\ud83c\udf45 Quick take:<\/strong> Purpur Isonica<\/strong> (likely a phonetic variation of Purpur Isenika<\/em>) is an indeterminate<\/strong> dark purple plum heirloom distributed by Bulgarian master collector Hristo Hristov<\/strong>. Yielding juicy 2-5 oz (60-150 g) oval-to-beaked plums, it is hailed as a bulletproof “garden workhorse” for cold-climate open ground. It sets fruit continuously through weather shifts and remarkably maintains its sweet, balanced flavor even when harvested green and counter-ripened indoors. \u00a0Full summary \u2193<\/a><\/div>\n

Mid-season indeterminate variety. Fruits are juicy, weighing 2-5 oz (60-150 g), deep dark pink-to-purple plums, setting both with and without a distinct pointed tip.Grew this outdoors in open ground. Completely fuss-free and rugged, heavy yielding, and set every single cluster without dropping a blossom: an absolute workhorse of a variety.<\/p>\n

Outdoor Hardiness, Counter-Ripening, and Scented Flavor<\/h4>\n

Flavor is remarkably balanced with plenty of sweetness. Seeds came out of Bulgaria from collector Hristo Hristov.<\/p>\n

What really stood out is that the fruits hold onto their rich flavor even when picked green and counter-ripened indoors off the vine. Cross-section photo below is from an indoor-ripened tomato:<\/p>\n

Grew this variety again for a second consecutive year. The fruits were sweet and delicious all season long, and the vine grew completely outdoors in the open garden bed.\"Purpur<\/a>
