Morning Glory Grandpa Ott produces velvety deep-purple flowers with a pink to ruby-red star around a pale throat. Its heart-shaped green leaves and twining stems create colourful cover for fences, trellises, arches and balcony railings.

This traditional heirloom variety has been preserved by gardeners for generations. It grows strongly during warm weather, winding around supports and producing fresh flowers throughout its flowering season.

Sowing note: In Lahore and Faisalabad, sow from February to April once cold weather has eased. In Islamabad and Rawalpindi, sow from March to May after frost has passed. In Karachi and southern Punjab, sow from February to March, or again from August to September when extreme heat and heavy rain have eased. In colder northern and hilly areas, sow from April to June once the soil has warmed.

How to Sow

1. Soak the seeds in lukewarm water for 12–24 hours, then drain.
2. Loosen the soil beside a support, or fill the final pot with moist potting mix.
3. Make holes around ½ inch deep and place one seed in each.
4. Cover with fine soil and water gently without washing the seeds away.
5. Keep the surface lightly moist until the seedlings appear.
6. Guide the young stems towards the support as they begin growing.

Plant Care

Water thoroughly when the upper layer of soil begins drying. Keep young plants evenly moist while their roots establish. Guide spreading shoots onto the support and trim any stems growing into nearby plants or pathways.

Mix a small amount of Vermicompost into the soil before sowing. Avoid excessive nitrogen feeding, which encourages leaves at the expense of flowers. Check for aphids, whiteflies and spider mites. If pests appear, apply Neem Oil at its labelled dilution during the cooler part of the day.

Local Gardener Tips

• Install the support before sowing to avoid disturbing established roots.
• Protect newly sown areas from heavy monsoon rain.
• Keep rooftop pots sheltered from strong winds.

Flowering and Display

The flowers open in the morning and usually close as the day becomes hotter. They may remain open longer during cloudy or cooler weather.

Use vertical strings, netting or a trellis to spread the stems across the display area. Remove developing seed pods if extra seedlings are not wanted around the garden.

FAQs

What if the seeds remain hard after soaking?

The seed coat may still be preventing water from entering. Lightly rub a small patch with fine sandpaper without exposing the inside, then soak again before sowing. Avoid cutting deeply into the seed.

Can I save seeds from Grandpa Ott?

Yes. Allow selected pods to turn brown and dry, then collect the mature seeds and store them somewhere cool and dry. If other Ipomoea purpurea varieties flower nearby, cross-pollination may produce different colours in the next generation.

Will the same vine return after winter?

Grandpa Ott is usually grown as an annual. Frost can kill the vine, although it may live longer in warm, frost-free conditions. Seedlings appearing later may be new plants from fallen seeds.
