💜 Pale blue-mauve flowers 6–8 cm from June to September • 🔄 Abundant flowering on the current year's wood — simple pruning • ☀️ Sun to partial shade • ❄️ Hardy down to –20 °C • 📏 H65 cm | Pot Ø15 cm
Clematis 'Justa', or compact lilac clematis, is a deciduous climbing hybrid of the Viticella group, from a horticultural selection in Europe (Lithuania). Its pale blue-mauve flowers, 6 to 8 cm across, with slightly wavy sepals and pale yellow anthers, bloom en masse from June to September on the current year's shoots. Among the clematis in the clematis collection, it is the most compact variety and best suited for small spaces.
Easy to prune (group 3, cut back hard in February), vigorous and undemanding, it does equally well in a large container or in the ground and adapts to every exposure on a balcony or terrace.
Which clematis should you choose?
Verdeia's clematis collection offers many varieties with distinct colors and blooming periods. Here is how to place 'Justa' among the other plants in the catalog:
- Clematis 'Justa' (this plant) — pale blue-mauve flowers 6–8 cm, group 3, blooming June–September, very compact habit (max 2 m). The smallest variety and the best suited to pots and small spaces.
- Clematis 'The President' — large intense violet flowers 15 cm, repeat-flowering June–September. The choice for a deeper color and much larger flowers on a pergola.
- Clematis 'Niobe' — large velvet red flowers 12–15 cm, repeat-flowering May–September. The choice for a spectacular blue-mauve and red contrast on the same support.
- Clematis 'Miss Bateman' — large satin white flowers 12–15 cm, two waves in May-June and August-September. The choice for a very bright blue-mauve and white duo with complementary blooming.
Light & location
'Justa' is one of the most tolerant clematis — it blooms equally well in full sun or bright partial shade. Its very compact habit (up to 2 m) makes it especially suitable for small containers and limited supports. Its petioles coil by themselves around any thin support.
- Exposure: full sun or partial shade — the blue-mauve colors are more intense and long-lasting in light shade.
- Support: small trellis, wire mesh, arch, or railing — its compact habit suits light structures.
- Soil: fertile, cool, and well-drained — base in shade or mulched.
- In pots: large container of at least 25 cm — one of the clematis best suited to container growing.
Protect the roots with mulch or a low perennial at the base — root coolness is the main condition for abundant and continuous flowering from June to September.
Watering & care
'Justa' belongs to group 3 — it blooms only on the current year's shoots. Its pruning is the simplest of all: a hard cut back to 30–50 cm above the ground every February. In pots, the finger test helps gauge watering safely. If the foliage yellows during the season, the usual causes are overly dry soil or depleted substrate in pots.
- Watering: regular, keep substrate cool but never waterlogged.
- Pruning: cut back hard to 30–50 cm above the ground in February — all stems, every year without exception.
- Fertilizer: rich in potassium in spring to support the long summer bloom.
- Mulching: 10 cm at the base to keep the roots cool and reduce watering.
The harder you prune in February, the more vigorously 'Justa' regrows with many flower-covered stems from the base — an unpruned plant ends up flowering only at the top with a bare base.
Decor ideas & plant pairings
The soft and bright blue-mauve of 'Justa' creates subtle and romantic harmonies — in a Mediterranean garden as well as on a flowering jungle terrace, its small delicate flowers naturally complement larger blooms and contrasting foliage.
- For a spectacular blue and red duo on a trellis, pair it with the velvet red Clematis 'Niobe' on the same support — the small blue-mauve flowers of 'Justa' and the large deep red flowers of 'Niobe' bloom simultaneously from June to September, creating a lively warm/cool contrast.
- For an evergreen backdrop that enhances the blue flowers, plant it in front of an evergreen Lonicera henryi — the shiny dark green honeysuckle foliage creates a natural frame that intensifies the brightness of the blue-mauve throughout the season.
- For a composition on a partially shaded balcony, pair it with Passiflora caerulea on the same support — the two blue blooms complement each other with radically different flower structures (small and simple vs. large and graphic) for a very rich effect.
- To enhance the blue-mauve in a pot, a terracotta or ochre ceramic container creates a warm resonance that intensifies the coolness of the blue-mauve flowers by contrast and adds depth to the arrangement.
At the end of flowering, the silvery feathery fruits of 'Justa' persist on the stems for several weeks — their decorative lightness extends the plant's interest until the winter pruning in February.
Verdeia tips
- Cut back hard every February without exception: 'Justa' belongs to group 3 and blooms on the current year's shoots — pruning to 30–50 cm above the ground each winter is essential for dense flowering from the base, not just high up on a bare stem.
- Train the stems on the support from March: the new spring shoots are fragile and easily tangle — guide each stem onto the trellis as soon as it reaches 20 cm to ensure even coverage and avoid the impossible-to-untangle mess in May.
- Water more frequently in pots than in the ground: in large containers, the substrate dries out much faster than in the ground during midsummer — watering every two days in hot weather is often necessary to maintain the abundant flowering typical of this variety.

What should I do when my plant arrives?
Open your package as soon as you receive it and carefully remove the plant from its packaging. Let it acclimate for 24 hours in its new environment before watering. If it has been slightly stressed during transport, it will recover its shape after one or two days in the light.
What should I do if my plant arrives damaged?
Contact us within 48 hours with a photo of the issue. Our team will assess the situation and offer you the best solution: replacement, partial refund, or recovery advice.
