Some smooth hydrangea have a kind of unique flower head. This flower head shape looks like lace, hence the name 'lacecap.’
Unlike the mophead flower head, the lacecap shows a flattened flower head. A small cluster of fertile flowers is at the center of the lace flower head. Sterile flowers that look like petals surround these fertile flowers.
1. Haas Halo
Haas Halo is the protagonist in lacecap smooth hydrangea. Its name is named after Joan Haas.
The Haas Halo (Hydrangea arborescens Haas Halo) is the most oversized flower head of the lacecap smooth hydrangea. Under full sun conditions, its flower head size can reach 8 inches. Its flowers can attract bees and butterflies. Its blooming period is from mid-June to early July.
The stems of Haas Halo are so stout and straight that they will not lodge or break down even at the flowering stage. Its height and width can reach 7 feet. Hass Halo is a hydrangea with a low maintenance cost, which can thrive even in partial shade. If we prune the mature Haas Halo to 4 feet in spring, it can produce more flowers during the blooming period.
Haas Halo prefers acidic or neutral soils that are moist and well-drainage. Its caring is the same as that of other smooth hydrangea. The summer in Florida is hot and humid. However, Haas Halo can handle heat and humidity well with enough water.

2. Marry Nell
Marry Nell is an ancient hydrangea variety.
Its flower head is 6 inches wide and surrounded by double rows of sterile flowers. Marry Nell can rebloom quickly after pruning. The flower head of this plant is relatively small, but the leaves are quite large. Its blooming period is from mid-June to early July.
Marry Nell can grow to 6 feet in height and 9 feet in width. It is very suitable for growing in a partial shade environment. However, its stems are thinner than Hass Halo and may show lodge or break during the blooming.

3. Riven Lace
Riven Lace is not a good choice for gardening. Its leaves are dark green, there are deep incised on the leaves, and the edges of the leaves bend inward. Its blooming period is from the end of June to the beginning of July, and the diameter of the flower head is 5 inches.
Riven Lace can grow to 4 feet high and 5 feet wide. Although it can withstand a temperature of -30 ℉, it is not tolerant of sunlight. Even in an environment of partial shade, sunlight can still burn its leaves. This is the reason why Riven Lace is not fit for gardening.

4. Total Eclipse
The leaves of Total Eclipse are dark green. Its flowers are smaller than those of Haas Halo and Mary Nell, and the diameter of the flower head is only 4.5 inches. Its blooming period is from late June to mid-July.
However, the stems of Total Eclipse are strong enough to support the flower head, and it will not break off even in heavy rain. If we prune Total Eclipse before its new buds sprout, the flower head will increase in diameter, and the flowers will bloom more densely. At the same time, its leaves will grow bigge, and the color will become darker.

My name is Arthur Mo. I am a gardener who loves gardening so much. I graduated from Ocean University of China. After I returned to Japan, I began to learn how to cultivate hydrangeas and daisies. Mr. Mitsuhiro (my master) taught me to sow, cut, fertilize, and manage diseases and pests. For nine years, I have been sharpening my planting skills. In 2022, my family and I moved to Florida. The warm climate of Florida gives me the impulse to continue cultivating hydrangeas and daisies. I began my gardening trip in my backyard and unswervingly contributed my efforts to these plants. I love these plants deeply, and at the same time, I also thank my family, my master, and friends for their understanding and support.
