I grow clove currants and my family has grown clove currants since long before I was born. My mom had a single bush where I grew up in Kansas that produced berries. I’ve never seen a bush that doesn’t produce berries and literally have seen hundreds of them. Crandall is a regular clove currant believed to be improved. I’ve not seen a huge improvement from the wild ones but they are good bushes. There are small leaf bushes we call Missouri clove currant and larger hardier bushes we call yellow currants or Kansas currants. The ones my family grows of the Missouri clove currants produce less berries and is more ornamental which may be what they are calling a male plant. One strain our family grows might produce 50 berries total whereas mine produce in large clusters. The clove currants I grow berry color is variable. I have yellow berries, red berries, black berries with all different flavors. I assume the yellow berry variety is a true yellow clove currant. I like the crandalls which are a black berry much better when they are ripe. Gooseberries I think taste better but the taste is similar. The currents flavor are either loved or hated there is no in between. Most people spit them out when they eat them but one out of 10 says what are these I love them! I love the flavor. This is what the wonderful smelling flowers look like Clove currants - great smelling blooms & delicious fruit!
