Tall Telephone
Pisum sativum 'Tall Telephone'
A classic heirloom shelling pea from the 1880s that remains beloved for its exceptional productivity and sweet flavor. This tall-growing variety produces an abundance of large pods filled with 8-10 tender, sweet peas that are perfect for fresh eating or freezing. Tall Telephone is the variety that made generations of gardeners fall in love with homegrown peas.

Complete Growing Guide
Start preparing your garden bed in early spring as soon as the soil can be worked. Tall Telephone thrives in rich, well-draining soil with a pH between 6.0-7.0. Work 2-3 inches of compost into the planting area and add bone meal at planting time — peas fix their own nitrogen, so avoid high-nitrogen fertilizers that promote leafy growth at the expense of pods.
Direct sow seeds 2-4 weeks before your last frost date when soil temperature reaches 45°F. Plant seeds 2 inches deep and 2-3 inches apart in rows spaced 6 inches wide. In zones 3-5, wait until mid-March to early April. Zones 6-7 can plant as early as February. Soak seeds overnight in lukewarm water before planting to improve germination rates.
Install your support system before or immediately after planting. Tall Telephone reaches 6-8 feet and requires sturdy trellising — a simple bean pole won't suffice. Use cattle panels, a strong A-frame trellis, or 8-foot posts with horizontal wires every 12 inches. The weight of mature plants loaded with pods will surprise you.
Once seedlings emerge, side-dress lightly with compost tea every 3 weeks. Water consistently but avoid overhead watering which encourages fungal diseases — soaker hoses work perfectly. Apply 2-3 inches of organic mulch around plants to retain moisture and suppress weeds, keeping mulch 2 inches away from stems.
The biggest mistake is underestimating their support needs. Plants will topple and break when loaded with pods if inadequately supported. Another common error is planting too late — peas hate hot weather and production drops dramatically once temperatures consistently exceed 75°F. In zones 8-9, focus on fall plantings instead.
Harvesting
Begin checking pods 10-12 weeks after planting when they're bright green, plump, and about 4-5 inches long. The pods should feel firm but give slightly when gently squeezed — this indicates the peas inside have reached full size but remain tender. Perform the 'pop test' by opening a sample pod; mature peas should be round, bright green, and sweet when eaten raw.
Harvest in early morning when pods are crisp and full of moisture. Pick pods with both hands — hold the vine steady with one hand while gently pulling the pod with the other to avoid damaging the plant. Tall Telephone produces heavily over a 3-4 week period, so check plants every other day once harvest begins.
Always harvest from the bottom of the plant upward, as lower pods mature first. Regular picking encourages continued production. If pods become pale green or start to wrinkle, you've waited too long — the peas inside will be starchy rather than sweet.
Storage & Preservation
Fresh peas deteriorate rapidly, converting sugars to starch within hours of harvest. For best flavor, shell and use immediately or refrigerate unwashed pods in perforated plastic bags for up to 3 days maximum. Store at 32-35°F with high humidity.
For freezing, blanch shelled peas in boiling water for 2 minutes, then plunge into ice water. Drain thoroughly and freeze in airtight containers for up to 8 months. Tall Telephone's large, uniform peas freeze exceptionally well and maintain their sweet flavor.
Dehydrating is another excellent option — blanch briefly, then dry at 125°F until wrinkled but not hard. These make excellent additions to soups and stews. You can also let some pods fully mature and dry on the vine for soup peas, though this stops further production.
History & Origin
Tall Telephone was developed in England during the 1880s, part of the Victorian era's fascination with improving garden vegetables through careful selection. The variety was named for the new invention of the telephone, as its tall growth habit supposedly resembled telephone poles — a cutting-edge technology at the time.
Introduced to American gardens in the late 1880s, Tall Telephone quickly became the standard by which all other shelling peas were measured. It dominated home gardens and small market operations well into the 1950s, before hybrid varieties began taking over commercial production.
This heirloom represents the pinnacle of 19th-century pea breeding — selected purely for flavor, productivity, and reliability rather than shipping qualities or machine harvest compatibility. Many modern gardeners consider it superior to contemporary varieties for fresh eating, which explains its enduring popularity among seed savers and heirloom enthusiasts. The variety has been maintained through continuous selection by gardeners for over 140 years, making it exceptionally well-adapted to diverse growing conditions.
Advantages
- +Exceptional productivity with 8-10 large peas per 4-5 inch pod
- +Superior sweet flavor that remains tender even when peas are fully developed
- +Extended harvest period of 3-4 weeks from a single planting
- +Excellent heat tolerance for an heirloom pea variety
- +Large, uniform peas perfect for freezing and maintaining quality
- +Strong vines that support heavy pod loads without breaking
- +Reliable germination even in cool, less-than-ideal spring conditions
Considerations
- -Requires substantial 6-8 foot trellising system, not suitable for small spaces
- -Takes 10+ weeks to harvest, longer than many modern varieties
- -Susceptible to powdery mildew in humid conditions without good air circulation
- -Production stops abruptly once hot summer weather arrives
- -Large plants can shade out nearby shorter vegetables
