Q How far apart should Penny's Worth be planted ?
A About 8 inches apart (7-9 inches), with some irregularity, will make a pleasant appearance, and
will cover the ground well. Or, for a formal appearance, measure the ground into 8-inch
criss-crossing rows, and plant in straight lines. The number of plants required will be the same
in either case.
Q How many Penny's Worth will I need ?
A You will need 2¼ plants per square foot of planting area. Measure and calculate the square footage,
subtracting any areas which may have other kinds of plants. As an example, you might have a
bed 4 X 10 feet, or 40 square feet. One clump of Iris in the bed occupies about 9 square feet,
leaving 31 square feet for Penny's Worth Ground Cover. You will need 31 X 2¼, or 70, Penny's Worth plants.
Q When is the best time to plant Penny's Worth Ground Cover ?
A There is no preferred time. But fall plantings in frost-prone regions will need to be mulched
for good winter survival.
Q Are Penny's Worth Ground Cover plantings Guaranteed ?
A Yes. All our Daylily plants are Fully Guaranteed.
Q When will it look like a good Ground Cover ?
A Growth will occur mainly in the warm summer months.
During the first summer of this growth you will have an attractive Ground Cover with
quite a lot of bloom. During the second summer you will
have a dense cover of foliage, and heavy bloom.
Q Do I have to weed the Ground Cover ?
A Yes. For several months following planting you should prevent fast-growing weeds from overtaking the
Penny's Worth plants. Frequent light cultivation is often much easier than waiting for the weeds to become large
and troublesome. During the second summer of growth you may need to weed only 3-4 times.
During the third summer, the dense foliage will suppress most weeds, and a single weeding may
Q Should I mulch the planting ?
A Maybe. Fall plantings in frost-prone regions must be mulched for good winter survival.
Also, spring and summer plantings will often benefit from a mulch, first to suppress many kinds
of weed growth, and second to retain soil moisture. However, if you find that your local
weeds come right up through your choice of mulch, then you may discover that weed control
is easier without any mulch.
Q Do I have to divide the Penny's Worth plants ?
A No. The clumps will grow larger and denser year by year, until the Ground Cover becomes
a solid mat.
Q When does Penny's Worth bloom ?
A Here in Connecticut (Zone 5), from late June to late August. In warmer regions, it will
begin sooner and continue for about 5-8 weeks. (Early, Early Midseason, Midseason,
Q How high does Penny's Worth Ground Cover grow ?
A The foliage is from 6 to 10 inches high, depending upon soil and sunlight. The flowers are about 12-14 inches.
Q What if I make the bed bigger 2-3 years from now ?
A You will need some additional Penny's Worth plants. You can either purchase more plants, or you
can dig some of the plants in your original planting, dividing them into as many as you
need for the extended bed.
Q How winter hardy is Penny's Worth ?
A It is fully winter hardy, surviving in Quebec, northern Minnesota, and Anchorage, Alaska.
Q Will my Penny's Worth Ground Cover bloom this year ?
A If planted in the spring, most of the plants will bloom. If planted in the summer or fall, none of the plants will
bloom the same year. However, summer and fall plantings will bloom quite well
the next year, and the following year they should all bloom heavily.
Q Will Penny's Worth Ground Cover grow out of the bed into my lawn ?
A No. Penny's Worth will stay exactly where it is planted. The clumps will expand slightly in size,
but they do not have rhizomes to extend themselves into new ground. They are not invasive.
Q Should I remove old blossoms ?
A The old blossoms will dry and fall off in 2-3 days. If you require a very tidy appearance for a
special occasion, you might wish to remove them by hand that morning.
Q Should I cut back the leaves in the fall ?
A No. In most situations the dying leaves of fall and winter will not be ugly and will create a
good mulch for the following spring. This will suppress future weed growth.
Q Should I cut back the leaves in the summer ?
A Not normally. Sometimes it is recommended to cut the foliage back to 3-5 inches following the
flowering period. This is not at all necessary, but the continuing growth of fresh young leaves would
show more fully. The overall effect would be of bright new foliage.
Q Should I remove flower stalks after they bloom ?
A No. There is no need to do this, though it would improve the appearance of your Ground Cover planting.
If you choose to cut back the foliage in the summer (cf. previous Question), then you will want to cut back the
flower stalks also.
Q Do I need to remove seed pods ?
A No. If a few seed pods do form, however, removing them would give a slight boost in growth.
Also, in very mild winter climate areas, removal of occasional seed pods would eliminate the slight possibility
of seeds falling to the ground, germinating, and growing into new plants of different appearance.
