Lime green continues to be one of the hottest colors in the garden, and a coleus called Wasabi provides it like few others.
The Electric Lime variety has always been my favorite coleus, but I find myself pinching out flowers daily. But Wasabi, with its showy serrated leaves, has not had its first bloom.
While lime green or chartreuse is a color that shouts "look at me," it also somehow makes all other colors look stunning. Foliage plants like Wasabi also can serve as a transition color, tying the garden together when you might otherwise have a clash of colors. It is like a mediator between rivals, bringing tranquility to the garden.
I am not the only one raving about Wasabi. In trial grounds, it has garnered a perfect score since the last week in May. As it was getting established in early May, it was scoring better than 3 out of 5. Since then: perfect 5 out of 5.
Never miss a local story.
Wasabi, propagated by Ball Horticultural Co., is suggested to reach 30 inches in height and 28 inches wide. That might be achievable in the North, but it grows like it's on steroids in the South, where it can be allowed to grow larger. It offers you the possibility of growing an incredible lime green hedge.
Wasabi is easy-to-grow, low-maintenance and almost foolproof when grown in well-drained soil and watered through droughty periods. Since coleus is grown for its boldly colored foliage, the fact that Wasabi has had no blooms will make every gardener and landscape professional ecstatic. This trait makes it a perfect partner for another coleus from the Ball company, Redhead. A combination of Redhead, with its large dark red leaves, and the lime green Wasabi just might be all you need to win Yard of the Month in your neighborhood.
Our careful bed preparation, with loose well-draining organic matter, allowed us to come through record precipitation. If you have tight, heavy clay, then work on improving your soil condition too. Ideally, at least one-third of the final soil mix should be some type of organic material.
To accomplish this, spread 2 to 4 inches of organic matter and about 2 pounds of fertilizer per 100 square feet. My favorite fertilizer for coleus is a 12-6-6. Till this in, and you'll be ready to plant. This pre-plant fertilizer followed by light monthly applications will keep the plants growing well until frost.
Wasabi coleus is perfect for planting in the tropical-style garden. We have ours winding like a thread of gold or chartreuse among plantings of SunPatiens, bananas, small palms, King Tut papyrus and night-blooming jasmine. I've seen terrific combinations with scaevola and pentas as well. You will easily come up with partnerships to fit your style.
There are still a lot of warm weeks left over much of the country. A planting of Wasabi coleus would look right at home until frost. Or you can wait until spring. Just know Wasabi is the finest lime green coleus on the market.
