About
Ipomoea irwinae is a perennial climber with minutely rough, twining stems. Its distinctive leaves are round in outline, deeply divided into 7-9 linear, pointed lobes. The trumpet-shaped flowers are pink or mauve, reaching up to 7.5 cm in length, and develop into globose capsules containing hairy seeds. This species is native to Kenya and Tanzania, thriving in seasonally dry tropical biomes.
Where it works in Kilifi
This species is well-suited for Kilifi Coast gardens, thriving in full sun to partial shade and requiring well-drained soil. As a vigorous climber, it is ideal for covering trellises, pergolas, or fences, or as a striking specimen plant. It is found at altitudes from 0–500 m, making it suitable for coastal conditions.
Growing notes
Ipomoea irwinae is a fast-growing vine that prefers warm temperatures and consistent moisture during establishment, but once established, it demonstrates drought tolerance. Ensure well-drained soil to prevent root rot, as waterlogged conditions are detrimental. Protect from temperatures below 7°C.
