The Annual Plant Collection
The annual plant collection is a variety of 24 plants. These varieties have been selected specifically to coordinate with each other and will look amazing in any annual flower bed or cut flower garden.
All of the plants have been seeded and grown onsite in the Piscasaw Gardens Greenhouse. All plants will be seeded in February and transplanted to your tray in March. They will be ready for pick up the first two weeks of May. We will make official updates and announcements on the plants as their pickup date approaches. Orders must be submitted by March 4, 2022.
The annual plant collection consists of (mixed colors):
4 Plants of Zinnas
4 Plants of Lisianthus
4 Plants of Snapdragons
4 Plants of Celosia
4 Plants of Statice
4 Plants of filler flowers (Ammi, gomphrena, ageratum, strawflowers)
Lisianthus: Plant your lisianthus in a spot that boasts full sun, where the plant can get at least six to eight hours of sunlight a day. Choose a planting site with well-draining soil. The soil should be well-draining and should not remain waterlogged, as that can lead to root rot. Lisianthus plants prefer a soil PH between 6.5 and 7.0.
Snapdragons: Once they're established, give them 1 inch of water per week. Water at the roots of the plants. Mulch plants to keep down weeds and hold moisture in the soil. Once summer heat kicks in, mulch will help keep the roots cool and the plants healthy until they get their second wind in the fall and bloom again. Stake taller varieties so they don't fall over under the weight of those stalks of flowers. Prune spent blooms during the spring to keep the snapdragons blooming.
Celosia: Celosia plants require a minimum of eight hours of direct sunlight and soil that drains quickly. Celosias will grow in nutrient-poor, sandy soil but thrive and bloom more profusely in soil that contains high levels of organic matter. Soil pH levels between 6 and 6.5 are best. Celosia can be planted in the garden in the spring when temperatures will remain above 60 degrees Fahrenheit. They will be damaged if the temperature drops lower than that.
Statice: Statice prefer warm weather and sandy soils but will tolerate any well-draining soil provided it is not too rich with nutrients. Plant them in full sun, 12 to 15 inches apart. Statice require little in the way of supplemental water and no supplemental feeding.
Ammi: Full sunlight or light shade. Good drainage. Rich soil. Moist soil. Water during prolonged dry periods. Transplant outdoors following the last frost. Do not confuse with Queen Anne's Lace from the Daucus genus.
Gomphrena: Position gomphrena plants in full sunlight. Although the plants tolerate partial shade, full sun makes for more vibrant blossoms. These bedding flowers aren't picky about soil type, but it's best to plant them in well-drained soil during spring. Gomphrena prefers soil with a pH range of about 5.8 to 6.2 and needs about 12 to 18 inches of space.
Ageratum: They don't require a lot of feeding when planted in good, rich soil, but if the leaves begin to turn yellow, it's a sign they need nutrients. Plant ageratum in well-drained but moist soil that has been amended with compost. It is not fussy about soil PH. About 1 inch of water per week from rainfall and/or irrigation will keep them healthy.
Strawflowers: Strawflowers thrive in full sun, although they can tolerate part shade. Sandy and rocky soils are preferred over rich and heavy soils, but any soil is fine as long as excellent drainage is present. A weekly drink will keep the flowers pert and fresh. Give them about 1 inch of water a week during the growing season if the rain hasn't already kept the soil moist. Strawflowers do best in temperatures of 65 to 70 degrees Fahrenheit during the day and 60 degrees at night.
