Known for its uniform growth, vigorous flowering, and large central clusters of star-shaped flowers, it’s a beautiful addition to any floral arrangement. This series blooms in both spring and autumn, and in milder climates, it can be produced almost year-round, making it an ideal choice for seasonal transitions in gardens and floral productions.\u003c\/p\u003e\n\u003ch3 data-start=\"566\" data-end=\"587\"\u003e\u003cstrong data-start=\"570\" data-end=\"587\"\u003eKey Features:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"588\" data-end=\"1160\"\u003e\n\u003cli data-start=\"588\" data-end=\"719\"\u003e\n\u003cstrong data-start=\"590\" data-end=\"621\"\u003eVibrant Violet-Blue Blooms:\u003c\/strong\u003e Large, eye-catching central clusters of star-shaped flowers, surrounded by smaller side umbels.\u003c\/li\u003e\n\u003cli data-start=\"720\" data-end=\"803\"\u003e\n\u003cstrong data-start=\"722\" data-end=\"741\"\u003eEarly Blooming:\u003c\/strong\u003e Flowers earlier than other varieties in the Supreme series.\u003c\/li\u003e\n\u003cli data-start=\"804\" data-end=\"900\"\u003e\n\u003cstrong data-start=\"806\" data-end=\"825\"\u003eUniform Growth:\u003c\/strong\u003e A uniform, vigorous variety perfect for cut flowers and garden displays.\u003c\/li\u003e\n\u003cli data-start=\"901\" data-end=\"1034\"\u003e\n\u003cstrong data-start=\"903\" data-end=\"928\"\u003eSeasonal Flexibility:\u003c\/strong\u003e Blooms reliably in both spring and autumn, adaptable for almost year-round production in mild climates.\u003c\/li\u003e\n\u003cli data-start=\"1035\" data-end=\"1160\"\u003e\n\u003cstrong data-start=\"1037\" data-end=\"1051\"\u003eVersatile:\u003c\/strong\u003e Excellent for filling seasonal gaps, making it a stable factor for transitional periods in floral designs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-end=\"2733\" data-start=\"2706\"\u003e\u003cstrong data-end=\"2733\" data-start=\"2710\"\u003eAdditional Details:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-end=\"2987\" data-start=\"2734\"\u003e\n\u003cli data-end=\"2782\" data-start=\"2734\"\u003e\n\u003cstrong data-end=\"2757\" data-start=\"2736\"\u003eLight Preference:\u003c\/strong\u003e Full sun to part shade\u003c\/li\u003e\n\u003cli data-end=\"2813\" data-start=\"2783\"\u003e\n\u003cstrong data-end=\"2802\" data-start=\"2785\"\u003ePlant Height:\u003c\/strong\u003e 75-90 cm\u003c\/li\u003e\n\u003cli data-end=\"2843\" data-start=\"2814\"\u003e\n\u003cstrong data-end=\"2832\" data-start=\"2816\"\u003eStem Length:\u003c\/strong\u003e 75-90 cm\u003c\/li\u003e\n\u003cli data-end=\"2898\" data-start=\"2844\"\u003e\n\u003cstrong data-end=\"2866\" data-start=\"2846\"\u003eHardiness Zones:\u003c\/strong\u003e 5-9 (Annual in most climates)\u003c\/li\u003e\n\u003cli data-end=\"2987\" data-start=\"2899\"\u003e\n\u003cstrong data-end=\"2923\" data-start=\"2901\"\u003eSoil Requirements:\u003c\/strong\u003e Well-drained, fertile soil with neutral to slightly acidic pH\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"1162\" data-end=\"1190\"\u003e\u003cstrong data-start=\"1166\" data-end=\"1190\"\u003eGrowing Information:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"1191\" data-end=\"1569\"\u003e\n\u003cli data-start=\"1191\" data-end=\"1238\"\u003e\n\u003cstrong data-start=\"1193\" data-end=\"1213\"\u003eScientific Name:\u003c\/strong\u003e \u003cem data-start=\"1214\" data-end=\"1236\"\u003eTrachelium caeruleum\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1239\" data-end=\"1279\"\u003e\n\u003cstrong data-start=\"1241\" data-end=\"1266\"\u003eCultivation Location:\u003c\/strong\u003e Greenhouse\u003c\/li\u003e\n\u003cli data-start=\"1280\" data-end=\"1322\"\u003e\n\u003cstrong data-start=\"1282\" data-end=\"1300\"\u003ePlant Density:\u003c\/strong\u003e 24-86 plants per m²\u003c\/li\u003e\n\u003cli data-start=\"1323\" data-end=\"1394\"\u003e\n\u003cstrong data-start=\"1325\" data-end=\"1343\"\u003eSowing Period:\u003c\/strong\u003e Midwinter to early spring, late summer to autumn\u003c\/li\u003e\n\u003cli data-start=\"1395\" data-end=\"1440\"\u003e\n\u003cstrong data-start=\"1397\" data-end=\"1425\"\u003eCultivation Temperature:\u003c\/strong\u003e Cool to warm\u003c\/li\u003e\n\u003cli data-start=\"1441\" data-end=\"1480\"\u003e\n\u003cstrong data-start=\"1443\" data-end=\"1467\"\u003eTime to Young Plant:\u003c\/strong\u003e 8-12 weeks\u003c\/li\u003e\n\u003cli data-start=\"1481\" data-end=\"1518\"\u003e\n\u003cstrong data-start=\"1483\" data-end=\"1504\"\u003eTime to Maturity:\u003c\/strong\u003e 17-27 weeks\u003c\/li\u003e\n\u003cli data-start=\"1519\" data-end=\"1569\"\u003e\n\u003cstrong data-start=\"1521\" data-end=\"1545\"\u003eDays to Germination:\u003c\/strong\u003e 10-14 days at 18-22°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"1571\" data-end=\"1600\"\u003e\u003cstrong data-start=\"1575\" data-end=\"1600\"\u003eSowing \u0026amp;
