I planted my main garden this past weekend, a full week ahead of schedule. Here is a picture of some of the Tokita Sundee series showing plant sizes. All seeds were planted on the same date, and consistent with Barb’s findings, the Sunorange F1 (“improved Sungold”) is already well ahead of the standard Sungold F1. Other Sundees shown to the left are also much bigger. All of the plants shown except the Sungold F1 have flowers which should open soon, with Sunorange F1 and Sunpeach F1 being the most developed. I had doubles of Sungreen F1, Sunchocola F1 & Sunpeach F1 which were slightly bigger than those shown here, but had been planted in another garden last weekend.
Not shown are Tokita varieties SunLemon F1, Suncherry Extra Sweet F1 FT, Suncherry RB F1 FT and Goldencherry F1 since they took so long to germinate.
Germination:
Sungold F1 - 3 days (Halifax Seeds) 100% germ.
Sungreen F1 - 4 days (Osborne Seeds & Seeds n' Such) 100% germ.
Sunpeach F1 - 4 days (Seeds n' Such) 100% germ.
Sunorange F1 - 5 days (Osborne Seeds) 100% germ.
Sunchocola F1 - 7 days (Harris Seeds) 100% germ.
Suncherry RB F1 FT - 10 days (Seeds n' Such) 75% germ.
Suncherry Extra Sweet F1 FT - 18 days (Seeds n' Such) 75% germ.
Sunlemon F1 - 22 days (unknown) 20% germ.
Goldencherry F1 23 days (Vesey's Seeds) 100% germ.
