Pink & Yellow Mix Four O' Clock

Pink and Yellow Mix Four O' Clock is a festive mix of rose pink and sunny yellow 2-inch blooms that last all night long! This shrub-like 2-3-foot tall plant is adorned with trumpet-shaped flowers that fill the night air with a sweet, jasmine-like fragrance. Four O' Clock flowers have the unique ability to change color as they age, often resulting in a stunning gradient of hues on the same plant. Plant in spring after the last frost, and watch as they bloom from summer until fall while adding evening charm to your garden. Four O' Clock flowers get their name because they typically open around 4 PM and stay open throughout the night. Besides its ornamental value, the flowers can also be used to create natural dyes.

Planting Instructions:

Soil Preparation:

Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 6-8 inches deep. Loosening the soil will help the plant establish strong roots. If the soil is heavy or clay-like, mix in some sand or compost to improve drainage. Optionally, form rows of soil beds 4-6 inches high and at least 18 inches apart. This formation of ridges will help with drainage, ensure good airflow, and make harvesting for cut flowers easier. Lay down 1/2"-3/4" peat moss, sawdust, or potting soil, the soil surface. This layer is beneficial for flower seeds because it can the improve the germination environment and prevent soil crusting.

Planting:

Starting Indoors: For earlier blooms, you may optionally start planting indoors in containers 6-8 weeks before the last expected frost date in Spring, keeping seedlings at least 65F. Harden off then transplant seedlings outdoors in a sunny location when temperatures are consistently above 60F. To transplant seedlings, prepare a transplant hole outdoors in a sunny location. Remove the plants carefully from the pots or flats and set them in the transplant holes, burying some of the stem in the ground. Pack the soil loosely around the plant and leave a slightly sunken area around each plant to hold water. Water the plants after transplanting.

Directly Sowing: If directly sowing outdoors, plant after all danger of frost has passed in spring and soil temperatures reach at least 60F. Fall planting is not recommended unless planting outdoors in environments with mild, frost-free winters, or planting indoors with supplemental grow lights. If fall planting, plant in containers to prepare to store plants indoors over winter.

To plant, make holes 1/2 inch deep and spaced 1-2 feet apart down the rows of raised beds. Plant 2-3 seeds per hole, then cover thinly with soil. In small plots, flower seeds may be scattered and gently watered in. Once seedlings emerge, plants can separated and spaced 1-2 feet apart to allow room for mature plants to spread and prevent overcrowding. Water after planting.

Planting Depth:	1/2 inch
Within-Row Spacing:	1-2 feet
Between-Row Spacing:	18-24 inches

Care During the Season:

Four O' Clocks enjoy moderate watering and are somewhat drought-tolerant once established. Optionally, apply a balanced fertilizer every few weeks to support healthy growth and flowering. Deadheading spent flowers isn’t necessary, as the plant self-seeds readily. However, if self-seeding is undesirable, remove developing seed pods. In warmer climates (USDA zones 7–11), Four O' Clocks grow as a perennial, with its tuberous roots surviving winter dormancy. In colder regions, mulch the roots heavily in fall or dig up tubers before the first frost, storing them in a cool, dry place for replanting in spring.
