They all do well here. I love em because they bloom for such a long time. The taller ones, called Sweet Williams are wonderful and will come back from seeds each spring. The shorter ones will also return from the roots and will spread to form a beautiful mat. They bloom naturally in Spring but will also continue to bloom intermittently throughout the summer. Dontcha just LOVE dianthus!!!?

Sweet Williams are a biennial though.

You might like the perennial dianthus. I got mine at Lowes mark down table. Plant them in full sun, they are drought tolerant, and have a much longer blooming season. I got the Amazon Neon Purple, they also have pink ones. I love this new plant. Barbra

I bought the Amazons as well, Barbra, and I really do like them. They are still blooming.

I was at Lowes Saturday, but couldn't find names on any of the dianthus.
I have about six or seven different types of seeds, but Amazon isn't one of them.
I'll watch for that one.

Ruth, I will check to see if mine have seed........if so, I will harvest some for you.

I didn't use to like them until someone gave me a 6-pack. I planted them in full sun and they lived and lived and lived. Through super cold winters and super hot summers. They just kept living and blooming all year 'round. Can't go wrong with these flowers.

Mine are just starting to set blooms, I love that the stems are purple instead of green. Mine are just starting to send up blooms. They are much taller than the regular dianthus, and really like to spread. I can't wait to go down this weekend and see if they are blooming yet. Barbra

Our Dianthus needs trimming. I'm wondering if it can be cut back really low. Any help would be appreciated.

I have had very good luck with Melody Pink and First Love Dianthus. Both of these grow to about 15-18" in height, which I much prefer to the shorter varieties. I've never grown these from seed, but have had good luck finding young plants at local garden nurseries.

jardineratx, First Love is what I started from seeds last year. They have been blooming for a while now and I love them. I bought the seeds at Summer Hill seeds, but this year they don't have them. I'll have to look for Melody Pink. I did start several different kinds from seed this year.

I just looked at Summer Hill seeds and they do have First Love. They must have been out when I placed my last order.
Most of the ones I sowed this year are annuals, but no blooms yet.

I plant them in the fall, and they generally will bloom throughout the winter unless it freezes. And they will continue to bloom until it gets really hot, then they die out. I've never had any survive the summers down here!
