One of the very best dwarf sunflowers mixture available, these 3 foot plants produce pollen-free 4 inch(14cm) blooms in colors ranging from white bicolor (often highlighted with red) through to pale yellows. Massed in the garden they look like a watercolor come to life. Sunflowers are impressive both in the field and in a vase and the seeds make for pleasant eating; at least the birds think so! Pollen free types are excellent for cut flowers; they are uniform and vigorous in growth even under low temperature and short day conditions. Dense planting will provide quality cut flowers. These varieties can be sown from September to March under glass and from April to August outdoors. The Pastel Babies like a minimum night temperature of 8øC, with a maximum temperature of 25øC during the day. They require little or no fertilizer and water sparingly. Hardiness zones: All. The operative word here is sun. Like its name the sunflower needs plenty of direct sun; a minimum of 6hrs a day to grow healthy plants. If you plant sunflowers out of direct sun light they will stretch for the sun. They will become so spindly stretching for the sun eventually they will fall to the ground. We recommend full sun for the better part of the day to grow strong healthy sunflowers. To promote deep roots and strong stems, water deeply but infrequently. One to two cups of a complete fertilizer per 10 row feet in the spring is adequate for the year. Over fertilization may cause stems to break in the fall. The Helianthus Pastel Babies likes a well-drained soil.
