“SLO Red Plum emerged as a fortunate accident when Doug Bullock discovered a naturally occurring seedling of Thundercloud plum in San Luis Obispo, California. Thundercloud had long been cherished as a strictly ornamental plum, valued solely for its dramatic red foliage and springtime blooms. This unexpected seedling inherited the parent's stunning appearance but diverged in a crucial way: it began producing an annual crop of small, tasty fruit that Thundercloud never bore. The discovery transformed an ornamental-only tree into a productive specimen, expanding its appeal beyond landscapers to gardeners seeking both beauty and edible yields.”
