Newish To Gardening Candytuft in my bed Questions

Flowerina

Hi everyone, 
I have a few questions.  Actually, I have a hundred questions but I will only post the one I'm most concerned with now. 
My front porch bed has a row of 6 knockout roses with Royal Candle Speedwell in front of them (just planted).  I want to plant a row of candytuft in front of the Royal Candles. I bought 8 candytuft and someone told me that this is way too many for my garden bed.  The Candytuft has a spread of about 18" so if I plant it around 18" in front of the Royal Candles would this look right? Does Candytuft make a good border plant?  Should I just disperse one or two in my garden that has a bare spot and place the remainder plants elsewhere in my yard? Thanks in advance

So glad you've asked this, as a friend has given me some candytuft seedlings. Now all we need is someone who knows the answer!

Thanks for posting Green Magpie.  Yes, hopefully, someone will know the answer.  Candytuft doesn't stay in bloom long but when they do they are definitely worth the weight

If we're talking about Iberis, the perennial candytuft, then yes - it will certainly spread to 18 inches or more, given the right conditions.
It's very useful as an edging plant as it will drop over and down edging to cover it for an informal look.
Easy to propagate too. Little pieces put into gritty compost will take readily.

I’m growing some from seed this year too 😀

Thanks for replies.  I have decided to take a few out of the garden as 8 just seemed like a bit much  but I am going to try to find a place for the remaining 4 that I have. Hopefully, I can find a place. They are beautiful.
