Frequently asked questions

Frequently asked questions

What exactly is in a Spencer Mix packet?
The W.H. Perron packet, code 61-5990-010, contains approximately 100 bare Lathyrus odoratus Spencer Mix seeds. They are non-organic, and no coating or other treatment is stated. semences_biologique and semence_patrimoine are FALSE; semence_reproductible is TRUE because the product is not presented as an F1 hybrid. This is nevertheless a colour mixture, so saved seed may produce a different distribution the following year, especially after cross-pollination. Store the packet cool and dry, and label any saved seed with the harvest year and mixture name. The stated quantity remains approximate; count received seeds only when your planting plan requires absolute precision. before sowing.
How should seeds be prepared without damaging roots?
Lightly file or nick the seed coat, or soak seeds for 12 to 24 hours in room-temperature water. scarification is TRUE and stratification is FALSE: no cold treatment is required. Sow one or two seeds per pot at least 7 cm wide, 2 to 3 cm deep, and maintain 12–18°C. W.H. Perron lists emergence in 10 to 20 days. Sweet-pea roots are fragile, so harden seedlings and transplant the entire root ball without teasing it apart. Direct sowing after final frost avoids transplanting entirely and often produces sturdy plants where spring remains cool. Label every pot with its sowing date and monitor moisture daily without saturating the medium.
What site encourages long stems for bouquets?
Plant Spencer Mix in full sun and cool, moist, rich, well-drained soil. Incorporate compost before planting, space plants approximately 15 cm apart, and immediately provide a trellis or net nearly 2 m tall. Water deeply when the surface begins drying and mulch the root zone to preserve coolness. Avoid excessive heat against a hot wall and very high-nitrogen fertilizer, which favours leaves. Guide main shoots vertically and harvest often to maintain continuous production of long, straight stems suitable for arrangements. Protect roots from drying wind during early establishment. Airflow between plants also reduces foliar disease when weather remains cool and damp.
When should flowers be cut and how can flowering be extended?
Harvest early in the morning when the first flowers on a stem are open and upper buds show colour. Use clean scissors, place stems immediately in fresh water, and remove foliage that would be submerged. Cut or remove every faded flower and especially young pods because seed development quickly reduces new bud production. W.H. Perron specifically recommends removing developing fruit. Keep soil cool, harvest several times each week, and do not allow extended drought during the productive period. Refresh vase water regularly and keep arrangements away from ripening fruit for better vase life. For arrangements, condition stems in a cool place for several hours before arranging them.
Is Spencer sweet pea edible or safe for pets?
No. Ornamental sweet pea Lathyrus odoratus must not be confused with edible garden pea. Its seeds, pods, and other parts contain toxic compounds, so toxicite is TRUE, comestible is FALSE, and pet_friendly is FALSE. Never eat flowers or seeds even though the word pea sounds edible. Keep the packet, pods, and bouquet trimmings away from children and pets. After suspected ingestion or digestive, neurological, or weakness signs, promptly contact poison control, a veterinarian, or a health professional. Retain the packet so the exact plant can be identified. Do not use the flowers as edible decorations on plates, beverages, or desserts either.
