The Pacific Giant series was developed in California in the 1930s specifically to produce taller, larger-flowered, more spectacular delphiniums than the older European varieties — and 'Summer Skies' is the legendary sky-blue selection from that breeding programme. Tall, architectural flower spikes can reach 1.8m (six feet) in good conditions, completely covered with large semi-double flowers in clear azure with a contrasting white centre that gives each bloom a \"bee-eye\" quality. Hardy perennial flowering June and July, often with a second flush in late summer if cut back hard after first flowering. RHS Plants for Pollinators recognised — bumblebees particularly love delphinium spikes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eA note on growing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eDelphinium seeds need patience and the right conditions. Sow from January to April — surface-sow onto moist compost (delphinium seeds need light to germinate). Cover lightly with vermiculite to maintain humidity. Important: delphinium seeds germinate best at slightly cool temperatures (15–18°C) — high heat actually inhibits germination. A few weeks of cold treatment (refrigerator) before sowing can improve germination rates significantly. Germination takes 14–28 days.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePlant out into a sheltered, sunny or lightly-shaded position in deep, fertile, moisture-retentive but well-drained soil. Delphiniums are hungry plants — dig in plenty of compost or well-rotted manure before planting. The first year sees establishment; expect modest flowering. From year two onwards, the plants come into their full glory. \u003cstrong\u003eCritical growing tip\u003c\/strong\u003e: at 1.8m tall, 'Summer Skies' absolutely needs staking. Insert sturdy canes or grow-through plant supports early in the season — by the time the spikes are tall enough to need support, the plant is too fragile to stake without damage. After flowering, cut back hard to encourage a second flush. Slugs and snails are the main pest — protect young growth in spring.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e⚠️ \u003cstrong\u003eSafety note\u003c\/strong\u003e: All parts of Delphinium are toxic if ingested. Wear gloves when handling and keep away from grazing animals.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhere it shines\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAt the back of classic English cottage borders, where the towering blue spires define the quintessential cottage planting and provide vertical structure that few other plants can match. In wildlife gardens, where the deep nectar tubes are specifically valued by long-tongued bumblebees. As cut flowers for tall dramatic arrangements (handle with care — flower spikes are fragile after cutting). In any heritage planting scheme that wants traditional English country-garden character.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePlant alongside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe classic English cottage border combination: pair 'Summer Skies' with David Austin-style roses (if you grow them), Foxglove 'Excelsior Mixed' for matching vertical structure, and Aquilegia 'Barlow Mixed' for lower-level interest. For colour-coordinated cutting, combine with the lime-green spires of Bells of Ireland and the airy white of Ammi majus.\u003c\/p\u003e","brand":"Bishy Barnabees Cottage Garden Ltd","offers":[{"title":"Default Title","offer_id":57888034029942,"sku":"DEL-SSS","price":3.4,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/3566\/5206\/files\/Gemini_Generated_Image_9idbze9idbze9idb.png?v=1779020061","url":"https:\/\/www.summerwoodenplanters.com\/products\/delphinium-pacific-giant-summer-skies","provider":"Summer Wooden Planters","version":"1.0","type":"link"}
