How to Grow & Care for Snowtopia Flowers

Snowtopias (Sutera cordata) are trailing, mounded plants with delicate white blooms that work well in containers, hanging baskets, rock gardens, mixed beds and as ground cover for small areas. Often confused with water hyssop, because of the shared common name "Bacopa," Snowtopia flowers are hardy to 32 degrees Fahrenheit and require little maintenance to maintain their beauty. Native to South Africa, Snowtopia plants, which bloom throughout the entire growing season, reach 2 to 6 inches in height, spreading up to 18 inches.

Instructions

  1. Starting Snowtopia Seeds

    • 1

      Fill the seed tray with slightly moistened potting mix, then sow one to two seeds on top of the soil in each plug.

    • 2

      Mist the entire tray to moisten seedlings and speed germination, then cover the tray with the plastic dome to create the necessary humidity required for growth. Ball Horticultural Company states that seedlings need relative humidity levels between 95 and 97 percent until the first leaves emerge.

    • 3

      Place the tray in a location that offers at least partial sunlight and maintains temperatures between 68 and 74 degrees Fahrenheit during the germination process, which typically takes four days.

    • 4

      Spray the seed tray regularly to maintain regular moisture during the early growth stages. Check trays daily and do not allow soil to dry out between mistings.

    Moving Snowtopia Outdoors

    • 5

      Choose locations outdoors that provide full to partial sunlight and nutrient-rich, well-draining soil. Texas AgriLife Extension Service recommends placing Snowtopia where there is full morning sun and afternoon shade to protect the delicate blooms during the warmer months.

    • 6

      Amend soil in the chosen planting locations with 2 to 3 inches of compost and coarse sand, in equal amounts, and a water-soluble, low-phosphorous fertilizer, following the manufacturer's recommended dosage. Use a shovel or garden trowel to thoroughly incorporate the amendments and break up any large soil clods. For container planting, incorporate the recommended dosage of fertilizer with enough sterile potting mix to completely fill the container. If the potting mix does not contain perlite, which helps with drainage, add 1/2 to 1 cup of coarse sand.

    • 7

      Space plants from eight to 20 inches apart in flower beds, depending on the desired visual effect. Snowtopia forms dense clumps, which can serve as a border if planted closely together. As an accent, alternate placement with other flowers and plants in the bed. In containers, decrease spacing to create a full mound that will grow together and spill over the edges.

    • 8

      Dig a hole approximately 2 to 4 inches deep. The base of the plant should sit even with the soil line when placed in the hole. Repeat this step for each seedling.

    • 9

      Insert the seedlings into the prepared holes, then pack soil into the remaining space in each hole and around the base of each plant. Gently pat down the soil to remove any air pockets.

    • 10

      Water the planting location gently to settle the Snowtopias into their new home. Once the plants are established, water regularly to keep the soil moist but not soggy. During drought conditions, check soil daily and water the plants as needed to prevent the soil from becoming dry.

    • 11

      Apply water-soluble, low-phosphorous fertilizer, following the manufacturer's recommended dosage, one week after transplanting the Snowtopias to their permanent location. Apply the fertilizer directly around the base of the plant, lifting the foliage up and away to avoid getting fertilizer on the leaves, which may cause burning and destruction of the foliage.

    • 12

      Snip or gently pinch off any discolored leaves or stems throughout the season.
