Olive Tree (Ascolana)

Description Ascolana is a classic Italian table olive grown for size, texture, and curing quality. The fruit is notably large and meaty, with a high flesh-to-pit ratio that makes it especially well suited to home curing, brining, and fresh preparation. Originating in central Italy near Ascoli Piceno, Ascolana—often referred to as Ascolana Tenera—is closely tied to traditional Italian olive culture. It’s the cultivar behind the famous olive ascolane, prized for fruit that holds its shape and texture through curing and cooking while maintaining a relatively gentle bitterness. Ascolana’s growth habit is more traditional and less compact than modern high-density olives, but size and vigor are still strongly shaped by climate and care. In warm, in-ground plantings, trees can grow with moderate strength over time, while container-grown trees or those managed in cooler regions tend to remain more restrained. With pruning and thoughtful siting, Ascolana can be successfully grown in home gardens where table olives are the goal. Overview Italian table olive cultivar prized for very large fruit High flesh-to-pit ratio ideal for curing and stuffing Milder bitterness compared to many olive varieties Mid to late-season ripening olive Pollination required for reliable fruit set Growing Details Latin Name: Olea europaea ’Ascolana Tenera’Origin: Marche region, Italy (Ascoli Piceno)Site and Soil: Full sun preferred; well-drained soil is essentialCold Tolerance: UC Freeze Category: Moderate; established trees have reported wood survival around ~15°FRootstock: Own-root (propagated from cuttings)Bearing Age: Often fruits once established; production improves with maturitySize at Maturity: Typically maintained at 8–12 ft tall and wide with pruningNote: Size reflects managed garden or container-grown trees; growth and ultimate size vary by climate and whether planted in-ground or in containers. Unpruned trees can grow larger over timeBloom Time: Mid to late spring (varies by region)Ripening Time: Mid-season olive; harvest timing varies by climate and season lengthPollination: Pollination required; plant a compatible olive variety within 20–30 feetPests & Diseases: Generally resilient with good airflow and drainage; regional pressure varies Additional Notes Grower’s Insight: Ascolana’s standout trait is fruit size. It’s grown specifically for table use, not oil, and excels when cured as a green olive or used in traditional preparations. Regional Insight: Performs best when planted for warmth, drainage, and sun exposure; suitable for home growers focused on table olives rather than oil production. Cold-weather note: In olives, the primary cold risk is bark splitting during sudden freezes rather than slow, sustained cold. Proper siting and drainage greatly reduce risk. Harvest note: As a table olive, fruit is typically harvested green and cured rather than allowed to fully blacken. Explore more olives in our collection: Olive Trees
