Gulf Ruby Plum
Prunus salicina 'Gulf Ruby'
“150 hours. Dark red skin, red flesh. The Gulf Series workhorse.”
Gulf Ruby is the most popular of the Gulf Series for a reason — 150 chill hours, dark red skin, red flesh, good size, excellent flavor with a balance of sweet and acid. Cross-pollinates with Gulf Gold, effectively doubling your harvest when planted together. Ripens slightly earlier than Gulf Gold. Heavy producer once established. The kind of plum that makes people stop complaining about grocery store fruit. Zone 8–10.
