Morning Glory Grandpa Ott is an heirloom flowering vine suited to Pakistan’s warm spring and monsoon growing seasons. Its velvety purple trumpet-shaped flowers feature a vivid pink to ruby-red throat and a dark star-like pattern, creating a strong colour contrast when the vine is in bloom.

As an older open-pollinated variety, Grandpa Ott is valued for its traditional colouring and distinctive flower form. The vigorous twining vines grow best in full sunlight and can climb balcony railings, fences, trellises, arches and garden entrances, making them useful for quick seasonal cover.

💐 Growing Guide

1. Sowing
   • Gently scratch the hard seed coat or soak the seeds in water for 12 to 24 hours before sowing.
   • Use either method. You do not need to scratch and soak the same seed.
   • Sow the seeds ¼ to ½ inch deep and cover lightly with seed-starting mix.
   • Sow directly near a climbing support or start each seed in a small pot.
2. Germination & Transplanting
   • Keep the growing mix warm and lightly moist, but not waterlogged.
   • Move seedlings carefully when they have 2 to 3 true leaves.
   • Keep the soil around the roots together to reduce root disturbance.
3. Spacing & Container Size
   • Keep plants 8 to 12 inches apart.
   • For one plant, use a pot at least 10 to 12 inches wide and 10 to 12 inches deep.
   • Use a larger container when growing more than one vine together.
4. Sunlight, Support & Watering
   • Grow in full sunlight for healthy vines and better flowering.
   • Provide a railing, fence, trellis, arch or another climbing support from an early stage.
   • Water when the top layer of soil starts to dry. Keep the soil moist but not soggy.
   • During monsoon sowing, make sure pots and garden soil drain well.
5. Pests & Flower Care
   • Check the vines regularly for aphids, mites and other common garden pests.
   • Use neem oil only when pests appear.
   • Remove old flowers to help support continued flowering and reduce unwanted self-seeding.
