  • Best in class for delphiniums
We've given our customers the chance to get their hands on some very new, very different delphiniums from the world-famous 'New Zealand Hybrids' programme. There are far too many hybrids produced for our supplier to sell, so we've grouped our favourites into an exclusive 'Breeders Mixture', aptly named 'Rising Stars'! This exciting mix of delphinium flowers blends picotees, pastels, singles, doubles and frosted hybrids for a spectacular, towering display. You can even cut some blooms for a striking flower arrangement indoors. Height: 120cm (47"). Spread: 75cm (30").

Flowering Months
Feed and water delphinium plants until they are fully established. The tall stems of delphinium flowers will require staking with stout canes. Canes should be put in place by mid spring to ensure that the plants are adequately supported throughout the growing season. Cut spikes of faded delphinium flowers back to a flowering sideshoot to encourage a second flush of blooms to be produced. In autumn, cut the old foliage back to ground level. Caution: Contact with delphinium foliage may irritate the skin and eyes. All parts are harmful if eaten.
Pot up delphinium plants using free-draining compost, and grow them on in frost free conditions until large enough to plant outside. Once they are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over 7 to 10 days before planting them outdoors. Choose a sunny position that is sheltered from strong winds, on moist, well drained soil. Protect young delphiniums from slugs and snails.
