Clematis x hybrida 'Kimi'idera'

The Story

Plant Bio

Clematis species are deciduous or evergreen woody vines that climb by wrapping their leaf petioles around slender supports. They require moist, highly permeable soils and benefit from having their root zones shaded while their upper foliage receives sunlight.

'Kimi'idera' is a compact Japanese cultivar featuring large, star-shaped flowers with white petals edged in pale blue-violet and contrasting reddish-purple anthers. It produces a heavy primary bloom on old wood in spring, followed by a secondary flush on new growth in late summer and fall.

Uses & Benefits:

Produces large, bi-colored star-shaped flowers that provide a dramatic vertical display on trellises, fences, or obelisks.

Compact growth habit makes it highly suitable for container culture and small-scale urban gardens where space is limited.

Flowers attract and support native bees, beneficial insects, and general pollinators during spring and late summer.

Planting

How to Grow

Select a planting site that receives full sun to partial shade, ensuring the base of the plant can be shaded by companion plants or mulch.
Dig a hole twice the width of the root ball and amend the soil with organic matter to ensure rich, fertile, and exceptionally well-drained conditions.
Plant the clematis with the crown positioned roughly one to two inches below the soil surface to encourage deep root development and shoot regeneration.
Install a trellis, wire, or netting immediately, as the twining leaf petioles require thin supports to climb effectively.
Water deeply and regularly to maintain consistent soil moisture, avoiding waterlogged conditions that lead to root rot.

Pro Tip

Pruning this Group 2 hybrid too harshly in early spring destroys the old wood required for the primary flower crop; limit spring pruning to removing dead wood and trimming remaining stems back to strong, healthy buds. Shading the root zone with deep mulch or low-growing companion plants prevents the soil from baking in midday heat.

Keep It Thriving

Care Guide

Do

Mulch the root zone heavily to keep the soil cool and retain consistent moisture.
Apply a balanced, slow-release organic fertilizer annually in early spring.
Prune lightly after the spring bloom to encourage a secondary flush of flowers in late summer.

Don't

Do not cut the vine back hard to the ground in early spring, as this removes the old wood needed for spring flowering.
Do not allow the soil to dry out completely, especially during hot summer spells.
Do not plant in heavy, poorly drained soils where winter waterlogging can rot the root system.

Common Questions

Kimi'idera Clematis questions

What zones can Kimi'idera Clematis grow in?

Kimi'idera Clematis is hardy in USDA Zones 4–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Kimi'idera Clematis deer resistant?

Not reliably. Deer may browse Kimi'idera Clematis, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does Kimi'idera Clematis bloom?

Kimi'idera Clematis typically blooms in spring through autumn. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Kimi'idera Clematis need full sun?

Kimi'idera Clematis does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
