Comment

"A straight forward, pure white variety. Flowers mid season. Height 125cm (50”)" from R. V. Roger.

This giant-flowered gladiolus is used in the back of borders, displays in hotels and churches as well as in exhibitions. Excellent Cutflower and bedding plant.

In temperate zones, the corms of most species and hybrids should be lifted 4-6 weeks after flowering and stored over winter in a well-ventilated, warm place where the temperature is in 50 degrees Fahrenheit range, then replanted after the deciduous trees are well into leaf in April. Set corms at 6 inches deep and 6 inches apart.
Can be planted anytime of the year as long as frost is not likely, allowing several crops or seasons of flowers to be had by successive plantings. Flower in about 80-90 days.
Some species from Europe and high altitudes in Africa, as well as the small 'Nanus' hybrids, are much hardier (to at least -15°F/-26°C) and can be left in the ground in regions with sufficiently dry winters.
Plants are propagated either from small cormlets produced as offsets by the parent corms, or from seed; in either case, they take several years to get to flowering size.
Clumps should be dug up and divided every few years to keep them vigorous.

Striking accent plant among summer-flowering annuals and usefull addition to perennial borders. Very good container plants, but take care when selecting container as plants can become quite top heavy when in full bloom. Cut flowers will last long time in floral arrangements; cut as soon as first buds show colour with own foliage acting as complement to flowers. Cut or remove the flower stalk just below the first leaf so the remaining foliage can replenish the corm for next season’s blooms.
