2025/2026 Dahlia Breeding Season Results
Hello friends,
Today I thought I'd share with you the results of the 2025/2026 dahlia breeding season.
I grew a total of 55 dahlias from seed, or as seedlings, and at the end of season only 14 dahlia seedlings remain. The number of dahlias I've kept is unusually high, and this is a result of me growing some of Floret's Petite dahlia seedlings, which I bought from Emerden last spring. They were unusually populated with promising dahlia seedlings, and this in my opinion makes buying these expensive Floret seedlings completely worth it.
To keep a track of all my seedling dahlias during the season I employed a dual system, first of all a dahlia seedling spreadsheet, and also a physical note book with a page per seedling, noting down when it flowered, what type of dahlia it was, colouring, and photos showing each dahlia in flower.
The majority of dahlia seedlings that flowered were single dahlia types, and most of those dahlias were the colour yellow. This makes sense because the single dahlia type, and the colour yellow, are both dominant in dahlia genetics according to the book "Dahlia Breeding for the Farmer-Florist and the Home Gardener". Thirty eight of the fifty five dahlia seedlings were single types, equaling a total of 69% single dahlias in my breeding experiment. Twenty seven of the fifty five dahlia seedlings had yellow flowers, or they had yellow colouring in their flowers. Both single type dahlias, and dahlias with yellow flowers, are not what I'm looking for in a dahlia in general, as they are very common, and not really interesting to me.
This dahlia seedling, SR5, is a typical yellow single dahlia flower. I don't consider it interesting at all, even though the bees love these flowers. I don't have enough space in my small garden to justify growing them every year.
And now for all the amazing dahlia seedlings I grew this last summer.
First up we have Keith Hammett Beeline II #4, a dahlia seedling from a Beeline II seed packet I bought from the dahlia breeder Dr Keith Hammett. Dr Keith Hammett doesn't have the space to grow every single seed in his breeding program, so he sells seeds packets occasionally. This dahlia is a single dahlia, but the pink to yellow ombre colour shift is just spectacular against its dark green leaves. This dahlia, KHBII #4, is very similar to Dr Keith Hammett's Mystic Sparkler dahlia, which I own and love in my garden. However, this flower is much larger, and I prefer this seedling dahlia's petal shape more, so it makes it worth keeping this dahlia for next year to see how it fares.
Next up is another Dr Keith Hammett dahlia seedling, NZ Gardener #1, which is grown from a seed packet given away by the NZ Gardener magazine. This is a yellow decorative dahlia, with great symmetry in its petals. Even though this is a yellow dahlia, I haven't seen many pure lemon decorative dahlias for sale in New Zealand, and this is the only decorative dahlia seedling I grew this year. It's worth growing for another year to see how it looks over time.
This next dahlia seedling is called Floret Bee's Choice #13 (FBC#13), AKA Pink Lemonade. This is a yellow, white, and pink anemone dahlia, with unusual domed inner anemone petals. I really love its delicate colours, and it's unusual anemone shape. This dahlia is quite pretty, and has a lot of potential. I'll be growing it for the next couple of years, to see how it develops as the tuber gets older.
The next dahlia is another Floret Bee's Choice seedling #15 (FBC#15). This is another anemone dahlia variety, and it is two toned, with pale lemon outer petals, and brighter yellow inner domed petals. I've called this one Daffodil Daze, as it reminds me of the fluffy double daffodil flowers I grow in my garden each spring.
This next seedling, SR#4, is another anemone dahlia. I'm not really sure what to think of it, but I love the purple colouring. I'm willing to grow it in my garden for another year to see if it improves.
This white collarette dahlia seedling is SR #13, which I've named Snow Dancer (named for the Snow Dancer wolf pack in Nalini Singh's Psy-Changeling book series). She's such a pretty white collarette dahlia, and since I have none growing in my garden, she will make a happy addition to my dahlia collection.
The following dahlia seedling is Floret Petite #2, a magenta on magenta collarette dahlia. This is a really pretty dahlia I bought as a seedling from Emerden Garden last spring. She reminds me a lot of the Cafe Au Lait Rose dahlia, and she also has a large flower head for a collarette dahlia. She's definitely a keeper for next year, and I've collected seed from her to see what dahlia types I get from her.
This next dahlia seedling is Floret Petite #3, which is another anemone dahlia with great potential. New flowers are a very pretty smoky peach colour, and she fades to a apricot colour as the flowers age. FP#3 is definitely another keeper, and I can't wait to see how she performs next summer.
Next up is Floret Petite #4 a stunning lemon and magenta streaked collarette dahlia with white frilly petals inside. She is a stunner in the garden, and very much appreciated by those noticing her. This dahlia probably has the most potential of all the dahlia seedlings I've grown this year. I can't wait to see her flowering again next summer. I haven't chosen a name for her yet...
Floret Petite #5 is another collarette seedling dahlia, and has pointed lemon petals, and curly white inner petals. She was growing in a bad spot in the garden, and didn't get a lot of sun, so I don't think she's grown to her full potential this year. I'm going to grow her in a better place next year, and see how she fares.
And next is Floret Petite #6, my favorite of all the dahlia seedlings I grew this past year. She is a very unusual anemone dahlia, with the outer petals colour shifting in an ombre pattern from dark to light pink, and the inner anemone petals doing the same, but with gold tips. What is also interesting is her 3D shape which is very pronounced, making her look like she's wearing a poodle skirt. She is just stunning and looks nothing like any other dahlia I've ever seen. Her colouring shifts as the flowers age.
I have also kept dahlia seedling Floret Petite #8 until next year. Unfortunately Floret Petite #6 grew beside FP#8 and completely overshadowed the dahlia seedling. Because of this, the dahlia seedling stayed quite small, and it also didn't flower this year. Due to the prevalence of great Floret Petite dahlia seedlings, my plan is to grow it for another season, to see if it has potential.
And finally we have two unknown dahlia seedlings, Unknown 2 and Unknown 4, which popped up in the back garden over summer. Their parent plant I think is Dahlia Protegee, which grows nearby them, and I think when you see the comparison photos you'll agree with me.
First up is the suspected parent plant, Dahlia Protegee, which is a Keith Hammett bred dahlia. She is an ombré magenta to salmon pink single dahlia with dark leaves. This dahlia is an absolute bee magnet all summer long.
And this is Unknown #2 dahlia seedling. She has green leaves, her petals are rounded, and her petal colouring is a deep pink ombré fading out to a baby pink outer. There are also dark pink streaks throughout her petals. When this dahlia flower ages, the light pink fades to a white shade which is really pretty.
And this is Unknown 4 dahlia seedling. She has fewer petals, green leaves, but has more of a pure pink ombré effect. There are also streaks of darker pink running through the leaves. She is also very pretty.
As you can see from these photos, they do indeed look like dahlia Protogee's daughters. I'm happy to keep these dahlias for another growing season to see how they look and change over the growing season.
Overall my dahlia breeding season was very successful. At the start of the season my hope was to grow 2 - 3 dahlia seedlings which were promising enough to keep for another season, but having 14 is a bonus. All I have to do now is store them successfully over winter, and then grow them again next spring to see how they fare. In the mean time we've already had 4 frosts, and my dahlias have all died back, and winter is fast approaching...
Have a wonderful day

Some of My Favorite Dahlias This Summer Season
Hello friends,
Today I wanted to share with you some of my favorite old and new dahlias for the 2024/2025 summer season that I didn't get a chance to do a dahlia profile on, because life is always crazy busy in the garden over the summer.
First up is Strawberries and Cream, a decorative dahlia I bought on a whim after a couple of dahlia tubers died last spring, and I needed to replace my Cafe Au Lait dahlia. The shades of white and pink are just so pretty and girly, and the flowers have nice long stems, which make them perfect for cutting.
Next we have one of my favorite old dahlias, Protegee, which is a pretty single dahlia bred by Dr Keith Hammett. This dahlia is a bumblebee magnet all summer long, and really stands out in the garden.
Next we have another old favorite, Penhill Dark Monarch, which is a huge dinner plate dahlia with just wonderful shades of purples, pinks, and apricots.
Next we have another new decorative dahlia, Iced Tea, which I've really fallen in love with over this summer. I am quite happily keeping this dahlia for next year, and can't wait to see it with lots of bright peach flowers.
Next up we have one of my first new anemone dahlias, The Phantom. It's pop of bright purple flowers is a great sight to see in the garden over the summer. Unfortunately I planted it in the wrong place, so I'll move it to a better position in winter.
Fenna Baij is another new anemone dahlia, with very pretty light purple and gold shades.
Pink magic is a floriferous waterlily dahlia which brightens the garden all summer. I've really fallen in love with waterlily dahlias this summer, so I think I'll invest in more next season.
I replaced my Cafe Au Lait dahlia this season, after the old dahlia tuber rotted last spring in October. I replaced it, and this dahlia has the purple-tinged shades my previous dahlia didn't have. I'm very happy about this, and will be moving this dahlia to a better position over the winter.
Next we have Silver Years, which is a mostly white decorative dahlia with pink vein striping, and a cream center. I really like this dahlia as a pop of white in the garden, and am quite happy to keep it for next year.
Dutch Pearl is another new waterlily dahlia, and it really is stunning next to my Little Miss Perfect rose. I can see why this dahlia is very popular in dahlia circles right now.
Next there is my new Cafe Au Lait Royal dahlia, another dinner plate dahlia to add to the Cafe Au Lait dahlia family. The light pink colours and striping are just stunning. I need to find a better way to stake the plant though, the flower heads are huge, and the dahlia has some trouble holding them up.
And finally we have another new dahlia, Pinky Swear, which is another large dinner plate dahlia, and the striped pink shades, along with yellow are just florescent. I'm very happy to have this dahlia in a darker part of my garden.
I'm just so pleased to have so many beautiful old and new dahlias flowering this summer, and hope to have some more new ones next season...
Have a wonderful day

Dahlia Profile - Keith Hammett Beeline II Flowers
Hello friends,
Today's dahlia profile is for the dahlias grown from Keith Hammett's Beeline II dahila seed mix.
From his website: "This series is different as it is based on 'Dark Destiny', a cultivar resulting from a cross between a dwarf hybrid garden dahlia and Dahlia sherffii, a species not previously used in Dahlia breeding...The colours are more restrained and much of their beauty lies in light being transmitted through the ray florets (petals) to give a stained glass window effect. Compact self supporting plants with finely divided foliage."
I sowed 6 seeds, and all of them grew big enough to plant out in the garden, and they all flowered.
Dahlia 1:
Dahlia 2:
Dahlia 3:
Dahlia 4:
Dahlia 5:
Dahlia 6:
As you may have noticed, Dahlia 6 really is the star out of all dahlias grown from Keith Hammett's Beeline II seed mix. The inner part of the ray florets are a deep tangerine which changes ombré style into dark pinks/purples. There is also streaks of dark pink coming out from the inside of the floret all the way to the outside. It definitely has a stained glass effect, and it really stands out in the garden.
Out of all the Beeline II dahlias I grew, only dahlia 6 stands out well enough for me to want to keep the tuber in the coming years. Dahlias 2, 3, 4, and 5 are all pretty plain looking, and don't interest me. Dahlia 1 is kind of tempting, but we'll see how it performs over the rest of the summer and autumn to gauge if it will be worth keeping it.
Have a wonderful day

Spring Seed Sowing Week 1
Hello friends,
We're now into the last month of winter, and it's finally time to start sowing seed for spring. It's a tricky time of the year, as it's possible to get snow here in Dunedin even into the first week of October, so there's nothing worse than sowing seeds too early, and then having to try and keep them alive if there's a late frost or snow in early October. Last year we had snow laying on the ground the first week of October, and a couple of frosts the weeks after that, so it was a stressful time trying to keep all my seedlings alive, looking after my growing potato plants, as well as my new dahlias which had just popped out of the ground. Seedlings don't get transferred outside and into the vegetable garden until Labour Weekend, which is the third weekend of October, so that's a long way off right now.
I have a specific order in which to germinate seeds, so that I don't have too many plants sitting in the glasshouse for such a long period of time. The first seeds sown are my tomato plants. I grow enough plants for our own needs, but also for family members as well. I usually have at least 12 plants growing in our glasshouse, and poke any others that are spare in free space I have in the vegetable garden. We eat a lot of tomatoes fresh throughout the summer, but the bulk of it is frozen away for using in autumn and winter cooking.
This year I'm growing the following tomato varieties:
Franchi Sementi Pomodoro Red Cherry - A red cocktail tomato with great taste. This is no longer for sale in New Zealand, I save this seed every year.
Kings Honeybee F1 - I haven't tried this one before, I wanted to try another cocktail tomato, we'll see how this goes. One of my sister's grows her tomatoes outside, and it's far easier to ripen smaller tomatoes in Dunedin's short summers.
Kings Tomato Juane Flamme - Our favorite tomato, an orange tomato with the best taste of any tomato I've ever grown.
Tomato Grosse Lisse - A beefsteak tomato that was a favorite of my grandfather. The best tomato for putting a slice on a hot piece of toast, and eating it with a pinch of salt on top.
Tomato Island Bay Italian - I haven't grown this tomato variety before, but I've heard good things about it. Good for eating fresh and processing apparently.
Tomato Lebanese - Also a new tomato variety this year, I'm hoping it will have good disease resistance, and tastes good too.
The next seeds to be germinated are my chilli and capsicums plants. I've successfully grown chillies in our greenhouse, but I haven't had any luck with the big traditional bell pepper capsicums.
This year I'll be growing the following chillies and peppers:
Chilli Serrano - I had a huge crop of chilli last season, so I'm growing this variety again.
Alma Paprika Pepper - Trying once again to grow my own paprika. Last season they didn't grow as well as I hoped, am trying again for the last time.
Capsicum Marconi Red - A prolific sweet Italian variety. I'm hoping that it's narrow shape will mean it ripens faster.
Capsicum Orange Sun - My last attempt at growing a bell pepper variety.
Capsicum Red Bell F1 - Also another last attempt at successfully growing a bell pepper variety.
The tomato and chilli seeds were sown into two mini greenhouses, and placed in a warm sunny spot in our dining room. It's warm in there on sunny days, and also thanks to the benefit of our wood burner being in that room, they're kept warm in there every night in winter. I'm eagerly waiting for the seeds to germinate.
The next seeds to be sown are all my sweet pea varieties. I've collected quite a lot of Keith Hammett varieties over the years, he's a New Zealand breeder who produces the most stunning sweet peas. Sweet peas germinate in cool temperatures, so they are now potted up and put into the glasshouse.
The last of the seeds to be sown for now are the herbs coriander and dill. Coriander prefers to grow in cool temperatures, otherwise they will bolt, so I sow one lot in late winter, and another in early autumn. They don't like to have their roots disturbed while planting into the ground, so I sow a bunch of seeds into a biggish pot, and then when it's time to transfer them into the herb garden, I plant the whole container worth in one spot, I don't separate out the seedlings at all. For the dill seeds I do the same thing as with the coriander, it ensures I get a relatively big crop of leaves without the problem of using up a lot space.
The sweet peas, coriander, and dill are all now sitting in my glasshouse. We're were expecting snow down to 200 m last night, so I've put off doing any more seed sowing tomorrow. Hopefully soon they will be joined by a lot more seeds as the month goes on.
Have you started seed sowing yet? I'm interested in what choices you've made for the coming growing season.
Have a wonderful day
Julie-Ann
