Spooky season is almost here, so let’s talk about some of my favorite ingredients for dark, moody arrangements.
These are 11 I actually grow and use in my design work, plus why they’ve earned a spot in my garden:
**Hollyhill Black Beauty Dahlia**
About as close to black as I can get in a dahlia. Deep burgundy, great size for designing, and doesn’t overwhelm an arrangement.
**Chocolate Cosmos**
Small, dark blooms on thin, wiry stems that add beautiful movement. And yes, they really do smell like chocolate!
**Black Knight Scabiosa**
I LOVE the wonky stems that bend and curve through an arrangement. Plus, the flowers and seed heads are both usable.
**Diablo Ninebark**
A workhorse foliage shrub. Beautiful flowers in spring, textural seed cases afterward, and deep burgundy foliage I can cut throughout the season.
**Jessie G Dahlia**
Beautiful ball form, excellent vase life and SO striking in person.
**Rubenza Cosmos**
Opens deep ruby red and fades as it ages, giving me multiple tones from the same plant.
**Queen Lime Red Zinnia**
The mix of burgundy, dusty rose and lime makes this one of my favorite “bridge” flowers for tying a color palette together.
**Shadow Cat Dahlia**
Super dark, vigorous and gives me long, strong stems that are great for designing.
All three dahlias were sourced through Connell’s Dahlias
**Amaranthus: Red Spike + Love Lies Bleeding**
Two completely different design jobs: Red Spike gives me strong vertical lines, while Love Lies Bleeding adds dramatic drape and movement.
**Purple Red Strawflower**
A long harvest window, great texture and one I can dry to keep using long after the growing season ends.
**Aromatto Basil**
Foliage and dark purple flower spikes on the same branching stem. The more I harvest, the more it branches and produces.
You don’t need an entire garden of nearly-black flowers to create a moody arrangement. I love growing a mix of focal flowers, smaller blooms, foliage, spikes and trailing ingredients to give me different shapes and textures to work with.
