Gomphrena ‘Las Vegas White’

Trial: Annual

Year Trialed: 2009

Good Qualities:

Pure white color (2); Prolific flowering (2); No pest or disease problems; No browning; Long lasting in the field, easy to cut in clumps; Best of the Las Vegas series, cannot see white flowers coming out from flower heads because flower head is white; Color mixed well with many other flowers for bouquets, nice accent, germination was good.


Too short (3); Not so short it made it unusable; Flower heads small, weak and floppy, especially later in the season; about 10 days later than other Las Vegas lines to start flowering; None; Difficult to see where to cut to keep new growth coming, was affected by disease more significantly than gomphrena ‘Audray Pink’ and ‘Purple Red’; Not a problem, but I think the stems were so full that when I tried to cut them they easily got tangled up; Was so much shorter than my regular QIS purple and pink gomphrena that I did not bother to cut it, stem length was 6 to 8 inches.

Similar Cultivars:

Gomphrena ‘Las Vegas Pink’ and ‘Las Vegas Purple’, different color but reacted to disease the same and had same growing habit; Growing the same as other gomphrenas.


It got about half the height of the Audrey series for us, the colors were nice but the taller gomphrena varieties are easier to harvest; All the stems were the same height; During trial, contracted a bacteria (was never officially diagnosed), this was determined because the plants that were cut were much worse than the ones that were not cut, thought to have been transferred through pruners that had not been disinfected between cuts, the leaves curled and turned red and brown on the edges, stems and leaves also turned crispy, my hands felt powdery after I cut them which came from the stems and leaves, however, this did not affect the flowers, the flowers still looked good, the color was only a little washed out, and the plant still kept the same average number of stems per plant, after not cutting for 3 weeks, leaves and stems look much better, to where it’s hardly noticeable, affected vase life by 2 days; I liked the flower for its color and the plant grew very nicely, it was full and had many blossoms per stem each week; Cornell trial yield: 9 stems in field, 14 in tunnel; Length: 18 inches in field, 22 inches in tunnel, would be a great container plant!


None; Cool water, Floralife, cool after cutting and don’t leave in heat of the field; Water; Postharvest life “forever”.
