Solanum muricatum - Pepino Dulce. A South American native, s. muricatum is grown for its sweet, edible fruits. UNFORTUNATELY the pepinos don't travel well so may be hard to track down in the UK. FORTUNATELY you can grow your own in a greenhouse/sunny conservatory, the taste is said to resemble a mix of honeydew melon and cucumber.
Golden Midget Watermelon - 70 days. A beautiful miniature watermelon that weighs around 3 lbs. It's easy to tell when they are ripe, as the rind turns a lovely golden yellow when ready for harvest, a very beautiful contrast with the salmon-pink colored flesh. The taste is sweet and refreshing. Very early, matures in just 70 days. Developed by the late Dr. Elwyn Meader, UNH in 1959. Unique.
I would LOVE this in my backyard!!! I grew up on a farm that had a fruit orchard (mainly apples) and seeing an apple tree like this with big juicy red apples on it, has always brought about much excitement for me. Love it!
