Summary from transcript: In North Carolina, a second-year Thomasville graft produced green to almost-ripe fruit. The grower described green fruit as lime-like for cooking; at yellow it had a slightly sweet edible peel and tart juice; and overripe orange fruit became soft and bland. In the green sampled fruit, the grower reported few seeds, very juicy pulp, orange-like aroma, sour/tart but not overly sour taste, and no detected trifoliate bitterness. These are grower impressions by ripeness stage, not universal maturity dates or hardiness guidance.

Summary from transcript: After a snowy night reported at −4/−5°C, the grower said most small orange Thomasville fruit froze, while larger fruit near a wall remained firm. The grower described some leaf and new-growth damage but considered the tree fine. This is a site-specific report; it does not establish a cultivar hardiness limit.

Summary from transcript: The grower showed Thomasville scions grafted on trifoliate orange that were less than one year old and already flowering or budding, and said the young grafts would not be allowed to carry fruit yet. This supports early flowering of these grafted scions, not seedling bearing age or a completed first-year harvest.

Summary from transcript: The Thomasville fruit in this comparison had been refrigerated through winter and was not presented as freshly picked fully ripe fruit. The grower reported no visible seeds in the cut specimen, a lime-like taste, and tougher skin than Augusta citrangequat. In the grower’s zone 8 setting, Thomasville was said to be useful green around Thanksgiving but not fully ripen without protection; the caption wording at 6:06 conflicts with the immediately following green-use statement. The grower also considered Thomasville the least seedy and versatile for cooking and drinks among the three sampled citrangequats. These are source-specific observations.

Summary from transcript: In an exposed Greene County, Georgia orchard, the grower showed an own-root Thomasville seedling from an old Savannah tree. He described it as initially lanky, then rounded with age, estimated it at about 15 feet, and reported repeated flowering with rain cycles, productive crops, and marmalade use. He said its fruit could retain through winter when lows remained around 20°F or the low 20s. This is a grower report, not an instrument-controlled freeze threshold.

Summary from transcript: The grower framed small Thomasville plant and rootstock trials as site-specific experiments. He described maturity and use as conditional by stage and protection, reported one very small standard-trifoliate-rootstock plant surviving a 10°F low with leaf burn and twig dieback, and observed different early growth and fruit holding among rootstock combinations. These are local, unreplicated observations, not cultivar specifications or controlled hardiness trials.

Summary from transcript: A direct tasting used yellow-to-orange, partly green greenhouse fruit from small Flying Dragon-rootstock plants. The presenter described aromatic sweet zest, difficult peeling, few seeds, orange and kumquat-like flavor, tart pulp, and no detected bitterness or trifoliate influence; he discussed fresh, marmalade, candied-peel and juice uses. Four fruit averaged about 42 g, and the captioned reading was 9 °Brix with pH 2.7 from combined juice. This is one greenhouse/rootstock-specific tasting. The matching scorecard summarizes this same tasting, not an independent sample.

Summary from transcript: In the grower’s setting, Thomasville plants were described as relatively dwarf and slow-growing but repeatedly flowering and carrying many fruit. The grower called yellow-to-orange fruit excellent and green-stage fruit lime- and orange-flavored. This short personal report has no measured fruit size, hardiness test, or annual-flowering measurement.

Summary from transcript: The presenter and a second taster tried one very ripe orange Thomasville fruit. The presenter recalled earlier green and yellow fruit as bitter or sour; the second taster called the current whole fruit delicious. The suggestion that further hanging until March could improve it was speculative. Captions end shortly before the stated runtime.

Summary from transcript: On Valentine’s Day 2025, the grower described winter-hanging Thomasville fruit after substantial but not extreme cold. He considered remaining fruit ornamental rather than clearly edible, said fruit could persist to spring or summer unless frozen, and reported loss of most fruit after a low around 20°F or below. This is a site-specific winter-fruit account, not controlled freezing evidence.

Summary from transcript: The grower described greenhouse protection allowing Thomasville fruit to ripen beyond the green stage. He and his wife found current-color fruit palatable with sour-kumquat and navel-orange flavor, preferred fruit from yellow onward, and said orange fruit could dry out if left hanging too long. This is a personal greenhouse harvest preference without a defined sample or maturity standard.

Summary from transcript: A backyard potted-tree grower described green fruit as lime-like, yellow fruit as lemon–lime-like, and orange fruit as orange-like. In a ripe-fruit tasting, she called it very juicy, orange-like, a little tart, and sweeter than Meyer lemon. These are one presenter’s unmeasured observations by maturity stage.

Summary from transcript: In coastal southern North Carolina, a grower described productive Thomasville plants and green fruit as exceptionally juicy, lime- and orange-flavored, useful as a lime substitute, and usually with one or two seeds. A second taster preferred an in-between green/yellow fruit as lime-like and more useful than orange fruit. The source includes unsupported history, hardiness and disease assertions, excluded from this citation; ripeness impressions conflict with other source accounts.

Summary from transcript: In Greene County, Georgia, a grower showed an own-root seedling from an old Savannah tree, estimated at 8–9 feet after about five years. He reported local blooms/crops in April, early June and July, late-November/early-December coloring, lime-like fruit before color, and fruit that may persist into summer if not frozen. This is a specific seedling and location, not a cultivar-wide growth or maturity specification.

Summary from transcript: In a late-summer tasting of green Thomasville fruit, the presenter described lime-like appearance and aroma, a couple of seeds that were more than usual for the grower, good acidity, and a clean flavor without perceived trifoliate off-flavor. The presenter said the fruit was not fully lime-like and, at this early stage, had not developed its sugars; a spoken reading was 7 °Brix. The presenter used the fruit in sweetened limeade. These are source-specific impressions of an early green sample, distinct from the ripe greenhouse fruit in the separate Thomasville scorecard/video record.

USDA Citrus ID reproduces Swingle and Reece’s account of the 1909 citrangequat breeding program: Swingle used Willits and Rusk citrange pollen on safeguarded oval and round kumquat flowers. Thomasville, Sinton and Telfair are named among the resulting cultivars; the generic passage does not by itself identify each individual parent pair.

Summary from transcript: The grower tasted a late-held, overripe Thomasville sample with mostly depleted flesh. He said Thomasville is ordinarily juicy around December, can be used green as a lime before frost, and in this late sample tasted kumquat-like, slightly bitter but acceptable; he suggested marmalade. This is not a fresh or ideal-fruit sample and does not establish universal fruit quality.

Summary from transcript: The grower reported that Hershell Boyd at Madison Citrus Nursery grafted Thomasville on about May 15 and, roughly six weeks later, one graft was already blooming and setting fruit. This is an attributed nursery observation of grafted-scion precocity, not mature harvest or seedling bearing age.

The publisher’s Thomasville scorecard summarizes the same yellow-orange greenhouse tasting as bAVid6H5ZLc: rounded mean weight 42 g, 9 °Brix, pH 2.7, sweet/sour fruit without reported bitterness, very juicy flesh, difficult peeling and orange/kumquat flavor. Original trait ratings are quality scores, not the catalog’s intensity categories. The card and video count as one sample; printed hardiness bands are guidance rather than a freeze measurement.

Summary from transcript: Tom McClendon describes his seed-grown Thomasville tree, about 20–25 years old, with many flower buds. He reports spider-mite problems on this tree under a cypress and an oak, while another of his Thomasville trees in the open did not seem to have the same problem. The comparison is specimen-specific; he offers the nearby trees as a possible explanation, not a demonstrated cause.

Summary from user-provided translated excerpt: The supplied attachment attributes a Feb. 3, 2024 post to jibro and says it reproduces an AI DeepL translation of a Tiny Mandragore nursery listing. The excerpt reports Thomasville tolerance to −12°C and speculates it may tolerate more severe cold; separately it says fruit is damaged from −4°C and recommends protection from cold winds. These are translated, second-hand nursery claims about its plant, not an independently verified trial or a measurement by the forum poster. The full thread and original nursery text were not independently retrieved. The excerpt supplies no exact site, event date, exposure duration, temperature instrument, tree age, rootstock, or quantified recovery method; preserve the stated cold-wind qualification.

In post #353753, Ilya11 reports repeated Thomasville flowering in the author's climate, seed set after cross-pollination by other hybrids during spring bloom, and usually seedless fruit after early-July bloom when no other citrus is flowering. The author says Thomasville seed produces only nucellar seedlings, that cross-pollination is needed to induce seed, and that flowers carry some fertile pollen especially in hot weather; the author also reports producing several dozen hybrids with 5 Star Citrumelo. These are grower observations and claims; the post gives no locality, sample counts, pollination protocol, or genetic test confirming nucellarity or offspring parentage.
