'Otto's Thrill,' thrills and spills as an eye-catching dinnerplate dahlia, adorned with enormous and magnificent blooms in a luminous shade of pink. The fully double flowers are exceptional cut flowers, effortlessly brightening up vase arrangements with their captivating blooms. Its colossal flowers, each an impressive 23cm (9in) in diameter, make a striking statement, and the well-deserved RHS Award of Garden Merit recognition attests to its exceptional qualities.

How to care for Dahlia Otto's Thrill:

Dahlia tubers can be planted outside after frost, or started off in pots under glass in late winter to early spring. Plant them horizontally approximately 12cm deep, making sure the ‘eyes’ are uppermost. Allow enough room between each tuber so the plants can grow and spread to their full size without being over-crowded. While in growth, provide a high-nitrogen liquid feed each week in June, then a high-potash fertiliser each week from July to September. Stake with canes or brushwood if it becomes necessary. In mild areas, leave them in situ over winter, but protect the crown with a generous layer of dry mulch. In colder areas, carefully lift and clean the tubers once the first frosts have blackened the foliage and allow them to dry naturally indoors. Then place the dry tubers in a shallow tray, just covered with slightly moist potting compost, sand or vermiculite and store in a frost-free place until planting out again.
