Heuchera 'Fire Alarm' is a striking perennial plant, renowned for its vibrant foliage and year-round interest. Its leaves are a vivid, fiery red that intensifies in colour during cooler months, creating a stunning display in any garden. In spring and summer, the plant produces delicate, white to pale pink flowers on tall, slender stems, adding an additional layer of charm.

This hardy plant is evergreen in milder climates and thrives in partial shade, although it can tolerate full sun if kept well-watered. 'Fire Alarm' prefers well-drained, fertile soil and is relatively low-maintenance, making it ideal for both novice and experienced gardeners.

Its compact, mounding habit makes it perfect for borders, containers, and ground cover, providing a bold splash of colour throughout the year. Resistant to pests and diseases, Heuchera 'Fire Alarm' is a versatile and reliable choice for adding dramatic foliage to any garden setting.

Perfect as a groundcover, edger along paths, in shady shrub borders, under the trees and shrubs, or in pots and containers. Suitable for informal, cottage, woodland, and urban gardens.

Arundel Arboretum is a shrub and tree retail nursery with over 40 years of experience.

About Us

During this time, we have developed a large stock of trees, mature evergreen shrubs, conifers, Japanese maples, cedars and olives. What sets us apart from a generic garden center is solid unwavering focus on trees and some bigger shrubs. You will find thousands of trees, hundreds of varieties and lots of experts who are working on the nursery and more than willing to help you to choose a plant for you.

What you will not find is hot tubs, garden furniture and plastic garden gnomes. In a nutshell, trees is what we know and trees is what we do, and only trees (and some shrubs to go with the trees).
