Plum Lite Sunflower (Helianthus annuus)
Plum Lite, part of the beloved ProCut series, brings a soft yet striking elegance to the cutting garden. Among the fastest to flower, this variety produces a generous flush of blooms in painterly blends of cream, dusty rose, and rich ruby-red, often with gentle bicolour patterns that shift as the petals unfurl.
While bred for its premium cut flower quality, Plum Lite also charms in the garden with its graceful branching habit, each side stem perfectly sized for hand-tied bouquets. Its rapid bloom cycle ensures an abundant harvest window, making it an exceptional choice for both market growers and home gardeners. Pairs beautifully with mauve cosmos, antique carnations, or pale apricot snapdragons for soft, romantic arrangements.

HOW TO GROW:
Direct Seed (recommended): Sunflowers are best grown from seed sown directly into the garden. Sow seeds after your last frost date, once the soil temperature is consistently above 18. Plant seeds 1/2-1" deep, spacing them 6–12" apart. Taller varieties should be spaced farther apart. Cover the seeds and water well. To protect seeds from birds and squirrels, you can cover the area with netting or a pot until the seedlings emerge.
Transplanting (alternative, use caution): Sunflowers form a deep taproot and are sensitive to root disturbance. If you choose to start them indoors for an earlier bloom, sow seeds into biodegradable pots (like peat or coir pots) 2–3 weeks before the last frost. Plant seeds 1/2-1" deep. Harden off seedlings for 7–10 days before transplanting the entire pot into the ground after all danger of frost has passed.
Pinching: Pinching is not recommended for single-stemmed, large-headed sunflower varieties, as it will prevent the formation of the main flower. For branching or multi-stemmed varieties, you can pinch the main stem when the plant is 12–18" tall to encourage lateral branching and more, albeit smaller, flowers.
Soil Preference and Watering: Sunflowers thrive in full sun and require well-drained, fertile soil. While establishing, they need consistent and deep watering. Water them deeply once a week, especially during dry periods and when the plants are forming buds. Once mature, they are relatively drought-tolerant but will perform best with regular watering.
Fertilizing: Sunflowers are heavy feeders and will benefit from fertile soil. If your soil is poor, you can amend it with compost before planting. An application of a balanced, all-purpose fertilizer can be given a few weeks after planting. Avoid high-nitrogen fertilizers, which can encourage leafy growth at the expense of flower heads.
Staking: Taller sunflower varieties may need staking, especially if they are in a windy location. Install stakes when the plants are young to avoid damaging the roots later.
Harvesting: For cut flowers, harvest in the morning just as the petals are beginning to unfurl. For sunflower seeds, wait until the back of the flower head turns brown and the petals have started to fall off. Cut the head from the stem and allow it to dry in a well-ventilated area for a few weeks before removing the seeds.
