Redblush Grapefruit

Hodgson (1967) describes Webb Redblush as a limb sport of Thompson observed by J. B. Webb of Donna, Texas, in 1931, propagated soon afterward and introduced in 1934. The account reports separate discoveries for Ruby and Redblush while treating them as practically indistinguishable in cultivation.^⁠[2]⁠[4]

UCR describes Redblush as low-seeded, with pink flesh, a crimson rind blush, and pigmented albedo; the flesh color may fade while fruit remains on the tree. IDtools describes fruit as broad as long or longer than broad, with yellow-to-orange rind and orange-to-red or purplish flesh. Nursery descriptions add sweet, juicy fruit (GDNC also calls it tangy; Seville Oranges calls it fragrant), while GDNC says heat is needed for good ripening and gives late-winter-to-early-summer timing for Coachella Valley. These are general descriptions, not measured fruit samples.^{⁠[1]⁠[4]⁠[3]⁠[5]}
