Redblush Grapefruit Budwood

Citrus paradisi.

Said to have originated as a limb sport of Thompson that was found in 1929 by A.E. Henninger of McAllen, Texas, and patented by him in 1934. This is the first citrus variety to receive a patent.

Fruit similar to Thompson in all respects except for much deeper pigmentation in the flesh (but not in the juice), crimson blush on the rind, especially at points of contact between fruit; albedo pigmented.  Holds on tree as well as Marsh or Thompson but with some fading of flesh color.  Similar to Thompson in season of maturity.

Tree indistinguishable from Thompson or Marsh.

Because of the attractive appearance provided by the pigmentation of the rind and its deeper flesh coloration, Redblush (Ruby) rapidly superseded Thompson and some years ago became by far the leading pigmented variety and one of the major grapefruit varieties.

Carrizo citrange, C-35 citrange are good rootstocks of accession. Season of ripeness is February to June in California.
