Description
Growing x Petchoa 'Caliburst Yellow' from seed allows you to grow this remarkable hybrid plant at a lower cost, born from the cross-breeding between a petunia and a calibrachoa, offering vibrant and long-lasting flowering. Its spreading and slightly trailing habit, combined with its large bright yellow flowers with a golden centre, make it an ideal choice to brighten up planters, hanging baskets and flower beds. This tender perennial is usually grown as an annual and appreciates a sunny or lightly shaded position and well-drained, fertile and moist soil. It tolerates summer heat, but dislikes excess stagnant moisture or temperatures below -5°C. Very floriferous and easy to grow, it is a useful plant for long-lasting summer decoration.
x Petchoa ‘Caliburst Yellow’ is an intergeneric hybrid resulting from the cross-breeding between Petunia and Calibrachoa, belonging to the Solanaceae family. The Petunia genus includes 35 species of herbaceous, perennial or annual plants, native to the tropical regions of South America and particularly Brazil. Calibrachoas are tender perennial plants often grown as annuals. Very similar to petunias, they differ in the number of chromosomes that make up their genetic heritage and some morphological characteristics; their flowers are smaller, their vegetation is shrub-like or herbaceous with woody stems, their development is less significant, and they tolerate drought better. The cultivar ‘Caliburst Yellow’, developed by PanAmerican Seed under the code name ‘PAS1553948’, is the first Petchoa available from seed, combining the generous flowering of calibrachoas with the robustness of petunias. It is also known under the names Petunia × Calibrachoa Hybrid, Caliburst™ series or Petchoa × hybrida Caliburst™ Yellow. Its habit is both rounded and spreading, reaching a height of 15 to 25 cm and a width of 50 to 70 cm. Growth is rapid, with flowering beginning approximately 77 to 91 days after sowing. The 5 to 7.5 cm diameter flowers are bright yellow and slightly undulate. Flowering extends from spring to autumn. The non-sticky leaves are medium green, and the stems are flexible and branching. The root system is fibrous, adapted to well-drained soils.
In a container, Petchoa 'Caliburst Yellow' acts like a burst of sunshine, illuminating terraces and balconies. Its flexible and carpeting habit lends itself to combinations, mixed with the blue spikes of Salvia farinacea 'Victoria Blue', the purple foliage of Ipomoea batatas 'Sweet Caroline Purple' and the orange tones of Bidens 'Beedance Painted Red'. In gardens, it is a joyful plant to fully enjoy from May until the first chills.

Planting and care
To successfully sow Petchoa 'Caliburst Yellow', sow the seeds indoors 7 to 8 weeks before the intended outdoor planting date, approximately 7 to 10 days after the last frost.
Sow them on the surface of moist compost, without covering, as light promotes germination. Maintain a constant temperature of 20 to 25 °C in a bright environment. Germination typically occurs within 7 to 14 days.
Once the seedlings reach about 5 cm in height, prick them out individually. Pinch out the young plants when they have three true leaves to encourage branching. Before transplanting outdoors, gradually acclimatise the plants to outdoor conditions. Plant them in the ground or in pots after all risk of frost has passed, spacing them 25 to 38 cm apart.
Petchoa 'Caliburst Yellow' prefers a position in full sun or partial shade and fertile, moist, well-drained soil. It is important to keep the compost moist without excess water to avoid root rot.

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).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
