How to attract butterflies in your concrete jungle garden?
The butterfly said to the sun, "They can't stop talking about my transformation. I can only do it once in my lifetime.
If only they know they can do it at any time and in countless ways." — Dodinsky
Yes, just like our own self, we can transform our home garden too at any time and in countless ways. Most if not all of them require some investment in the form of effort, time and money. But one of the easiest ways to make your garden's ecosystem thriving with life, colour and beauty is to create an environ that attracts butterflies.
To attract butterflies into your garden, you need to think like one. If you were a butterfly, you would have loved to hover around nectar-producing plants. That's a given. What else you would have preferred with a lifespan of one to two weeks, unless of course you were lucky enough to be the Brimstone Butterfly (the longest living species in the world with a lifespan of up to 13 months)? If you were a Mourning Cloak, some tropical Heliconians, Red Admiral, or a Monarch, living in your ideal habitat outside of the prying eyes of predators, you get at about nine months under the sun. And boy, if you were one of those tiny ones making those blink-and-you-miss appearance, you might have got just 24 hours to live a lifetime. Even though Tagore said that "The butterfly counts not months but moments, and has time enough", you probably won't hear him as a butterfly! So you need to hurry up!
For example, as The Red Pierrot, a strikingly beautiful tiny butterfly often found in urban settlements in India, you would be often seen fluttering in backyards on flowers of plants like the Periwinkle or the Sadabahar (as it’s known in Hindi), or on the Jatropha. You would prefer open petal flowers. The larval host plants (The plants that butterfly lay their eggs on are called host plants) that you would usually prefer are known as Kalonchoe laciniata (family of succulents) and Pattarchatta (Bryophyllum pinnatum).
What else? As a cold-blooded creature, any butterfly would thrive in sunlight. Most plants need at least 8 hours of sun to produce nectar. So you would like to stay as eggs in cold climate till the weather shifts in your favour. If you were already an adult butterfly, you would try to migrate or hibernate. Migratory monarchs rely on the sun to know the direction to follow.
"If we were to see like a butterfly, we would look at really bright colors," says butterfly expert Rachel Diaz-Bastin of the Conservatory of Flowers in San Francisco. So as a butterfly, flowers would appear very bright to you and when not sipping nectar with your drinking straw (proboscis), you would enjoy sunbathing and resting on leaves.
Once we know a little bit about their inner world, irrespective of the size of our garden or location (urban, suburb, rural), even when we have a small balcony garden in the middle of a bustling city, we can create a butterfly-friendly space by following certain guidelines. If you only have hanging baskets and pots on windowsills or a terrace garden (most butterflies visit houses only up to a moderate height), you can still follow many of them, as long as the plants receive adequate direct sunlight. I am sharing few tips here :
Create pollinator habitat by planting native ﬂowering species:
Focusing on the native flora is golden. If feasible, take a stroll in the neighbourhood for few days to figure out which plants attract native bees and butterflies, and what are the common species of butterflies in your area. Then you can start thinking about how to bring them in and that's the best way to learn. If you add larval plants (host plants) that caterpillars of those species like to eat or include plants that offers nectar to adult butterflies, automatically the garden will be able to welcome and support butterfly population. A complete butterfly-friendly garden should do both by supporting their entire life cycle.
If you don't have the time and interest to figure things out by your own, it's advisable to consult a local horticulturist about the list of annuals and perennials that support butterflies according to your area of living. Based on my observation, hibiscus (red and white), jungle geranium, sunflower, calendula, poinsettia, chrysanthemum, kalanchoe plants, lavender, bougainvillea, Indian snakeweed, cypress vine, mint, crape jasmine, lantana, red ixora, zinnia, holy basil, milletia pinnata, marigold are good bets for Indian climate. You can try curry leaves (caterpillars of Common Mormon thrive here), lemon/citrus, ginger lily, coriander, passion flower (favourite of Tawny Coster) for host plants.
The greater is the diversity of larval host plants in the butterfly garden, the more will be the number of breeding species.
Check for blooming cycles and try to pick flowering plants that bloom throughout the spring and summer. Varieties are important as different flowering schedules ensure food availability in all seasons. The idea is to plant something that naturally grows in your area instead of introducing non-native plants. This reduces pests and entices butterflies.
Wild indigenous flowering herbs and shrubs, which we often consider as 'weeds', can be a great attraction for butterflies since they co-adapted with these species for generations.
Most butterflies are highly selective about host plants on which they lay eggs as these plants should provide suitable food sources in future. If space permits, add some vegetable and herbs to encourage butterflies to lay eggs in your garden.
If you have pets around, research before including anything new to your garden. Some butterflies have certain specific chemical requirements. The caterpillar of Plain Tiger butterfly consume Calotropis, an evergreen, perennial and medium-sized shrub of milkweed family. Calotropis procera causes acute toxicity in various plant and animal cells, including human beings. The toxins do not kill butterflies due to low concentration, but over a period of time enough toxicity gets stored in the body, and consequently birds learnt to avoid predation on them as they fall sick. The caterpillars body also get bright and sparkling, indicating toxins in nature. It's best to avoid milkweed if you got pets who take special interest in your garden.
Be open to perform some interplanting experimentation to check what's attracting and repelling what.
Pay attention to flower colours, shapes and fragrance while buying plants from nursery:
Primarily, butterflies are attracted to flat-topped pink, red, orange, yellow, violet and purple flowers.
Try to create foliage grouping by colours and species for easy identification. Plants producing flower clusters offer efficient feeding for butterflies as they don't need to spend much energy flying to some other plant for drinking. Only movement of tongue suffices to drink from florets (small flowers), while having a stable base of petals on which to stand.
Butterflies are near-sighted, so clustering one particular species of plant in a group increases the likelihood of attraction of passing butterflies to your the garden. Daisies, dahlias, sunflowers give them easy access to food and flat landing space.
Butterflies also see in the ultraviolet portion of the light spectrum (which is not detectable by human eyesight), allowing them to view flowers in a way that we cannot. Once they get close to flowers, certain details in the light reflected in the ultraviolet range provide them with important clues about the availability of nectar.
If your garden is spacious, it's best to choose plants for your garden with varieties of flower shapes, so that different-sized butterflies can feel comfortable to land. Some flowers are shaped in a way that allows easy reach by butterflies for nectar, but not all. Swallowtail butterflies, for example, can access to nectar from deep inside the flowers due to its long tongue.
The floral fragrance that attracts humans towards a specific plant may not appeal to butterflies. Even though I've seen butterflies dancing around blooms of my rose bed in the garden, but rose doesn't require cross-pollination as it propagates through stem. Perhaps that's why usually butterflies don't take special interest in roses. However, roses do attract pollinators. So if you want to add roses in your garden, I would suggest to plant varieties of roses to encourage growth of beneficial insect population in order to control unwanted pests. But the aroma of sage, basil and lavender attract butterflies much more.
Select the right spot and accessory:
While an area with abundant sunlight and good air-circulation is the way to go, it's also important to choose a garden space that's not assailed by wind. You can provide wind protection (windbreak) otherwise. While cold-blooded butterflies need the warmth of sunlight as a must, they also appreciate shades that will help them to regulate their body temperature and offer a cool resting place. Also, sheltered place allows caterpillars to pupate. So try to ensure that your garden receives copious amount of morning sunlight while there's canopy cover in the back.
Adding small water container or bird bath in your garden to create wet patches can be a nice addition for butterflies too, specially in dry seasons. No, they won't drink water from these containers. But the males participate in mud-puddling, in which they lap up water from the moist soils and gain necessary nutrients to pass on to females during copulation to create a healthy future generation. So you can facilitate the process by providing a shallow tray, with water and smooth pebbles to land without harming their delicate bodies. Keep these wet patches covered by plants in the surrounding to lower the evaporation. Along with birds and butterflies, other animals also get benefited by this in summer. Make sure to change the water on alternate days to provide fresh supply as bird droppings can infect the water.
