Sunset's Red Horizon is a distinctive heirloom variety recognized for its large, red, heart-shaped fruits and dense, meaty flesh.

Its indeterminate growth habit also allows the plant to continue producing fruits throughout the growing season under suitable conditions.
Red Horizon tomatoes commonly produce large fruits measuring approximately 4–6 inches across. Their characteristic heart-shaped appearance and thick, meaty flesh make them particularly attractive for slicing, sandwiches, and fresh tomato dishes. Individual fruit size and weight depend on growing conditions, watering, nutrition, and plant care.
Yes, Red Horizon is considered a useful choice for gardeners looking for a large-fruited heirloom tomato with relatively early maturity. It generally takes around 72–75 days from transplanting to produce ripe fruits. Starting seeds indoors or in a protected growing area can help gardeners make better use of shorter growing seasons.
Yes, Red Horizon can be grown in a large container with adequate drainage, fertile potting mix, and sufficient sunlight. Because it is an indeterminate variety with vigorous vines, choose a spacious, sturdy container and provide a strong support system. Regular watering and feeding are especially important for container-grown plants.
Use a strong tomato cage, stake, or trellis to support the vigorous indeterminate vines and their heavy fruits. Tie the main stems loosely to the support as the plant grows. Remove damaged or diseased leaves and manage side shoots according to your preferred growing system. Good airflow helps maintain healthy foliage.
Sunset's Red Horizon is an open-pollinated heirloom variety. Seeds can generally be saved from fully ripe, healthy fruits and stored for future planting. For better seed quality, select fruit from healthy, true-to-type plants, ferment the seeds to remove the surrounding gel, rinse thoroughly, and dry completely before storing in a cool, dry location.
