Gardeners' Notes:

Last week I planted three small Snow Sport yarrows in my front yard, which faces east, and gets approx 5 hours of sun each day and quite dry in our Arkansas summers. Companion plants (already established) are Zagreb Coropsis and Butterfly Weed and common ajuga. After reading some other entries to the effect that any of the millefolium group are horribly agressive, I am having second thoughts. I do not mind deadheading and dividing or ripping out handfuls if necessary from time to time, but do not want to plant something as aggressive as Kudzu... if ya know what I mean.

Short 16" - Plant 14" apart. Z3-9. The very best sparkling white Milfoil. Heavily flowers in the summer with deep green fern-like foliage. Flowers from summer to early fall. Butterflies love it. Excellent fresh cut flowers or dried. Tolerant of drought, wind and heat. Grows well in almost any soil type. Spreads to fill in, so give them room.

My plant is now a year old, has grown to cover a 3' square section of a dry slope, and is quite striking both in the garden and vase. In fact, I have found that this particular cultivar makes an excellent substitute for baby's breath in cut flower arrangements.
