Here’s why I ask- this is what MSU has to say about it. Ariel –
Tree has moderate vigor and upright but open growth habit. It is very precocious, it in the third leaf. It is productive. Fruit is oblong to round. Base color is yellow-orange with a very nice red blush covering most of the fruit
surface. It is covered with moderate waxy bloom. Flesh is amber-yellow, very firm, juicy, sweet with a touch of tartness making it very palatable and enjoyable. It has very high brix in access of 23%. Ripens late in the last week of
September - first week of October. This is one of the best plums that seem to have everything to seduce the consumer: eye-appeal, size, firmness and great taste.
Gotta get some wood.
