Quick Guide

  • Compact red clematis flowering July through September

  • Reaches just 1-1.5m, ideal small spaces
  • Requires firm support and regular feeding
  • Free-flowering masses of vibrant red-purple blooms

Clematis 'Issey' is a compact, free-flowering deciduous climber producing masses of red flowers lightly tinted purple from early midsummer through late autumn. This Raymond J. Evison hybrid reaches just 1-1.5 metres in height, making it perfect for small gardens, patios, containers, and wall borders. Blooms emerge abundantly from July through September in full sun or partial shade. Plant in moist but well-drained soil with the base kept cool and shaded by other plants; plant the crown 5-8cm deep to encourage basal shoots from underground. This is a Pruning Group 3 clematis—the easiest option, requiring a hard prune in late February or March, cutting all stems back to 15-30cm above soil level. It is a greedy feeder and benefits from regular fertilization during the growing season. Provide firm framework support such as a trellis or obelisk to prevent wind damage. Hardy throughout the UK (H6), it tolerates chalk, clay, loam, and sandy soils equally well. Not pet-safe; keep away from dogs and cats.

Plant Guide

Plant in a sunny or partly shaded spot with the base kept cool and shaded. Ensure soil is moist but well-drained. Plant the crown 5-8cm deep to encourage basal shoots from underground. Support with a firm trellis or obelisk. In late February or March, cut back all stems to 15-30cm above soil level. Fertilize regularly during the growing season as this is a greedy feeder. Water consistently, especially in containers where moisture evaporates quickly. The plant flowers on new growth, producing continuous blooms from July through September.

Delivery Timeframes

We aim to deliver orders within 2–4 working days. During peak seasons, such as Christmas, delivery times may vary slightly due to increased demand. We will keep you informed at every stage.

Third-Party Couriers

For London postcodes outside a 5-mile radius of our Kentish Town garden centre, we may occasionally use a third-party courier for delivery. In these cases, we try our best to still deliver the items in the requested delivery time slot but please be aware that occasionally this may not always be possible and is out of our control.

Delivery Discrepancies

Please check your order as soon as it arrives. If there is any discrepancy — such as a missing, incorrect, or damaged item — please contact us within 48 hours of delivery so we can put things right. After this time, we will assume the order was received complete and in good condition. We are unable to take responsibility for damage that has occurred after this period.

Click & Collect

We encourage you to collect from our garden centre in Kentish Town — it saves on delivery costs and gives you the chance to see our full range of plants and products in person.

All Click & Collect orders must be collected within 7 days of being ready, unless a later date has been arranged with us in advance. If an order is not collected within this time, it will be cancelled and a refund issued.

Returns Policy

If you need to return an item, please contact us within 14 days of receipt to arrange a return or exchange. Products must be in their original condition and packaging. Plants may be non-refundable unless they arrive damaged or defective.

Items bought in-store or collected can be returned directly at the garden centre. If you would like us to collect a return and it is in good condition (e.g. you have changed your mind), it must be in its original condition, and the same delivery cost will apply for the return.

Plants marked as reduced for end-of-season clearance are non-refundable, as they are sold specifically to clear stock. This does not apply to special offers or multibuy promotions, which are eligible for returns as per our standard terms.
