These pictures were taken early in the season.
Heat Tolerance: This tomato likes heat but a string of days in the 90's can cause blossom drop. This stress can take a week or more to recover from, delaying and reducing harvest. Woven shade cloth supported above the plants by poles is used by some growers to moderate temperature.
Fruit: Very small like cherry tomatoes, red, slighly oval, bunches don't ripen simultaneously
Germination rate: 100%
Time to Germination:
Seed Info: 2 years old.
Starting Seed Indoors:
Planting Seedlings Outside:
Your soil type will affect water needs. Carefully observing the plants and how long your soil remains damp is the best way to learn how to manage your unique conditions.
Many diseases that attack tomatoes, infect the plants when water stays on the plants for long periods or splashes up from the ground. Avoid getting water on leaves as much as possible. If you must water on cool cloudy days, wet the soil below the plants, ie. keep the leaves dry.
Seed Genetics: Hybrid.
Seed Collecting: Seeds will not come true but can still be collected. Plant's traits will vary. Plants may express traits not seen in the hybrid. If you want to prevent crossing with other tomatoes and even more genetic variation, bag an unopened flower with spun bonded row cover material. Remove when fruit starts forming. Mark stem with a string so you can find it later.
Why do they vary more?: Hybrid plants are heterogeneous meaning they carry dominant and recessive alleles for traits. What you see or taste is the effect of the dominant allele. This is represented by Bb were the B is the dominant trait, say black bean color. The b represents a recessive trait which, for this example we'll say is brown beans. Hybrids being Bb make black beans but when you collect their seeds you can get BB, Bb or bb. The bb plants will make you brown beans next year, not black.
Indeterminate: Plant will continue to set and ripen fruit until frost.
Staking: These plants cannot support their own weight. Use stakes, tomato cages or trellis if you want them to grow upright.
Growing on the ground: Plant the seedlings at about a 20-40 degree angle from the ground so the stem doesn't snap as the plant gets heavy.
Pruning: If you have a long growing season, indeterminates can get quite tall. Pruning the terminal leaves at the top of the plant will induce new branches to form lower on the plant and help control height.
If you are growing tomatoes as a perennial, biannual pruning will reduce the quantity of stems and leaves that are being supported by the root system and improve productivity.

Note: Germination performance is affected by many factors including temperature, package type, seed age, etc.. All our seeds are grown under the same conditions of moisture, temperature, soil content and light unless otherwise noted. This allows us to compare varieties so you can see which ones are easier to grow. But, since your conditions may differ, you may not experience the same results.
These are not statistically significant sample sizes. To do so would require we plant over 6000 tomato seeds! But we do have germination data from previous years. If data appears atypical, we'll note it.
