plants please. They are both of the same genus, just different colour varieties. I purchased them from an open garden day at a big house but cannot remember what they are. They have grown into clumps about 1 foot high and have been flowering in my gravel garden since June. I shall want to get some next year and so need to know what they are.
Thanks

Mmmm, argyranthemum perhaps? Or some close relative?

 

Well I'd go along with Ivory...the yellow one looks like the variety called 'sunlight.' I have the white one but lost the label.

Think they are classed as a tender perennial, whatever that means. I've yet to see if they die down in winter, or just stay evergreen until next years flowers.

 

They are evergreen if they stay in a greenhouse, I think. A friend of mine had one trained as a standard, and she kept in the green house in winter. I really think it was the same plant.

 

Have to see what the plant is doing outside my doctors surgery during the winter, as they have a really big bunch there (gonna nick some cuttings in the spring) but don't let on eh!!

 

Thanks for the info. As a result I shall dig them up prior to the frosts and nurture them in my low temp greenhouse along with the pelargoniums I have three. White, yellow and a whitish one with a pink blush.

 

I would agree with Ivory and Tweaky about Argyranthemums - thay are lovely and long flowered. In South Devon they can survive outside over winter, but they probably won't with you. They are easy to take cuttings of. I took some over the winter, and they are very healthy and flowering their heads off now.

 

Looked them up on the web. Commonly called "Marguerite's" That name I am familiar with, but usually heard it when listening to ladies referring to bouquets.
