Judas Tree
Cercis siliquastrum
- One of the earliest trees to flower in spring, Cercis bursts into colour in April and keeps its large clusters of spectacular bright pink blooms right throughout May.Â
- The flowers are said to look like hummingbirds, with showy blooms tapering off into long, thin beak-like stems
- They're set amongst bright green, heart-shaped foliage that turns a gorgeous range of golden yellow and bronze tones in the autumn
- Cercis are fully hardy trees, happy in both full sun and partial shade, and will tolerate most soil types. Slow growing and compact, they're perfect for even small gardens
- Clusters of reddish purple flattened seed pods hang from the branches in autumn
- One of the few trees to grow flowers from its trunk, in a natural phenomenon known as cauliflory
- Holds the RHS Plants for Pollinators award for its value to bees, butterflies and other insects
- A low maintenance tree that's drought tolerant once established
- Our trees are professionally pruned before dispatching.

Will this grow in my garden?
Can I grow this in a pot?
Yes, Judas Tree can be grown in a pot initially. Start with a 50cm pot. Depending on its vigour, it may need moving to the ground after a few years. Ensure adequate drainage and water regularly during warm weather above 20°C.
How big does it get?
The Judas Tree typically reaches a height of 6 to 8 metres, with a spread of 6 to 8 metres, although it can be maintained at a smaller size with regular pruning.
How much sunlight does this need?
Judas Tree prefers full sun to partial shade, requiring at least 4 to 6 hours of direct sunlight daily to thrive.
What kind of soil does this plant prefer?
Judas Tree prefers well-drained, moderately fertile soil, but is quite adaptable to most soil types including clay, loam, and chalk. It tolerates winter ground temperatures down to -10°C. Plant in a hole at least 50cm wide for best results.
How much watering does this plant need?
Judas Tree requires regular watering, especially during its first few years of establishment. Provide approximately 10 to 20 litres of water per week, ensuring the soil remains moist but well-drained. During hot weather above 25°C, increase watering frequency to prevent the roots from drying out.
Will this plant need pruning?
Judas Tree should be pruned immediately after flowering in late spring, removing up to 30cm of old growth.
How hardy is this plant?
Cercis siliquastrum has an RHS hardiness rating of H5, making it hardy down to -15°C in most of the UK, but it may require a sheltered position in colder northern areas.
