Lovely blooms

I thinned my purple dome asters out some this past year in the hopes to get a little bigger flowers. They were getting so thick and I think they were over crowded. Lots of flowers though!

Hi Diane,

Thank you so much for sharing your experience with your Purple Dome New England Asters! It sounds like your thinning strategy was right on track—overcrowding can definitely limit how large and vibrant the flowers get. You did a great job giving your plants the space they need, and we’re thrilled to hear you still enjoyed lots of lovely blooms!

For continued success, a good tip is to thin asters early in the season by selecting the healthiest, strongest stems to grow out fully. Also, ensuring consistent watering and light feeding can boost flower size and overall plant health. If you need any guidance on fertilizer options or watering schedules, please don’t hesitate to reach out.

Thanks again for your thoughtful feedback. We’re rooting for your asters to blossom their brightest year after year!

Dear Diane,

Thank you so much for sharing your experience with your Purple Dome New England Asters! It’s wonderful to hear that your thinning efforts encouraged lots of lovely blooms—crowding can definitely make it tough for flowers to reach their full size. You did a great job by spacing them out, which helps air circulation and allows each plant to thrive.

For an even bigger floral display next season, you might consider deadheading spent flowers regularly to encourage continuous blooming, and making sure they’re planted in well-draining soil with plenty of sunlight. These asters typically love full sun and benefit from consistent moisture without being waterlogged.

If you’d like, we also have care guides and planting tips on our site that could help you optimize the health and size of your asters in the coming years.

Thanks again for your thoughtful review and happy gardening!

Dear Lind,

Thank you so much for sharing your wonderful experience with the Purple Dome New England Aster! We're thrilled to hear that it’s bringing such vibrant purple hues and abundant blooms to your yard. These asters truly have a way of adding that perfect pop of color and cheer.

If you're interested in making their color even more pronounced or encouraging continuous blooming throughout the season, placing them in full sun with well-drained soil is often a big help. Regular deadheading can also promote additional flower production. And if you ever want to pair them with complementary plants, some late-season pollinator-friendly companions like goldenrod or switchgrass really bring the garden together beautifully.

We're so happy the Purple Dome is thriving for you—thank you for letting us be a part of your gardening journey!

Wishing you happy planting,

Frequently Asked Questions

How tall and wide does Purple Dome New England Aster grow at maturity?

  • Purple Dome New England Aster reaches 1-2 feet tall and spreads 2-3 feet wide at maturity. Its compact, rounded growth habit makes it perfect for front borders or containers where you need late-season color without overwhelming smaller spaces.

How should I care for Purple Dome New England Aster, including watering and fertilizing?

  • Purple Dome New England Aster thrives with minimal maintenance once established. Water regularly the first season, then only during dry spells. Light spring fertilizer encourages growth, but these hardy natives adapt well without heavy feeding. Shop at Nature Hills for this low-care pollinator favorite.

When and how do I pinch back Purple Dome New England Aster to encourage bushier growth?

  • Pinch back Purple Dome Aster in late spring to early summer when plants reach 6-8 inches tall. Remove the top 2-3 inches of growth to encourage branching and create a fuller, more compact 1-2 foot mound. Stop pinching by mid-July to ensure fall blooms.

How often should I divide Purple Dome New England Aster plants?

  • Purple Dome New England Asters should be divided every 3-4 years in early spring or fall. These fast-growing perennials benefit from division to maintain their compact 1-2 foot mounded shape and vigorous blooming. Divide when clumps become overcrowded or the center starts dying out.

Is Purple Dome New England Aster deer resistant or do I need to protect it?

  • Purple Dome New England Aster is naturally deer resistant, inheriting this trait from its native heritage. The plant's natural compounds typically deter browsing deer while attracting beneficial pollinators. You can plant with confidence, though additional protection may help in areas with severe deer pressure.

Can Purple Dome New England Aster be grown successfully in containers?

  • Purple Dome New England Aster thrives in containers and makes an excellent patio plant. This compact perennial grows 1-2 feet high and 2-3 feet wide, perfect for spilling over pot edges. Use it as a solo specimen or mix with other fall bloomers for late-season color.
