This almost-black beauty is equally at home in formal and cottage gardens. Scabiosa blooms for an exceptionally long time, is fairly drought tolerant, and is very attractive to bees and butterflies. Long stems are great for fresh cut flowers. Dried seed heads also add interest to flower arrangements. A top-notch garden cultivar since the 1600s when it was known as 'Blackmoor's Beauty' or 'Mournful Widow'.

I saw this plant at Denver Botanic Gardens and was so excited to see you had it in the catalog. It came up beautifully and is just as imagined.

I'm not sure if anyone else had this experience, but last fall I sowed all the seed from one packet of these (2018 seed) and they've just bloomed and are ALL WHITE. No color at all in them. They're lovely, just the opposite of what I was expecting...

Didn't work out

Again no flowers yet
Patricia C Tompkins from AZ
Owner Response: Thank you for taking the time to share your experience with this cultivar. Like many perennials, these do take some time to flower and starting them indoors can be really helpful in speeding up flowering. An abundance of nitrogen can also result in lush plants with little to no flowers. Please feel free to contact our horticulturists with questions at any time, horticulturist@botanicalinterests.com.

long lasting dark beauty

Started seed indoors, put transplants outside. Very long blooming period as mentioned. I staked my plants and they had a dozen heads that bloomed in a row. So pretty and a great contrasting flower against my pink garden phlox and peach four o'clocks.

Sweet flowers, low germ rate

2 out of 5 stars May 17, 2020
I grew these to use as cut flowers and for dye plants. The germination rate was very low and I had to do multiple successive sowings.
Aimee Miklovic from MT
Owner Response: Hello Aimee, Thank you for taking the time to write a review. We are sorry you experienced a low germination rate with the scabiosa seeds. Our seeds are tested frequently by a third-party laboratory to ensure germination rates exceed federal standards and our own. A customer service agent will be with you soon to help with the issue.

Not so good

Very poor germination. The few that did died before they were 4". Disappointing

Black knight scabiosa

5 out of 5 stars Jan 1, 2021
Only started 4 so far indoors using my biodome. 100% germinated within a week. All now have 4 sets of true leaves in just under 3 weeks. I will be uppotting them soon and continue to grow indoors until spring. Can't wait to see them flower! I stumbled upon this website accidentally and am impressed with the germination rates so far thank you Botanical Interests!

12 seeds

Excited to start these today, especially after reading the reviews. However I think my packet had 12 not 25 seeds or maybe there are more seeds within each of these pods?
Debra from CO
Owner Response: Dear Debra, Thank you for notifying us of this issue. We apologize you received a packet that was short seed and we would like to make this right. A customer service agent will be contacting you shortly about a replacement packet.

So. Many. Blooms.

This is the first year I've grown Scabiosa, and they have quickly become a new favorite for using in flower arrangements. They do need some support to stay upright, but the color is such a deep, rich burgundy, garden pests don't seem to bother them, and the plants keep churning out bloom after bloom. Long, strong, foliage-free stems make them perfect bouquet flowers.

Black Knight Scabiosa Pincushion Flower Seeds

5 out of 5 stars Sep 21, 2021
This was my first year growing the Black Knight Pincushion flower from seed. Almost every seed germinated however with the colder & rainy spring here, most of my seedlings that I transplanted into pots fell victim to "damping off". Fortunately, I hesitated to pull them and gave them a chance and eventually the bees (and I) were rewarded with the most beautiful flowers! Hopefully next year's Spring will be more cooperative.. :)
Amy from NY
Owner Response: Hi Amy, Sprinkling cinnamon around seedlings stifles fungus, like dampening off, in case that is helpful.

Very pretty flowers, healthy plants. I've been dropping the seed heads in the garden all season for more plants in 2022.

Butterfly magnet

This scabiosa was winter sown, then transplanted into a big terra cotta pot on my patio. Prime growth was mid-summer, and it attracted Skipper butterflies.

Rich deep, dark red

4 out of 5 stars Dec 6, 2021
I started some seeds indoors and some by winter sowing. Better germination with winter sowing. Once planted in the garden they grew well and produced beautiful deep, deep red flowers over several months. Good cutting flower too, with long vase life.

Easy to grow and are stunning when they bloom. I live in PA and started them. I showed them outside the first week of May. We had an unusually wet and cold Spring this year. They started to bloom in Mid July are beautiful. It was my first time growing them. I wish I could add a picture to the review.
Ginsag from PA

Black Knight Scabiosa is Fantastic !!!

5 out of 5 stars Aug 13, 2022
What a phenomenal plant; gorgeous dark blooms add extraordinary contrast among light roses. Seed was direct sown, grows tall and narrow. From now on I will always try to have this outstanding beauty in my garden.
