General Culture:
Easily grown in dry to medium wet, well-drained soil in full sun. Thrives in poor, sandy or rocky soils with good drainage. Tolerant of heat, humidity and drought. Prompt deadheading of spent flower stalks encourages additional bloom. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. 'Zagreb' can spread in the garden by rhizomes and self-seeding, particularly in moist fertile soils.
Noteworthy Characteristics:
'Zagreb' is a compact form (to 2' tall) and features pale yellow, daisy-like flowers (1-2" diameter)
Shearing plants in mid-summer (early August) when bloom usually tapers down will encourage a fall rebloom.
No serious insect or disease problems. Tends to sprawl, particularly if grown in moist and/or fertile soils. Crown rot may occur if grown in moist, poorly drained soils
Borders. Also effective in naturalized areas or cottage gardens. Good plant for areas with poor, dry soils.
