When you think of a new plant or flower for your garden I bet you never thought about black flowers? But, guess what… they exist! And despite their contradiction to a vibrant colorful flower, black flowers can offer charm and really pull you deep into the gardening world! Here’s a little bit about some of my all-time favorites. We’ll start with the “Black Magic” Petunias.
I first stumbled upon the “Black Magic” Petunia at ACE Hardware. I’ve grown many petunias over the years in my private garden, but admittedly I’ve never seen anything as wickedly sweet as this! Unique in color and perfect in size as to not overwhelm your garden, this Petunia is less eerie and more mythical in nature. To me, it reminds me of a velvet cloak. Every time I’m in Los Angeles I swing by my friend Kat Von D’s home and contribute meaningful flowers for her Black Garden and this go round was one of her most favourite additions.

Obsessed? Addicted? Me, too! But there’s more – the black sunflower brings a sort of mystery to a “colourless” garden and can mesmerise your eyes and make you feel like you’re being pulled into a limitless mind space of possibility.

A simple search on Instagram under #blackflowers and you may also come across this irresistible double black hellebore, or one of the edible flowers, the ‘Molly Sanderson’ Viola and then there’s the super rare Copiapoa tenuissima which resembles (no big deal) the entire Milky Way.

All of these may be available at your local garden center. For me it’s all about the thrill of the hunt and I like to start local. But, if you’re pressed for time online is an option. Try visiting; Annie’s Annuals, Burpee Seeds and Baker Creek Seeds.

- Hoya pubicalyx Black Dragon – @kebint
True, these plants are easy to grow, but do be sure to take note of the care instructions. A good green rule of thumb I live by is using a quality planting mix and be sure to fertilise often, for best show. Lastly, don’t forget about deadheading your flowering beauties.
