Learning Download:How to Grow Thunbergia

Thunbergia is native to eastern Africa, and it is a climbing plant. Since it is a vining plant, it can grow well in fence rows, on trellises, mailbox posts, in a hanging container or up lampposts.

Before Planting:The seeds are sown directly into the garden, but they can be started indoors six to eight weeks before the last frost. Amend soil with compost prior to planting.

Planting: Wait until the last frost has passed before directly seeding. Thunbergia seeds will take a while to germinate, up to 25 days.

Watering:Thunbergia does not tolerate drought well, so this is something to look out for especially in you are growing them in containers.

Fertilizer:Adding a general-purpose fertilizer every 4 to 6 weeks.

Days to Maturity:Thunbergia flowers will bloom from summer through fall.

Harvesting:Since they are a vining pant, these flowers are not great to harvest and display indoors.

Tips:These plants grow well in full sun or light shade, however, if you are planting them in a hotter region, it is best to make sure the plants receive afternoon shade.
