What Is A Lacecap Hydrangea?

Lacecap hydrangea is a member of the family Hydrophyllaceae, which includes such plants as water lilies, water hyacinths, and other members of the genus Hydnusa. It belongs to the subfamily Cactaceae (Cactus Family).

The leaves are small, oval or heart shaped, with four leaflets at the base. They have five petioles and three stamens. The flowers are white or pinkish purple and grow up to 4 inches tall and wide.

These flowers contain two sepals each containing 5 to 8 tiny black seeds. The seed pods resemble miniature pears, but they do not taste sweet like regular pears! Instead they smell strongly of lemon and bitter almonds!

How To Prune Lacecap Hydrangea?

There are many different types of lacy caps, some of them are very large and others smaller than a dime. Some lacey caps are quite easy to prune while others require special care. Let’s see what kind of care we need to take care of our lacescap hydrangeas.

How To Prune Lace Cap Hydrangea?

A lot of gardeners get confused while pruning a lacecap hydrangea. But it is not a very difficult process, just keep these simple steps in mind while pruning your lacecap and you should be fine!

Step 1) Cut off any dead wood on the plant

Step 2) Cut off any weak, spindly, or thin branches. These are easy to spot as compared to the strong branches. Just remember, the thinner the branch; the easier it will break.


3) After cutting off all the weak and spindly branches, you need to cut out some of the thickest branches.

These branches are easy to spot as well. Just look for the biggest, thickest branches and prune them down to around 3 inches in length. Make sure that you don’t remove any of the outermost edges of the shrub.


4) After pruning, you should see a lot of holes in your shrub.

Dont worry, just remove the leaves from the inside of the shrub and keep it for next year. This is called “holing” and helps promote new growth on the outside of the shrub.


5) Next spring just cut back all the new growth that has grown and repeat steps 2-4.

When To Prune Lacecap Hydrangea?

Many people think that you should prune hydrangeas in the fall. But this is not true, it actually is better to prune them in early spring before the plant starts growing. If you prune them in the fall, they won’t have enough time to regenerate before the cold winter months hit. This will weaken the plant and leave it susceptible to damage from the winter weather.

Planting Lacecap Hydrangea

Obviously, lacecap hydrangeas need to be planted in a hole in the ground! But there are some special things to consider when planting your lacecap.


1) Find a location that is partially shaded and has well drained soil.

If you have heavy clay soil, it would be best to add some organic matter such as peat moss or compost to the soil before planting. This will help with drainage and prevent the shrub from drowning.


2) Dig a hole twice as wide and just as deep as the root ball of the shrub.

This will prevent the shrub from falling over after you plant it.


3) Fill the bottom of the hole with sand, gravel, or even broken pottery to prevent the hole from filling with water.

4) Carefully remove the lacecap from its pot.

Try not to disturb the roots too much as you don’t want the plant to lose too many roots.


5) Fill in the hole halfway with soil.

Plant the shrub and fill in the hole with the rest of the soil. Pat down the soil firmly around the shrub, but don’t push so hard that you damage the roots.


6) Water the plant well.

After planting, your lacecap should be good for several years if you prune it correctly. It should slowly grow over time and spread out to create a nice bit of fullness in your yard!
