PLANT CHARACTER
Perennial, twining legume supplied by Chemiseed Sdn. Bhd. (Malaysia). Stems become woody with age. Rooting in nodes when in contact with moist soil.

Growth: Spreads via stolons under favorable conditions.

USES
Green manure, nitrogen fixation, weed suppression and erosion control under tree crops. Calopogonium caeruleum is one of the most shade-tolerant tropical legumes, staying productive across 60 to 100% light transmission and persisting under mature canopy where other covers thin out. In a Nigerian trial it gave the second-highest green-manure effect among 12 legumes tested, an equivalent of about 90 kg N/ha (Tropical Forages, CSIRO/CIAT). For optimal germination, pair with Seed Activator.

GROWTH HABIT
Tolerates heavy shade. Grows in soils with pH as low as 4.0. More drought tolerant but slower to establish than CM and PJ. May take 20 months to achieve a complete cover. Compare species performance in our cover crop comparison guide.

No Shirt Pocket!
Fit Type: Regular Fit, Color: Blue Stripe, Size: X-Large
No Pocket! The material was nice quality, a little thicker than I would have anticipate for a low priced shirt, and very soft. The only disappointment was there was not shirt pocket. I suppose I did not look closely enough at the photos to notice that before I purchased. Otherwise, this is a very comfortable shirt.

Bought in multiple colors! Fantastic material
Size: X-Large, Color: Light Green, Size: X-Large, Color: Light Green
I ordered this button-up for an upcoming beach vacation, and I’m honestly so impressed with the quality and feel of it. Right out of the package, the material felt soft, breathable, and exactly what you want when you know you’ll be spending long hours in the sun and heat. It’s incredibly lightweight without feeling cheap or flimsy, which was one of my biggest concerns when ordering. What I really love is how well it helps keep you cool. The fabric allows for great airflow, so you don’t feel like you’re overheating or sweating through it like you might with heavier shirts. Even just trying it on, I could tell it’s going to be perfect for hot, humid weather. The fit is also spot-on—not too tight, not too baggy—giving it a clean, relaxed look that works great for both casual outings and slightly nicer dinners by the beach. Overall, this shirt checks all the boxes: comfortable, breathable, stylish, and ideal for vacation wear. Already grabbing a few more colors

Slim but comfortable sizing looks upscale, wrinkle free from the dryer
Size: Medium, Color: Denim Blue
This is a very nice upscale looking shirt. It has great styling that is not over-sized. My husband normally wears a medium or large depending on the cut/style. He got a medium in this size and it is a perfect, comfortable fit. It arrived with some creases in the material from being folded in the packaging but it came out beautifully from the dryer. I'm happy he has a casual but nice shirt to wear when he takes me out to dinner!

A true vacation find!
Size: Medium, Color: Light Green
Really nice choice. Got it for my husband and he really liked the style. I loved how it fit on him and the lightness of the fabric. Great for hot, sunny weathered days, or warm nights. A true vacation find. Both comfy and stylish. He would have preferred it be 100% cotton, but I think he didn't really mind after steaming it. He commented on the color too. A beautiful sage green!
