Black Amber Plum: July's Black Pearl from My Garden

Walking through the garden in mid-July, I looked under the branches — plums hanging heavy, turned almost black. It was time to harvest the Black Amber.

I was amazed when I first encountered this plum. From the outside it looks deep purple — almost black. But cut it open and the color changes instantly: bright yellow, juicy, sweet flesh. This contrast between skin and flesh is what sets Black Amber apart from other plums.

What is Black Amber?

Black Amber is a Japanese plum variety (Prunus salicina) developed in California in the 1980s. Its large fruit, thin skin and long shelf life made it quickly popular among both gardeners and small-scale producers.

The exterior is almost black — deep purple-black skin. Inside: bright yellow, honey-scented, incredibly juicy. The sweetness-acidity balance is perfect. Wonderful eaten fresh, and ideal for jam and preserves too.

Black Amber in Our Garden

Our tree performed beautifully this year. The branches were struggling to hold the weight of the fruit — a sign of an exceptionally productive season. Organic mulch, minimal pruning and drip irrigation. The soil and sun did the rest.

No chemical spraying. Black Amber is quite resistant to pests — especially its disease tolerance is much higher than European plums.

How to Know When to Harvest

The color deepens fully and the fruit softens slightly when pressed. The stem separates easily. Don't wait too long — at peak ripeness it can start to crack. We harvested in mid-July, perfectly timed.

How to Use It

Best eaten fresh — biting into it and having that yellow juice run is an experience in itself. For excess: freeze, make plum jam, or turn into vinegar. We converted some of this year's harvest into plum vinegar — the color and aroma were magnificent.

Its Place in a Permaculture Garden

Black Amber is an ideal fruit tree for a permaculture garden. Spring blossoms provide nectar for bees. Fallen leaves become organic matter for soil. Fruit to the table, scraps to compost. A complete cycle.

If you have a Black Amber in your garden, treasure it. If not — plant one as soon as you can. Seeing those black pearls hanging from the branches when July comes is a pleasure in itself.
