The winter here in southeastern Pennsylvania has been relatively mild, but we’re still a long way from the lushness of summer, so it’s a good time to be looking at pretty pictures. Here’s a sampling of some of my favorite blue and purple-blue flowers and combinations.
First, a few portraits:

And to finish, ‘Jolly Bee’ geranium with ‘Souvenir d’Andre Chaudron’ catmint (Nepeta sibirica), ‘Icicle’ spike speedwell (Veronica spicata), and ‘Becky’ Shasta daisy (Leucanthemum x superbum).
So many different shades of blue and all so lovely! Caryopteris ‘Snow Fairy’ caught my eye too with that delicate varigation. I really liked ‘Dark Reiter’ as well…very smokey and mysterious appearing. I am going to have to google some of the plants you show here as I am not familiar enough with them to know if they are annuals or perennials, the anagallis for instance. Thanks for reminding us that summer is only a few months away and that it really WILL come! I always feel a bit desparate this time of year.
Hey, Kate – sorry I didn’t think to mention whether the plants are annual or perennial; that would have been useful to readers. I’m glad you enjoyed it anyway!

Is that Monkshood at the top of the page?
Yep, that’s Aconitum carmichaelii. By the way, if you put your cursor over any image, you should be able to see complete ID information.

Nan, This is a post after my own heart! I adore all the beautiful photos and plant combinations. Do you allow Pinterest? I would love to add some of these to my design board to help me with my garden when it comes time to face the nurseries and catalogs and I get all giddy with plant lust. Thanks for all your great posts.
Hi Laurie! Yes, Pinterest is ok, as long as you link to the images here. I’ve noticed a few people copying photos to their own blog or photo archives and linking to those, and that’s not cool. Thanks so much for asking!
-Nan
It is “that” time of year Nan when we crave these beautiful colors and forms. It won’t be long now.
Spring certainly has been early here, Lisa. I don’t remember doing so much weeding in any other February.
-Nan
Nan! I love love love those blues! Has anyone else noticed that the English call many purple flowers blue? It’s not just my imagination, is it? We actually have different colors -colours;) – in our minds when we say “blue flower” – you can tell when looking at British websites or seed catalogs… For all English speakers the blue poppy *IS* blue, as is Commelina coelestis and blue pimpernel – nobody could call them violet or anything else – but a lot of what I, as an American, would call mauve or light purple or violet or somethig else the English call “blue” – and when they are here in the garden and see some purples they sometimes say “What beautiful blue flowers you have! I now know to just smile, and not ask “Where? – what blue flowers? Those are purple!”
You have a good point, Clark. I think it’s partly an issue of comparison, for me, at least. When I see the irises I’ve shown here, for instance, I think “blue,” until I see the Commelina or the Anagallis and realize the difference. Putting these all together really made the differences apparent.
-Nan
Dark purple has always been my favorite color in the garden. And although garden writers like to call them “blue”, ask any grade school kid what color it is, and they will say “purple”. Granted,you actually have some true blue flowers (like the anchusa and salvia). True blue flowers are quite rare in the garden, and a special treat.
Your photos are lovely, as always. You show so many combinations I would think you must have 10 acres under cultivation. Any idea how many different plants you grow?
I just love the larkspur and baby’s breath combination, those little dots of white contrast sharply with the deep purple, and yet highlight the white eye of the larkspur. Does your larkspur reseed for you or do you start it from seed every year.
That commelina looks so similar to spiderwort, and a true blue.
Love your garden!
That’s why I included “and purple-blue” in the lead-in, Brenda: If I’d only included the “true” blues, it would have been a very short post! I don’t think it’s just garden writers who call some purples “blue,” as noted in Clark’s comment below; I notice that even non-gardening visitors do that.
No idea how many different plants I have, or how many have come and gone in the last 10+ years. The larkspur does self-sow now, from a mix of colors I scattered a few years ago. I keep trying to get rid of the washy pink ones and seem to be having some success.

Good morning Nan, love the post. I have tried to grow caryopteris here, it does extremely well the year planted, blooms gorgeously but doesn’t survive my cold March/April,snow melted and wind I guess. I have even seen buds on it but it doesn’t make it. Do you grow that ageratum from seed? I can’t find it in Canada. A few of the seeds you sent me are up, the cotton looks like blackish radish! and the streaked platycodon are up too, only about 1/8 “. I love to garden in the winter!
Do you know Jodi Delong? She had a great talk yesterday about winter interest at the local Nursery. I told her you sent me seeds and I am going to donate some of the plants to her plant sale for the schorlship fund in honour of Capt Steele, our local Rhodo hero.
Hi Susan. I have had mixed results with Caryopteris x clandonensis, but C. incana has been pretty reliable most years, to the point of the yellow-leaved kinds self-sowing. The ageratum self-sows too. The cotton seedlings *do* look like radish seedlings, don’t they? They’ll darken as they grow. And yes, I’ve been reading Jodi’s blog for years. Thanks for supporting her plant sale!

Hi Nan!
It never ceases to amaze me the depth and variety of plants you have in your garden! Gorgeous photos and combinations.Thanks for sharing.
Barbara
Hey you! Thanks for stopping by. I’m already making a list for our spring plant shopping.
-Nan
As always, so wonderful to be treated to these beautiful purple-blue flowers in your beautiful and unique way of presenting them. Thank you for sharing them with us. Here’s to a great new season of gardening.
Wonderful to hear from you, Dorothy. In a way, it’s almost like the gardening season never ended this winter, with it being so mild. I never had witch hazel blooming in January before.
-Nan
Your pretty blue/yellow combos have inspired me. Last year I painted the shutters on my house blue and the front door a golden yellow. I have blue flowers but need more yellow. Thanks for the ideas.
That sounds lovely, Melanie. I’m very partial to yellow flowers myself, and fortunately, there are lots to choose from.
-Nan
Sorry, I didn´t like the blue with the pink – it became too “sweet”. But the other combinations were lovely!
I don’t recall making any of the pink-and-blue combinations on purpose, but I kind of liked them. I too prefer the other combos, though.
-Nan
Be still my heart! I always look forward to your posts, but this one is delicious eye candy. Some of my favorites I grow and a few to look for! Stop in and visit my site too when you get a moment.
Thanks, Brooke. I’ll be sure to visit soon. Right now, the garden beckons!
-Nan
Well, I am in awe of your beautiful mixture of flowers…..so well-planned! I have copied so many plant names from your pictures that I must begin to save for them now in order to purchase when Ohio weather becomes warm again…….if I can find them in local nurseries. Thank you for this little “trip” into Spring on a cold Sunday morning.
I appreciate the comment, Sharon, though you give me too much credit for planning these pairings; most were just happy accidents. If you have trouble finding any of the plants, don’t hesitate to ask: I may be able to tell you where I got them, or their seeds, at least.
-Nan
So many beautiful blues in your gardens. I adore it like most gardeners I expect. The Dark Reiter geranium is just gorgeous and I will have to add that to the never ending list. LOL! Thank you for all of these lovelies for today.
I think it’s the yellow-leaved lemon balm behind the ‘Dark Reiter’ that really shows it off so beautifully. I imagine it would be nice with silver companions too.
-Nan
Thank you for the lovely February walk through the garden Nan. Viewing your pictures was a welcome respite on this cold and gloomy day.
I’m glad to have brightened your day a bit, Debra!
-Nan
We are in high summer here and I can’t help but compare your photos of lush, weedless swathes of colour and foliage to my own weedy nightmarish borders! We have had an astounding amount of rain for this time of year and the garden is growing like mad – I can’t keep up!
That Dark Reiter geranium is gorgeous. And I’ve never seen/heard of the variegated comfry. Love it! Especially alongside the yellow stripy variegated iris. Do you grow the comfry from seed?
Hey, Kerry. Remember, you’re looking mostly at closeups; one can hide a lot of weeds by shooting from the right angle.
Sadly, no, ‘Axminster Gold’ doesn’t come true from seed; it must be propagated by division or stem cuttings.
-Nan
So many wonderful plants!! I especially loved the larkspur/sea holly combo! So dramatic!!
I’m sorry to report that the sea holly didn’t make it past that year, but it sure was nice while it lasted – thanks to the dark background, especially.
-Nan
Your BLUES are AMAZING! Love them!
I hope you liked the purples too!
-Nan
Nan,
As always, your photos are amazing and the pairings are just beautiful. I just love the lavender, wooly thyme, feather grass and hydrangea with the bunny. The composition is so soft it seems to invite you in to nap right there on the wooly thyme. It’s almost cloud like. I love to see Hayefield in my inbox! Thank You.
How nice, Sandi – thank *you*! The bunny does enjoy his little thyme lawn.
-Nan
I stopped by your blog for a dose of inspiration and motivation for both gardening and blogging. I’ve been on a hiatus while writing a fiction novel that was so much fun (and now I must gather my courage to try to find an agent…that part feels too much like work).
Blue/purple with yellow/gold always works for me! Your garden vignettes are glorious.
Good for you, Freda – that’s a terrific accomplishment! What a great way to spend the winter. I hope you have good luck finding an agent.
-Nan
Well, I guess blue does go with everything. Such wonderful combinations beautifully captured.
Thanks so much, Carolyn!
-Nan
One could never have the blues after looking at these.
Heh – apparently I don’t have the blues either, Layanee.
-Nan
I was feeling a little blue this morning since I’m learning to live with some health issues. — until I read your post. Your beautiful creations and photography are inspiring. I’ll go out to the garden today and make a plan to add some blues to my garden.. (I am fortunate to have friends who volunteer to do the things I can no longer do in my garden.) Thank you for another gorgeous and informative post.
Good to hear from you, Marie. I’m so glad that you have friends to help you keep your garden going. I wish you a great growing season!
-Nan
It’s probably no secret that I absolutely adore blue and purple in the garden…I really can’t get enough of either! I really need to remember to try to find ‘Dark Reiter’, that rich, saturated color is just amazing…especially paired with the lemon balm behind it…really sets it off just perfectly. I really love that South African Foxglove paired with the Agastache…the similar spiky forms, but different (yet complimentary) colors are just wonderful. Your photo of the ‘Limerock Passion’ Coreopsis makes me want to try them…I seem to remember when they first came out, people had trouble with them lasting more than a season…but I think that’s been remedied, to a degree…and that color is stupendous!
Hey, Scott! None of the ‘Limerock’ coreopsis are hardy for me, but the colors are so terrific that I have no problem using them as annuals.
-Nan
Wonderful photos, Nan, as always. How does that Sarastro campanula do for you? I’ve considered it many times, but Kansas heat and humidity generally don’t suit bellflowers. Mighty tempting though.
Thanks, Tom! I’m actually pretty impressed with ‘Sarastro’: it’s lasted here 4 or 5 years now (about 4 times longer than most campanulas), in a site with pretty heavy soil, though it’s also right next to a gravel path. I imagine your summers are even hotter than ours, but our PA summers can be very humid, so maybe you’d want to give this one a try.
-Nan
Such wonderful combinations. There are several I would like to try. I even have several of the plants but they just aren’t together.
Well, we’re heading into a great time for transplanting, so maybe some plant-moving is in order? Have fun!
