It is advisable to grow the plant in areas with warmer climates. However, in areas with colder climates, it can be grown in containers indoors or outdoors, provided it is protected from frost and extreme temperature fluctuations.
Soil Requirements
Gratiola aurea Pursh var. obtusa Pennell requires well-drained soils with a pH ranging from 5.5 to 7.5. The soil must be rich in organic matter, and it should not be compacted. The plant is tolerant of drought conditions but not flooding. Excessive moisture may result in root rot and the eventual death of the plant. When planting, it is recommended to add a slow-release fertilizer that is high in phosphorus to boost root development and promote flowering.
Cultivation of Gratiola aurea Pursh var. obtusa Pennell
Gratiola aurea Pursh var. obtusa Pennell can be grown outdoors in USDA hardiness zones 5 to 9. This herbaceous plant prefers full sun to partial shade and well-drained soils with moderate moisture. It can tolerate dry soil for a short duration.
The optimum soil pH for growing Gratiola aurea Pursh var. obtusa Pennell is 6.0 to 7.0. The plant can grow up to 18 inches tall and 12 inches wide, producing yellow flowers in the summer.
Watering Needs of Gratiola aurea Pursh var. obtusa Pennell
Gratiola aurea Pursh var. obtusa Pennell requires regular watering during the growing season. Water the plant when the top 2 inches of soil feel dry. However, do not overwater the plant, as excessive moisture can cause root rot.
The plant can tolerate short periods of drought, but prolonged drought can damage the foliage and reduce the flowering capacity.
Fertilization of Gratiola aurea Pursh var. obtusa Pennell
Gratiola aurea Pursh var. obtusa Pennell does not require frequent fertilization, but a balanced fertilizer application in the early spring can enhance the plant's growth and flowering. Use a slow-release granular fertilizer with an NPK ratio of 10-10-10 or 20-20-20, following the manufacturer's instructions.
Over-fertilization can cause excessive foliage growth at the expense of flowering.
Pruning of Gratiola aurea Pursh var. obtusa Pennell
Gratiola aurea Pursh var. obtusa Pennell does not require significant pruning, but removing the faded flowers and discolored foliage can improve the plant's aesthetics and prevent disease spread. Use clean and sharp pruning shears to make clean cuts.

Propagation of Gratiola aurea Pursh var. obtusa Pennell
Gratiola aurea Pursh var. obtusa Pennell, commonly known as Golden Hedgehyssop, can be propagated through seeds and cuttings.
Propagation through seeds
The easiest way to propagate Gratiola aurea Pursh var. obtusa Pennell is through seeds. The plant produces small seeds that are best sown in the early spring when the soil temperature reaches around 60°F. The seeds can be sown directly into the garden bed or in pots filled with seed-starting mix. The seeds are very small and should be sown thinly on the surface of the soil. After sowing, cover the seeds lightly with soil and water gently. The seeds will germinate in two to three weeks.
Propagation through cuttings
Another way to propagate Gratiola aurea Pursh var. obtusa Pennell is through stem cuttings. Take stem cuttings in the summer when the plant is actively growing. Use a sharp, clean pair of pruning shears to take a cutting about 4 to 6 inches long. Remove the lower leaves from the cutting and dip the cut end in rooting hormone. Insert the cutting in a pot filled with a well-draining rooting medium like perlite or sand. Water the cutting and cover the pot with a plastic bag to create a humid environment. Place the pot in a bright, indirect light and keep the soil moist. The cutting will root in three to four weeks.
Disease and Pest Management for Gratiola Aurea Pursh var. Obtusa Pennell
