We are doing a big cross to introduce more genetic diversity and vigour to this variety. We hope to have seeds from this project available in December 2026.

9-Star Perennial Broccoli is an endangered sprouting variety that produces numerous medium cauliflowers year after year. Plants can live for several years if the cauliflowers are cut off before they open up and go to seed. Generally it produces one larger cauliflower head in spring, which you should harvest, and then several smaller heads will sprout up around the crown. It's called nine star because it will usually sprout about nine small heads. The leaves are also edible and tasty, like kale.

This variety is closer to wild brassicas, as it only starts making florets in its second year. There is variation in head size and how compact they are. Give it lots of nutrients for the most florets. After a few years the plants will get tired. You can try pruning them back heavily to reinvigorate them, or you may need to start a new crop eventually. Some folks recommend pruning the plants back every fall as well.

It may be possible to propagate these plants via cuttings, and avoid having to start them from seed again. After my plants flowered, they resprouted many shoots from the base, some of which I cut off and rotted directly in the ground, or in water. Time will tell if the cuttings survive the winter, but it seems promising.

PLEASE NOTE- There is chance some seeds may have crossed with Homesteader's Kaleidoscopic Perennial Kale Grex, and/or Candy Floss Kale. I isolated the plants with a pollination cage and used flies for pollination, but I did find a honey bee in the cage once so some crossing is possible. If you find any interesting individuals with colourful or other unique traits, please let me know, as it may be the start of an interesting new breeding project!

Growing Instructions

Sow in spring indoors or in a greenhouse a few weeks before last frost, and plant out when the chance of frost has passed. Space a few feet apart as the plants can get quite large. Put lots of rotted manure or compost in the planting hole, as these plants are heavy feeders. Side dress with more compost in subsequent years. Plants may require staking.
