Dark Star, also known as Flame Nettle or Painted Nettle, is an ornamental member of the Mint family native to tropical Asia and northern Australia. This Coleus has a compact, upright habit of 12-24" tall and 20" wide. Dark Star's deep purple rounded, scalloped leaves are a low-maintenance summer annual for mixed containers or hanging baskets. This plant isn't cold-hardy but can overwinter indoors or grow as a houseplant. Dark Star flourishes in full or partial shade with minimal water, bringing hummingbirds to the tropical or modern landscape with its attractive texture and color.
Dark Star Selling Tips
Sell Dark Star to customers looking for unique foliage to add to a mixed container, landscape border, or houseplant collection. Customers will love the attractive contrast and texture Coleus's deep purple scalloped foliage offers. This plant is low-maintenance, requiring little more than regular water and full to partial shade to flourish until cold temperatures set in. While Coleus is evergreen in zone 10-11, it can overwinter indoors or grow as a houseplant in bright indirect light. This variety has a compact, upright habit, attracts hummingbirds, and resists deer. Create an inviting modern landscape border or mixed patio container by pairing this plant with Begonia, Calibrachoa, Fuchsia, Impatiens, Ipomoea, and Lantana. Plant alongside Jupiter for striking color contrast.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
