Blooming from early summer into early autumn, it brings bold colour to shaded borders, landscape beds and large containers, and the flower heads can be cut for fresh or dried arrangements.\u003c\/p\u003e\n\n\u003ch3\u003ePlease Read Before Buying\u003c\/h3\u003e\n\u003cp\u003eHydrangea flower colour depends on your soil. Red and pink tones develop best in neutral to slightly alkaline soil; in acidic soil the same plants turn purple or blue. Plants grown from seed can also vary from the parent in flower colour and form. Hydrangeas are a long-term project from seed, and seedlings usually take two to three years to reach flowering size.\u003c\/p\u003e\n\n\u003ch3\u003eAt a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant type:\u003c\/strong\u003e Deciduous flowering shrub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlower colour:\u003c\/strong\u003e Red to deep pink in neutral to alkaline soil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBloom time:\u003c\/strong\u003e Early summer to early autumn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLife cycle:\u003c\/strong\u003e Perennial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature size:\u003c\/strong\u003e 3–5 ft (90–150 cm) tall and wide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacing:\u003c\/strong\u003e 3–5 ft (90–150 cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight:\u003c\/strong\u003e Partial shade; morning sun, afternoon shade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater:\u003c\/strong\u003e Moderate, consistent moisture\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardiness:\u003c\/strong\u003e USDA zones 5–9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime to flower:\u003c\/strong\u003e Usually 2–3 years from seed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer friendly:\u003c\/strong\u003e Yes, in large containers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeeds per packet:\u003c\/strong\u003e 100\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow to Sow\u003c\/h3\u003e\n\u003cp\u003eStart seeds indoors in spring, 8–10 weeks before the last frost. Hydrangea seeds are dust-fine, so sprinkle them on the surface of a moist, fine seed-starting mix and press gently without covering, as light helps germination. Cover the tray with a clear lid and keep it at around 65–75°F (18–24°C) in bright, indirect light; seedlings usually appear in 2–4 weeks. Grow them on in pots for their first year, then plant outdoors after the danger of frost has passed.\u003c\/p\u003e\n\n\u003ch3\u003eHow to Grow\u003c\/h3\u003e\n\u003cp\u003ePlant in partial shade, sheltered from hot afternoon sun and strong winds, in moist, well-drained soil rich in organic matter. For red and pink flowers, keep the soil neutral to slightly alkaline, for example by adding a little garden lime, and avoid acid (ericaceous) composts. Water regularly so the soil never dries out, and mulch to conserve moisture. Feed lightly in spring. Prune lightly just after flowering, as most flowers form on the previous year's stems.\u003c\/p\u003e","brand":"OrganicSeedsHub","offers":[{"title":"Default Title","offer_id":45534442225847,"sku":"SS-10-DEC126","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/3335\/6471\/files\/freepik__ultrarealistic-image-of-fully-mature-flowering-pla__51788.png?v=1766043226","url":"https:\/\/organicseedshub.com\/products\/red-hydrangea-seeds-hydrangea-macrophylla-bigleaf-hydrangea-flowering-shrub","provider":"OrganicSeedsHub","version":"1.0","type":"link"}
