Summary from transcript: Tough Citrus tastes a Ten Degree Tangerine that is ripe in November, describing a sweet-tart, lemonade-like flavor with more acidity than a typical sweet mandarin. The fruit has yellow skin with some green areas, orange flesh, a fragrant mandarin-and-lemon rind, and soft, very juicy flesh. Its loose peel comes away easily, and the presenter reports roughly one or two seeds per segment. He favors it for backyard growing and suspects its softness would make shipping difficult. He discusses the Clem-Yuzu selections, identifies Stan McKenzie as the supplier, relays a report of survival at 8°F, and suggests growing it in Zone 8 areas such as the Carolinas.

Summary from transcript: The Mulberries compares Ten Degree Tangerine with Owari Satsuma, examining the peel, flesh, seeds, aroma, and taste. The Ten Degree sample weighs 110 g and measures 10.5 °Brix; its pH is estimated at 3.1 using a color comparison. It has yellow peel, light-orange flesh, very easy zipper peeling, moderate seediness, and fairly juicy flesh that drips less than Satsuma. The flavor is moderately sweet and sour, with mandarin and lemon notes and no detected flesh bitterness. The rind combines mandarin, yuzu, lemon, and floral aromas; the zest has a slight bitter edge. The presenter enjoys it fresh, discusses kitchen uses, compares tree shape and productivity, and relays cold-hardiness claims and possible growing conditions.

Printed pages 8–9, “Clement tangelo” (PDF pages 22 and 25). Page 9 records the introduction of Clementine to the United States in 1909 through budwood sent by L. Trabut in Algeria, and notes plantings in southern Texas. This provides historical context for the inferred Algerian Clementine parent; it does not identify the particular tree or clone used in Brown’s later cross.

Summary from transcript: The Mulberries tours Ichang papeda, Yuzu and related hybrids in Central North Carolina, Zone 8a. The grower compares vigor, foliage, winter damage and recovery, and discusses selecting seedlings for hardiness and fruit potential. Yuzu produces off-types across seed batches; Ten Degree Tangerine produces a small proportion of visibly different seedlings, including presumed trifoliate hybrids; Ichang Lemon also produces zygotic seedlings at a low, unquantified rate. Recent Yuzu × trifoliate and Ichang Lemon × Thomasville pollinations have set fruit, with hybrid offspring still anticipated. Reported seedling variation is based on grower observations rather than genetic testing.

Native transcript retained extract, 1:14–1:45. The presenter calls Ten Degree Tangerine “Clem Yuzu 2-2,” says “Clementine × Yuzu,” describes easy peeling and a lemonade-like taste, and reports a specific tree survived 8°F in 2018 but took damage. These are speaker/nursery assertions. No new parentage record is implied; the clip gives no rootstock, exposure duration, protection, or measured tasting data.

Summary from transcript: Ten Degree Tangerine survived but vigorous top growth was burnt/pitted, and an earlier tree required replacement after heavy damage (36:00–37:24).

Summary from transcript: Algerian fruit from a mature flood-irrigated Arizona tree peels one-handed at 1:41–2:19. This citation is a visual reference for an editorial comparison with Ten Degree Tangerine; the video does not discuss Ten Degree or establish parentage. The uploader description mentions puffing after maturity, but caption timing is ambiguous and no puffing-timing claim is imported.

Relevant contributor: theMulberries, post 13 (August 23, 2026). The post gives a qualitative fruit description but does not identify a specimen, harvest, location, rootstock, or sample count; it is not an independent or measured tasting trial. Post 6 discusses propagation for the collection generally and does not identify Ten Degree's propagation or rootstock.
