Spring Blooms

July: Butterfly Weed

Butterfly weed has a PR problem, because if all you hear is its name, the weed part is a bit of a turnoff. But it‘s a gorgeous addition to any perennial garden, and pollinators absolutely love it. It’s a tough plant too, which makes it a favorite for rain gardens, bioswales, and low-maintenance, natural style perennial borders.

Brilliant orange flowers in huge clusters up to nine inches across bloom from the center out in July. The stems below the flowers can be a bit bare and thin, so it’s a good middle-layer plant rather than something you plant right at the edge of a bed. You may know butterfly weed best as the monarch butterfly plant - plants in this genus are the only food source for monarch caterpillars. With fewer and fewer wild places where butterfly weed can grow naturally, bringing these plants into our yards is vital to keeping the gorgeous orange butterflies around.

June: Tulip Tree

Tulip tree, also known as tulip poplar is Indiana’s state tree. It’s also an attractive, landscape-friendly shade tree that grows at a decent pace and is native to Indiana. Plus it has cool-looking flowers that are a huge hit with bumblebees! It’s a winner all around, as long as you have the space and sun it needs.

Tulip tree became the Indiana state tree in 1931. It was selected for its stately size and form and because it can be found all over the state in mature forests. Tulip trees can become truly massive with trunks over 4’ across. The record-holder for Indiana has a trunk diameter of 280”, or nearly 7.5’ in diameter, and is over 100’ tall. Native Americans used the large trunks to make dugout canoes, and the wood is sometimes used to build furniture today. While tulip trees don’t have many serious pest or disease problems, when they’re under stress they can become susceptible to aphids and tulip tree scale. If you see sticky residue on leaves or on the ground under the tree, take a look at younger stems for tan lumps or aphids, and contact a tree care professional or landscape company with tree experience for diagnosis and treatment.

Common Name: Tulip Tree or Tulip Poplar

Scientific Name: Liriodendron tulipifera

Light: full sun

Size: 60-90’ tall, 30-50’ wide

Bloom Time and Color: green tulip-shaped flowers with cream and orange markings in early summer

Notable Varieties: ‘Majestic Beauty’ (variegated leaves with chartreuse margins

Soil: tolerates clay soil

Other Notes: good golden-yellow fall color, pyramidal form, native to Indiana

May: Bluestar

There are a lot of perennials that I think deserve more attention. Bluestar is definitely one of them. This plant has an informal but not messy look, blooms earlier than most perennials, stays put where it’s planted, and has brilliantly golden fall color.

There are a handful of species in the genus Amsonia referred to as bluestar that grow naturally in different regions of the U.S. The two that are easiest to find for sale in the Midwest are Amsonia hubrichtii and Amsonia tabernaemontana, and A. tabernaemontana is also native to our region. They all have in common clusters of pale blue flowers and yellow fall color. The main difference is in foliage texture: A. hubrichtii has an airy, fine texture while A. tabernaemontana has a more substantial presence with wider leaves. They are good for massing in mixed perennials beds, and pollinators love the late spring flowers.

Common Name: Bluestar

Scientific Name: Amsonia species, hybrids, and varieties

Light: full sun

Size: 2-3’ tall and wide

Bloom Time and Color: pale blue flowers in May

Notable Varieties: ‘Blue Ice’ (dwarf variety of A. tabernaemontana), ‘Storm Cloud’ (variety of A. tabernaemontana with smoky purple stems and emerging foliage and deeper blue flowers)

Soil: doesn’t like waterlogged soil, but can take a lot of water if it drains quickly

Other Notes: native to Indiana, deer resistant, pollinator-friendly, good fall color

April: Flowering Dogwood

April: Flowering Dogwood

If you ask someone what their favorite tree is, there’s good chance that they will name a spring-flowering beauty. And of those spring bloomers, flowering dogwood is a classic crowd-pleaser. With its snowy white or soft pink blossoms, flowering dogwood stands as a sign that spring has fully arrived at last.

March: Fragrant Sumac

March: Fragrant Sumac

Fragrant sumac is an adaptable, low-maintenance shrub perfect for even the toughest situations. It thrives even planted in clay, surrounded by asphalt, and battered and dried by full sun. It spreads to form colonies that retain slopes and block out weeds. As long as you don’t plant it in a bog, it will hold the line and even bring some spring and fall surprises just about anywhere.

March: Epimedium

March: Epimedium

This month's featured plant is one of my favorite perennials. Epimedium is a adaptable, four season, shade loving, drought tolerant spreading perennial that makes a great bed edge or groundcover. Did I mention that it has almost no pest and disease problems, and that deer and rabbits leave it alone? And it has unique spring flowers. It deserves a spot in any landscape with shade, and it's truly a shame it isn't more widely known in Indiana.

April: Serviceberry

April: Serviceberry

Our favorite spring-blooming tree here at 317Grow is probably Serviceberry. The white flowers are a crowd-pleaser, the dark red berries are delicious, the fall color is unbeatable, and it's a native species for Indiana. It's hard to get much better than that. There are a few different species of Serviceberry growing in North America. The Canadian Serviceberry sticks closer to the east coast, while the Allegheny Serviceberry extends inland all the way to Minnesota and Iowa. 

March: Flowering Quince

March: Flowering Quince

Flowering Quince starts blooming in shades of pink, salmon, white, and red in March before the leaves emerge. The flowers continue to shine as the foliage comes in, and then they develop into small, edible fruits with a tart taste. The shrub develops into a low, relaxed shape as it ages with an airy structure. Flowering Quince is a gorgeous addition to the spring landscape, but it is not for the low-maintenance garden. Root suckers need to be pruned back, leaf fungus can be a problem in wet seasons, and plants should be checked for fire blight from time to time.

February: Snowdrop

February: Snowdrop

Few things bring a smile to my face in late winter like the sight of a clump of snowdrops popping out of the ground! They're a welcome reminder that warmer weather is just around the corner. These harbingers of spring are excellent for naturalizing in flower beds and they naturally spread by bulbs underground. Since their leaves die back to the ground by mid spring, it's easy to plant over them with summer blooming plants to keep your flower beds exciting all year long.
