Ceanothus 'Trewithen Blue' is a fantastic evergreen tree with profuse, dark-blue summer flowers emerging in clusters from April through to June. Ceanothus, also known as Californian Lilac, are very popular with bees and other pollinating insects, due to the masses of flowers that cover them.
It can be grown as a climbing shrub, but we have trained it in a single stem form to create a wonderful small tree reaching about 3m in height. Note you can still train it against a wall as a climber, fan or espalier if you wish.
Ceanothus 'Trewithen Blue' is great for your round interest, with its profuse blue flowers and evergreen foliage that provides a great, dark-green foil for other neighbouring plants. Ceanothus require a well drained soil a sunny situation, that is not exposed to drying winds.
AKA Californian lilac, Ceanothus arboreus 'Trewithen Blue'
Our pot grown Californian Lilac trees can be planted at any time of the year. Start by removing weeds and grass within a metre of your desired planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help the tree establish more effectively, sprinkle root grow in the hole.
Remove the pot, gently loosen the roots and place into the planting hole. Mix 50% of the original soil with 50% compost, fill in the hole and firm around gently. Avoid banking the soil up around the collar of the tree. We recommend planting Ceanothus trees with a stake and tie - instructions are in the planting guide.
If you’re planting Ceanothus in spring or summer, water well for the first few months. Increase watering if there are extended periods of hot or dry weather. If planting in autumn, you may only need to water a little. Irrigation kits make it easier.
Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons. If your area is prone to rabbits, use a rabbit guard.
Ceanothus trees do not require a lot of pruning. Simply remove any dead, diseased or awkwardly placed branches from the tree as and when you see them.

Below are definitions of various forms, which refer to the shape of the tree defined by the pruning it has received. For more advice, please contact us.
Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.
Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.
Multi Stem: A multi stem tree is has two or more stems arising from or near ground level, growing from one root system. Take care to buy a true multi-stem like all ours and not those that are 3 saplings in a pot to cheaply imitate them.
Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.
Bush: A plant with many stems low down, rather than one clear stem.
Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.
Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branch), which supports a branched crown. Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height.
Standard either 6-10cm or 8-10cm girth, approximately 2.5-3.0m in height
Premium Standard 10-12cm girth, approximately 3.0-3.5m in height
Heavy Standard 12-14cm girth, approximately 3.5-4.5m in height
Extra Heavy Standard 14-16cm girth approximately 4.0-6m in height
