I can't pick a favourite but right now I'm really liking Iceland Poppies. They're easy and re-seed just the right amount, and they look so bright and keep blooming a long time. Every colour looks like it would be a flavour of Sunny Delight. LOL.

I also like Penstemon 'Dwarf Navigator'. They don't reseed but they can be easily grown from seed and they are reliable with no bug or disease problems at all.

Well, I AM a little prejudiced so I have to say peonies. I do have many different cultivars. They are just so tough and so, so. beautiful! Of course I also have many daylilies and many irises too so the line is very close. :)

There is a 'Dropmore' cultivar of yellow foxglove that was bred by Frank Skinner. It has been coming back in the same place for several years now and so appears to be very hardy. The D, Grandiflora I had before that re-seeded in a different place each year and then died off completely. I have no idea if it is still available anywhere.

Oops! My last post was meant to go on the Foxglove thread.
I don't think I could say which is my favourite perennial. Chrysanthemums perhaps, particularly now with the Jefferies
hybrids which are hardy on the prairies. One perennial that I am very pleased with is 'Gentiana septemfida'. It has a long blooming time, is completely hardy and is very easy to grow but doesn't look like it.

Oh my! What a very difficult question.... so many wonderful perennials... hmm... the first one that came to my mind is tradescantia Blue and Gold. Have you seen that foliage!? OH MY GOODNESS! It is completely golden chartreuse, and forms an astonishing contrast with those deep blue flowers! Speaking about attention-seeking but with utterly good taste! :-)

I grew them in my zone 5 garden before. Now that I am in Calgary, I was completely overjoyed when I saw them for sale in a garden centre recently! Supposedly it's zone 3 hardy. I must get it when my backyard is finally ready for planting! :-)

Wow, that is a hard question! I guess i would have to go with lilies - a person can never have enough! Daylilies too. I also really like my lythrum - it has been so reliable and well-behaved over the years.

Iris's and peonies

Bleeding hearts and peonies(crimson ones)

Daylilies. Hardy, reliable, and so many different varieties. Ooh, clematis are nice too....

My favorite perennial is Rocky Mountain Penstemon, it's a true hummingbird magnet. Other than that I would have to go with iris, hostas or daylilies. I like the iris in spring, then the daylilies from summer into fall and when I need to rest my eyes on something that looks cool and relaxing, I head for the hostas. Oh, I almost forgot peonies! Marg

I really should stop reading this.......

I haven't finished planting everything you guys "made me buy" last year, LOL !!

NAF- you can't blame me I just got here a month ago "Whew!!"

Watch yourself.

These people like to make the newer members into plant addicts =:)

Clematis

waterlilies

Rhubarb ... okay, it's a perennial and gotta love rhubarb pie, lol

Hostas! But other favorites are iris, peonies, bleeding heart, lupines, roses, clematis... and the list could go on!

But don't forget crocus! Do crocus, being a spring flowering bulb, count as a perennial? I love them because they are early flowering, when we still have feet of snow in some parts of the yard! And the primroses too!

Thanks guys I do grow a lot of those mentioned and LOVE them all. I think that my favs change with the blooming times.
The spring brings tons of primulas for me white anenomes, virginia bluebells that I dug out of a ditch on a country road ( ? how they even got there no homestead anywhere)arabis creeping phlox called "firecracker" hot pink on long stems that blow in the windand the whispy forget-me- nots, need I go on.

Now the irises (siberian @ bearded ) are putting on a great show ,gerianiums"Anikins pride" "ballerina" splish-splash""splendora"etc. John coutts centerau,oriental poppies and on and on , The paeonies are almost ready to bloom along with the daylilies.Roses are all on their way too.
Sooo many childern!!!!! So CLBlakey watch out as NAF said the addiction goes on and on as well as one generation to another ( My father and Grandfather) Got to luv it Lois

Im in a zone 2b to 3 and its pretty rough here. We have lots of sage brush with white yarrow that I assume is indigenous. Ive started planting rose, lavendar and golden yarrow in the sagebrush. Its super hardy and will spread and looks so beautiful out in the sage. A much better show than the white.

it is a good thing I have other addictions (painting and decorating) to keep it in balance. I have been very good so far this year only bought 2 trees and some petunias. I have been giving away Jacobs ladder like crazy though.

Arrowwind- it is amazing what you can grow in 2b if you prep your soil we have clay here- I have bleeding hearts, peonies, columbine, irises (not sure what kind brought them with me from zone 5), jacobs ladder and my neighbour (the real gardener) has tons of other perennial flowers too.
