Description
The Seeds of Clarkia unguiculata 'Albatross' allow you to easily grow this floriferous annual plant, ideal for brightening up late spring borders with its elegant double white flowers with delicately ruffled petals. Its upright and flexible habit makes it an excellent companion for borders or a naturalistic setting. It is distinguished by its reddish stems, finely lanceolate foliage, and flower spikes laden with buds that bloom progressively. Very easy to grow, it prefers well-drained, moderately fertile, rather cool and light soil, and sunny exposures. Not very hardy, it is intolerant of frosts and must be sown directly in situ in spring, or in autumn in mild climates.
The Clarkia unguiculata 'Albatross' has the botanical synonyms Oenothera elegans Albatross and Clarkia elegans Albatross. It is an annual plant from the Onagraceae family also known as Elegant Clarkia 'Albatross'. Native to California, the species type is endemic to the wooded areas and dry slopes of that State, where it thrives in well-drained soil and sunny conditions. The 'Albatross' cultivar is distinguished by its pure white double flowers contrasting with the pink or purple hues of the type species. This plant has an upright and slender habit, typically reaching a height of 30 to 45 cm in cultivation, with a spread of about 30 cm. Its growth is rapid, completing its life cycle in a single season. The stems are thin, sometimes slightly reddish, and bear green, deciduous, lanceolate leaves measuring 2 to 5 cm long. The flowers are formed of four white, often double petals and measure about 2 to 3 cm in diameter. Flowering extends from late spring to summer depending on the sowing date, which should be staggered to enjoy a long flowering period, attracting pollinators such as bees. The Clarkia unguiculata is appreciated for its ability to self-seed naturally, ensuring a continuous presence in suitable gardens.
The Clarkia unguiculata 'Albatross' adds a touch of lightness and elegance to summer borders. Its white flowers sway gracefully atop slender stems, creating a subtle movement with the slightest breeze. To accentuate this delicacy, it harmonises beautifully with Nigella damascena 'Miss Jekyll', offering a soft contrast with its airy blue flowers, while the Papaver rhoeas 'Thai Silk Rose Chiffon' adds touches of pink and red, enriching the colour palette. In pots or in the ground, these combinations create poetic displays ideal for cottage-style gardens or sunny borders.

Planting and care
Sowing:
Sow Clarkia Albatross seeds from March to May, directly in their final position.
Sow thinly, burying the seeds 3mm deep, spacing them 45cm apart in furrows dug into well-prepared and well-loosened soil. Thin the sowing, leaving a space of 15 to 22cm between each seedling.
For earlier flowering, you can sow indoors in pots or trays.
Transplant when the young plants are large enough to handle, into 8cm pots or trays. Enable them to grow in full light, watering sparingly. Plant out outdoors when all risk of frosts has passed.
Growing:
Easy to grow in sun in any temperate climate, clarkias appreciate a slightly acidic, neutral or slightly calcareous, moist but well-drained soil enriched with sand and compost, . Allow the soil to dry out a little between waterings. Over-rich soil encourages foliage growth at the expense of flowering. Removing faded flowers will prolong the flowering period.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
