Calamint Sowing Instructions
Planting Depth
:1/16”
Seed Spacing:1”-2”
Plant Spacing:10”-12”
Days to Germination:14-21 days
Germination Temperature:70°-75°F

Calamintha nepeta. Bees and butterflies adore this aromatic, sun-loving, deer-resistant perennial. Broad spikes of tiny tubular flowers smother the trouble-free, gray-green, minty foliage from mid summer to fall. Sow seeds indoors, 6 to 8 weeks before transplanting out into the garden. Press the seeds into the soil surface and keep them moist until germination. Harden off the seedlings by slowly introducing them to the outdoors over the span of a week, and then plant them out into the garden, 10" to 12" apart, after all danger of frost has passed, in full sun to partial shade and well draining soil. Calamint is quite drought-tolerant and makes a wonderful edging and rock garden plant. It also blooms the first year from seed! Perennial. Summer to fall blooming. Height: 8" to 10".

Coneflower Sowing Instructions
Planting Depth
:1/4”
Seed Spacing:1”-2”
Plant Spacing:18”-24”
Days to Germination: 10-20 days
Germination Temperature:65°-75°F

Echinacea purpurea. Start Coneflowers indoors before the last frost date to promote first-year blooms. Soak seeds in warm water for 24 hours, and then sow in a good seed-starting medium. Provide 65° to 75°F temperatures and uniformly moist soil until seedlings emerge. Introduce strong sunlight. Once seedlings are large enough to handle, transplant to larger, deeper pots for full root system development. After all danger of frost has passed and seedlings are 4" tall, harden them off by gradually acclimating them to the outdoors over 7 to 10 days. Transplant out 18" to 24" apart or direct-sow in rich, well-draining soil and full to partial sunlight. Water regularly and mulch to deter weeds and retain ground moisture. Deadhead old flowers to promote continuous blooms. Summer flowering.

Coreopsis Sowing Instructions
Planting Depth
:1/8”
Seed Spacing:1”-2”
Plant Spacing:12”
Days to Germination:10-25 days
Germination Temperature:55°-70°F

Coreopsis grandiflora, Tickseed. An easy-to-grow perennial (even in poor soil), Coreopsis will produce little, daisy-like flowers amid feathery foliage the first year if started early enough, 8 weeks before transplanting out. But it may be sown outdoors anytime from early spring up until 2 months before the first fall frost. Sow seeds shallowly, pressing them firmly into the soil surface, barely covered, as light is needed for germination. Provide even moisture and strong light during germination. Harden the plants off by gradually acclimating them to outside conditions over 7 to 10 days. Prepare a garden bed in full sunlight with well draining soil. Thin or carefully transplant the seedlings, planting them 12" apart. Coreopis should be kept moderately moist and deadheaded to prolong its flowering period. Summer flowering. Height: 24".
Hibiscus Sowing Instructions
Planting Depth
:1/4”
Seed Spacing:12”-15”
Plant Spacing:24”-30”
Days to Germination:15-30 days
Germination Temperature:65°-75°F

Hibiscus mosheutus. Hibiscus can be direct-sown outdoors in warm areas or started indoors 8 to 10 weeks before transplanting outside after the threat of frost has passed. Soak seeds in water: once they sink, they are ready to plant. Sow seeds in good seed-starting medium at 70°F with even moisture, strong light and good ventilation. For consistent moisture during germination, cover the flats or pots with plastic wrap until seedlings emerge: then discard plastic. Harden off the seedlings by gradually acclimating them to outside conditions for 1 to 2 weeks before transplanting outside. Hibiscus are moisture-loving plants. Mulch to conserve moisture, water consistently and fertilize as necessary. Intolerant of night chills, bring potted plants indoors before a hint of fall frost. Summer flowering. Height: 24" to 36".
Hyssop Sowing Instructions
Planting Depth
:1/8”
Seed Spacing:2”-3”
Plant Spacing:18”
Days to Germination: 5-20 days
Germination Temperature:70°-75°F

Agastache rupestris. Hyssop should be direct-sown after the threat of frost has passed. Sow seeds on top of the soil, leaving the seeds uncovered but pressed firmly onto the soil surface, as light aids germination. It may also be raised as transplants 8 to 10 weeks before the last spring frost date, with even moisture, strong light and air circulation. Harden off the seedlings by gradually acclimating them to the outdoors for a week to 10 days. Prepare a bed in full sunlight with rich, well-draining soil. Thin or transplant to 18" apart. Transplants should be watered regularly to help establish a mature root system for first-year blooms. Once established, it is drought tolerant. Its compact plants have dozens of sturdy spikes studded with tubular flowers. This valuable cut flower is adored by bees, hummingbirds and butterflies. Summer flowering. Height: 1 1⁄2' to 2'.

Maltese Cross Sowing Instructions
Planting Depth
:1/16”
Seed Spacing:2”-3”
Plant Spacing:12”-15”
Days to Germination:21-25 days
Germination Temperature:70°-75°F

Lychnis chalcedonica. Butterflies, hummingbirds, and gardeners all love this old-fashioned, easy-to grow, deer-resistant perennial. Its bright scarlet orange flowers, borne in dense clusters atop tall stems, positively glow in full-sun plantings. Sow seeds indoors in spring, 6 to 8 weeks before the last frost. Barely cover the seeds with soil, since they require light to germinate, and then keep them moist until germination. Harden off the seedlings by slowly introducing them to the outdoors over the span of a week, and then transplant up to 15" apart after all danger of frost has passed. Maltese Cross prefers consistently moist soil once transplanted outdoors. It’s an excellent cut flower, and cutting and deadheading will prolong its bloom period. Perennial. Summer flowering. Height: 2' to 3'.When the blooms begins to fade, cut the plant back to encourage new growth.

Red Hot Poker Sowing Instructions
Planting Depth
:1/4”
Seed Spacing:2”-3”
Plant Spacing:18”-24”
Days to Germination:10-20 days
Germination Temperature:70°-75°F

Kniphofia uvaria. A.K.A. Tritoma or Torch Lilies, Red Hot Pokers love sun and heat, and are perfect for that baking area beyond the reach of your water hose. Moisten seeds and then store them, wrapped in plastic, in a cold place for 4 weeks before sowing them indoors, 6 to 8 weeks before the last frost date. Keep the seeds moist until germination. Harden off the seedlings by slowly introducing them to the outdoors over the span of a week, and then transplant them after the last frost date to 12” apart in full sun and well-draining soil. If the hummingbird-beloved flowers are allowed to mature, the songbirds will make a meal of the seeds, though the seeds that elude them may sprout where they fall next spring. The tough, grassy foliage is evergreen but may get a bit battered in winter. Remove tattered leaves in spring.
