Red Rubine Brussels sprouts (Brassica oleraea gemmifera ‘Rubine’) are unique, colorful plants that produce an abundant harvest of striking, reddish-purple sprouts. The plants are tall, reaching heights of 3.25 feet (1 m.) at maturity. There are many good reasons to plant Red Rubine Brussels sprouts. The plants aren’t difficult to grow, they’re beautiful in the garden, and cooks appreciate the gourmet sprouts for their rich, nutty flavor.

Rubine Brussels Sprout History

Botanists think Brussels sprouts were first grown in Medieval Europe, specifically the area currently known as Belgium. However, Brussels sprouts weren’t introduced to North America until the mid-nineteenth century.

The beautiful color of Red Rubine Brussels sprouts was created by crossing Brussels sprouts with red cabbage. The plant dates to about 1954, so although it is relatively new, its age qualifies as an heirloom plant. However, true heirloom plants are open pollinated and never hybridized.

Growing Heirloom Brussels Sprouts

Growing Red Rubine Brussels sprouts is no different than growing any other type of Brussels sprouts. However, this particular type of Brussels sprouts takes a little longer to ripen than traditional green varieties, and the yield may be smaller. For this reason, Red Rubine is often grown for its ornamental value.

Like all Brussels sprouts, Red Rubine is a cool weather plant that requires fertile, well-drained soil, regular fertilizer and consistent moisture. Locate Brussels sprouts where the plants receive at least six hours of sunlight per day, preferably more.

Pick Red Rubine Brussels sprouts when they’re firm and measuring about an inch (2.5 cm.) in diameter. Pick from the bottom of the plant so the small sprouts at the top will continue to mature.
