Types of White Flowers to Grow
Illuminati Arch Mock Orange
Philadelphus coronarius, Zones 4 to 7
Truly a modern shrub, Illuminati Arch is much smaller than classic mock oranges, growing only about 4 feet tall, but it still has all the appeal. Its white blooms show up in late spring and offer fragrance through early summer. Prune immediately after ﬂowering, before next year’s buds form.

Lysimachia clethroides, Zones 3 to 9
A perennial that relishes full sun and moist soil, gooseneck loosestrife grows 1 to 3 feet in both height and width. Each 4- to 8-inch ﬂower spike curves downward like a goose’s neck, hence the name. The plant’s ﬂoral display wows from late spring through summer, then the foliage takes on seasonal yellow hues. Gooseneck loosestrife can be very aggressive, so be sure to take that into consideration when planting.
