Lobelia ‘White Palace’ is a low-growing, dense annual summer flower distinguished by its pure white, small blossoms. The plant reaches a height of only 10–15 centimeters, making it a practical choice for landscaping borders, rock gardens, and various garden and balcony containers. This variety blooms profusely from spring until the first autumn frosts, provided the plant receives sufficient moisture and regular fertilization. A particular advantage for the gardener is the granulated form of the seeds – each granule contains 5–7 seeds. This solution eliminates the tedious task of subsequent pricking out and immediately ensures the growth of a vigorous and dense plant cluster.
Usage and Cultivation Instructions:
-
Sowing Time: February to March (indoor pre-cultivation).
-
Sowing Depth: Do not cover seeds with soil; gently press them onto the surface of moist substrate (light germinator).
-
Growing Location: Prefers a semi-shady to shady location, protected from direct and harsh midday sun.
-
Outdoor Planting: Transplant outdoors into beds or outdoor pots only in late May or early June, once the risk of night frost has completely passed. The spacing between plants in the bed should be approximately 15 cm.
Tips and Recommendations:
-
Cover the seed tray with plastic film or glass to maintain the uniform moisture required for germination, but ventilate the container daily to prevent mold.
-
To promote and extend flowering, regularly add liquid fertilizer for flowering plants during summer watering.
