I had good success with Shockwave. It stayed compact and had lots of bright yellow flowers.

How about Nearly Wild, The Fairy or Anne Boleyn (not quite constant but do repeat).

The Imposter? Fast repeat, likes heat, unusual color.

Here is a link that might be useful: The Imposter at HMF

A lot of the growundcover roses will be close to constant bloomers, although they grow quite wide. Constant bloom is a bit of a stretch really and open to interpretation as to exactly what that entails, but you'll find more options in pink than you will in yellow and purple, that somewhat fit that description. Usually, the roses that throw out smaller blooms are better at giving the impression of constant bloom than say the larger blooming roses which tend to flush and then repeat, but may throw a smattering of blooms here and there in between.

Letchworth Centenary is a very good mini-flora that stays small and is pretty much continuoulsy in bloom. The blooms are perfect little rosette's and very pretty.

The Fairy blooms late, but is usually always in bloom after that point.

Bubbles is a great groundcover that is pretty much always in bloom.

Sweet Chariot is a purple/mauve miniature rose and while not a constant bloomer, it throws out a huge flush in spring, repeats well and heavily and then another huge flush in fall.

Morden Sunrise, is the closest I have seen to a yellowish rose (the bloom colour is immensely variable) that is in constant bloom, but it will grow large in your zone without a lot of pruning and it can have BS issues in some climates.

Other yellowish roses that are not constant bloomers, but that repeat very quickly and don't grow very large mainly because of that fact, are Sunsprite, Julia Child and the Austin, Molineux.

Good luck.

You don't mention if you are looking for disease resistance.

Our Lady of Guadaloupe, Julia Child, White Pet, Princess of Wales.

A new one that has done well and bloomed lots for me is Incantation, Rogue Valley Roses. Have not had it long enough to really comment on it, but it blooms lots and one flush right after another.

Thanks everyone for all the suggestions!

Morden...do you have any photos of L.C. and Bubbles? HMF doesn't have any of either of them.

Masha.... the Imposter is sooo cute! It looks too sweet and happy to have that kind of name! Definitely a possibility.

A couple of you mentioned The Fairy and I have several already in a couple of spots near where these will be going. I DO love it though. It is pretty much always blooming. I have crystal fairy coming and can't wait to see how they do!

Alameda...i remember seeing incantation on rogue's website. It's a cutie too! hmmmm getting harder and harder to choose...

thanks again for some great suggestions and keep em coming!

Maybe Borderer would work for you? It is a polyantha, pink. I have two of these but planted them late last year so I don't know for sure, but the pics and recommendations were strong for this rose.

And Ashdown Roses has an ADR rose by Kordes called Pink Emely that looks like it might fit what you want; I ordered a couple of these and am anxious to see what they do.

How about The Fawn? It's a pretty pink and it reminds me of Austin roses. I got mine from Heirloom, own root, 2 years ago and I love it.

ohhhh they are all so pretty! I think The Fawn is gorgeous but it says occasional repeat and up to 7 ft. WIDE. Does your bloom alot and how wide does it get?
Thanks! April

April,

I do have pics of Letchworth Centenary and Bubbles, but I'd need to find them and they are not saved onto my Flickr account, so I can't post them here yet. If I get a chance, I'll look for them in my photo folders.

However, the Pickering Nurseries website has a picture of both roses and description.

Thanks MM...I'll check out pickering's site and check back here later to see if you found your photos. When I saw LC I was thinking I had seen it somewhere and maybe I saw on pickerings site a while back. Gonna go check them out!
April

ohhhhh I DO remember seeing LC now! How could I have forgotten??? I LOVE it. It just might be the one! Thanks so much for all the suggestions. Ya'll are a great bunch of rose friends.

The Fawn--I love it too. Mine is a three-year-old own root, also from Heirloom. It's kept under three feet and repeats heavily with charming pink blooms.

Carefree delight has done well for me.

Although J & P stopped carrying it, Royal Wedding is one of my most outstanding compact ever-bloomers. It's apricot blooms are gorgeous, and it is in bloom from late spring through late fall. Although it is a floribunda, its blooms have a hybrid tea form. Its foliage is dark green, glossy and quite disease resistant for me. Fragrant and a true workhorse - I can't imagine why J & P stopped carrying it. Roses Unlimited was carrying is on its own roots. I got my two from J & P (a gift from my sister).

April,

I found the pics of Letchworth Centenary and Bubbles so you can see what the blooms look like. On LC, they are about an inch to 1.5" across. On Bubbles, they are usually a good 2" across. Here you go.

Hi April, to answer your question about the Fawn, I have 3 together planted about 2 feet apart and they stay contained in an area about 8 feet long. They really put on a show and seem to be constantly blooming. This could be because they intertwine with each other. Let us know what you plant, Lori

These are very pretty. Already have Bubbles but think I am going to have to have Letchworth too. Pretty, pretty!

Thanks morden....those are both gorgeous! LC looks like the perfect color AND size. Bubbles is a cutie too! Thanks for taking the time to post the pictures. April

Pickering's 2009 catalog gives notice that this is the last year they will offer 'Bubbles'. Pickering is the only source in North America for this rose, so now is the time to get it if you're interested.

It a great little rose -- heavy bloom production and healthy foliage. Too bad it never gained much recognition on this side of the Atlantic.

Windeaux, I had overlooked Pickering's list in their online catalog of roses they will discontinue after this year, so thanks for 'heads-up'. There are 2 or 3 on the list that I may have to order -- which will mean that I'll have to wait until next year to get the 2 or 3 that I'll have to remove from my present list for '09. Decisions, decisions . . .

From the list of roses that Pickering is discontinuing this year, I highly, highly recommend the older Kordes semi-groundcover rose called Heidesommer. It is a beautiful, well-blooming, disease resistant rose with a wondeful sweet and pervasive scent that attracts tons of bees and hoverflies. I ordered two more this spring as I can't think of being without one... Unlike most groundcovers, it will stay no more than 2ft by 2-3ft here, at least.

I 2nd Our Lady of Guadaloupe.

The Meidiland rose line would fit your requirements. Pink Meidiland, Fushia Meidiland, Panda Meidiland. Also Bonica and Royal Bonica, Sevilliana.

Anyone have Gruss an Aachen? I was wondering about it as well. :-) Tons of great suggestions! Thanks for them all.
April

I love those pictures of Bubbles. But Pickering doesn't ship to the US, does it? And no one else has it. If anyone knows how to get one, could you advise?

Donna

Donna,

Pickering most certainly ships to the U.S. and Bubbles isn't one of the few roses that they cannot ship to the U.S.

April,

I have Gruss An Achen. Actually I have 3 of them that were originally located in different parts of the garden, but I moved them all into a triangle planting in my north bed. What would you like to know?

Hey morden...do they bloom well and often, what size do they mature at and disease resistancy? I have read good reviews on it and it seems to stay fairly compact from what i've read. I know you are in a totally different zone so that might make a difference. Thanks for any input.
April

Somebody already mentionned Shockwave. I bought 5 of them
last year and planted in a row in the entry to the house.
They were the mose cheerful plants in my garden. The yellow
flowers looked buautiful on the pretty roundy, compact
and greenish bushes. The flowers faded a little bit,
but in a way that they still looked beautiful and played
well with the new flowers. Once they shot a very long stem,
but I cut it off. It grew up to 2.5 feet.
