Time to Sow More Flowers

Lobelia seeds snug in their pots ready to go under growlights!

I hope to add a wider variety of flowers to my flower bed this year.  In my opinion, planting perennials have a slight advantage over annuals; once well-established, perennials come back year after year saving time, energy and expense.  But, at the same time, annuals can't be beat for having more flower production and a longer blooming period. Not to mention, too, that annuals quickly add color where you need it.  
Following are the seeds I sowed today:

Hibiscus (Disco Belle): Seed swap, 2009.  Planted 5-7 seeds in two 2" pots 1/4" deep.  Expected germination time, 14-21 days.  Characteristics: perennial, large, light pink flowers with burgundy eyes, 36" tall bush, flowers short-lived, continuous supply of flowers from summer until first frost, blossoms the first year.

Hibiscus (White): Harvested, 2014; originally received from an online seed swap, 2009. Planted 5-7 seeds in five 2" pots 1/4" deep. Expected germination time, 30 days. Characteristics: perennial, large, white, dinner-plate-sized flowers, flowers short-lived, continuous supply of flowers from summer until frost, blossoms the first year.

Lobelia (Crystal Palace, Palacio cristal, Lobelia erinus): Ferry-Morse, 2015. Planted twenty-five 2" pots, covering seeds 1/4" deep as recommended on the packet.  In response to online research stating that lobelia seeds required light to germinate, I sprinkled additional seeds on top of the seeding mix. Expected germination time: 15-20 days. Days to bloom, 60-77. Characteristics: annual, 4"-6" tall, sun to partial shade, dainty, cobalt blue blooms, bronze-colored foliage, suitable for containers, spaced 6" in the garden, enjoys cool weather, blooms all summer if well watered. I intend to prepare a few hanging baskets this season and use the lobelia in window boxes.

Verbena (Florist, Mixed Colors): Ferry-Morse, 2015. Planted fifteen 2" pots 1/8" deep. Expected germination time, 14-20 days.  Days to maturity, 55-80.  Characteristics:  annual, hybrid, sun to partial shade, 8-12" tall, space 12" apart in garden, multicolored, fragrant flowers, blooms up to 11 weeks.

Vinca (Colores Mixtos):  Ferry-Morse, 2015. Planted twenty-five 2" pots, burying seed 1/8" as recommended on the packet.  Online sources state vincas need total darkness to germinate. I am concerned the 1/8" may not provide adequate coverage.  I'll cover the containers with cardboard until I see signs of germination. Expected germination time, 14-21 days.  Days to maturity, 84-98.  Characteristics: annual, full sun, 12-15" tall, spacing 10", mix of pink and white single blossoms that bloom until frost, an old-time favorite, excellent for beds and borders, highly tolerate of heat/drought, humidity/moisture.

Postscript #1 - Today, after two weeks in the refrigerator, the delphinium and lavender containers were ready to join the seed trays on the shelving unit in front of the slider. I will watch their germination carefully to determine if pre-chilling the seeds aided in germination.  I'll keep you posted!

Let the Seeding Begin!

I started seeds today knowing perfectly well that I am very early even for these varieties:

Delphiniums (Pacific Giant, Delphinium elatum): Seeds purchased from Livingston Seeds. Planted these seeds 14 weeks before last frost; 10-12 weeks were recommended.  Seeds were chilled in the refrigerator for a week prior to being sown.  Sowed two 4"x8" containers, approximately 50-55 seeds in each one, 1/4 inch deep (darkness required).  As part of an experiment to determine if continued chilling assists in germination, one container was placed in the refrigerator for two weeks while the other was not. Expected germination time: 25-30 days. Characteristics: perennial, full sun, 4-5' tall (back border), blooms in summer, pastel pink, lavender, white and blue spires, staking may be needed, thought to be difficult to sprout. See http://www.mr-fothergills.co.uk/Flower-Seed/Delphinium-Seed/Delphinium-Pacific-Giants-Mixed.html#.VNDdv9X3-iw.

Pansy (Swiss Giant Mix, Viola wittrocklana): Seeds purchased from Livingston Seeds. Planted pelletized seeds 14 weeks before last frost; 10-12 weeks were recommended.  Sowed one 4"x8" container, approximately 80 seeds, 1/4 inch deep (darkness required).  Expected germination time: 3-9 days since pelleted, most generally 14-28 days. Characteristics: annual, full sun, 6-8" tall (front border), blooms in spring, rainbow of colors, fragrant, large blooms, compact plants for use in containers. See http://www.mr-fothergills.co.uk/Flower-Seed/Summer-Flowering/Pansy-Swiss-Giants-Mixed_2.html#.VNDqH9X3-iw.

Rosemary (Rosmarinus officinalis): Seeds purchased from Livingston Seeds. Planted pelletized seeds 14 weeks before last frost; 8 weeks was recommended.  I will likely have to "pot up" before planting out in the garden in mid May. Sowed two 4-packs, approximately 8 seeds each cell, planted 1/4" deep (darkness required). Expected germination time: 5-7 days since pelletized; most generally 14-21 days. Characteristics: tender perennial, evergreen shrub, full sun, plant in containers or in herb garden, fussy to sprout. See http://www.johnnyseeds.com/p-8172-rosemary.aspx.

Lavender (Vera, Lavandula vera ):  Livingston Seeds. Planted seeds 14 weeks before last frost; 6-8 weeks were recommended.  Sowed three 4"x8" containers, approximately 45 seeds each.  The seeds in one container were pressed into the seed mix (surface sown, light required).  The seeds of the second container were covered 1/4" with seed mix as suggested on the packet.  A third container was placed in the refrigerator for a few weeks; a few sources had recommended chilling. Expected germination time: 14-21 days or up to a month. Characteristics: perennial, full sun to partial shade, 18-24" (mid-border), bushy/hardy variety.

TIP OF THE DAY!!  Collect clean water as you sow seeds.  Simply place a basin under the faucet as you rinse your hands, tools, trays, etc. This water may be used to wet potting mix or water seedlings.

Postscript #1 -  Small white roots in both sweet potatoes have emerged.
