Name: Verbena (mix)
Height: 4 to 47 inches (120 cm).
Growing Region: Annuals: zones 1 to 10
Flowers: Late spring until the first frost.
Flower Details: Blue, violet, white, purple, rose, pink. Small. Five petals. Clusters. Spikes. Fragrant.
Foliage: Simple. Opposite. Hairy. Ovate. Lanceolate. Sometimes lobed; toothed.
Sow Outdoors: Cover stratified seed. Following the last frost. Spacing 6 to 40 inches (15 to 100 cm).
Sow Indoors: Mix seeds in a growing medium, place in a freezer bag, keep moist, then stratify by refrigeration for two weeks.
Germination time: two weeks to three months. Temperature 70°F (21°C). Nine or ten weeks in advance. Transplant outdoors a few weeks after the last frost; minimum temperature should not drop below 50°F (10°C).
Requirements: Full sunlight or light shade. Good drainage. Soil pH 6 to 7. Rich soil. Can survive in dry soils. Feed in spring. Regular watering. Pinch tips. Deadhead. Perennials should be brought indoors over winter in cold areas. Propagate cuttings in the spring.
How to grow:
If growing Verbena outdoors from seeds, then sow out following the last frost of spring, then lightly cover the seed. Due to the large variety in Verbena size, the spacing is species dependent, in general plant small Verbena about 20cm apart, medium Verbena at 30 to 40cm, and larger Verbena at 60cm to a meter apart. Ideally, Verbena should be grown in a fertile soil that is slightly acidic to neutral (pH 6 to 7). they like to grow in the sunny part of the garden, but can tolerate partial shade if needed.
If growing Verbena indoors first then sow about two months before the last frost. The Verbena seeds should first be sown into a pot; next cover with a plastic bag; put in the fridge for two weeks; then allow to germinate in the dark at a temperature of 18 to 24 degrees centigrade. Verbena seeds should take from two weeks to three months to germinate. Transplant the young Verbena plants outdoors a few weeks after the last frost of spring.
GERMINATION
Step 1 :
Step 2:
Place the verbena seeds in the hot water and stir them for up to two minutes with a spoon before draining the liquid.
Step 3:
Fill a bowl with lukewarm water that's between 86 and 104 degrees Fahrenheit and soak the seeds in it for 24 hours. This pre-treatment is called scarification and alters the hard seed coat, which increases the chances of uniform germination.
Step 4:
Fill a pot with the moist seed-starting mix up to 1 inch from the top, place the seed on top of the surface and cover it with a 1/2-inch layer of the mix. Tamp down lightly and moisten the surface with a water-filled spray bottle to avoid washing away the seed.
step 5:
Cover tightly plastic polythene wrap over the pot to promote soil moisture retention and place it in a dimly lit area of the house. Lift the plastic daily to check that the soil is moist. If not, lightly moisten it with a water-filled spray bottle before replacing the plastic. Expect germination within three to five days.
Step 6:
Remove the plastic as soon as the seedlings emerge, and gradually move the pot to a brighter area over a two-week period so that at the end of that time they're acclimated to being in full sunlight.
Step 7:
Transplant the seedlings outside to an area with full sun and well-draining soil after three to five months, when the seedlings are about 8 to 12 inches tall.
IMPORTANT WATERING USE: Use watering can for watering. By moving the water stream constantly waves the can. Do not let the water to flood in particular area. Or use the sprayer to spray the water like mist.
GERMINATION CARE
After the seedlings germinate, they can relocate to a sunny south- or west-facing window. The soil is kept moist at all times, but not allowed to get soggy. Once the seedlings have three true leaves, they are fed every two weeks with a liquid houseplant fertilizer. Pinching out the growth tips isn't necessary.
