Alcea rosea: Single Red Heirloom Hollyhock  Sowing Instructions: Best if direct sown in the garden where they are to grow. Can also be sown indoors 6-8 weeks before the last frost date. Use good quality seed starting mix. Plant the seeds 1/8” deep and moisten. Germination should occur in 10-21 days.

Campanula medium var. calycanthema: Canterbury Bells — Sowing Instructions: Sow outdoors anytime during the spring or the fall. Indoors sow 10-12 weeks before the last frost date in your area. Sow seeds on the surface of good seed starting soil. Place at 60-70°F. Germination should occur in 14-21 days. Does not flower the first year. Flowers the second year. Save some seeds and sow them next year so that you’ll never be without blooms. (biennial)

Capnoides sempervirens: Pale Corydalis — Sowing Instructions: Sow indoors 8 weeks before last frost date in your area. Barely cover the seeds in seed starting material. Sow at 68-72°F. Germination should occur in about 16 days. Can also be planted outside where you’d like for them to grow and bloom. (biennial)

Dianthus barbatus: Sweet William — Sowing Instructions: If sown in autumn, a few plants may bloom in spring. Most will grow and then bloom in a year. Best sown in rich garden soil where they’re intended to grow. If seeds are sown in ideal conditions in a sunny location the plants will reseed themselves and bloom again from year to year. Plant seeds 1/16” beneath the soil in a sunny location once the soil has warmed up in late spring. Germination should begin in 14-30 days. (Can be sown in outdoor pots too.)

Digitalis purpurea: Common Foxglove — Sowing Instructions: Sow indoors eight weeks before the last frost date in your area, or outdoors after lost frost date. Sow seeds on the surface of moist seed starting soil.  (If sown indoors, seeds should sprout at room temperature after a few weeks.) Later plant out 12” apart in full sun and ordinary well-drained garden soil. (biennial)

Euphorbia lathyris: Gopher Spurge — Sowing Instructions: Soak in warm water for 2 hours before sowing. Euphorbia don’t like to be transplanted so it’s best to sow them where they’re to grow or use deep pots or plugs. Keep at room temperature and seeds should germinate in 2-3 weeks, but some may take several months. (biennial)

Heracleum maximum: Cow Parsnip — Sowing Instructions: Seeds should be sown into peat pots in the autumn. Sow where they’re going to grow. If sowing in spring, sow seeds in pots, wrap in a plastic bag, then stratify in the refrigerator for 3 weeks. Place outdoors. Once seedlings emerge, remove the covering. Transplant them to where they’ll grow. (biennial)

Lunaria annua: Money Plant — (both the standard and variegated) — Sowing Instructions: Plant after last frost in situ in a location that receives plenty of sunlight. Plant ½” (13mm) deep. Germinates in 10-20 days. Will flower the second year.  Plant annually for ongoing blooms. (biennial)

Rudbeckia hirta: Black-Eyed Susan — Sowing Instructions: Can be sown outdoors 2 weeks before last frost date. Sow on the top of the soil. Seeds should germinate in 2-3 weeks. Indoors, start 6-8 weeks before the last frost date. Sow on the surface of moist seed starting soil and keep at 70-75F. For best results, keep in a plastic bag and give plenty of light. Remove the bag when seeds begin to germinate.

Seseli gummiferum: Moon Carrot — Sowing Instructions: Sow at 68°F just under the surface of damp seed starting soil mix. If no germination occurs after 4-6 weeks, move to 24-39°F for several weeks. Can also be planted in the garden where they’re intended to grow. Sow 2-4 weeks before the last frost date in your area. (biennial)
