About Solanum crispum 'Glasnevin'

Solanum crispum 'Glasnevin' · also called Glasnevin Chilean potato tree, Chilean potato vine · flowering

Solanum crispum 'Glasnevin' is a vigorous, semi-evergreen scrambling climber prized for clusters of star-shaped, purple-blue flowers with bright yellow centres borne from summer into autumn. It is one of the hardiest Solanums, needing a warm, sheltered wall, full sun, and tying-in to support as it does not self-cling. All parts are toxic if eaten.

Ideal humidity: Ambient outdoor

Watch for — Aphids: Soft new shoots attract aphids, which distort growth and leave sticky honeydew. Dislodge with water or treat early; encourage ladybirds and other predators.

The base rhythm for solanum crispum 'glasnevin' is keep evenly moist in the first two seasons; water established plants during prolonged dry spells, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.

Once established it is reasonably drought-tolerant in open ground. Water deeply in summer droughts and avoid waterlogging, which it dislikes. Container plants need regular watering.

How to tell solanum crispum 'glasnevin' needs water

A calendar is the worst way to water solanum crispum 'glasnevin'. Check the plant and the soil instead — for this species, look for these signals in order:

Leaves or flower stems lose turgor and start to droop.
Buds stall or the pot feels light.

Wilting, bud and flower drop, and crispy leaf edges.
A faded, stressed look and a rootball that has pulled from the pot sides.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For solanum crispum 'glasnevin', the levers that matter most are:
