An angelonia care guide for growing these flowers in your garden

Pink angelonia flowers

Angelonia is a beautiful flower with a sweet scent that some say is reminiscent of apples. It grows short flower spikes that bloom in shades of purple, blue, pink, and white. Angelonia’s smaller size and lovely colors make it exceptionally popular for use in container gardens and garden borders. To help you get started growing angelonia for yourself, here is a simple care guide.

Planting angelonia

When growing it outdoors, begin planting your angelonia in mid-spring. Although mature angelonia plants can tolerate some cold weather, colder temperatures slow down the germination of their seeds.

You can start angelonia indoors at any time, as long as you keep the seeds and seedlings warm. You can transplant the seedlings in your garden once the weather warms up. If you live north of zone 9, you’ll either need to grow your angelonia in a container or grow it as an annual. Whether indoors or out, make sure your angelonia is growing in full sun and rich, well-draining soil.

Caring for angelonia

Keep the soil moist but not soggy for the first few weeks after planting. Once it is fully established, angelonia is somewhat drought tolerant. However, it does appreciate consistent watering. Applying a layer of mulch around the base of your angelonia can help with water retention. Mulch is also useful for suppressing weeds.

Feed your angelonia lightly during the growing season with a balanced fertilizer or compost. During the fall, adding leaf mulch or leaf mold to the soil can provide both fertilizer and mulch for your angelonia. When the flowers wilt and die, you can remove them to keep your garden looking neat, but it isn’t strictly necessary. The flowers typically fall off on their own once they’re fully dead.

Common problems and solutions

Angelonia is resistant to most pests and diseases, but it can develop powdery mildew and aphid infestations. Powdery mildew is a fungal infection caused by wet leaves and poor air circulation, and it looks like thin white fuzz or powder on the leaves of the plant. You can prevent this by spacing your plants properly to allow air to flow between them and avoiding watering them from overhead. To treat powdery mildew, apply potassium bicarbonate or a fungicide.

Aphids are small sap-sucking insects are a nuisance in small numbers, but they can cause more serious problems in larger infestations. They can spread certain plant diseases that lead to stunted or discolored growth, and they leave behind honeydew that’s a perfect fuel for fungi. You can treat aphid infestations using insecticidal soaps. Aphids are also a major food source for ladybugs, so attracting ladybugs to your yard can keep the aphid population in check.

Angelonia is a gorgeous and easy-to-grow flower that can brighten up any garden. Its hardy nature and resistance to most pests mean you can grow it without worry. Whether you plan to grow yours indoors or out, you’ll be delighted by the fragrant and colorful blossoms of angelonia.

Pink muhly grass

Although there are countless varieties of grass, so many of them look the same. It can be difficult to find grass that really stands out in your garden. That’s where ornamental grasses come in. Ornamental grasses like pink muhly grass, purple fountain grass, and switchgrass can add color and texture to your garden borders just like flowers would. Wondering which ornamental grass to choose for your garden? Here are a few of our favorites!
What makes a grass ornamental?
You may think that all grass is ornamental. After all, we grow lawns because they look nice, not because we use them for food. You wouldn’t be entirely wrong in thinking that. Ornamental grass is still grass; it’s just grass that looks different. However, ornamental grass includes grass-like plants such as sedge, as well as true grass varieties.

Ornamental grasses come in a range of appearances besides the short, green look of classic lawn grasses. Often, ornamental grasses are tall, with some growing to 15 feet tall or more. Many are colorful and patterned, and they may have an interesting flower or seed head. Since there are so many varieties, there are ornamental grasses that will fit almost any garden or yard. Many gardeners use ornamental grasses as borders, but some varieties can make great additions to container gardens or flower gardens.

Take advantage of hydrangeas’ color-changing quirk – how to get beautiful blue hydrangeas
Make your soil acidic to turn your hydrangeas a beautiful blue color
Hydrangeas with blue flowers

Hydrangeas are known for two things -- impressive, showy flowers and their tendency to change color based on the pH of the soil. This makes them highly appealing, but also unpredictable. If you don’t take the soil into account, your bright blue hydrangeas could turn out to be pink or purple instead. With careful planning, you can take advantage of this quirk to ensure your hydrangeas are the striking shade of blue you want them to be.
Getting started
First, check what variety of hydrangeas you have. Not all hydrangeas change color! Bigleaf hydrangeas, especially the mophead and lanceleaf cultivars, are the ones that change color. However, white hydrangeas of any variety will not change color.

Test the soil’s pH before you get started. This lets you know how much you’ll need to change it, or if you need to change it at all. If your soil pH is already between 5.5 and 4.5, it’s acidic enough to turn your hydrangeas blue.
