PLACEMENT & CULTIVATION
This morning glory family member has arching sprays of tubular flowers that change from crimson to butter-yellow, giving a delightful multi-colored effect. Grow Spanish flag in a large pot with a trellis for the twining stems to catch hold, and fertilize only with low nitrogen flower fertilizer as the first buds start to form. Best in a warm, sheltered spot, where it will twine upwards and start to flower late summer to frost. Caution: seeds contain some toxic alkaloids.
Watering Details:
About 1" per week, more during especially dry, hot spells.
Soil pH:
Slightly acidic to slightly alkaline.
Fertilizer:
Mix in 2" of compost prior to planting and apply a flower fertilizer at bud set for more abundant blooming. Avoid nitrogen fertilizers that favor foliage growth over flower development.
Diseases & Pests:
Avoid fungal troubles by spacing properly and planting in a location that has decent air circulation.
