AAS (All-America Selections) Winners

AAS (All-America Selections) Winners

We carry dozens of All-America Selections winners, including seven Johnny's-bred varieties -- Jasper Cherry Tomato; Baby Bear Pumpkin; Bright Lights Swiss Chard; Diva Cucumber; Sunshine Kabocha Squash; Bonbon Buttercup Squash; and Carmen Pepper. Read about Johnny's Plant Breeding Program (article by Rob Johnston Jr., Johnny's founder and chairman).

All-America Selections is an independent, nonprofit organization that trials new varieties alongside two or three similar varieties currently on the market, then introduces only the best garden performers as AAS Winners. Submitted vegetable and flower varieties are tested by a geographically divergent network of independent judges to determine whether their garden performance is truly superior, with winners chosen on the basis of scores received from judges at 34 sites in the U.S. and Canada. Johnny's is proud to be an official trial ground site for AAS. (To learn more, visit the All-America Selections website.)

Shipping Information & Notes

Growing Information


CULTURE: Cauliflower prefers a well-drained, fertile soil high in organic matter, a pH of 6.0–7.5 with a consistent supply of moisture throughout the growing season. Irrigate regularly for best results. Cauliflower does not do well in hot weather; the best success is with spring and fall crops.
Use early and midseason varieties. Sow in 72-cell plug flats. Seedlings should be ready to transplant in 4–6 weeks. If possible, keep soil at least 70°F (21°C) until germination, and 60°F (16°C) thereafter. Transplant outdoors when seedlings are no older than 4–5 weeks old. Older plants tend to be stressed and do not perform as well as actively growing seedlings. Harden plants carefully by gradually increasing cold before transplanting out, 18" between plants and 24–36" between rows.
Use midseason and storage varieties. Start seedlings as above in May and transplant to the garden in June–July. To ensure mature heads, seed the crop early in areas where heavy freezes occur early in fall.
WINTER CROP: Successful cauliflower crops can be grown where winters are mild (temperatures rarely below 32°F (0°C)). Transplants can be set out from September to February in these regions.
DIRECT SEEDING: Sow 3–4 seeds 18" apart, ½" deep, rows 24–36" apart, thinning to one plant in each group.
DISEASES: Adhere strictly to a preventive program including: (1) long crop rotations with non-cruciferous crops, (2) clean starting mixes and outdoor seedbeds, and (3) strict sanitation practices. Black rot can be seed-borne. We only stock seed lots that have been tested free of black rot in a sample of 30,000 seeds.
NOTE: A disease-free test result means that in the sample tested, the pathogen targeted was not found. It does not guarantee a seed lot to be disease-free. However, no method of seed treatment can positively insure freedom from disease. We are glad to help with specific questions.
INSECT PESTS: Repel flea beetles and root maggots on young seedlings by covering with floating row covers from day of planting. Treat flea beetles with pyrethrin or azadirachtin if heavy pressure is observed. For cabbage worms and loopers, use Bacillus thuringiensis (Bt.). Cutworm prevention: Cultivate soil 2–4 weeks before planting to work in cover crops and destroy weeds.
BLANCHING: When small white heads become visible through leaves, gather the outer leaves over the head and tie with string or a large rubber band to preserve white curd color. Although tying is not necessary to grow cauliflower, the practice helps prevent yellowing of the curd due to exposure to sunlight and results in better head quality when curd develops during hot weather.
Keep an eye on development, cutting heads when desired size is obtained but before the curds becomes loose, or "ricey."
Store at 32°F (0°C) and 95–98% relative humidity for 2–3 weeks.
SIZED SEEDS: Standard except where noted.
SEEDS/LB.: 81,350–178,900 (Avg. 110,200).
100 seeds unless otherwise noted.
