Acer palmatum ‘Shaina’ – Shaina Japanese Maple

About Your New Acer palmatum ‘Shaina’ – Shaina Japanese Maple

Acer palmatum 'Shaina' is a dwarf deciduous Japanese maple with short internodes and a dense, rounded head. The small lobed leaves emerge bright red, deepen to maroon over summer and finish scarlet in autumn. Growth is tight and congested rather than open, which gives the plant its compact, cushion like outline.

Filtered light or morning sun gives the best leaf colour, with protection from harsh afternoon heat in warmer regions. Soil should be free draining and kept evenly moist. It adds only 15 to 40 centimetres a year and is frost tolerant once established, performing well through cool temperate and temperate zones.

Because it stays small, Shaina works in courtyards, narrow beds, rockeries and decorative pots where a full sized maple would crowd the space. It is often used in pairs flanking a doorway or a set of steps. For small gardens it gives the character of a Japanese maple at a manageable scale.

Frequently Asked Questions

About Shaina Japanese Maple

What is Acer palmatum 'Shaina'?

Shaina is a dwarf Japanese maple with short internodes and a dense rounded head. The small lobed leaves emerge bright red, deepen to maroon over summer and finish scarlet in autumn. It originated as a witches broom selection, which is what gives it the tight congested growth and compact outline.

How big does Shaina grow?

It is slow and small, reaching about 1.5 to 2.5 metres in height and 1.5 to 2 metres across after many years. Most plants stay near the lower end of that range in containers. This is one of the few Japanese maples that genuinely suits a courtyard bed without regular size control.

How fast does Shaina grow?

Very slowly, roughly 15 to 40 centimetres a year, and less in a pot or a dry position. That is deliberate, since the density and tight branching are what the cultivar is grown for. If you want immediate effect, start with an advanced plant rather than expecting quick growth from a small one.

Can Shaina be grown in a pot?

Yes, it is one of the better Japanese maples for containers because of its size and dense habit. Use a pot at least 400 millimetres across with a premium free draining mix, water consistently and shade the pot itself through summer. Refresh the top of the mix each spring and repot every few years.

Does Shaina need sun or shade?

Filtered light or morning sun gives the strongest leaf colour without burning. In warmer regions protect it from afternoon heat and from reflected warmth off walls and paving. Deep shade produces looser growth and duller foliage. The aim is bright light for part of the day with shelter through the hottest hours.

Is Shaina evergreen or deciduous?

Deciduous. It carries red to maroon foliage from spring through summer, colours scarlet in autumn, then drops its leaves for winter. The bare framework of congested twiggy growth is compact and holds its shape, so the plant still reads as a defined form in the garden through the dormant months.

How do I care for Shaina?

Keep the soil evenly moist and free draining, and mulch to keep the roots cool. Feed lightly in early spring, as heavy feeding pushes soft growth that spoils the compact habit. Pruning is seldom needed, though dead twigs can be cleared in late winter. Watch pots closely for drying out during hot spells.
