The planting guide said to plant the bulbs 8 inches deep. I cavalierly ignored those instructions and planted the bulbs about 4 inches deep. By summer, the stems were flopping about. Last fall, after cutting back the stems I replanted the bulbs at the proper depth. I’m hoping this prevents the need for staking. I generally dislike propping up plants as it looks unnatural and rigid.
Last year my plant bloomed from July 10 to July 28.
From White Flower Farm. I have 6 bulbs planted in a circle about a foot in diameter. I think the spacing is too tight, and maybe 18-24 inches diameter would have looked less clustered. Still, this is a striking plant in bloom. The stems are incredibly sturdy and don’t require staking.
Last year, ‘White Elegance’ bloomed in my garden from July 10 to July 25.
