- Deep crimson, penta-lobed deciduous leaves
- RHS Plants for Pollinators
Description
- A truly glorious ornamental tree with striking crimson foliage that will stand out in any garden
- Unlike some other Norway maple varieties, which are more spreading in their habit, 'Crimson Sentry' has a columnar crown and grows narrower than do other varieties
- The tree's broad leaves are a deep reddish purple, with each possessing five gently-serrated lobes. They offer a fantastic contrast to other predominantly green-leaved trees and foliage plants
- In the springtime, yellow flower corymbs appear, though they are very small and play second fiddle to the leaves - let's be honest, though, it would take a lot to outclass such fab foliage!
- Certified by the RHS as one of its Plants for Pollinators, this tree undoubtedly aids wildlife - bees are drawn to the springtime flowers, whilst birds love to snack on the tree's seeds (also known as samaras)

How To Grow
Good pest and disease resistance
Although acers have relatively few problems, you may still experience the odd issue or two with pests or disease. From the pest perspective, aphids can be a nuisance, though these are easily removed using a soapy water spray. In terms of disease, 'Crimson Sentry' can experience leaf scorch or Verticillium wilt.
Water well when establishing
This tree will benefit from regular watering (a weekly deep soak) during its first 12-24 months to help it establish, and particularly in drier spells. Once established, it will primarily only need watering in hotter weather. Signs your tree needs watering include drooping and wilting leaves.
Full sun to partial shade
Purple-leaved acer varieties like this one like sun (at least 6 hours or so every day) in cooler climates to help develop the best colour. When planted in hotter climates, though, the tree will appreciate some afternoon shade to protect it from scorching sunlight (somewhere that it receives morning sun and afternoon shade can be ideal).
Any fertile, moist, well-drained soil
Acers are tolerant of most soil conditions provided that there's good drainage. Consider amending your soil with some well-rotted manure or other organic matter just to improve its fertility.
Feed once annually
A once-yearly feed with all-purpose fertiliser (applied in February) can help give the tree a little extra growing boost, though it's by no means a must-do.

Best plants you will ever get online
I have ordered plants from them twice this year. They arrived well packaged, on time and looked strong and healthy. I feel the staff from Roots plants deal with their plants and customers with passion and care. I can’t wait to order again, price is good as well.

Satisfied customer
Unlike other online sellers, this company are well ahead in the quality stakes. My plant arrived promptly as per their promise and the plant was much more established and healthy than I had expected. It’s the second time I have ordered from them and I have faith in their promise. Excellent service.
