Is Angel Pelargonium a Perennial? Getting to the Root of This Common Garden Question

One of the most popular flowering plants for gardens and containers is the angel pelargonium. These beautiful plants have colorful blooms and wonderful scents that have made them a favorite for generations of gardeners. But many people wonder if angel pelargoniums are really perennials. In this article, we’ll look at this question in more depth and get to the bottom of it.

What Are Angel Pelargoniums?

Angel pelargoniums, sometimes called angelwing geraniums, are a group of tender perennial plants native to South Africa. There are over 200 varieties of angel pelargoniums, featuring flowers in shades of pink, purple, red, orange, white and bicolors. The flowers have two upper petals and three lower petals. Many varieties are scented, emitting lovely rose, mint, nutmeg or lemon fragrances.

Angel pelargoniums are prized for their low maintenance requirements, long flowering season, and ability to thrive in containers. Popular varieties include Pelargonium ‘Henry Weller’ with deep purple blooms, ‘Sugar Plum’ with lavender-pink flowers, and the lemon-scented ‘Imperial Butterfly.’ The lacy, cherry-shaped leaves add unique texture.

Are Angel Pelargoniums Perennials?

This is where things get tricky. The simple answer is no – angel pelargoniums are not cold hardy perennials that survive freezing winters in most climates. They are native to the warmer regions of South Africa. Once temperatures drop below 50°F, angel pelargoniums will die back to the ground.

However, that doesn’t mean you can’t enjoy them year after year! Angel pelargoniums are tender perennials or subshrubs. In frost-free climates like USDA Zones 9-11, they will thrive for many years. Angel pelargoniums can reach up to 3 feet tall and wide when happy.

In colder zones, gardeners can overwinter angel pelargoniums indoors and treat them as annuals. Taking stem cuttings in late summer or early fall allows you to propagate new plants each year. Place the cuttings in a sunny spot and wait for roots to form before replanting in spring after the last frost.

How to Grow Angel Pelargoniums

Angel pelargoniums need full sun exposure and well-drained, slightly acidic soil to thrive. Here are some key tips for growing success:

  • Plant in containers or raised garden beds with excellent drainage. Avoid waterlogged soil.

  • Water thoroughly only when the top few inches of soil become dry. Too much moisture causes root rot.

  • Feed every 2-3 weeks with a balanced liquid fertilizer during the active growing season.

  • Prune back leggy stems in midsummer to encourage bushy new growth. Deadhead spent blooms.

  • Bring potted angel pelargoniums indoors before temperatures drop below 50°F at night. Take cuttings to overwinter.

  • Watch for aphids, mealybugs, mites and other pests. Treat promptly to avoid spreading.

  • Allow plants to go into dormancy over the winter by watering them less and letting the soil dry out between waterings.

Angel pelargoniums will bloom for months if you take good care of them. Put pots and baskets where you can enjoy their beauty and scent every day.

Overwintering Tips for Continuous Enjoyment

The key to growing angel pelargoniums year after year is overwintering them indoors in colder climates. Here are some tips:

  • Take 4-6 inch stem cuttings from the tips of healthy stems in late summer/early fall.

  • Remove the lower leaves and dip the cut ends in rooting hormone powder.

  • Stick cuttings in moist propagation mix like perlite or peat.

  • Keep the cuttings warm (65-75°F) in bright, indirect light while roots develop.

  • Once rooted, pot up the new plants and grow them on. Pinch back tips to encourage bushiness.

  • Transition the new plants slowly to the outdoors in spring after the last frost.

  • Set them in a sheltered, sunny spot and avoid cold winds or frost.

  • Resume regular watering and fertilizing as plants become actively growing.

As long as you do these things every season, you’ll always have beautiful angel pelargoniums. Also, cutting these beautiful plants is a great way to give them to other gardeners.

Common Problems With Angel Pelargoniums

When provided with suitable growing conditions, angel pelargoniums are relatively resistant to pests and diseases. But here are a few potential problems to watch for:

  • Root rot due to overwatering

  • Powdery mildew, leaf spots and other fungal diseases

  • Pests like aphids, mealybugs, vine weevils, and whitefly

  • Leggy, stretched growth from insufficient sunlight

  • Leaf scorch, browning leaf edges from intense sun/heat

  • Premature bud drop or failure to bloom from cool temperatures

Catch issues early and make adjustments to resolve the underlying cause. Improving air circulation, pruning affected stems, and treating pests can help minimize damage.

The Takeaway: Enjoy Angel Pelargoniums Year-Round

Angel pelargoniums are tender perennials that can be grown as annuals in colder climates. Although they aren’t true perennials that survive freezing winters, they can be overwintered indoors and propagated each year. With their long bloom season, scented options, and ease of propagation, angel pelargoniums are a must-have for gardens and patio containers. Give them full sun, excellent drainage, and overwinter cuttings for nonstop beauty and fragrance in your garden.

Where to grow Angel pelargoniums

Given their need for good air circulation, as well as their habit and profusion of flowers, pelargoniums make ideal specimen plants. Grow them in individual pots on tiered displays or steps leading to a sunny front door; against brick or natural stone; atop plinths in classical or contemporary pots; or in table displays.

They look good with plants that have silvery or gray leaves, like Helichrysum, Lavandula angustifolia ‘Peter Pan’ with its dark purple-blue flowers, Senecio cineraria ‘Silver Dust,’ clipped Santolina chamaecyparissus, or Dichondra argentea ‘Silver Falls. They also look beautiful next to plants with darker leaves, like Ophiopogon planiscapus ‘Kokuryu, or against Calibrachoa Can-can Double Blue. Dark evergreens, such as Hedera helix ‘Baltica’ or Taxus baccata, complement or contrast.

Angel plants need a lot of light, but if they are grown in a greenhouse, they should be kept out of direct sunlight so they don’t get burned. Plants grown outdoors need direct sunshine to flourish.

Angel pelargoniums grow very happily in peat-free compost, or if you prefer, in a 50:50 mix of multi-purpose compost and peat-free John Innes No. 2. Grow them in terracotta pots.

Err on the dry side when watering and avoid overwatering; soak the root ball, and allow the compost to dry out before watering again. For the best floral displays, feed with half-strength tomato feed or other high-potash feed every time you water during active growth. Pinching out is essential to create dense, bushy plants. Always leave three active nodes, then pinch out with your thumb and fingernail or use sharp scissors.

Start to encourage growth in mid-spring with a little water, gradually increasing the volume as growth increases. Once the plants have started growing, feed with half-strength general fertiliser, then change to high-potash tomato fertiliser once they are in active growth.

How to grow Angel pelargoniums

Angel pelargoniums are easy to grow. The key is to provide at least 2.5cm of space around them to allow good airflow. They should be planted individually in pots – place too many plants around them and they die back. In warmer climates they can be grown outdoors all year round, and in cool temperate locations they make wonderful outdoor summer displays.
